- 1.Install dependencies
npm i @mercurial-finance/farming-sdk @project-serum/anchor @solana/web3.js @solana/spl-token @solana/spl-token-registry
- 2.Initialize PoolFarmImpl instance
import { PoolFarmImpl } from "@mercurial-finance/farming-sdk";
import { Wallet, AnchorProvider } from "@coral-xyz/anchor";
import { Connection, PublicKey, Keypair } from "@solana/web3.js";
// Connection, Wallet, and AnchorProvider to interact with the network
const mainnetConnection = new Connection("https://api.mainnet-beta.solana.com");
const mockWallet = new Wallet(new Keypair());
const provider = new AnchorProvider(mainnetConnection, mockWallet, {
commitment: "confirmed",
});
// Alternatively, to use Solana Wallet Adapter
const USDC_acUSDC_POOL = new PublicKey(
"6ZLKLjMd2KzH7PPHCXUPgbMAtdTT37VgTtdeXWLoJppr"
); // Pool Address can get from https://docs.meteora.ag/dynamic-pools-integration/dynamic-pool-api/pool-info
const farmingPools = await PoolFarmImpl.getFarmAddressesByPoolAddress(
USDC_acUSDC_POOL
);
// farmingPools is an array (A pool can have multiple farms)
const farmingPool = farmingPools[0];
const farm = await PoolFarmImpl.create(
mainnetConnection,
farmingPool.farmAddress
);
- 3.To interact with the PoolFarmImpl
- Stake
// https://station.jup.ag/blog/jupiter-token-list-api#endpoints
const tokenList = await fetch('https://token.jup.ag/all').then(res => res.json());
const USDC = tokenList.find(token => token.address === <USDC_ADDRESS>);
const USDT = tokenList.find(token => token.address === <USDT_ADDRESS>);
// Get pool lp balance from `@mercurial-finance/dynamic-amm-sdk` package
const pool = await AmmImpl.create(connection, MAINNET_POOL.USDC_USDT, USDC, USDT);
const lpBalance = await pool.getUserBalance(mockWallet.publicKey);
const stakeTx = await farm.deposit(mockWallet.publicKey, lpBalance); // Web3 Transaction Object
const stakeResult = await provider.sendAndConfirm(stakeTx); // Transaction hash
- Check stake balance
const farmBalance = await farm.getUserBalance(mockWallet.publicKey);
- Claim
const claimTx = await farm.claim(mockWallet.publicKey);
const claimResult = await provider.sendAndConfirm(claimTx); // Transaction hash
- Unstake
const unStakeTx = await farm.withdraw(mockWallet.publicKey, farmBalance); // Web3 Transaction Object
const unstakeResult = await provider.sendAndConfirm(depositTx); // Transaction hash
