The MarketThree class exposes getter properties for reading onchain market state. After loading a market, you can access token mints, balances, configuration, and time-related parameters directly.
Usage
import { MarketThree, LOCAL_ENV } from "@exponent-labs/exponent-sdk";
import { Connection, PublicKey } from "@solana/web3.js";
const connection = new Connection("https://api.mainnet-beta.solana.com");
const market = await MarketThree.load(LOCAL_ENV, connection, marketAddress);
// Token mints
console.log("PT Mint:", market.mintPt.toBase58());
console.log("SY Mint:", market.mintSy.toBase58());
console.log("YT Mint:", market.mintYt.toBase58());
// Market balances
console.log("PT Balance:", market.ptBalance);
console.log("SY Balance:", market.syBalance);
console.log("LP Balance:", market.lpBalance);
// Time and rate
console.log("SY Exchange Rate:", market.currentSyExchangeRate);
console.log("Seconds Remaining:", market.secondsRemaining);
// Status
console.log("Status Flags:", market.statusFlags);
Getter Properties
| Property | Type | Description |
|---|
mintPt | PublicKey | PT token mint address |
mintSy | PublicKey | SY token mint address |
mintYt | PublicKey | YT token mint address |
ptBalance | bigint | PT tokens held in the market |
syBalance | bigint | SY tokens held in the market |
lpBalance | bigint | Total LP token supply |
currentSyExchangeRate | number | Current SY exchange rate from the underlying yield source |
secondsRemaining | number | Seconds until market expiration |
statusFlags | number | Bitmask of enabled operations |
Nested State Properties
For deeper state access, use market.state:
// Financial parameters
const expiration = market.state.financials.expirationTs;
// Configuration
const tickSpace = market.state.configurationOptions.tickSpace;
const feeRateRoot = market.state.configurationOptions.lnFeeRateRoot;
const treasuryFeeBps = market.state.configurationOptions.treasuryFeeBps;
Call await market.reload() to refresh the market state from onchain data before reading properties.
