Addresses and Token Accounts - Exponent Docs

Use these helpers to derive market PDAs and user LP token accounts.

Market addresses

const seedId = new Uint8Array([1, 2, 3, 4, 5, 6, 7, 8]);

const derived = TranchingMarket.deriveAddresses(seedId);

console.log("Market:", derived.market.toBase58());
console.log("Return model storage:", derived.returnModelStorage.toBase58());
console.log("SY escrow:", derived.tokenSyEscrow.toBase58());
console.log("Senior LP mint:", derived.mintLpSenior.toBase58());
console.log("Junior LP mint:", derived.mintLpJunior.toBase58());

Field	Description
`market`	Main `ExponentTranchingMarket` PDA
`returnModelStorage`	PDA account storing the active return model
`tokenSyEscrow`	Market-owned SY escrow
`mintLpSenior`	Senior LP token mint
`mintLpJunior`	Junior LP token mint

Loaded market addresses

console.log("SY mint:", market.syMint.toBase58());
console.log("SY program:", market.syProgram.toBase58());
console.log("Senior LP mint:", market.mintLpSenior.toBase58());
console.log("Junior LP mint:", market.mintLpJunior.toBase58());
console.log("SY escrow:", market.tokenSyEscrow.toBase58());
console.log("Base mint:", market.mintBase.toBase58());

Getter	Returns	Description
`syMint`	`PublicKey`	SY token mint backing the market
`syProgram`	`PublicKey`	Linked SY program
`mintLpSenior`	`PublicKey`	Senior LP mint
`mintLpJunior`	`PublicKey`	Junior LP mint
`tokenSyEscrow`	`PublicKey`	Market SY escrow
`mintBase`	`PublicKey`	Underlying base asset mint exposed by the market flavor
`currentSyExchangeRate`	`number`	Current exchange rate from the loaded SY flavor

User LP accounts

import { TrancheSide } from "@exponent-labs/exponent-sdk/client/tranching";

const seniorLpAta = market.lpAta(TrancheSide.Senior, wallet.publicKey);
const juniorLpAta = market.lpAta(TrancheSide.Junior, wallet.publicKey);

console.log("Senior LP ATA:", seniorLpAta.toBase58());
console.log("Junior LP ATA:", juniorLpAta.toBase58());

Function	Description
`lpMint(trancheSide)`	Returns the LP mint for `Senior` or `Junior`
`lpAta(trancheSide, owner)`	Returns the owner’s associated token account for the selected LP mint

The wrapper deposit and withdraw methods create these associated token accounts idempotently through setupIxs.
