@picon-finance/dlmm-sdk

TypeScript SDK for the Picon DLMM protocol on Solana, built on @solana/kit.

Install

npm install @picon-finance/dlmm-sdk

Usage

Every action returns an unsigned TransactionMessage — sign and send it with @solana/kit. Actions default to mainnet; pass a programAddress to target another cluster.

import { createSolanaRpc, signTransactionMessageWithSigners, sendAndConfirmTransactionFactory } from "@solana/kit";
import { createPool, swap, quote, getPool, DEVNET_PROGRAM_ADDRESS } from "@picon-finance/dlmm-sdk";

const rpc = createSolanaRpc("https://api.mainnet-beta.solana.com");

// Read
const pool = await getPool(rpc, poolAddress);

// Quote, then build the matching swap transaction
const { quoteOutput, swap: buildSwap } = await quote(rpc, {
  pool: poolAddress,
  xToY: true,
  amountIn: 1_000_000n,
  slippageToleranceBps: 50,
});
const swapMessage = await buildSwap(userSigner);

// Write — target devnet by passing programAddress
const createPoolMessage = await createPool(
  rpc,
  { authority, binStep, feeRate, protocolShare, activeBinId, tokenMintX, tokenMintY, tokenProgramX, tokenProgramY },
  DEVNET_PROGRAM_ADDRESS,
);

// Sign and send however you normally do with @solana/kit
const signed = await signTransactionMessageWithSigners(swapMessage);

MAINNET_PROGRAM_ADDRESS and DEVNET_PROGRAM_ADDRESS are both exported for convenience; omitting programAddress defaults to mainnet.
