Creating a platform

Create and configure your LaunchLab platform to enable token launches.

Before users can launch tokens on your platform, you need to create a platform configuration. Each wallet can only create one platform.

Creating a platform

Use createPlatformConfig() to initialize your platform with fee structures, LP distribution settings, and metadata.

import {
  TxVersion,
  LAUNCHPAD_PROGRAM,
  DEVNET_PROGRAM_ID,
} from '@raydium-io/raydium-sdk-v2'
import { initSdk } from './config'
import { PublicKey } from '@solana/web3.js'
import BN from 'bn.js'

const createPlatform = async () => {
  const raydium = await initSdk()
  const owner = raydium.ownerPubKey

  const { execute, extInfo } = await raydium.launchpad.createPlatformConfig({
    programId: LAUNCHPAD_PROGRAM, // Use DEVNET_PROGRAM_ID.LAUNCHPAD_PROGRAM for devnet

    // Wallet configuration
    platformAdmin: owner,
    platformClaimFeeWallet: owner,
    platformLockNftWallet: owner,
    platformVestingWallet: owner,

    // CPMM pool fee tier for migrated pools
    cpConfigId: new PublicKey('DNXgeM9EiiaAbaWvwjHj9fQQLAX5ZsfHyvmYUNRAdNC8'),

    // Token-2022 transfer fee authority (receives fee authorities post-migration)
    transferFeeExtensionAuth: owner,

    // Fee configuration
    feeRate: new BN(10000),        // 1% platform fee on bonding curve trades
    creatorFeeRate: new BN(5000),  // 0.5% creator fee on bonding curve trades

    // LP distribution at migration (must sum to 1,000,000)
    migrateCpLockNftScale: {
      platformScale: new BN(100000),  // 10% to platform (locked)
      creatorScale: new BN(100000),   // 10% to creator (locked)
      burnScale: new BN(800000),      // 80% burned
    },

    // Platform metadata
    name: 'My LaunchLab',
    web: 'https://mylaunchlab.io',
    img: 'https://mylaunchlab.io/logo.png',

    txVersion: TxVersion.V0,
  })

  const { txId } = await execute({ sendAndConfirm: true })
  console.log('Platform created:', extInfo.platformId.toBase58())
}

Configuration parameters

Wallet configuration

Parameter	Type	Description
platformAdmin	PublicKey	Admin wallet that controls the platform. Can update settings.
platformClaimFeeWallet	PublicKey	Wallet that receives platform trading fees from bonding curves.
platformLockNftWallet	PublicKey	Wallet that receives the platform's Fee Key NFT after migration.
platformVestingWallet	PublicKey	Wallet for platform vesting allocations. Use PublicKey.default if not needed.

Fee configuration

Parameter	Type	Description
feeRate	BN	Platform's share of bonding curve trading fees. In bps × 100 (10000 = 1%).
creatorFeeRate	BN	Creator's share of bonding curve trading fees. In bps × 100 (5000 = 0.5%). Max 50000 (5%).

Fees are denominated in quote token (e.g., SOL). For each trade, total fee = protocolFeeRate + platformFeeRate + creatorFeeRate + shareFeeRate. Each party receives their proportional share.

LP distribution at migration

Parameter	Type	Description
platformScale	BN	Platform's share of LP tokens, locked via Burn & Earn. Platform receives Fee Key NFT.
creatorScale	BN	Creator's share of LP tokens, locked via Burn & Earn. Creator receives Fee Key NFT.
burnScale	BN	LP tokens burned permanently. No fees generated.

These three values must sum to 1,000,000 (100%).

Example distributions:

// 80% burned, 10% creator, 10% platform
{ burnScale: 800000, creatorScale: 100000, platformScale: 100000 }

// 90% burned, 10% creator (no platform share)
{ burnScale: 900000, creatorScale: 100000, platformScale: 0 }

// 100% burned (no ongoing fees)
{ burnScale: 1000000, creatorScale: 0, platformScale: 0 }

Pool configuration

Parameter	Type	Description
cpConfigId	PublicKey	Fee tier for the CPMM pool after migration. Get available configs from the API.
transferFeeExtensionAuth	PublicKey	Receives transfer fee authorities for Token-2022 launches after migration.

Available CPMM configs:

• Mainnet: https://api-v3.raydium.io/main/cpmm-config

• Devnet: https://api-v3-devnet.raydium.io/main/cpmm-config

Metadata

Parameter	Type	Description
name	string	Platform name (stored on-chain).
web	string	Platform website URL.
img	string	Platform logo URL.

Updating platform configuration

Platform settings can be updated once per epoch. Use updatePlatformConfig() to modify settings.

const updatePlatform = async () => {
  const raydium = await initSdk()

  const { execute } = await raydium.launchpad.updatePlatformConfig({
    platformAdmin: raydium.ownerPubKey,

    // Update a single setting
    updateInfo: { type: 'updateFeeRate', value: new BN(15000) }, // Change to 1.5%

    txVersion: TxVersion.V0,
  })

  await execute({ sendAndConfirm: true })
}

Available update types

Type	Value	Description
updateFeeRate	BN	Update platform trading fee rate
updateClaimFeeWallet	PublicKey	Change fee collection wallet
updateLockNftWallet	PublicKey	Change Fee Key NFT recipient
updateVestingWallet	PublicKey	Change vesting wallet
updateCpConfigId	PublicKey	Change CPMM fee tier for migrations
updateName	string	Update platform name
updateWeb	string	Update website URL
updateImg	string	Update logo URL
migrateCpLockNftScale	object	Update LP distribution ratios
updatePlatformVestingScale	BN	Update platform vesting allocation
updateAll	object	Update all settings at once

Only one update can be made per epoch. Plan changes carefully.

Enforcing launch parameters (optional)

Platforms can restrict which token configurations are allowed. If a creator's parameters don't match an allowed configuration, the transaction fails.

import { updatePlatformCurveParamInstruction } from '@raydium-io/raydium-sdk-v2'

// Add an allowed configuration at index 1
const instruction = updatePlatformCurveParamInstruction(
  LAUNCHPAD_PROGRAM,
  platformAdmin,
  platformId,
  1, // index (0-254)
  {
    migrateType: 1,                              // 0 = AMM, 1 = CPMM
    migrateCpmmFeeOn: 0,                         // Creator fee token
    supply: new BN('1000000000000000'),          // 1B tokens (with decimals)
    totalSellA: new BN('793100000000000'),       // ~79.3% sold on curve
    totalFundRaisingB: new BN('85000000000'),    // 85 SOL to raise
    totalLockedAmount: new BN('0'),              // No vesting
    cliffPeriod: new BN('0'),
    unlockPeriod: new BN('0'),
  }
)

How parameter enforcement works

• Store up to 25 configurations (index 0-254)

• Set a parameter to null to skip validation for that field

• Creators must match at least one configuration exactly

• Configurations can be updated once per epoch

Example: Allow flexible raise amounts but fixed supply:

{
  supply: new BN('1000000000000000'),     // Must be exactly 1B
  totalFundRaisingB: null,                // Any amount allowed
  // ... other params
}

Deriving your platform ID

After creation, your platform ID is derived from your admin wallet:

import { getPdaPlatformId, LAUNCHPAD_PROGRAM } from '@raydium-io/raydium-sdk-v2'

const { publicKey: platformId } = getPdaPlatformId(
  LAUNCHPAD_PROGRAM,
  adminWallet
)

Share this platformId with token creators who want to launch on your platform.
