DAMM v2 TS SDK Examples - Meteora Documentation

These examples are based on the local damm-v2-sdk examples and tests. They focus on transaction construction patterns. For the full method catalog, see the SDK Reference.

Setup

import {
  ActivationType,
  BaseFeeMode,
  CollectFeeMode,
  CpAmm,
  MAX_SQRT_PRICE,
  MIN_SQRT_PRICE,
  SwapMode,
  derivePositionAddress,
  derivePositionNftAccount,
  getBaseFeeParams,
  getCurrentPoint,
  getDynamicFeeParams,
  getSqrtPriceFromPrice,
  getTokenProgram,
  type PoolFeesParams,
} from "@meteora-ag/cp-amm-sdk";
import {
  Connection,
  Keypair,
  PublicKey,
  sendAndConfirmTransaction,
} from "@solana/web3.js";
import {
  TOKEN_2022_PROGRAM_ID,
  TOKEN_PROGRAM_ID,
  getMint,
} from "@solana/spl-token";
import BN from "bn.js";

const connection = new Connection(process.env.RPC_URL!, "confirmed");
const cpAmm = new CpAmm(connection);

// Replace this with your server-side signer or wallet signing flow.
const user = Keypair.generate();
const pool = new PublicKey("...");

Use devnet while testing. The DAMM v2 program ID is the same for devnet and mainnet:

// cpamdpZCGKUy5JxQXB4dcpGPiikHawvSWAd6mEn1sGG

Fetch Pool And User Positions

const poolState = await cpAmm.fetchPoolState(pool);

const userPositions = await cpAmm.getUserPositionByPool(
  pool,
  user.publicKey,
);

const largestPosition = userPositions[0];

console.log({
  tokenA: poolState.tokenAMint.toBase58(),
  tokenB: poolState.tokenBMint.toBase58(),
  position: largestPosition?.position.toBase58(),
});

Use getPositionsByUser(user) when you need a wallet-level position view across all pools.

Quote And Swap

The recommended swap flow is:

Fetch the pool state.
Resolve the current activation point.
Quote with getQuote2.
Build the swap with swap2.
Simulate, sign, and send.

const poolState = await cpAmm.fetchPoolState(pool);
const currentPoint = await getCurrentPoint(
  connection,
  poolState.activationType as ActivationType,
);

const amountIn = new BN(1_000_000);

const quote = cpAmm.getQuote2({
  inputTokenMint: poolState.tokenAMint,
  poolState,
  currentPoint,
  amountIn,
  slippage: 0.5,
  swapMode: SwapMode.ExactIn,
  tokenADecimal: 6,
  tokenBDecimal: 6,
  hasReferral: false,
});

const tx = await cpAmm.swap2({
  payer: user.publicKey,
  pool,
  inputTokenMint: poolState.tokenAMint,
  outputTokenMint: poolState.tokenBMint,
  tokenAMint: poolState.tokenAMint,
  tokenBMint: poolState.tokenBMint,
  tokenAVault: poolState.tokenAVault,
  tokenBVault: poolState.tokenBVault,
  tokenAProgram: getTokenProgram(poolState.tokenAFlag),
  tokenBProgram: getTokenProgram(poolState.tokenBFlag),
  referralTokenAccount: null,
  poolState,
  swapMode: SwapMode.ExactIn,
  amountIn,
  minimumAmountOut: quote.minimumAmountOut!,
});

tx.feePayer = user.publicKey;
tx.recentBlockhash = (await connection.getLatestBlockhash()).blockhash;
console.log(await connection.simulateTransaction(tx));

const signature = await sendAndConfirmTransaction(connection, tx, [user]);
console.log("Swap signature", signature);

Use SwapMode.PartialFill when the swap may consume less than the requested input. Use SwapMode.ExactOut with maximumAmountIn when the output amount is fixed.

Create A Position And Add Liquidity

createPositionAndAddLiquidity creates the position NFT and adds liquidity in one transaction.

const poolState = await cpAmm.fetchPoolState(pool);
const positionNft = Keypair.generate();
const position = derivePositionAddress(positionNft.publicKey);

const maxAmountTokenA = new BN(1_000_000);
const maxAmountTokenB = new BN(1_000_000);

const liquidityDelta = cpAmm.getLiquidityDelta({
  maxAmountTokenA,
  maxAmountTokenB,
  sqrtPrice: poolState.sqrtPrice,
  sqrtMinPrice: poolState.sqrtMinPrice,
  sqrtMaxPrice: poolState.sqrtMaxPrice,
  collectFeeMode: poolState.collectFeeMode,
  tokenAAmount: poolState.tokenAAmount,
  tokenBAmount: poolState.tokenBAmount,
  liquidity: poolState.liquidity,
});

const tx = await cpAmm.createPositionAndAddLiquidity({
  owner: user.publicKey,
  pool,
  positionNft: positionNft.publicKey,
  liquidityDelta,
  maxAmountTokenA,
  maxAmountTokenB,
  tokenAAmountThreshold: maxAmountTokenA,
  tokenBAmountThreshold: maxAmountTokenB,
  tokenAMint: poolState.tokenAMint,
  tokenBMint: poolState.tokenBMint,
  tokenAProgram: getTokenProgram(poolState.tokenAFlag),
  tokenBProgram: getTokenProgram(poolState.tokenBFlag),
});

await sendAndConfirmTransaction(connection, tx, [user, positionNft]);

console.log("Created position", position.toBase58());

For compounding pools, include tokenAAmount, tokenBAmount, and liquidity when calculating liquidity so the quote uses the current pool reserves.

Add Liquidity To An Existing Position

Use getDepositQuote before building the transaction. The quote returns the liquidity delta and the counterpart token amount.

const poolState = await cpAmm.fetchPoolState(pool);
const positionNftMint = new PublicKey("...");
const position = derivePositionAddress(positionNftMint);
const positionNftAccount = derivePositionNftAccount(positionNftMint);

const inAmount = new BN(1_000_000);
const depositQuote = cpAmm.getDepositQuote({
  inAmount,
  isTokenA: true,
  sqrtPrice: poolState.sqrtPrice,
  minSqrtPrice: poolState.sqrtMinPrice,
  maxSqrtPrice: poolState.sqrtMaxPrice,
  collectFeeMode: poolState.collectFeeMode,
  tokenAAmount: poolState.tokenAAmount,
  tokenBAmount: poolState.tokenBAmount,
  liquidity: poolState.liquidity,
});

const tx = await cpAmm.addLiquidity({
  owner: user.publicKey,
  pool,
  position,
  positionNftAccount,
  liquidityDelta: depositQuote.liquidityDelta,
  maxAmountTokenA: depositQuote.actualInputAmount,
  maxAmountTokenB: depositQuote.outputAmount,
  tokenAAmountThreshold: depositQuote.actualInputAmount,
  tokenBAmountThreshold: depositQuote.outputAmount,
  tokenAMint: poolState.tokenAMint,
  tokenBMint: poolState.tokenBMint,
  tokenAVault: poolState.tokenAVault,
  tokenBVault: poolState.tokenBVault,
  tokenAProgram: getTokenProgram(poolState.tokenAFlag),
  tokenBProgram: getTokenProgram(poolState.tokenBFlag),
});

await sendAndConfirmTransaction(connection, tx, [user]);

Remove Liquidity And Close A Position

removeAllLiquidityAndClosePosition combines fee claim, full liquidity removal, and position close. It will reject locked positions, so load vesting accounts and the current point first.

const poolState = await cpAmm.fetchPoolState(pool);
const position = new PublicKey("...");
const positionNftAccount = new PublicKey("...");
const positionState = await cpAmm.fetchPositionState(position);
const currentPoint = await getCurrentPoint(
  connection,
  poolState.activationType as ActivationType,
);

const vestings = (await cpAmm.getAllVestingsByPosition(position)).map(
  ({ publicKey, account }) => ({
    account: publicKey,
    vestingState: account,
  }),
);

const tx = await cpAmm.removeAllLiquidityAndClosePosition({
  owner: user.publicKey,
  position,
  positionNftAccount,
  poolState,
  positionState,
  tokenAAmountThreshold: new BN(0),
  tokenBAmountThreshold: new BN(0),
  vestings,
  currentPoint,
});

await sendAndConfirmTransaction(connection, tx, [user]);

Use removeLiquidity when you only want to remove a specific liquidity delta and keep the position open.

Claim Position Fees

claimPositionFee2 is the preferred fee claim helper for new integrations.

const poolState = await cpAmm.fetchPoolState(pool);
const userPositions = await cpAmm.getUserPositionByPool(pool, user.publicKey);
const { position, positionNftAccount } = userPositions[0];

const tx = await cpAmm.claimPositionFee2({
  receiver: user.publicKey,
  feePayer: user.publicKey,
  owner: user.publicKey,
  pool,
  position,
  positionNftAccount,
  tokenAMint: poolState.tokenAMint,
  tokenBMint: poolState.tokenBMint,
  tokenAVault: poolState.tokenAVault,
  tokenBVault: poolState.tokenBVault,
  tokenAProgram: getTokenProgram(poolState.tokenAFlag),
  tokenBProgram: getTokenProgram(poolState.tokenBFlag),
});

await sendAndConfirmTransaction(connection, tx, [user]);

Lock Liquidity

Use permanentLockPosition for irreversible locks and lockPosition for vesting schedules.

const positionNftMint = new PublicKey("...");
const position = derivePositionAddress(positionNftMint);
const positionNftAccount = derivePositionNftAccount(positionNftMint);
const unlockedLiquidity = new BN("1000000000000");

const permanentLockTx = await cpAmm.permanentLockPosition({
  owner: user.publicKey,
  pool,
  position,
  positionNftAccount,
  unlockedLiquidity,
});

await sendAndConfirmTransaction(connection, permanentLockTx, [user]);

For scheduled vesting, create a vesting account signer and pass the cliff and period settings:

const vestingAccount = Keypair.generate();

const vestingTx = await cpAmm.lockPosition({
  owner: user.publicKey,
  payer: user.publicKey,
  pool,
  position,
  positionNftAccount,
  cliffPoint: null,
  periodFrequency: new BN(24 * 60 * 60),
  cliffUnlockLiquidity: new BN(0),
  liquidityPerPeriod: new BN("250000000000"),
  numberOfPeriod: 4,
  vestingAccount: vestingAccount.publicKey,
});

await sendAndConfirmTransaction(connection, vestingTx, [user, vestingAccount]);

Initialize And Claim Rewards

initializeAndFundReward creates a reward slot and funds it in one transaction.

const rewardMint = new PublicKey("...");
const rewardIndex = 0;

const initRewardTx = await cpAmm.initializeAndFundReward({
  rewardIndex,
  rewardDuration: new BN(24 * 60 * 60),
  pool,
  creator: user.publicKey,
  payer: user.publicKey,
  rewardMint,
  carryForward: false,
  amount: new BN(1_000_000_000),
  rewardMintProgram: TOKEN_PROGRAM_ID,
});

await sendAndConfirmTransaction(connection, initRewardTx, [user]);

Claim rewards by loading the current pool and position state:

const position = new PublicKey("...");
const positionNftAccount = new PublicKey("...");
const poolState = await cpAmm.fetchPoolState(pool);
const positionState = await cpAmm.fetchPositionState(position);

const claimRewardTx = await cpAmm.claimReward({
  user: user.publicKey,
  position,
  poolState,
  positionState,
  positionNftAccount,
  rewardIndex: 0,
  isSkipReward: false,
  feePayer: user.publicKey,
});

await sendAndConfirmTransaction(connection, claimRewardTx, [user]);

Use initializeReward plus fundReward when initialization and funding should be separate admin actions.

Create A Customizable Pool

Customizable pools let the creator set fee behavior, activation behavior, and whether initial liquidity should be locked.

const tokenAMint = new PublicKey("...");
const tokenBMint = new PublicKey("...");
const tokenADecimals = 6;
const tokenBDecimals = 6;

const tokenAAmount = new BN(1_000_000).mul(
  new BN(10).pow(new BN(tokenADecimals)),
);
const tokenBAmount = new BN(1_000_000).mul(
  new BN(10).pow(new BN(tokenBDecimals)),
);
const initSqrtPrice = getSqrtPriceFromPrice("1", tokenADecimals, tokenBDecimals);

const liquidityDelta = cpAmm.getLiquidityDelta({
  maxAmountTokenA: tokenAAmount,
  maxAmountTokenB: tokenBAmount,
  sqrtPrice: initSqrtPrice,
  sqrtMinPrice: MIN_SQRT_PRICE,
  sqrtMaxPrice: MAX_SQRT_PRICE,
  collectFeeMode: CollectFeeMode.BothToken,
});

const baseFee = getBaseFeeParams(
  {
    baseFeeMode: BaseFeeMode.FeeTimeSchedulerExponential,
    feeTimeSchedulerParam: {
      startingFeeBps: 5000,
      endingFeeBps: 25,
      numberOfPeriod: 60,
      totalDuration: 3600,
    },
  },
  tokenBDecimals,
  ActivationType.Timestamp,
);

const poolFees: PoolFeesParams = {
  baseFee,
  compoundingFeeBps: 0,
  padding: 0,
  dynamicFee: getDynamicFeeParams(25),
};

const positionNft = Keypair.generate();

const {
  tx,
  pool: newPool,
  position: initialPosition,
} = await cpAmm.createCustomPool({
  payer: user.publicKey,
  creator: user.publicKey,
  positionNft: positionNft.publicKey,
  tokenAMint,
  tokenBMint,
  tokenAAmount,
  tokenBAmount,
  sqrtMinPrice: MIN_SQRT_PRICE,
  sqrtMaxPrice: MAX_SQRT_PRICE,
  liquidityDelta,
  initSqrtPrice,
  poolFees,
  hasAlphaVault: false,
  activationType: ActivationType.Timestamp,
  collectFeeMode: CollectFeeMode.BothToken,
  activationPoint: null,
  tokenAProgram: TOKEN_PROGRAM_ID,
  tokenBProgram: TOKEN_PROGRAM_ID,
  isLockLiquidity: false,
});

await sendAndConfirmTransaction(connection, tx, [user, positionNft]);

console.log({
  pool: newPool.toBase58(),
  position: initialPosition.toBase58(),
});

Use createPool instead when you are creating against an existing DAMM v2 config account. Use createCustomPoolWithDynamicConfig when your flow needs to create through a dynamic config account.

Token-2022 Transfer Fee Inputs

For Token-2022 transfer-fee mints, pass mint and epoch data into quote helpers so the SDK can account for transfer fees.

async function getTransferFeeInfo(mint: PublicKey, tokenProgram: PublicKey) {
  if (!tokenProgram.equals(TOKEN_2022_PROGRAM_ID)) {
    return undefined;
  }

  const [mintAccount, epochInfo] = await Promise.all([
    getMint(connection, mint, connection.commitment, tokenProgram),
    connection.getEpochInfo(),
  ]);

  return {
    mint: mintAccount,
    currentEpoch: epochInfo.epoch,
  };
}

const poolState = await cpAmm.fetchPoolState(pool);
const tokenAProgram = getTokenProgram(poolState.tokenAFlag);
const tokenBProgram = getTokenProgram(poolState.tokenBFlag);

const quote = cpAmm.getQuote2({
  inputTokenMint: poolState.tokenAMint,
  poolState,
  currentPoint: await getCurrentPoint(
    connection,
    poolState.activationType as ActivationType,
  ),
  amountIn: new BN(1_000_000),
  slippage: 0.5,
  swapMode: SwapMode.ExactIn,
  tokenADecimal: 6,
  tokenBDecimal: 6,
  hasReferral: false,
  inputTokenInfo: await getTransferFeeInfo(poolState.tokenAMint, tokenAProgram),
  outputTokenInfo: await getTransferFeeInfo(poolState.tokenBMint, tokenBProgram),
});

console.log(quote.minimumAmountOut?.toString());
