How to Build a Raydium Launchpad Bonding Curve in 5 Minutes with forgekit

If you've ever tried building a token launchpad or a bonding curve on Solana, you already know the pain. You spend hours wrestling with complex SDKs, trying to figure out the precise math for a bonding curve, ensuring your token mints are actually "rug-proof," and praying your Raydium CPMM pool creation doesn't fail silently.

Most of the tools out there are heavy, monolithic, and full of dependencies you don't need.

That’s why we built forgekit (@forgekit-labs) - a modular, zero-dependency toolkit that breaks down Solana token launches and Raydium infrastructure into pure, highly-focused functions.

In this tutorial, I'll show you how to use forgekit to calculate a bonding curve, execute a secure token mint, and graduate a token to a Raydium CPMM pool in under 5 minutes.

What is forgekit?

forgekit is a collection of 8 single-purpose npm packages. Instead of forcing you to install a massive SDK, you only install exactly what you need:

@forgekit-labs/curve: Pure bonding curve math (no network required).
@forgekit-labs/token: Atomic token minting with built-in authority revocation.
@forgekit-labs/launchpad: Raydium CPMM pool creation.
@forgekit-labs/meta: Arweave upload via Turbo.
...and more for LP splitting, fees, and v0 transaction building.

Let's build.

Step 1: Install the Modules

For a standard bonding curve launch, you only need three modules. Let's pull them down:

npm install @forgekit-labs/curve @forgekit-labs/token @forgekit-labs/launchpad

Step 2: Calculate the Bonding Curve

Bonding curves require precise math. Instead of writing custom logic to calculate market caps, progress, and thresholds, we use the pure functions from @forgekit-labs/curve.

Because this package is mathematically pure, it requires zero network calls and executes instantly.

import { calculateGraduationThreshold, getCurveProgress } from '@forgekit-labs/curve';

// Define your curve parameters
const startingPriceLamports = 1000; // Starting price in lamports
const targetSol = 85; // E.g., Graduate the curve when 85 SOL is raised

// Calculate exactly how many tokens need to be sold to hit the threshold
const thresholdTokens = calculateGraduationThreshold(startingPriceLamports, targetSol);

console.log(`To graduate, we need to sell ${thresholdTokens} tokens.`);

Step 3: The "Rug-Proof" Atomic Mint

One of the biggest issues with token launches is ensuring the creator actually revokes the Mint and Freeze authorities. If these aren't revoked, the token isn't safe.

@forgekit-labs/token handles this natively. It bundles the minting and authority revocation into a single, atomic transaction. If the revocation fails, the entire mint fails - guaranteeing safety.

import { createAtomicMintTx } from '@forgekit-labs/token';

// Build the transaction
const unsignedTx = await createAtomicMintTx({
  connection,
  creatorPubkey: userWallet.publicKey,
  name: "My Awesome Token",
  symbol: "MAT",
  metadataUri: "https://arweave.net/...", // Use @forgekit-labs/meta to get this!
  decimals: 6,
  totalSupply: 1_000_000_000,
});

// Send this unsigned v0 transaction to the frontend for the user to sign

Step 4: Graduate to Raydium CPMM

Once your curve hits its SOL threshold, it's time to graduate. The token needs to migrate to a Raydium CPMM liquidity pool. Doing this manually involves massive boilerplate.

With @forgekit-labs/launchpad, it's a single, idempotent call. It includes built-in validation and fee configuration.

import { createCpmmPool } from '@forgekit-labs/launchpad';

const graduationResult = await createCpmmPool({
  connection,
  baseMint: tokenAddress,
  quoteMint: "So11111111111111111111111111111111111111112", // Wrapped SOL
  baseAmount: thresholdTokens,
  quoteAmount: targetSol,
  // forgekit automatically handles idempotency and validation under the hood
});

console.log(`Graduation successful! Pool ID: ${graduationResult.poolAddress}`);

Conclusion

That’s it. No bloated SDKs, no guessing the math, and no worrying about whether your token authorities were actually revoked.

By splitting these complex actions into isolated, modular packages, @forgekit-labs gives you the exact tools you need to build a premium launchpad or trading terminal, without the headache.
