Creating A Client

import { Connection, PublicKey } from "@solana/web3.js"
import { CpAmm } from "@meteora-ag/cp-amm-sdk"

const connection = new Connection("https://api.mainnet-beta.solana.com")
const cpAmm = new CpAmm(connection)

const poolState = await cpAmm.fetchPoolState(new PublicKey("..."))

The client stores the connection-backed Anchor program and exposes read methods, quote methods, and unsigned transaction builders. The caller still sets the fee payer, recent blockhash, signs, simulates, and submits.

Core Types

The SDK exports many parameter and result aliases so app code can keep transaction-building code typed:

Common Workflows

Fetch Pool And Build A Quote

import BN from "bn.js"
import { CpAmm, SwapMode, getTokenProgram } from "@meteora-ag/cp-amm-sdk"

const cpAmm = new CpAmm(connection)
const poolState = await cpAmm.fetchPoolState(pool)

const quote = cpAmm.getQuote2({
  poolState,
  inputTokenMint: poolState.tokenAMint,
  amountIn: new BN(1_000_000),
  slippage: 50, // 0.5%, in basis points
  swapMode: SwapMode.ExactIn,
  currentPoint,
  tokenADecimal: 6,
  tokenBDecimal: 6,
  hasReferral: false,
})

getQuote2 is the preferred quote path for new integrations because it supports exact-in, partial-fill, and exact-out behavior.

Build A Swap Transaction

const tx = await cpAmm.swap2({
  payer: user,
  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: new BN(1_000_000),
  minimumAmountOut: quote.minimumAmountOut!,
})

Rate-limiter pools require the instructions sysvar account on low-level swap builders. The TypeScript SDK detects existing rate-limiter pools in swap and swap2 when it has poolState; pass poolState to avoid an extra RPC read and to keep account planning explicit.

Decode Pool Fees

const poolFees = await cpAmm.fetchPoolFees(pool)

if (poolFees) {
  // `poolFees` is one of the pod-aligned scheduler layouts.
}

Use the pod-aligned decoders for pool-state bytes and Borsh decoders for event bytes.

Error Classes

The SDK exports typed errors that validation, quote, and math helpers may throw:

Error	Typical trigger
`DepositTokenNotAcceptedError`	Deposit token does not match the position or pool side expected by the quote.
`InvalidFeeError`	Fee params are malformed or out of range.
`ExceedMaxFeeBpsError`	Fee bps exceeds the pool-version maximum.
`InvalidActivationTypeError`	Activation type is not a supported enum value.
`InvalidPriceRangeError`	Square-root price bounds are invalid for the collect-fee mode.
`InvalidCollectFeeModeError`	Collect-fee mode is not supported by the requested flow.
`InvalidCompoundingFeeBpsError`	`compoundingFeeBps` is outside `0` to `10_000` for compounding, or it is not `0` for another collect fee mode.
`InvalidScaledUiAmountMultiplierError`	A Scaled UI Amount multiplier is `0`, negative, or not finite.
`InvalidFeeTimeSchedulerError`	Time-scheduler fee params are invalid.
`InvalidFeeMarketCapSchedulerError`	Market-cap scheduler fee params are invalid.
`InvalidFeeRateLimiterError`	Rate-limiter params are invalid.
`InvalidDynamicFeeParametersError`	Dynamic-fee params are invalid.
`InvalidMinimumLiquidityError`	Initial liquidity is below the minimum, especially in compounding pool creation.
`AmountIsZeroError`	Required amount or liquidity delta is zero.
`InvalidBaseFeeModeError`	Base-fee mode is unsupported for the selected helper.
`DeprecatedBaseFeeModeError`	`getBaseFeeParams`, `validatePoolFees`, `createPool`, `createCustomPool`, or `createCustomPoolWithDynamicConfig` received `BaseFeeMode.RateLimiter`.
`InvalidPoolVersionError`	Pool version is unsupported by a helper.
`MathOverflowError`	Integer math overflows or cannot be represented.
`InsufficientLiquidityError`	Swap or withdraw math requests more liquidity than available.
`SwapDisabledError`	Pool is disabled or not activated for swapping.
`InvalidInputError`	General invalid input error.
`PriceRangeViolationError`	Quote or liquidity math would move outside allowed price bounds.
`SameTokenMintsError`	Pool creation or validation received identical mints.
`InvalidParametersError`	General invalid parameter error.
`InvalidSplitPositionParametersError`	Split position params are invalid.
`InvalidVestingInfoError`	Vesting data is invalid for lock or unlock flow.
`InvalidRewardIndexError`	Reward index is outside the supported range.
`InvalidRewardDurationError`	Reward duration is below or above allowed bounds.

Notes

Topic	What to remember
Token order	Pool PDAs sort mints, but transaction params still need the pool’s `tokenAMint` and `tokenBMint` fields.
Compounding mode	`CollectFeeMode.Compounding` uses full-range constant-product liquidity. `compoundingFeeBps` of `0` sets `compoundingFee` to `0` and leaves the trading fee in `claimingFee`.
Rate limiter	Existing rate-limiter pools still require the instructions sysvar remaining account on low-level swap builders when the limiter is active. The SDK handles this when it can identify the pool mode. New configs and new pools cannot use `RateLimiter`.
Layout version	V1 pools track `tokenAAmount` and `tokenBAmount`. Use current SDK quote paths for compounding pools.
Swap events	Prefer `EvtSwap2` for swap indexing. Older swap events were deprecated and removed from newer program versions.
Position NFTs	Pass the token account that currently holds the position NFT. A delegate signs with the same `owner` SDK field. `getPositionsByDelegate` skips `delegatePermission = 0`.
Wrapped SOL	Transaction builders add wrap and unwrap instructions for native SOL paths, but your signing flow still needs enough SOL for rent, transaction fees, and wrapped input amounts.
Token-2022 fees	Pass mint and epoch data into quote helpers when a Token-2022 transfer-fee mint is involved so quoted amounts include transfer fees.
