Orca Whirlpools Development Guide

Orca is the most trusted DEX on Solana and Eclipse, built on a concentrated liquidity automated market maker (CLMM) called Whirlpools. This guide covers the Whirlpools SDK for building trading, liquidity provision, and pool management applications.

Overview

Orca Whirlpools provides:

• Token Swaps - Efficient token exchanges with low slippage and competitive rates
• Concentrated Liquidity - Provide liquidity within custom price ranges for higher capital efficiency
• Splash Pools - Simple full-range liquidity provision for beginners
• Position Management - Open, increase, decrease, and close liquidity positions
• Fee Harvesting - Collect trading fees and rewards from positions
• Pool Creation - Permissionless creation of new liquidity pools

Program IDs

Quick Start

Installation

New SDK (Solana Web3.js v2):

Copynpm install @orca-so/whirlpools @solana/kit

Legacy SDK (Solana Web3.js v1):

Copynpm install @orca-so/whirlpools-sdk @orca-so/common-sdk @coral-xyz/anchor@0.29.0 @solana/web3.js @solana/spl-token decimal.js

  setWhirlpoolsConfig,
  setRpc,
  setPayerFromBytes
} from "@orca-so/whirlpools";
import { createSolanaRpc, devnet } from "@solana/kit";
import fs from "fs";

// Configure for Solana Devnet
await setWhirlpoolsConfig("solanaDevnet");
await setRpc("https://api.devnet.solana.com");

// Load wallet from keypair file
const keyPairBytes = new Uint8Array(
  JSON.parse(fs.readFileSync("./keypair.json", "utf8"))

Token Swaps

Swap with New SDK

Copyimport { swap, swapInstructions, setWhirlpoolsConfig } from "@orca-so/whirlpools";
import { address } from "@solana/kit";

await setWhirlpoolsConfig("solanaMainnet");

const poolAddress = address("POOL_ADDRESS_HERE");
const inputMint = address("INPUT_TOKEN_MINT");
const amount = 1_000_000n; // Amount in smallest units
const slippageTolerance = 100; // 100 bps = 1%

// Option 1: Use the simple swap function (builds and sends)
const txId = await swap(
  rpc,
  { inputAmount: amount, mint: inputMint },
  poolAddress,
  slippageTolerance,
  wallet
);

console.log("Swap transaction:", txId);

// Option 2: Get instructions for custom transaction building
const { instructions, quote } = await swapInstructions(
  rpc,

  poolAddress,
  slippageTolerance,
  wallet
);

console.log("Expected output:", quote.tokenEstOut);
console.log("Minimum output:", quote.tokenMinOut);
console.log("Price impact:", quote.priceImpact);

Exact Output Swap

Copy// Swap to get exact output amount
const { instructions, quote } = await swapInstructions(

const whirlpoolData = whirlpool.getData();

// Get swap quote
const inputAmount = new Decimal("1.0"); // 1 token
const quote = await swapQuoteByInputToken(
  whirlpool,
  whirlpoolData.tokenMintA,
  DecimalUtil.toBN(inputAmount, 9), // 9 decimals
  Percentage.fromFraction(1, 100), // 1% slippage

  ctx.fetcher
);

console.log("Estimated output:", quote.estimatedAmountOut.toString());

// Execute swap
const tx = await whirlpool.swap(quote);
const signature = await tx.buildAndExecute();

Liquidity Provision

Position Types

Concentrated Liquidity Position: Provide liquidity within a specific price range for higher capital efficiency.

Full Range Position (Splash Pool): Provide liquidity across the entire price range, similar to traditional AMMs.

Open Concentrated Liquidity Position

Copyimport { openPosition, openPositionInstructions } from "@orca-so/whirlpools";
import { address } from "@solana/kit";

const poolAddress = address("POOL_ADDRESS");
const lowerPrice = 0.001;  // Lower bound of price range
const upperPrice = 100.0;  // Upper bound of price range
const slippageTolerance = 100; // 1%

// Specify liquidity by token amount
const param = { tokenA: 1_000_000_000n }; // 1 token with 9 decimals

// Option 1: Simple function that builds and sends
const txId = await openPosition(
  rpc,
  poolAddress,
  param,
  lowerPrice,
  upperPrice,
  slippageTolerance,
  wallet
);

// Option 2: Get instructions for custom transaction
const {
  instructions,
  quote,
  positionMint,
  initializationCost
} = await openPositionInstructions(
  rpc,
  poolAddress,
  param,
  lowerPrice,
  upperPrice,
  slippageTolerance,

const {
  instructions,
  quote,
  positionMint,
  callback: sendTx
} = await openFullRangePositionInstructions(
  rpc,
  poolAddress,
  param,
  slippageTolerance,
  wallet
);

console.log("Position mint:", positionMint);
console.log("Token max B:", quote.tokenMaxB);

// Send the transaction
const txId = await sendTx();
console.log("Transaction:", txId);

Increase Position Liquidity

Copyimport { increaseLiquidity, increaseLiquidityInstructions } from "@orca-so/whirlpools";

const positionMint = address("POSITION_MINT");
const param = { tokenA: 500_000_000n }; // Add 0.5 tokens
const slippageTolerance = 100;

const { instructions, quote } = await increaseLiquidityInstructions(
  rpc,
  positionMint,
  param,
  slippageTolerance,
  wallet
);

console.log("Additional Token A:", quote.tokenEstA);
console.log("Additional Token B:", quote.tokenEstB);

Decrease Position Liquidity

Copyimport { decreaseLiquidity, decreaseLiquidityInstructions } from "@orca-so/whirlpools";

const param = { liquidity: 1000000n }; // Or use tokenA/tokenB
const slippageTolerance = 100;

const { instructions, quote } = await decreaseLiquidityInstructions(
  rpc,
  positionMint,
  param,
  slippageTolerance,
  wallet
);

console.log("Token A received:", quote.tokenEstA);
console.log("Token B received:", quote.tokenEstB);

Harvest Fees and Rewards

Copyimport { harvestPosition, harvestPositionInstructions, harvestAllPositionFees } from "@orca-so/whirlpools";

// Harvest single position
const positionMint = address("POSITION_MINT");

const { instructions, feesQuote, rewardsQuote } = await harvestPositionInstructions(
  rpc,
  positionMint,
  wallet
);

console.log("Fee Token A:", feesQuote.feeOwedA);
console.log("Fee Token B:", feesQuote.feeOwedB);
console.log("Rewards:", rewardsQuote);

// Harvest all positions at once
const { instructions: harvestAllIx, fees, rewards } = await harvestAllPositionFees(
  rpc,
  wallet.address
);

Close Position

Copyimport { closePosition, closePositionInstructions } from "@orca-so/whirlpools";

const positionMint = address("POSITION_MINT");
const slippageTolerance = 100;

const { instructions, quote, feesQuote } = await closePositionInstructions(

Best Practices

Security

1. Never expose private keys - Use environment variables or secure key management
2. Verify pool addresses - Always confirm you're interacting with legitimate pools
3. Use slippage protection - Set appropriate slippage tolerance to prevent front-running
4. Test on devnet first - Validate all operations before mainnet deployment

Performance

1. Use priority fees - Essential for mainnet transactions during high congestion
2. Batch operations - Combine multiple instructions when possible
3. Pre-fetch data - Cache pool and position data to reduce RPC calls

Liquidity Provision

1. Monitor positions - Track when positions go out of range
2. Rebalance strategically - Consider gas costs when adjusting positions
3. Harvest regularly - Collect fees and rewards to compound returns
4. Understand impermanent loss - Concentrated positions have amplified IL risk

Error Handling

Copytry {
  const txId = await swap(rpc, swapParams, poolAddress, slippage, wallet);
} catch (error) {
  if (error.message.includes("SlippageExceeded")) {
    console.error("Slippage tolerance exceeded, try increasing slippage");
  } else if (error.message.includes("InsufficientFunds")) {
    console.error("Not enough tokens in wallet");
  } else if (error.message.includes("TickArrayNotInitialized")) {
    console.error("Price range tick arrays not initialized");
  } else {
    throw error;
  }
}
