CLMM code demos

Version banner. All TypeScript demos target @raydium-io/raydium-sdk-v2@0.2.64-alpha; they were last executed against 0.2.42-alpha (2026-04) and their call signatures re-checked against the 0.2.64-alpha source on 2026-09-09, against Solana mainnet-beta. The Rust CPI skeleton at the end targets raydium-clmm on the chore/upgrade-anchor branch, Anchor 1.0.2, the same pin as the CPMM page, so the two can live in one crate. master still pins 0.32.1. Program IDs come from reference/program-addresses via the SDK.

Setup

npm install @raydium-io/raydium-sdk-v2 @solana/web3.js @solana/spl-token bn.js decimal.js

Every demo on this page mirrors a file in raydium-sdk-V2-demo/src/clmm; the GitHub link sits next to each section. Bootstrap follows the demo repo’s config.ts.template (source) — disableFeatureCheck: true is the recommended setting for any non-trivial integration:

import { Connection, Keypair, clusterApiUrl } from "@solana/web3.js";
import { Raydium, TxVersion } from "@raydium-io/raydium-sdk-v2";
import fs from "node:fs";

const connection = new Connection(process.env.RPC_URL ?? clusterApiUrl("mainnet-beta"));
const owner = Keypair.fromSecretKey(
  new Uint8Array(JSON.parse(fs.readFileSync(process.env.KEYPAIR!, "utf8"))),
);
const raydium = await Raydium.load({
  owner,
  connection,
  cluster: "mainnet",
  disableFeatureCheck: true,
  blockhashCommitment: "finalized",
});
export const txVersion = TxVersion.V0;

Create a CLMM pool

Source: src/clmm/createPool.ts

import { PublicKey } from "@solana/web3.js";
import { CLMM_PROGRAM_ID } from "@raydium-io/raydium-sdk-v2";
import BN from "bn.js";
import Decimal from "decimal.js";

const mintA = await raydium.token.getTokenInfo(
  new PublicKey("So11111111111111111111111111111111111111112"));   // wSOL
const mintB = await raydium.token.getTokenInfo(
  new PublicKey("EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v"));   // USDC

// getClmmConfigs() returns ApiClmmConfigInfo (id is a string). createPool wants
// ClmmConfigInfo, which needs a PublicKey id plus fundOwner/description — convert:
const clmmConfigs = await raydium.api.getClmmConfigs();
const picked = clmmConfigs.find((c) => c.index === 1)!;        // 0.05% tier
const ammConfig = { ...picked, id: new PublicKey(picked.id), fundOwner: "", description: "" };

const initialPrice = new Decimal(160);        // 160 USDC per SOL
const { execute, extInfo } = await raydium.clmm.createPool({
  programId: CLMM_PROGRAM_ID,
  mint1:     mintA,
  mint2:     mintB,
  ammConfig,
  initialPrice,
  txVersion: TxVersion.V0,   // no `startTime` — CreateConcentratedPool has no such field
});

const { txId } = await execute({ sendAndConfirm: true });
console.log("Pool:", extInfo.address.id, "tx:", txId);   // already a base58 string

The SDK:

Sorts mint1/mint2 by byte order before derivation.
Computes sqrt_price_x64 = floor(sqrt(initialPrice × 10^(dB−dA)) × 2^64).
Creates the observation and tick_array_bitmap_extension accounts.
Pays the pool-creation fee defined by ammConfig.

Open a position in a chosen range

Source: src/clmm/createPosition.ts

import { PoolUtils, TickUtil } from "@raydium-io/raydium-sdk-v2";

const POOL_ID = "<POOL_ID>";   // base58 string
// note: CLMM's getPoolInfoFromRpc returns `rpcPoolInfo`, not `rpcData` (CPMM's does)
const { poolInfo, poolKeys, rpcPoolInfo } = await raydium.clmm.getPoolInfoFromRpc(POOL_ID);

// Choose a price range. Here: ±10% of current.
const currentPrice = new Decimal(poolInfo.price);
const lowerPrice   = currentPrice.mul(0.9);
const upperPrice   = currentPrice.mul(1.1);

// Snap to valid ticks for this pool's tick_spacing.
// The class is TickUtil (singular), and it takes decimals + tickSpacing, not poolInfo.
const { tick: tickLower } = TickUtil.getPriceAndTick({
  price: lowerPrice,
  mintADecimals: poolInfo.mintA.decimals,
  mintBDecimals: poolInfo.mintB.decimals,
  zeroForOne: true,
  tickSpacing: poolInfo.config.tickSpacing,
});
const { tick: tickUpper } = TickUtil.getPriceAndTick({
  price: upperPrice,
  mintADecimals: poolInfo.mintA.decimals,
  mintBDecimals: poolInfo.mintB.decimals,
  zeroForOne: true,
  tickSpacing: poolInfo.config.tickSpacing,
});

// How much of each token to deposit.
const inputAmount = new BN(10_000_000);  // 0.01 SOL

// getLiquidityAmountOutFromAmountIn is async — await it.
const res = await PoolUtils.getLiquidityAmountOutFromAmountIn({
  poolInfo,
  slippage: 0.01,
  inputA: true,
  tickUpper,
  tickLower,
  amount: inputAmount,
  add: true,
  amountHasFee: true,
  epochInfo: await raydium.fetchEpochInfo(),
});

const { execute } = await raydium.clmm.openPositionFromBase({
  poolInfo,
  poolKeys,
  tickUpper,
  tickLower,
  base: "MintA",
  ownerInfo: { useSOLBalance: true },
  baseAmount: inputAmount,
  otherAmountMax: res.amountSlippageB.amount,
  txVersion: TxVersion.V0,
});

const { txId } = await execute({ sendAndConfirm: true });
console.log("Position opened, tx:", txId);

The SDK computes which tick arrays the range touches and passes them as accounts. It does not need to bundle any init instruction — there is no init-tick-array instruction; OpenPosition* allocates a missing tick array itself, at the payer’s expense.

Increase liquidity on an existing position

Source: src/clmm/increaseLiquidity.ts

const positionNftMint = new PublicKey("<POSITION_NFT_MINT>");

// There is no getPositionInfo — enumerate the wallet's positions and pick one.
const allPositions = await raydium.clmm.getOwnerPositionInfo({
  programId: poolInfo.programId,
});
const positionAccount = allPositions.find((p) => p.nftMint.equals(positionNftMint));
if (!positionAccount) throw new Error("position not found for this wallet");

const { execute } = await raydium.clmm.increasePositionFromBase({
  poolInfo,
  ownerPosition: positionAccount,
  ownerInfo: { useSOLBalance: true },   // required
  base: "MintA",
  baseAmount: new BN(5_000_000),
  otherAmountMax: new BN(1_000_000_000),
  txVersion: TxVersion.V0,              // no poolKeys member on this call
});

await execute({ sendAndConfirm: true });

Decrease liquidity (and collect fees at the same time)

Source: src/clmm/decreaseLiquidity.ts and src/clmm/closePosition.ts

const { execute } = await raydium.clmm.decreaseLiquidity({
  poolInfo,
  poolKeys,
  ownerPosition: positionAccount,
  ownerInfo: {                       // required; closePosition lives in here
    useSOLBalance: true,
    closePosition: false,
  },
  liquidity: positionAccount.liquidity.divn(2),   // halve
  amountMinA: new BN(0),
  amountMinB: new BN(0),
  txVersion: TxVersion.V0,
});

await execute({ sendAndConfirm: true });

To collect fees and rewards only, call decreaseLiquidity with liquidity = new BN(0). The instruction’s side-effect is settling token_fees_owed_{0,1} and reward_amount_owed and transferring them out — this is the only way to collect either. To close the position entirely after zeroing liquidity and fees, pass ownerInfo: { closePosition: true } on the final decreaseLiquidity call. The SDK appends ClosePosition and burns the NFT.

Restricted-issuer positions require a compatible close builder. These positions have a frozen NFT token account. ClosePosition must append the position’s pool ID as the first remaining account so CLMM can thaw the account before burning it. The program-source branch does not include an SDK change. Confirm that your SDK release explicitly supports the frozen close path before enabling restricted-issuer position creation.

For a direct Anchor client, keep the declared accounts unchanged and append the pool:

// CLMM program: see reference/program-addresses; source ecb1577;
// Solana mainnet-beta; last verified 2026-08-13.
await program.methods
  .closePosition()
  .accounts({
    nftOwner,
    positionNftMint,
    positionNftAccount,
    personalPosition,
    systemProgram: SystemProgram.programId,
    tokenProgram: positionNftTokenProgram,
  })
  .remainingAccounts([
    { pubkey: poolId, isWritable: false, isSigner: false },
  ])
  .rpc();

You may pass poolId on every close. CLMM reads it only when positionNftAccount is frozen, which keeps one client path compatible with old and new positions.

Collect reward(s)

Source: src/clmm/harvestAllRewards.ts

import { CLMM_PROGRAM_ID } from "@raydium-io/raydium-sdk-v2";

const { execute } = await raydium.clmm.harvestAllRewards({
  ownerInfo: { useSOLBalance: true },
  allPoolInfo: { [poolInfo.id]: poolInfo },
  allPositions: { [poolInfo.id]: [positionAccount] },
  programId: CLMM_PROGRAM_ID,
  txVersion: TxVersion.V0,
});

// harvestAllRewards is a MULTI-transaction builder: `sequentially` is required
// and the result is `txIds`, not `txId`.
const { txIds } = await execute({ sequentially: true });

harvestAllRewards walks every position on every pool passed in, batches the zero-liquidity DecreaseLiquidity calls that settle fees and rewards (plus any UpdateRewardInfos), and splits them across transactions if needed.

Swap

Source: src/clmm/swap.ts

This mirrors `src/clmm/swap.ts`, which simulates with `swapInternal` rather than
`PoolUtils.computeAmountOutFormat`.

```ts
import {
  swapInternal,
  getPdaExBitmapAccount,
  TickArrayBitmapExtensionLayout,
  CLMM_PROGRAM_ID,
} from "@raydium-io/raydium-sdk-v2";

const amountIn   = new BN(10_000_000);
const zeroForOne = true;             // swap A (SOL) → B (USDC)

const poolIdPub = new PublicKey(poolInfo.id);
const { rpcData, tickArrays, configInfo } =
  await raydium.clmm.getSwapPoolInfo(poolInfo.id, zeroForOne);

const exBitmap = getPdaExBitmapAccount(CLMM_PROGRAM_ID, poolIdPub).publicKey;
const exBitmapInfo = await raydium.connection.getAccountInfo(exBitmap);

const simulation = swapInternal({
  programId: CLMM_PROGRAM_ID,
  poolId: poolIdPub,
  poolInfo: rpcData,
  tickArrays,
  configInfo,
  tickarrayBitmapExtension: TickArrayBitmapExtensionLayout.decode(exBitmapInfo!.data),
  amountSpecified: amountIn,
  sqrtPriceLimitX64: new BN(0),
  zeroForOne,
  isBaseInput: true,               // false for exact-output
  blockTimestamp: Math.floor(Date.now() / 1000),
  includeExtraTickArrays: true,
});

const { execute } = await raydium.clmm.swap({
  poolInfo,
  poolKeys,
  inputMint: poolInfo.mintA.address,
  amountIn,
  amountOutMin: simulation.amountCalculated,
  observationId: rpcData.observationId,
  ownerInfo: { useSOLBalance: true },   // required
  remainingAccounts: simulation.accounts,
  txVersion: TxVersion.V0,
});

await execute({ sendAndConfirm: true });

The simulation walks the tick map off-chain with the same logic as the on-chain program and returns the amount out (amountCalculated) plus the exact account list the swap will touch (accounts). Always pass the remainingAccounts the simulation returns: too few and the swap reverts mid-walk with NotEnoughTickArrayAccount; stale ones just waste compute.

PoolUtils.computeAmountOutFormat still exists, but it needs a ComputeClmmPoolInfo (the computePoolInfo from getPoolInfoFromRpc, not an API pool object) plus two more required arguments — tickarrayBitmapExtension and blockTimestamp — and there is no raydium.clmm.fetchTickArrays method (fetchTickArrays is a free function; the module-level helpers are PoolUtils.fetchMultiplePoolTickArrays and the tickData / tickArrays returned by getPoolInfoFromRpc).

Create a customizable CLMM pool

createCustomizablePool is the entry point that exposes the dynamic-fee and single-sided-fee toggles at pool-creation time. It takes createPool’s shape plus two additions:

import { CLMM_PROGRAM_ID, CollectFeeOn } from "@raydium-io/raydium-sdk-v2";

const dynamicFeeConfigs = await raydium.api.getClmmDynamicConfigs();    // GET /main/clmm-dynamic-config
const dynamicFeeConfig  = dynamicFeeConfigs.find((c) => c.index === 0); // pick a calibration tier

const { execute, extInfo } = await raydium.clmm.createCustomizablePool({
  programId: CLMM_PROGRAM_ID,
  mint1:     mintA,
  mint2:     mintB,
  ammConfig,
  initialPrice,
  // The two additions:
  collectFeeOn:      CollectFeeOn.TokenOnlyB,   // FromInput | TokenOnlyA | TokenOnlyB
  dynamicFeeConfig:  new PublicKey(dynamicFeeConfig!.id),
  txVersion: TxVersion.V0,
});

await execute({ sendAndConfirm: true });
console.log("Customizable pool:", extInfo.address.id);   // base58 string

There is no enableDynamicFee and no dynamicFeeConfigId parameter, and no startTime. Supplying dynamicFeeConfig is what enables dynamic fees — omit it and you get a static-fee pool, with no error. Note also that the SDK enum members are TokenOnlyA / TokenOnlyB, whereas the on-chain Rust enum spells them Token0Only / Token1Only; the numeric values match (FromInput = 0).

createPool continues to work for the default-fee, no-dynamic-fee path. Use createCustomizablePool whenever you need either knob. See products/clmm/instructions for the on-chain account list.

Limit orders

A limit order parks user input at a single tick and is filled FIFO when a swap crosses that tick. Outputs are pushed to the owner’s ATA at settle time; the owner does not need to be online to be filled.

Open a limit order

There is no per-pool limit-order config account and no `getClmmLimitOrderConfigs()` helper — orders are keyed by tick.

```ts
import {
  getOrderTick,
  getPdaExBitmapAccount,
  CLMM_PROGRAM_ID,
} from "@raydium-io/raydium-sdk-v2";

const { poolInfo, rpcData } = await raydium.clmm.getSimplePoolInfo(POOL_ID);

// Limit price MUST be quantized to tick_spacing — getOrderTick does that.
const targetPrice = new Decimal(180);                              // sell SOL at 180 USDC
const orderData = getOrderTick({
  baseIn: true,                                                    // selling mintA
  mintADecimal: poolInfo.mintA.decimals,
  mintBDecimal: poolInfo.mintB.decimals,
  tickSpacing: poolInfo.config.tickSpacing,
  price: targetPrice,
});

// A sell order must sit above the current tick; a buy order below it.
if (orderData.tick < rpcData.tickCurrent) throw new Error("sell price must be > current price");

const { execute, extInfo } = await raydium.clmm.openLimitOrder({
  poolInfo,
  baseIn: true,
  orderTick: orderData.tick,
  amount: new BN(50_000_000),                // 0.05 SOL
  tickArrayBitmap: getPdaExBitmapAccount(
    CLMM_PROGRAM_ID,
    new PublicKey(poolInfo.id),
  ).publicKey,
  // noneIndex: 0,                           // optional, defaults to 0
  txVersion: TxVersion.V0,
});

const { txId } = await execute({ sendAndConfirm: true });
console.log("Limit order opened:", extInfo.limitOrder.toBase58(), "tx:", txId);

The SDK derives the LimitOrderState PDA from (owner, nonce PDA, order nonce), bumps the per-wallet LimitOrderNonce, and inserts the order into the FIFO cohort at that tick.

Increase / decrease an open order

const limitOrder = new PublicKey("<LIMIT_ORDER_PDA>");

await raydium.clmm.increaseLimitOrder({
  poolInfo,
  limitOrder,
  amount: new BN(20_000_000),
  txVersion: TxVersion.V0,
}).then((b) => b.execute({ sendAndConfirm: true }));

await raydium.clmm.decreaseLimitOrder({
  poolInfo,
  limitOrder,
  amount: new BN(10_000_000),
  slippage: 100,                 // optional; DecreaseLimitOrder adds this over Increase
  txVersion: TxVersion.V0,
}).then((b) => b.execute({ sendAndConfirm: true }));

decreaseLimitOrder can only remove from the unfilled portion of the order; the filled portion is locked until settlement. Both instructions revert with InvalidOrderPhase if the order has already been fully filled.

Settle a filled order

// settleLimitOrder takes ONLY the order PDA — no poolInfo, no poolKeys.
await raydium.clmm.settleLimitOrder({
  limitOrder,
  txVersion: TxVersion.V0,
}).then((b) => b.execute({ sendAndConfirm: true }));

settleLimitOrder reads the order’s unfilled_ratio_x64 against the cohort tracker, computes the filled output, and transfers it to the owner’s ATA. The owner can call this themselves; limit_order_admin (an off-chain operational keeper) can also call it on the owner’s behalf — the output still goes to the owner. For closing fully-settled orders to recover rent, use closeLimitOrder (single) or closeAllLimitOrder (batch). For settling many at once, settleAllLimitOrder packs as many SettleLimitOrder calls as fit into a v0 tx.

List a wallet’s parked orders (off-chain)

// API helper. See api-reference/temp-api-v1.
const active = await fetch(
  `https://temp-api-v1.raydium.io/limit-order/order/list?wallet=<your-wallet-pubkey>`,
).then((r) => r.json());

The active-orders endpoint returns both unfilled and partially-filled orders in one payload (totalAmount / filledAmount / pendingSettle distinguish the phases). For closed-order history use /limit-order/history/order/list-by-user?wallet=… (per-wallet, paginated by nextPageId); for the full event log of a specific order use /limit-order/history/event/list-by-pda?pda=….

Remaining-account order for SwapV2:

[tick_array_bitmap_extension?, tick_array_0, tick_array_1, …]

If the swap never needs the extension, omit it; otherwise it is the first remaining account.

Common pitfalls

Off-spacing tick endpoints → TickAndSpacingNotMatch. Always snap via TickUtil.getPriceAndTick (singular TickUtil).
Not enough tick arrays supplied in SwapV2 → NotEnoughTickArrayAccount. Take the list from swapInternal(...).accounts.
Full-range position without the bitmap extension → the extension PDA must be writable; the SDK handles this automatically.
Mistaking sqrt_price_x64 for price → a factor-of-2 confusion here is particularly painful. When in doubt, let the SDK compute it from a human-readable price.
Collecting rewards too eagerly → each collect is a zero-liquidity DecreaseLiquidity and costs one transaction. Batch via harvestAllRewards across many positions, and remember its execute needs { sequentially: true }.
Closing NFT accounts yourself → ClosePosition burns the NFT and closes its ATA. It also closes a Token-2022 NFT mint; a classic SPL Token mint remains at supply zero because that program cannot close mints. Do not close supported accounts separately or the instruction will revert.
Opening a limit order at a non-spaced tick → TickAndSpacingNotMatch. Always quantize via the exported getOrderTick helper.
Calling decreaseLimitOrder on a fully-filled order → InvalidOrderPhase. Use settleLimitOrder then closeLimitOrder instead.
Expecting an enableDynamicFee flag → there is none. Omitting dynamicFeeConfig simply creates a static-fee pool, silently and with no error. If you wanted dynamic fees, pass the config account’s PublicKey, picked from /main/clmm-dynamic-config.
