Pump.fun

Pump.fun is the most popular memecoin launchpad on Solana. It uses a bonding curve mechanism where tokens are initially traded along a price curve, then graduate to Raydium once the curve is filled. dex-skills integrates with Pump.fun via the PumpPortal API, handling IPFS metadata uploads and transaction construction automatically.

Setup

Initialize dex-skills for Pump.fun

import { createSkills, getSkill } from "dex-skills";

const skills = createSkills({
  wallets: {
    solana: {
      privateKey: "your-base58-private-key",
      rpcUrl: "https://api.mainnet-beta.solana.com",
    },
  },
});

const pumpfun = getSkill(skills, "pumpfun");

Launch a Token

Launching a token on Pump.fun creates a new bonding curve token. The metadata (name, symbol, description, image) is uploaded to IPFS automatically. The token is immediately tradeable on the bonding curve after creation.

Launch Example

const result = await pumpfun.launch({
  name: "My Token",
  symbol: "MYTKN",
  description: "A sample token launched via dex-skills.",
  imageUrl: "https://example.com/logo.png",
  initialBuyAmount: "0.1",
  links: {
    twitter: "https://x.com/mytoken",
    telegram: "https://t.me/mytoken",
    website: "https://mytoken.xyz",
  },
});

console.log("Token address:", result.tokenAddress);
console.log("Transaction:", result.txHash);

Launch Parameters

Parameter	Type	Description
name *	string	Display name of the token.
symbol *	string	Token ticker symbol.
description	string	Description of the token.
imageUrl	string	Token image URL. Uploaded to IPFS.
initialBuyAmount	string	Initial buy amount in SOL.
links.twitter	string	Twitter/X profile URL.

console.log("Name:", token.name);
console.log("Symbol:", token.symbol);
console.log("Market Cap:", token.marketCap);
console.log("Bonding Curve Progress:", token.bondingCurveProgress);

List Tokens

const tokens = await pumpfun.listTokens({
  limit: 20,
  sortBy: "createdAt",

for (const token of tokens) {
  console.log(token.symbol, token.tokenAddress);
}

Buy Tokens

  tokenAddress: "TokenMintAddress...",
  amount: "0.1",
  slippage: 10,
});

console.log("Tx Hash:", result.txHash);
console.log("Tokens received:", result.tokenAmount);

Sell Tokens

  tokenAddress: "TokenMintAddress...",
  amount: "1000000",
  slippage: 10,
});

console.log("Tx Hash:", result.txHash);
console.log("SOL received:", result.nativeAmount);

Get Trending

Trending Tokens

const trending = await pumpfun.getTrending({
  category: "gainers",
  limit: 20,
});

for (const token of trending) {
  console.log(token.symbol, token.marketCap);
}

Platform Notes

Bonding Curve Mechanics

Tokens launched on Pump.fun start on a bonding curve. As buyers purchase the token, the price increases along the curve. Once the bonding curve reaches its target (approximately 85 SOL in liquidity), the token graduates to Raydium and begins trading as a standard AMM pool. The graduation process is automatic.

IPFS Metadata

Token metadata including the image is uploaded to IPFS via the PumpPortal API during launch. Ensure your image file is accessible at the provided path. Large images may increase upload time.
