how to create market id in devnet with js

Question

I was learning solana evm on devnet and I started to code a token with @solana/spl-token library and then I tried to add a liquidity to radiyum and then it asked for openbook market id , I want to know how can I generate openbook market id and why does it cost 2.78 SOL , can i just generate it myself?

Answer 1

You might assume generating a market ID in Solana is relevant to creating a token pair in Ethereum. It's a prerequisite step for creating a LP in Solana.

The cost you're seeing (2.78 SOL) is due to the rent exempt status of accounts and transaction fees.

Here are some links for your reference.

Below is my working example.

const {
    MarketV2,
    MAINNET_PROGRAM_ID,
    DEVNET_PROGRAM_ID
} = require('@raydium-io/raydium-sdk')

const {
    connection,
    makeTxVersion,
} = require('../config.js')
const { buildAndSendTx } = require('./util')

async function createMarket(input) {
    const RAYDIUM_PROGRAM_ID = process.env.NETWORK == 'mainnet' ? MAINNET_PROGRAM_ID : DEVNET_PROGRAM_ID

    // -------- step 1: make instructions --------
    const createMarketInstruments = await MarketV2.makeCreateMarketInstructionSimple({
        connection,
        wallet: input.wallet.publicKey,
        baseInfo: input.baseToken,
        quoteInfo: input.quoteToken,
        lotSize: input.lotSize, // default 1
        tickSize: input.tickSize, // default 0.01
        dexProgramId: RAYDIUM_PROGRAM_ID.OPENBOOK_MARKET,
        makeTxVersion,
    })

    marketId = createMarketInstruments.address.marketId

    txids = await buildAndSendTx(createMarketInstruments.innerTransactions, { skipPreflight: true })
    console.log('Market Created')
    console.log('Create Market Transactions :', txids)
    console.log('Market Address :', marketId)

    return marketId
}

module.exports = {
    createMarket
};
