Module 18: SDK Reference

Flat lookup table for the SDK: signatures, parameters, return types, and which action module has the full context.

This reference describes the SDK release built for the current contract set (several mains, presale, the staking vault, tranche markets, one Up/Down contract). Earlier SDK versions target the previous contracts and cannot be used with this deployment.

Which version these docs describe. They describe the contract set published at /contracts.json (network, chainId, deploymentBlock) and the SDK and MCP releases that ship with it. Install the SDK-TS, SDK-PY and MCP-TS versions named in the release notes of that deployment. An older SDK stops at start-up with an address-mismatch error against /contracts.json: that error means 'upgrade'.

This is the "what is the signature for extendLoan()" reference. No strategy, no examples: just the API surface. For usage patterns, errors, and worked examples, follow the Action Module pointer. Every row names the contract call the method makes; the wrapper names follow the SDK release and may still change, the contract calls do not.

Examples name STASIS and USDG as "the default main and its pair asset". Every main has its own on-chain name and symbol and its own pair asset: read them, never assume them.

→ See Module 02 for getting started
→ Contract addresses: GET /contracts.json on the deployment you use (Module 17 explains the keys)
→ See Module 10 for all read/query patterns

Section 1: Overview & Installation

JavaScript

npm install github:Launch-On-Basis/SDK-TS

Python

pip install git+https://github.com/Launch-On-Basis/SDK-PY.git

Initialization

const client = await BasisClient.create({ privateKey?, apiKey?, rpcUrl?, chainId?, apiDomain?, addresses? })

On start the client reads GET {apiDomain}/contracts.json: one address per contract, the chainId, and a mains list (main, pairAsset, vault, pairSymbol, pairDecimals). addresses overrides that set. The mains can also be read on chain: SWAP.pairCount(), pairList(i), pairs(main) → (pairAsset, staking, active). An address that is zero in that file is not deployed on that network: the client refuses to send a transaction to it. rpcUrl is optional: when it is left out the SDK uses the default public RPC of the chain named in /contracts.json; pass your own for anything beyond light use.

Client Modes

Mode	Config	Capability
Read-only	`{ rpcUrl? }`: no key	On-chain reads only
API-key	`{ apiKey, rpcUrl? }`	Off-chain API reads, no writes
Full	`{ privateKey, rpcUrl? }`	All reads and writes

Token Amounts

Tokens minted by BASIS (every main, factory token, market token, outcome share and Up/Down pool token) are 18-decimal wei. An amount of a main's pair asset uses that asset's decimals: read PAIR_UNIT() on the main, decimals() on the asset, or pairDecimals in /contracts.json. Resolver bonds use BOND_UNIT() of BOND_TOKEN(). parseUnits("5", 18) is 5 units only of an 18-decimal asset; USDG, the default main's pair asset, has 6 decimals, so 5 USDG is parseUnits("5", 6). Return values are bigint in the unit of the asset they measure.

Approvals and msg.value

Approve the exact amount of the token a call pulls, to the contract that pulls it. The vault itself is not a token and has no approve.

Call	Token pulled	Spender
buy, `leverageBuy`, `mixedBuy`	`path[0]`	SWAP
sell	the token sold (`path[0]`)	SWAP
`swapCross`	`path[0]` (nothing when the native coin is sent as `msg.value`)	SWAP
vault `stake`	the main	the vault
vault `repay`, paid `extendLoan`	the main's pair asset	the vault
hub `takeLoan`, `increaseLoan`	the collateral token	the loan hub
hub `repayLoan`, `extendLoan` with `payInStable`	the ecosystem's stable (the main's pair asset)	the loan hub
leverage repay through SWAP (`repayWith`)	the token you pay with (the pair asset or another)	SWAP
leverage repay or paid extension by contract call	the pair asset	the address you call (the SDK sets the approval)
resolver propose, dispute, veto	`BOND_TOKEN`	the resolver
market `buy`	the input token	the market's host
order fill (`buyOrder`)	the market's pair asset	the market's host
market seed (`createMarket`)	the main's pair asset	the host
Up/Down bet	the input token	MultiPrediction
vesting create, add tokens	the vested token	the vesting contract
vesting `repayLoanOnVesting`, `repayExtendAndReborrow`	the pair asset of the vesting's main (the loan's full amount)	the vesting contract

Payable calls: token creation and market creation need msg.value equal to the fee exactly; vesting creation needs at least its fee when that fee is on (the surplus is refunded).

Section 2: Methods by Module

client (core)

Method	Params	Returns	Description	Action Module
`BasisClient.create(config)`	`{ privateKey?, apiKey?, rpcUrl?, chainId?, apiDomain?, addresses? }`	`BasisClient`	Initialize client	02
`client.authenticate()`	-	`session`	SIWE auth	03
`client.ensureApiKey()`	-	`apiKey`	Provision API key	03
`client.getSession()`	-	`session`	Check session	03
`client.logout()`	-	`void`	End session	03
`client.writeContract(params)`	`ContractWriteParams`	`tx+sync`	Execute, then index the transaction (every event)	10

client.trading

Each main trades against its own pair asset and each factory token against its main. pairAsset below is SWAP.pairs(main).pairAsset; a token's main is token.quoteToken(). A factory token paired straight with the pair asset is refused (Bad pair).

Method	Params	Returns	Description	Action Module
`buy(tokenAddress, amountIn, minOut?)`	`address, bigint, bigint?`	`tx`	Buy a token with its main's pair asset. Calls `ASwap.buyTokens(amountIn, minOut, [pairAsset, main, token], false)` (`[pairAsset, main]` when the token is a main). `amountIn` is in the pair asset's decimals.	04
`sell(tokenAddress, tokenAmount, minOut?)`	`address, bigint, bigint?`	`tx`	Sell a token for its main's pair asset: `ASwap.sellTokens(tokenAmount, minOut, [token, main, pairAsset], false)`.	04
`sellPercentage(tokenAddress, percentage)`	`address, number`	`tx`	Sell % of balance	04
`leverageBuy(tokenAddress, amountIn, days, minOut?)`	`address, bigint, number, bigint?`	`tx`	Open a leveraged position: `ASwap.leverageBuy(amountIn, minOut, path, numberOfDays)`. `path[0]` must be the pair asset of `path[1]` (the main), else `wrong path`. `minOut` is checked against the whole leveraged collateral (`simulateLeverageLocked(…).totalColleteral`). Leverage reaches up to about 37x, depending on the token and the size of the buy; the position must be more than 2x (`Under 2x`). One open position per token: with one already open, a leverage buy adds to it and keeps its end date, priced for the days left (`Extend first` when fewer than the minimum days are left).	04
`mixedBuy(tokenAddress, amountIn, days, percentageLeverage, minOutLev?)`	`address, bigint, number, number, bigint?`	`tx`	One leverage position at a lower leverage: `ASwap.mixedBuy(amount, minOutLev, path, numberOfDays, percentageLeverage)`. The whole amount goes into the position, and only `percentageLeverage` % (1 to 99, else `Range`) of the first buy is borrowed against; the rest stays in the position as collateral with no debt. Nothing goes to the wallet. `minOutLev` is the minimum tokens in the position (`simulateLeverageLocked` or `simulateLeverageFactoryLocked` with that percentage, `.totalColleteral`). Same fees, the same 2x minimum and the same one-position-per-token rule as `leverageBuy`.	04
`buyTokens(amountIn, path, minOut?, wrapTokens?)`	`bigint, address[], bigint?, boolean?`	`tx`	Raw buy: `ASwap.buyTokens(amount, minOut, path, wrapTokens)`. Paths: `[pairAsset, main]`, `[main, token]` (the amount and the tax are then in the main) or `[pairAsset, main, token]`. `wrapTokens = true` stakes a bought main in that main's vault. SWAP picks presale or AMM itself.	04
`sellTokens(amountIn, path, minOut?)`	`bigint, address[], bigint?`	`tx`	Raw sell: `ASwap.sellTokens(amount, minOut, path, false)`. The fourth contract argument must be `false` (`true` reverts `use swapCross`). Paths are the reverses of the buy paths.	04
`swapCross(path, amountIn, minOut, opts?)`	`address[], bigint, bigint, { recipient?, deadline?, unwrapNative? }`	`tx`	Swap across two mains, or to and from an outside token, in one transaction: `ASwap.swapCross(path, amountIn, minOut, recipient, deadline, unwrapNative)`. Payable: send the native coin with `path[0]` = the wrapped native token.	04
`quoteCross(path, amountIn, wallet)`	`address[], bigint, address`	`bigint`	What a trade pays after `wallet`'s tax, for plain and cross-pair paths. The contract function is nonpayable, so it is called with `eth_call`. Reverts `autovest presale` for a token in an auto-vest presale. Use it to set `minOut`.	04,32
`getAmountsOut(amountIn, path)`	`bigint, address[]`	`bigint`	Quote before tax: one uint256 for 2-hop and 3-hop paths. A buy takes the tax off the input and a sell takes it off the output, so the trade pays less than this.	04,32
`getTokenPrice(tokenAddress)`	`address`	`bigint`	Price × 1e18 in main units. For a main it is the price in its pair asset.	04,10
`getPairPrice(tokenAddress)`	`address`	`bigint`	Price in the main's pair-asset units (token price × the main's price). A USD price only when the pair asset is a USD stable.	04,10
`getLeverageCount(wallet, main?)`	`address, address?`	`bigint`	Leverage positions the wallet has opened on that main (default: the default main). Reads `main.leverageCount(wallet)`; ids run 1 to count. Each position is recorded on its token's main: loop over every main to see them all. `MainLens.getLeverageCountForUserAndToken(main, wallet, token)` counts the positions ever opened on one token; at most one is open at a time (`main.openLeverageOf(wallet, token)`).	04,10
`getLeveragePosition(wallet, index, main?)`	`address, bigint, address?`	`LeveragePosition` (13 values)	`main.leverages(wallet, index)`. Order: `user, token, collateralAmount, liquidatedAmount, fullAmount, borrowedAmount, liquidationTime, liquidationClaim, isLiquidated, active, creationTime, timeOfClosure, (leverageBuyAmount, cashedOut)`. 1-indexed: index 0 is always empty.	04,10
`getPartialLoanSellAmounts(positionId, wallet, percentage, isLeverage, main?)`	`bigint, address, number, boolean, address?`	`{ residualTokens }`	`MainLens.getPartialLoanSellAmounts(main, loanId, user, percentage, isLeverage)` (the main is the first argument). Use only `residualTokens`: the part of your collateral left to sell. Read it before a partial sell to set `minOut`; the other return values are internal. Reverts `Already liquidated` on a liquidated position.	04
`partialLoanSellFor(main, positionId, percentage, isLeverage, minOut)`	`address, bigint, bigint, boolean, bigint`	`tx`	Sell down or close a leverage position; 100 = full close. Percentage 10 to 100 in steps of 10 (`% by 10`, `% range`). `ASwap.partialLoanSellFor(main, loanId, percentage, isLeverage, minOut)` on the main the position lives on. Only the position's own wallet may call (`Not user`). The exit pays 3% of the proceeds above the initial buy. Slippage revert: `Min out not met`. Naming the wrong main reverts `Not user`, or sells that main's position with the same id.	04
`extendLeverage(positionId, days, payInMainPair, refinance, main?)`	`bigint, number, boolean, boolean, address?`	`tx`	Extend a leverage position. The position is recorded on the token's main; extend it there: `main.extendLoan(positionId, days, true, payInMainPair, refinance)`. Works until a keeper liquidates the position.	04
`repayLeverage(positionId, main?)`	`bigint, address?`	`tx`	Repay with the pair asset, nothing sold. The position is recorded on the token's main; repay it there: `main.repayLoan(positionId, amount, true)`. An `amount` at or above the debt closes the position and returns all the collateral (send `type(uint256).max` to close). A smaller amount repays that part and returns the same share of the collateral; what is left must stay at least `minimumLoan` (`Repay in full`). Approve the pair asset to the address you call. Or repay through SWAP: `ASwap.repayWith(main, positionId, tokenIn, amountIn, minPairOut, close, deadline)` takes the pair asset itself or another token (converted to the pair asset first), refunds the leftover, and needs the approval on SWAP only.	04
`claimLeverageLiquidation(positionId, main?)`	`bigint, address?`	`tx`	After a keeper liquidated the position: `main.claimLiquidation(positionId, true)` pays what is left after the debt, less the 10% liquidation fee. Claim within 365 days of the liquidation; after that the leftover may no longer be claimable.	04

ASwap.convertToNative(marketToken, inputToken, inputAmount, sell) converts the pair asset or the main to and from a market token, not outcome shares. Only registered prediction hosts may call it (hosts only); no wallet can. The SDK has no wrapper.

After liquidationTime a keeper liquidates the position. Assume it can happen in the first block after the deadline. Until that transaction lands a repay or a paid extension still goes through; do not plan on the gap.

client.factory

Method	Params	Returns	Description	Action Module
`createTokenWithMetadata(params)`	`CreateTokenParams`	`tx`	Create a token and its IPFS metadata. Sends `msg.value` = `feeWhitelist(wallet) ? 0 : feeAmount()` exactly; any other value reverts `Wrong fee`. `presaleTokens` is a count of whole tokens sold in the presale (0 = no presale), not a pair-asset amount. Calls `createTokenFor(CreateParams)`, or `createReversedTokenFor` when `reversed: true`. Bounds: `hybridMultiplier` 1–100 (100 = Stable+, 50 to 99 = Utility+, 1 to 49 = Floor+; reversed: 1 to 50 Meme+, 51 to 99 Yolo+, 100 Yolo), `startLP` 1,000 to 100,000, `autoVestDuration` 1–990 days, `frozen` needs a presale, `supplyMultiplier` at most the main's `MAX_SUPPLY_MULTIPLIER()`.	07
`createTokenFor(params)`	`CreateParams`	`tx`	The same creation without metadata: picks the main, `supplyMultiplier` and `rewardsEnabled`.	07
`createReversedToken(params)`	`CreateParams`	`tx`	Create a reversed token, Meme+, Yolo+ or Yolo (`reversed()` is true): `createReversedTokenFor`. The presale is at most half the launch supply.	07
`disableFreeze(tokenAddress)`	`address`	`tx`	`token.disableFreeze()`, called on the token. Irreversible.	07
`setWhitelistedWallet(tokenAddress, wallets, amount, tag)`	`address, address[], bigint, string`	`tx`	`token.setWhitelistedWallet(wallets, amount, tag)`. `amount` caps the tokens each wallet may buy during a frozen presale.	07
`removeWhitelist(tokenAddress, wallet)`	`address, address`	`tx`	`token.removeWhitelist(wallet)`	07
`claimRewards(tokenAddress)`	`address`	`tx`	Claim holder rewards: `token.claimRewards()`. Only tokens created with `rewardsEnabled` pay; rewards are paid in the main's pair asset. It never pays a creator.	07
`getTokenState(tokenAddress)`	`address`	`TokenState`	`frozen`, `presaleComplete`, `presaleSold`, `presaleTarget`, `reversed`, `rewardsEnabled`, `hybridMultiplier`, `totalSupply`, the price in main units (`getTokenPrice`) and in pair-asset units (`getPairPrice`), `main`, `pairAsset`.	07,10
`isEcosystemToken(tokenAddress)`	`address`	`boolean`	Verify token is legit	10
`getTokensByCreator(wallet)`	`address`	`address[]`	Factory tokens whose factory caller was the wallet. A market token is created by its host, so a wallet's markets are not in this list.	07,10
`getFeeAmount()`	-	`bigint`	Creation fee in ETH: `feeAmount()`	07
`isFeeWhitelisted(wallet)`	`address`	`boolean`	`feeWhitelist(wallet)`: such a wallet sends 0	07
`getClaimableRewards(tokenAddress, wallet)`	`address, address`	`bigint`	`token.getClaimableRewards(wallet)`; 0 on a token without rewards	07,10
`getFloorPrice(tokenAddress)`	`address`	`bigint`	The floor in pair-asset units: `calculateFloor()`. `calculateTokenFloor()` gives it in main units.	04,10

client.loans

⚠️ These methods act on HUB LOANS only. SWAP opens and closes leverage positions, and each one is recorded on its token's main. The hub methods (repayLoan, extendLoan, increaseLoan, claimLiquidation, hubPartialLoanSell) take a hub id and never reach a leverage position. For leverage use client.trading: partialLoanSellFor(main, positionId, pct, true, minOut) to sell down or close, extendLeverage, repayLeverage, and claimLeverageLiquidation after a keeper liquidation.

Method	Params	Returns	Description	Action Module
`takeLoan(main, collateral, amount, days)`	`address, address, bigint, number`	`tx`	Borrow the main's pair asset against `amount` of `collateral`: `ALOAN_HUB.takeLoan(ecosystem, collateral, amount, daysCount)`. `ecosystem` is the main: the collateral itself when it is a main, else its `quoteToken()`. 10 to 1000 days. The fee, 2% + 0.005% per day, is taken up front. The loan value must reach the main's `minimumLoan`. One open loan per wallet, main and collateral token: add to it with `increaseLoan` (`Open loan: increase it`). Returns a hub id; ids start at 1.	05
`repayLoan(hubId)`	`number`	`tx`	`ALOAN_HUB.repayLoan(hubId, amount)`; nothing is sold. An `amount` at or above the debt closes the loan and returns all the collateral (send `type(uint256).max`). A smaller amount repays that part and returns the same share of the collateral; what is left must stay at least the main's `minimumLoan` (`Repay in full`). To repay with another token: `repayLoanWith(hubId, tokenIn, amountIn, minStableOut, close, deadline)`. Works until a keeper liquidates the loan, even after the term.	05
`extendLoan(hubId, days, payInStable?, refinance?)`	`number, number, boolean?, boolean?`	`tx`	`ALOAN_HUB.extendLoan(hubId, addDays, payInStable, refinance)`. The two flags are exclusive (`Pay in stable or refinance, not both`). `days = 0` needs `refinance`.	05
`increaseLoan(hubId, amountToAdd)`	`number, bigint`	`tx`	Add collateral to the loan: `ALOAN_HUB.increaseLoan(hubId, amountToAdd)`	05
`claimLiquidation(hubId)`	`number`	`tx`	After a keeper liquidated the loan: claim the remainder (the collateral left after the debt, less the 10% liquidation fee). Claim within 365 days of the liquidation; after that the leftover may no longer be claimable.	05
`hubPartialLoanSell(hubId, percentage, minOut)`	`number, number, bigint`	`tx`	Partial sell of a hub loan: `ALOAN_HUB.hubPartialLoanSell(hubId, percentage, minOut)`, in 10% steps (10 to 100). Pays the pair asset, and the residual sold pays the token's normal sell rate (base + creator + rewards fee, no referral). There is no leverage flag: the hub only sells hub loans. For leverage use `client.trading.partialLoanSellFor()`.	05
`getUserLoanDetails(wallet, hubId)`	`address, number`	`FullLoanDetails` (14 fields)	Loan state by hub id. An unknown id reverts `Loan does not exist`.	05,10
`getUserLoanCount(wallet)`	`address`	`number`	`userLoanCount(wallet)`: loans the wallet ever opened on the hub. Ids are 1 to count: loop from 1.	05,10

A vault loan is owned by the vault in the hub: these methods fail for it (use client.vault). After liquidationTime a keeper liquidates the loan. Assume it can happen in the first block after the deadline. Until that transaction lands a repay or a paid extension still goes through; do not plan on the gap.

client.vault(main?)

One vault contract serves every main (SWAP.pairs(main).staking names it). Each main has its own pool, and every contract call names the main first; every SDK method takes an optional main (default: the default main). A stake is not a token: it cannot be transferred or approved, and the vault has no balanceOf: the stake is positions(main, wallet).staked. Rewards: 10% of the base part of every fee on that main's tokens, bought into the main and paid to that main's stakers only. A liquidation settles the vault position in the same transaction: there is no settle call.

Method	Params	Returns	Description	Action Module
`stake(amount)`	`bigint`	`tx`	Stake the main 1:1: `AStasisVault.stake(main, amount)`. Minimum `minStake()`. Approve the main to the vault.	06
`unstake(amount, toMainPair?, minMainPair?)`	`bigint, boolean?, bigint?`	`tx`	`unstake(main, amount, toMainPair, minMainPair)`. At most `freeToUnstake(main, wallet)`: the pledged part stays. With `toMainPair` the main is sold for the pair asset at the wallet's own tax; `minMainPair` is the floor.	06
`claim()`	-	`tx`	`claim(main)`: pay out the earned rewards, in the main. With a loan open, only the part not needed as collateral.	06
`compound()`	-	`tx`	`compound(main)`: add the earned rewards to the stake	06
`borrow(mainAmount, days)`	`bigint, number`	`tx`	Pledge `mainAmount` of the staked main and borrow its pair asset: `borrow(main, stasisAmount, days)`. The first argument is an amount of the main, not of the pair asset. One loan per position; the pledged part keeps earning.	06
`addToLoan(additionalMain)`	`bigint`	`tx`	Pledge more staked main and borrow more: `addToLoan(main, additionalStasis)`. Needs more than 10 days left on the loan (`Duration too short`).	06
`repay()`	-	`tx`	`repay(main)`: repay the vault loan in full. Approve the pair asset to the vault.	06
`extendLoan(daysToAdd, payInMainPair, refinance)`	`number, boolean, boolean`	`tx`	`extendLoan(main, daysToAdd, payInMainPair, refinance)`: extend the vault loan. `daysToAdd = 0` needs `refinance = true` and `payInMainPair = false`.	06
`earned(wallet)`	`address`	`bigint`	`earned(main, wallet)`: rewards earned and not yet claimed, in the main	06,10
`getPosition(wallet)`	`address`	`VaultPosition`	`positions(main, wallet)` = `(staked, pledged, hubId, checkpoint, pending, hub)` (a loan is open when `hub` is set), plus `earned(main, wallet)`, `collateralOf(main, wallet)` and `freeToUnstake(main, wallet)`	06,10
`getAvailableStasis(wallet)`	`address`	`bigint`	`getAvailableStasis(main, wallet)`: stake plus unclaimed rewards the wallet can still pledge	06,10
`getVaultLoan(wallet)`	`address`	`LoanDetails \| null`	The wallet's vault loan, read from `positions(main, wallet).hub` and `.hubId`. The borrower of record on the hub is the vault, not the wallet.	06,10
`getTotals()`	-	`{ totalStaked, totalPledged, rewardsHeld }`	`pools(main)` = `(totalStaked, totalPledged, rewardsHeld, accRewardPerStake)`: that main's pool, in the main	06,10

client.vesting

Method	Params	Returns	Description	Action Module
`createGradualVesting(beneficiary, token, totalAmount, startTime, durationInDays, timeUnit, memo, ecosystem, renounceOnCreation?)`	`address, address, bigint, number, number, number, string, address, boolean?`	`tx`	Linear vesting. `beneficiary` cannot be the zero address (`Invalid beneficiary address`). `startTime` may be at most 990 days ahead (`Start too far`); a past time means now. `ecosystem` is the token's main (the token must be that main or one of its tokens). Payable only when the vesting fee is on and the wallet is not fee-whitelisted (off by default; the surplus is refunded).	09
`createCliffVesting(beneficiary, token, totalAmount, unlockTime, memo, ecosystem, renounceOnCreation?)`	`address, address, bigint, number, string, address, boolean?`	`tx`	Cliff vesting; same `beneficiary`, `ecosystem` and fee rules	09
`batchCreateGradualVesting(beneficiaries[], token, totalAmounts[], memos[], startTime, durationInDays, timeUnit, ecosystem, renounceOnCreation?)`	parallel arrays + one shared token, schedule and main	`tx`	Batch gradual	09
`batchCreateCliffVesting(beneficiaries[], token, totalAmounts[], unlockTime, memos[], ecosystem, renounceOnCreation?)`	parallel arrays + one shared token, unlock time and main	`tx`	Batch cliff	09
`claimTokens(vestingId)`	`number`	`tx`	Claim unlocked	09
`takeLoanOnVesting(vestingId)`	`number`	`tx`	Borrow against the vesting. No days argument: the term is the schedule's remaining days plus `loanBuffer` (10). Pledges every unclaimed token; the beneficiary receives the loan in the main's pair asset.	09
`repayLoanOnVesting(vestingId)`	`number`	`tx`	Repay the vesting loan in full; also settles a loan a keeper liquidated. The beneficiary may call it, and so may the creator while the vesting is not renounced (the caller pays).	09
`repayExtendAndReborrow(vestingId, additionalDays)`	`number, number`	`tx`	Repay, extend the schedule and borrow again in one transaction	09
`renounceVesting(vestingId)`	`number`	`tx`	After it the creator can no longer change the beneficiary, extend the schedule or repay its loan. Adding tokens and handing on the creator role still work.	09
`changeBeneficiary(vestingId, newBeneficiary)`	`number, address`	`tx`	Change recipient (not on a renounced vesting)	09
`extendVestingPeriod(vestingId, additionalDays)`	`number, number`	`tx`	Extend, in days. Creator or beneficiary. Reverts `Loan open: repay first` while a loan is linked.	09
`addTokensToVesting(vestingId, amount)`	`number, bigint`	`tx`	Add tokens (same loan guard)	09
`transferCreatorRole(vestingId, newCreator)`	`number, address`	`tx`	Transfer creator	09
`getVestingDetails(vestingId)`	`number`	`VestingDetails` (14 fields)	Schedule details; `ecosystem` is field 3 and `renounced` is last	09,10
`getClaimableAmount(vestingId)`	`number`	`bigint`	Claimable now	09,10
`getVestedAmount(vestingId)`	`number`	`bigint`	Total vested	09,10
`getEffectiveTotalAmount(vestingId)` / `getEffectiveVestedAmount(vestingId)`	`number`	`bigint`	`effectiveTotalAmount` / `effectiveVestedAmount`: totals after a liquidation reduced the vesting	09,10
`getVestingsByBeneficiary(wallet)`	`address`	`vestingId[]`	My vestings	09,10
`getVestingsByCreator(wallet)`	`address`	`vestingId[]`	Created vestings	09,10
`getActiveLoan(vestingId)`	`number`	`bigint`	The hub id of the linked loan; 0 = none	09,10
`getLoanHubOf(vestingId)`	`number`	`address`	`loanHubOf(vestingId)`: the hub that holds this vesting's loan	09
`getTokenVestingIds(tokenAddress, startIndex, endIndex)`	`address, number, number`	`vestingId[]`	Vestings of a token, paged	09
`getVestingDetailsBatch(vestingIds[])`	`number[]`	`VestingDetails[]`	Batch read	09,10
`getVestingCount()`	-	`number`	`vestingCount()`; ids start at 0	09

client.predictionMarkets

Public markets live on the marketTrading host (ATrancheMarket). Sizes are set per main: read TrancheReader.sizesFor(host, main, n) → (unit, seedStep, minBet, perOutcome, totalPool). The seed floor is minSeed() × unit, in steps of seedStep. The outcome limit is MAX_OUTCOMES(), read live.

Method	Params	Returns	Description	Action Module
`createMarketWithMetadata(params)`	`CreateMarketParams`	`tx`	Create a public market: `ATrancheMarket.createMarket(CreateParams, deadline, approvalSignature)` with the moderator approval (`POST /api/v1/markets/approve`) and exactly the signed name, symbol, end time and outcomes. `CreateParams` = `{ marketName, symbol, endTime, optionNames, trancheBP, maintoken, frozen, bonding, seedAmount }`. `endTime`: 0 for an open-ended market, else at least 1 minute ahead. The end time is part of the moderator approval: an approval is only valid for the end time it was signed for, and the approval step refuses end times too far out. `trancheBP`: 1 to 10 slices that sum to 10000 (`[10000]` = winner takes all). `seedAmount`: raw pair-asset amount, at least `minSeed()` × `sizesFor.unit` and a multiple of `seedStep`. Approve the seed of the pair asset to the host. `msg.value` = the factory fee for the host, exactly.	08
`buy(marketAddress, outcomeId, inputToken, inputAmount, minTokens, minShares)`	`address, number, address, bigint, bigint, bigint`	`tx`	`buy(marketToken, outcomeId, inputToken, inputAmount, minUsdc, minShares, deadline)`; after `deadline` it reverts `Deadline`. `inputToken` is the market token, the pair asset, the market's main or another BASIS token (an outside token only where a route exists). `minTokens` (contract name `minUsdc`) is the smallest net market-token amount accepted; `minShares` comes from `marketReader.quoteShares`. Never pass 0. AMM bets stop once an outcome is proposed.	08
`redeem(marketAddress, opts?)`	`address, { fractionBps?, slices?, minOut? }`	`tx`	`redeem(marketToken, fractionBps, slices, minOut)`; default `(10000, 1, …)`. The payout is held in market tokens and sold to the pair asset here.	08
`buyOrdersAndContract(marketAddress, outcomeId, orderIds[], inputToken, totalInput, minShares)`	`address, number, number[], address, bigint, bigint`	`tx`	Combined order book + AMM. Takes only the pair asset as `inputToken`.	08
`getMarketData(marketAddress)`	`address`	`MarketData`	12 fields. `finalOutcome`: 254 = INVALID, 255 = unresolved. `usdc` is the market's pair asset. `generalPot` always reads 0: do not use it.	08,10
`getOutcome(marketAddress, outcomeId)`	`address, number`	`OutcomeData`	Outcome details	08,10
`getUserShares(marketAddress, wallet, outcomeId)`	`address, address, number`	`bigint`	Share balance	08,10

`quoteScenario(marketAddress, ranking[], tieMask, wallet)`	`address, number[], bigint, address`	`bigint`	Payout in market tokens if that ranking wins	08,32
`quoteRedeem(marketAddress, wallet)`	`address, address`	`bigint`	Payout in market tokens after resolution	08,32
`getPendingPayout(marketAddress, wallet)`	`address, address`	`bigint`	`pendingPayout(market, wallet)`: market tokens still to redeem after a partial redeem	08
`getMarketSizes(main, numOutcomes)`	`address, number`	`{ unit, seedStep, minBet, perOutcome, totalPool }`	`TrancheReader.sizesFor(host, main, n)`: the sizes in force. `minBet` is in 18-decimal market tokens, after conversion and before the fee.	08

Total pot: there is no getter. It is the sum of totalCost over marketReader.getAllOutcomes(host, market), in market tokens; marketReader.valueInUsdb(host, market, amount) gives its pair-asset value.

client.orderBook

Every call goes to the market's own host (public or private).

Method	Params	Returns	Description	Action Module
`listOrder(marketAddress, outcomeId, amount, pricePerShare)`	`address, number, bigint, bigint`	`tx`	Create a limit sell. `pricePerShare` is the odds × 1e18, from 0.001 (`1e15`) to 0.999 (`999e15`), or 0 to sell at the live AMM price.	08
`cancelOrder(marketAddress, orderId)`	`address, number`	`tx`	Cancel order	08
`buyOrder(marketAddress, orderId, fill, maxCost)`	`address, number, bigint, bigint`	`tx`	Fill an order (not your own). `fill` is a share count; `maxCost` caps the total cost in the market's pair asset.	08
`getBuyOrderCost(marketAddress, orderId, fill)`	`address, number, bigint`	`{ baseUsdc, buyerTax, totalCostToBuyer, netToSeller }`	Cost of a fill	08
`getBuyOrderAmountsOut(marketAddress, orderId, amount)`	`address, number, bigint`	`{ fill, baseUsdc, buyerTax, totalCostToBuyer }`	Shares a pair-asset amount buys from that order	08

To sweep several orders use buyOrdersAndContract with the order ids.

client.resolver

Every tranche market registers with the resolver when it is created and is ranked. The single-outcome contract entry points (one uint8 outcome) revert Ranked market: use the *Ranked entrypoints. Only wallets on the voter panel (authorizedVoter) vote: no stake, no lock. Bonds are paid in BOND_TOKEN: 5 units, doubled after each EARLY reset, at most 8 doublings (1,280 units), never above BOND_MAX() (8,000 units). Read requiredBond(market, wallet). The winner gets their own bond back, plus the loser's bond up to twice the winner's own bond (so at most three times their own bond in total). Anything above that goes to insurance. If neither key wins, both bonds go to insurance. When an EARLY dispute wins, the disputer gets their own bond back plus half the proposer's bond; the other half goes to insurance.

Method	Params	Returns	Description	Action Module

For a loan or a trade preview on live state, use trading.getAmountsOut or trading.quoteCross (SWAP.getAmountsOut / SWAP.quoteCross), the token's own calculateFloor(), and the MainLens previews such as getPartialLoanSellAmounts.

client.taxes

One base fee on every trade and bet, TAXES.baseRate() (60 bps today; 54 for a wallet with an on-chain referrer), plus, on a factory token, the creator fee its creator set (at most 1%) and, on a rewards-enabled token, its rewards fee (at most maxRewardsFee). A main pays the base only; a fee-whitelisted wallet pays 0. Read the rate right before trading.

client.updown

One MultiPrediction contract serves every asset of the Up/Down product. client.updown.assets() lists them (assetCount() and assets(i) = (priceFeed, poolToken, paused, label, main, settle, virtFloor)). Assets can be added at any time: do not hardcode the list. asset is the index (examples use 0). tf is 0=5m, 1=15m, 2=1h, 3=4h, 4=24h. On chain side is 1 = Bull, 2 = Bear. Failures are custom errors, except Deadline, fraction 1-10000, slices 1-25 and Below minOut.
