What this does. Creates a new CLMM pool at the fee tier of your choice, then opens an initial concentrated position. Two transactions, one script. Code is lifted from the official demos in raydium-sdk-V2-demo/src/clmm and adapted to a single Node-runnable file.

​
Setup

Make sure you’ve read the Quick start prerequisites and have RPC_URL, KEYPAIR, and the deps installed. CLMM pool creation has a one-time fee plus per-tick-array rent for the initial position. You’ll also need both seed mints in your wallet — opening a position when the price sits inside the chosen range requires liquidity on both sides.

​
Step 1 — config.ts

Save as config.ts. This is the same shape as the demo repo’s src/config.ts.template — disableFeatureCheck is forced to true (recommended for any non-trivial integration so the SDK does not block on its startup feature-detect call): 
// config.ts
import { Raydium, TxVersion, parseTokenAccountResp } from "@raydium-io/raydium-sdk-v2";
import { Connection, Keypair, clusterApiUrl } from "@solana/web3.js";
import { TOKEN_PROGRAM_ID, TOKEN_2022_PROGRAM_ID } from "@solana/spl-token";
import bs58 from "bs58";
import fs from "node:fs";

export const owner: Keypair = Keypair.fromSecretKey(
  // accept either a JSON-array keypair file (same shape Solana CLI writes) or a bs58 secret in env
  process.env.KEYPAIR_BS58
    ? bs58.decode(process.env.KEYPAIR_BS58)
    : new Uint8Array(JSON.parse(fs.readFileSync(process.env.KEYPAIR!, "utf8"))),
);

export const connection = new Connection(
  process.env.RPC_URL ?? clusterApiUrl("mainnet-beta"),
  "confirmed",
);
export const txVersion = TxVersion.V0;
const cluster = "mainnet" as "mainnet" | "devnet";

let raydium: Raydium | undefined;
export const initSdk = async (params?: { loadToken?: boolean }) => {
  if (raydium) return raydium;
  raydium = await Raydium.load({
    owner,
    connection,
    cluster,
    disableFeatureCheck: true,
    disableLoadToken: !params?.loadToken,
    blockhashCommitment: "finalized",
  });
  return raydium;
};

export const fetchTokenAccountData = async () => {
  const solAccountResp = await connection.getAccountInfo(owner.publicKey);
  const tokenAccountResp = await connection.getTokenAccountsByOwner(owner.publicKey, {
    programId: TOKEN_PROGRAM_ID,
  });
  const token2022Req = await connection.getTokenAccountsByOwner(owner.publicKey, {
    programId: TOKEN_2022_PROGRAM_ID,
  });
  return parseTokenAccountResp({
    owner: owner.publicKey,
    solAccountResp,
    tokenAccountResp: {
      context: tokenAccountResp.context,
      value: [...tokenAccountResp.value, ...token2022Req.value],
    },
  });
};

​
Step 2 — createPool.ts

Save alongside config.ts. Source: src/clmm/createPool.ts. 
// createPool.ts
import { CLMM_PROGRAM_ID, DEVNET_PROGRAM_ID } from "@raydium-io/raydium-sdk-v2";
import { PublicKey } from "@solana/web3.js";
import Decimal from "decimal.js";
import { initSdk, txVersion } from "./config";

export const createPool = async () => {
  const raydium = await initSdk({ loadToken: true });

  // RAY
  const mint1 = await raydium.token.getTokenInfo("4k3Dyjzvzp8eMZWUXbBCjEvwSkkk59S5iCNLY3QrkX6R");
  // USDT
  const mint2 = await raydium.token.getTokenInfo("Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB");

  // Fee tiers come from the live API. On devnet the published `id` field is wrong;
  // re-derive the PDA before passing it to the SDK.
  const clmmConfigs = await raydium.api.getClmmConfigs();

  const { execute } = await raydium.clmm.createPool({
    programId: CLMM_PROGRAM_ID,
    // programId: DEVNET_PROGRAM_ID.CLMM_PROGRAM_ID,
    mint1,
    mint2,
    ammConfig: {
      ...clmmConfigs[0],
      id: new PublicKey(clmmConfigs[0].id),
      fundOwner: "",
      description: "",
    },
    initialPrice: new Decimal(1),
    txVersion,
    // optional: set up priority fee here
    // computeBudgetConfig: { units: 600000, microLamports: 46591500 },
  });

  const { txId } = await execute({ sendAndConfirm: true });
  console.log("clmm pool created:", { txId: `https://explorer.solana.com/tx/${txId}` });
  process.exit();
};

createPool();

​
Step 3 — createPosition.ts

Source: src/clmm/createPosition.ts. 
// createPosition.ts
import {
  ApiV3PoolInfoConcentratedItem,
  TickUtils,
  PoolUtils,
  ClmmKeys,
} from "@raydium-io/raydium-sdk-v2";
import BN from "bn.js";
import Decimal from "decimal.js";
import { initSdk, txVersion } from "./config";
import { isValidClmm } from "./utils";

export const createPosition = async () => {
  const raydium = await initSdk();

  let poolInfo: ApiV3PoolInfoConcentratedItem;
  // RAY-USDC pool
  const poolId = "61R1ndXxvsWXXkWSyNkCxnzwd3zUNB8Q2ibmkiLPC8ht";
  let poolKeys: ClmmKeys | undefined;

  if (raydium.cluster === "mainnet") {
    const data = await raydium.api.fetchPoolById({ ids: poolId });
    poolInfo = data[0] as ApiV3PoolInfoConcentratedItem;
    if (!isValidClmm(poolInfo.programId)) throw new Error("target pool is not CLMM pool");
  } else {
    const data = await raydium.clmm.getPoolInfoFromRpc(poolId);
    poolInfo = data.poolInfo;
    poolKeys = data.poolKeys;
  }

  // Optional: pull on-chain real-time price to avoid slippage errors from a stale API quote.
  // const rpcData = await raydium.clmm.getRpcClmmPoolInfo({ poolId: poolInfo.id });
  // poolInfo.price = rpcData.currentPrice;

  const inputAmount = 0.000001; // RAY amount
  const [startPrice, endPrice] = [0.000001, 100000];

  const { tick: lowerTick } = TickUtils.getPriceAndTick({
    poolInfo,
    price: new Decimal(startPrice),
    baseIn: true,
  });
  const { tick: upperTick } = TickUtils.getPriceAndTick({
    poolInfo,
    price: new Decimal(endPrice),
    baseIn: true,
  });

  const epochInfo = await raydium.fetchEpochInfo();
  const res = await PoolUtils.getLiquidityAmountOutFromAmountIn({
    poolInfo,
    slippage: 0,
    inputA: true,
    tickUpper: Math.max(lowerTick, upperTick),
    tickLower: Math.min(lowerTick, upperTick),
    amount: new BN(new Decimal(inputAmount || "0").mul(10 ** poolInfo.mintA.decimals).toFixed(0)),
    add: true,
    amountHasFee: true,
    epochInfo,
  });

  const { execute, extInfo } = await raydium.clmm.openPositionFromBase({
    poolInfo,
    poolKeys,
    tickUpper: Math.max(lowerTick, upperTick),
    tickLower: Math.min(lowerTick, upperTick),
    base: "MintA",
    ownerInfo: { useSOLBalance: true },
    baseAmount: new BN(new Decimal(inputAmount || "0").mul(10 ** poolInfo.mintA.decimals).toFixed(0)),
    otherAmountMax: res.amountSlippageB.amount,
    txVersion,
    computeBudgetConfig: { units: 600000, microLamports: 100000 },
  });

  const { txId } = await execute({ sendAndConfirm: true });
  console.log("clmm position opened:", { txId, nft: extInfo.nftMint.toBase58() });
  process.exit();
};

createPosition();

​
Step 4 — utils.ts

Source: src/clmm/utils.ts. 
// utils.ts
import { CLMM_PROGRAM_ID, DEVNET_PROGRAM_ID } from "@raydium-io/raydium-sdk-v2";

const VALID_PROGRAM_IDS = new Set<string>([
  CLMM_PROGRAM_ID.toBase58(),
  DEVNET_PROGRAM_ID.CLMM_PROGRAM_ID.toBase58(),
]);

export const isValidClmm = (programId: string) => VALID_PROGRAM_IDS.has(programId);

​
Run it

# create the pool first
RPC_URL="https://api.mainnet-beta.solana.com" \
KEYPAIR="$HOME/.config/solana/id.json" \
npx tsx createPool.ts

# then open an initial position against the new pool id
# (edit poolId at the top of createPosition.ts to point at your new pool)
RPC_URL="https://api.mainnet-beta.solana.com" \
KEYPAIR="$HOME/.config/solana/id.json" \
npx tsx createPosition.ts

​
What just happened

Transaction 1 — raydium.clmm.createPool initialized:
  • the pool state at the canonical PDA for (mint1, mint2, ammConfig),
  • token_0_vault and token_1_vault (sorted by mint byte order),
  • the observation ring buffer,
  • the inline tick-array bitmap,
and set the initial sqrt_price_x64 from your initialPrice. Transaction 2 — raydium.clmm.openPositionFromBase opened a concentrated position:
  • minted a position NFT to your wallet (the NFT is the position; transferring it transfers the position),
  • allocated tick arrays at the lower and upper bounds (one-time rent if first position in those ranges; tick arrays are never closed by the program, so subsequent positions in the same arrays pay no extra rent),
  • deposited inputAmount of mint1 and the matching pair amount of mint2 (computed by PoolUtils.getLiquidityAmountOutFromAmountIn),
  • credited the position with liquidity proportional to the range width.
The narrower the range, the higher the capital efficiency per dollar of TVL — and the more painful the impermanent loss when price drifts out of range. The range used above ([0.000001, 100000]) is effectively full-range; tighten it to concentrate fees near current spot.

​
Picking a fee tier

clmmConfigs[0] is the lowest-fee tier. The full set is published at GET https://api-v3.raydium.io/main/clmm-config:
IndextradeFeeRateTick spacingUse when
0100 (1bp)1Stable / stable, very low impermanent loss expected
1500 (5bp)10Highly correlated assets (e.g. liquid-staked vs underlying)
22_500 (25bp)60Standard token pair, blue-chip + stable
310_000 (1.00%)120Volatile or thin pair where IL risk is high
See user-flows/choosing-a-pool-type for a full decision matrix.

​
Common errors

  • Pool already exists for this config — A CLMM pool already exists for this (mint1, mint2, ammConfig) triple. Look up the existing pool ID and skip Step 2.
  • Insufficient funds for amount B — Your wallet has the requested amount of mintA but not the matching mintB. Opening a position when the price sits inside the range requires liquidity on both sides.
  • Tick out of range — Your lowerPrice or upperPrice falls outside the representable price range. Use a more reasonable range relative to current price.
  • Stale price — A quote from the API can be 5–60 seconds stale. If executePosition fails on slippage, uncomment the getRpcClmmPoolInfo block in createPosition.ts to re-fetch the live price right before signing.

​
Caveats

  • Position NFT is your only handle. Lose the NFT or transfer it, lose access to the position. Treat it like a key.
  • Out-of-range positions earn no fees. If price moves outside [lowerPrice, upperPrice], your position is parked entirely in one asset and earns nothing until you rebalance.
  • Tick array rent is one-way. The first position to touch a never-initialised tick array pays its rent; the program does not expose a path to close tick arrays, so that rent is permanent. Subsequent positions in the same array are free.
