Create Pool

​

1. Introduction to Pool Types

​

Overview

​

Splash Pools vs. Concentrated Liquidity Pools

• Splash Pools: Splash Pools are the simplest type of liquidity pool. They are ideal for those looking to launch a new token with minimal parameters. You only need to provide the mint addresses of the two tokens and set the initial price. Splash Pools offer an easy entry point into liquidity provision, making them especially appealing for community-driven projects like memecoins. These projects often prioritize community engagement over technical complexity, and Splash Pools provide a straightforward way to get started.
• Concentrated Liquidity Pools: Concentrated Liquidity Pools are more advanced and allow liquidity providers to concentrate their liquidity within specific price ranges. This results in higher capital efficiency but requires a deeper understanding of how to manage liquidity. Concentrated Liquidity Pools are better suited for experienced users who want greater control over their liquidity.

2. Getting Started Guide

• Client Setup: Create a WhirlpoolClient instance.
• Wallet Connection: Connect a wallet to interact with the Solana network.
• Token Ordering: Ensure your token mints are properly ordered.

​

Creating Splash Pools

1. Token Addresses: Define the two token mint addresses.
2. Set Initial Price: Set the price of the first token in terms of the second token.
3. Create the Pool: Use the createSplashPool function to create the pool.

import { buildWhirlpoolClient } from "@orca-so/whirlpools-sdk";
import { PublicKey } from "@solana/web3.js";
import { Decimal } from "decimal.js";
import { getCtx } from "../utils";

const ctx = getCtx();
const client = buildWhirlpoolClient(ctx);

const devnetWhirlpoolsConfig = new PublicKey(
	"FcrweFY1G9HJAHG5inkGB6pKg1HZ6x9UC2WioAfWrGkR",
);
const tokenAddressA = new PublicKey(
	"So11111111111111111111111111111111111111112",
); // SOL
const tokenAddressB = new PublicKey(
	"BRjpCHtyQLNCo8gqRUr8jtdAj5AjPYQaoqbvcZiHok1k",
); // devUSDC
const initialPrice = new Decimal(0.01);

const { poolKey, tx } = await client.createSplashPool(
	devnetWhirlpoolsConfig,
	tokenAddressA,
	tokenAddressB,
	initialPrice,
	ctx.wallet.publicKey,
);

const txId = await tx.buildAndExecute();
console.log(`Pool created at: ${poolKey.toBase58()}`);
console.log(`Transaction ID: ${txId}`);

​

Creating Concentrated Liquidity Pools

1. Token Addresses: Define the two token mint addresses.
2. Define Tick Spacing: Set the tick spacing based on your fee tier.
3. Convert Price to Tick Index: Calculate the tick index from your desired price.
4. Create the Pool: Use the createPool function to create the concentrated liquidity pool.

import { buildWhirlpoolClient, PriceMath } from "@orca-so/whirlpools-sdk";
import { PublicKey } from "@solana/web3.js";
import { Decimal } from "decimal.js";
import { getCtx } from "../utils";

const ctx = getCtx();
const client = buildWhirlpoolClient(ctx);

const devnetWhirlpoolsConfig = new PublicKey(
	"FcrweFY1G9HJAHG5inkGB6pKg1HZ6x9UC2WioAfWrGkR",
);
const tokenAddressA = new PublicKey(
	"So11111111111111111111111111111111111111112",
); // SOL
const tokenAddressB = new PublicKey(
	"BRjpCHtyQLNCo8gqRUr8jtdAj5AjPYQaoqbvcZiHok1k",
); // devUSDC
const decimalsA = 9;
const decimalsB = 6;
const tickSpacing = 64;
const initialPrice = new Decimal(0.01);
const initialTickIndex = PriceMath.priceToTickIndex(
	initialPrice,
	decimalsA,
	decimalsB,
);

const { poolKey, tx: createPoolTxBuilder } = await client.createPool(
	devnetWhirlpoolsConfig,
	tokenAddressA,
	tokenAddressB,
	tickSpacing,
	initialTickIndex,
	ctx.wallet.publicKey,
);

const createPoolTxId = await createPoolTxBuilder.buildAndExecute();
console.log(`Pool created at: ${poolKey.toBase58()}`);
console.log(`Transaction ID: ${createPoolTxId}`);

​

Important Considerations

• Token Ordering: Tokens must be cardinally ordered. Use the orderMints helper.
• Price Representation: For concentrated pools, price must be converted to a tick index.
• Fee Tiers: Different tick spacings correspond to different fee tiers.
