CLMM code demos

End-to-end TypeScript examples: create a CLMM pool, open a position in a chosen price range, adjust liquidity, swap, and collect fees and rewards.

Version banner. All demos target @raydium-io/raydium-sdk-v2@0.2.42-alpha against Solana mainnet-beta, verified 2026-04. 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

const ammConfigs = await raydium.api.getClmmConfigs();
const ammConfig  = ammConfigs.find((c) => c.index === 1)!;        // 0.05% tier

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,
  startTime: new BN(0),
  txVersion: TxVersion.V0,
});

const { txId } = await execute({ sendAndConfirm: true });
console.log("Pool:", extInfo.address.id.toBase58(), "tx:", txId);

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, TickUtils } from "@raydium-io/raydium-sdk-v2";

const poolId = new PublicKey("<POOL_ID>");
const { poolInfo, poolKeys, rpcData } = await raydium.clmm.getPoolInfoFromRpc(poolId);

// 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.
const { tick: tickLower } = TickUtils.getPriceAndTick({
  poolInfo, price: lowerPrice, baseIn: true,
});
const { tick: tickUpper } = TickUtils.getPriceAndTick({
  poolInfo, price: upperPrice, baseIn: true,
});

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

const res = 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 automatically computes which tick arrays the range touches and bundles InitTickArray instructions if any are uninitialized.

Increase liquidity on an existing position

Source: src/clmm/increaseLiquidity.ts

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

const positionAccount = await raydium.clmm.getPositionInfo({
  nftMint: positionNftMint,
});

const { execute } = await raydium.clmm.increasePositionFromBase({
  poolInfo,
  poolKeys,
  ownerPosition: positionAccount,
  base: "MintA",
  baseAmount: new BN(5_000_000),
  otherAmountMax: new BN(1_000_000_000),
  txVersion: TxVersion.V0,
});

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,
  liquidity: positionAccount.liquidity.divn(2),   // halve
  amountMinA: new BN(0),
  amountMinB: new BN(0),
  closePosition: false,
  txVersion: TxVersion.V0,
});

await execute({ sendAndConfirm: true });

To collect fees only, call decreaseLiquidity with liquidity = new BN(0). The instruction’s side-effect is settling tokens_fees_owed_{0,1} and transferring them out.

To close the position entirely after zeroing liquidity and fees, pass closePosition: true on the final decreaseLiquidity call. The SDK appends ClosePosition and burns the NFT.

Collect reward(s)

Source: src/clmm/harvestAllRewards.ts

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

await execute({ sendAndConfirm: true });

harvestAllRewards walks every position on every pool passed in, batches CollectReward (and any UpdateRewardInfos) instructions, and splits them across transactions if needed.

Swap

Source: src/clmm/swap.ts

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

const amountIn = new BN(10_000_000);
const baseIn   = true;               // swap A (SOL) → B (USDC)
const slippage = 0.005;

const { minAmountOut, remainingAccounts, priceImpact } =
  PoolUtils.computeAmountOutFormat({
    poolInfo,
    tickArrayCache: await raydium.clmm.fetchTickArrays({ poolInfo }),
    amountIn,
    tokenOut: poolInfo.mintB,
    slippage,
    epochInfo: await raydium.fetchEpochInfo(),
  });

const { execute } = await raydium.clmm.swap({
  poolInfo,
  poolKeys,
  inputMint: new PublicKey(poolInfo.mintA.address),
  amountIn,
  amountOutMin: minAmountOut.amount,
  observationId: poolKeys.observationId,
  remainingAccounts,
  txVersion: TxVersion.V0,
});

await execute({ sendAndConfirm: true });

computeAmountOutFormat walks the tick map off-chain using the same logic as the on-chain program and returns:

• the expected amount out,
• the minimum amount out after slippage,
• the list of tick-array accounts the actual swap will touch (remainingAccounts).

Always pass remainingAccounts returned by the simulation: if you pass too few, the swap reverts mid-walk with TickArrayNotFound; if you pass stale ones, wasted compute.

Create a customizable CLMM pool

createCustomizablePool is the new entry point that exposes the dynamic-fee and single-sided-fee toggles at pool-creation time. It takes the same shape as createPool plus three 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,
  startTime: new BN(0),
  // New fields:
  collectFeeOn:        CollectFeeOn.Token1Only,   // 0 = FromInput, 1 = Token0Only, 2 = Token1Only
  enableDynamicFee:    true,
  dynamicFeeConfigId:  dynamicFeeConfig?.id,      // omit when enableDynamicFee is false
  txVersion: TxVersion.V0,
});

await execute({ sendAndConfirm: true });
console.log("Customizable pool:", extInfo.address.id.toBase58());

createPool continues to work for the default-fee, no-limit-order, no-dynamic-fee path. Use createCustomizablePool whenever you need any of the three new knobs. 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

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

const limitConfigs = await raydium.api.getClmmLimitOrderConfigs(); // GET /main/clmm-limit-order-config
const limitConfig  = limitConfigs.find((c) => c.poolId === poolInfo.id);

// Limit price MUST be quantized to tick_spacing.
const targetPrice = new Decimal(180);                              // sell SOL at 180 USDC
const { tick: limitTick } = TickUtils.getPriceAndTick({
  poolInfo, price: targetPrice, baseIn: true,
});

const { execute } = await raydium.clmm.openLimitOrder({
  poolInfo,
  poolKeys,
  limitOrderConfig: limitConfig,
  inputMint: poolInfo.mintA.address,         // selling SOL
  inputAmount: new BN(50_000_000),           // 0.05 SOL
  tick: limitTick,
  txVersion: TxVersion.V0,
});

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

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

Increase / decrease an open order

await raydium.clmm.increaseLimitOrder({
  poolInfo,
  poolKeys,
  limitOrderId: <LIMIT_ORDER_PUBKEY>,
  addAmount: new BN(20_000_000),
  txVersion: TxVersion.V0,
}).then((b) => b.execute({ sendAndConfirm: true }));

await raydium.clmm.decreaseLimitOrder({
  poolInfo,
  poolKeys,
  limitOrderId: <LIMIT_ORDER_PUBKEY>,
  removeAmount: new BN(10_000_000),
  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

await raydium.clmm.settleLimitOrder({
  poolInfo,
  poolKeys,
  limitOrderId: <LIMIT_ORDER_PUBKEY>,
  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 → InvalidTickIndex. Always snap via TickUtils.getPriceAndTick.
• Not enough tick arrays supplied in SwapV2 → TickArrayNotFound. Use computeAmountOutFormat to get the full list.
• 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 costs one transaction. Batch via harvestAllRewards across many positions.
• Burning the NFT while rent is still owed to the mint → ClosePosition also closes the NFT mint and ATA; do not close them separately or the program will revert.
• Opening a limit order at a non-spaced tick → InvalidTickIndex. Always quantize via TickUtils.getPriceAndTick.
• Calling decreaseLimitOrder on a fully-filled order → InvalidOrderPhase. Use settleLimitOrder then closeLimitOrder instead.
• Forgetting dynamicFeeConfigId while passing enableDynamicFee: true → the CreateCustomizablePool revert is InvalidDynamicFeeConfigParams. Either turn dynamic fee off, or pick a config from /main/clmm-dynamic-config.
