Usage

This library provides functions to interact with the Pump.fun protocol on Solana, specifically for buying, selling tokens, and getting current prices.

$3

The buy function creates a versioned transaction for buying tokens from a Pump.fun bonding curve.

`typescript
import { buy } from 'solana-pumpfun-api';
import { Connection, Keypair } from '@solana/web3.js';
import bs58 from 'bs58';

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.fromSecretKey(bs58.decode('SECRET_KEY')); // Replace with your wallet
const address = 'TOKEN_MINT_ADDRESS';
const sol = 0.1;
const amount = await getAmount(sol, address);

const transaction = await buy({
walletAddress: wallet.publicKey.toString(),
address,
sol,
amount,
connection,
});

transaction.sign([wallet])

const signature = await connection.sendTransaction(transaction);
`

$3

The sell function creates a versioned transaction for selling tokens back to the Pump.fun bonding curve.

`typescript
import { sell } from 'solana-pumpfun-api';
import { Connection, Keypair } from '@solana/web3.js';
import bs58 from 'bs58';

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.fromSecretKey(bs58.decode('SECRET_KEY')); // Replace with your wallet
const address = 'TOKEN_MINT_ADDRESS';
const amount = 10000000;
const sol = await getSol(amount, address);

const transaction = await sell({
walletAddress: wallet.publicKey.toString(),
address,
sol,
amount,
connection,
});

transaction.sign([wallet])

const signature = await connection.sendTransaction(transaction);
`

$3

The getAmount function calculates the number of tokens you can buy with a given amount of SOL, accounting for slippage.

`typescript
import { getAmount } from 'solana-pumpfun-api';

const tokenAmount = await getAmount('TOKEN_MINT_ADDRESS', 0.1, connection);
console.log(Tokens for 0.1 SOL: ${tokenAmount});
`

$3

The getSol function calculates the SOL you will receive for selling a given number of tokens, accounting for slippage.

`typescript
import { getSol } from 'solana-pumpfun-api';

const solAmount = await getSol('TOKEN_MINT_ADDRESS', 1000000, connection);
console.log(SOL for 1 token: ${solAmount});
`

$3

The buy function creates a versioned transaction for buying tokens from a Pump.fun bonding curve.

`typescript
import { buy, getAmount } from 'solana-pumpfun-api';
import { Connection, Keypair } from '@solana/web3.js';
import bs58 from 'bs58';
import sendTransaction from "solana-transaction-sender";

let withCreateAccount = true;

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.fromSecretKey(bs58.decode('SECRET_KEY'));
const sol = 0.1;
const address = 'TOKEN_MINT_ADDRESS';
const amount = await getAmount(address, sol, connection);

const transaction = await buy({
walletAddress: wallet.publicKey.toString(),
address,
sol,
amount,
connection,
priorityFee: 0.001, // Prioritize your transaction
withCreateAccount, // Create token account once to reduce fee
tokenInfoRevalidate: 200_000, // Cache pump.fun http api in ms
});

// Disable account creation after the first transaction
withCreateAccount = false;
transaction.sign([wallet])

const signature = await sendTransaction(transaction, {
connection,
commitment: "processed", // Return status if solana leader got transaction
maxAttempts: 30,
repeatTimeout: 50, // Spam validator to get prioritized queue
mode: "fast",
});

console.log('Transaction sent: https://solscan.io/tx/' + signature)
`

TradeOptions Interface

`typescript
interface TradeOptions {
walletAddress: string;
address: string;
amount: number;
sol: number;
connection: Connection;
tokenInfoRevalidate?: number;
withCreateAccount?: boolean;
priorityFee?: number;
}
`

- walletAddress: The public key of the wallet as a string.
- address: The mint address of the token.
- amount: The number of whole tokens to buy/sell (the instruction uses amount * 1_000_000 for 6-decimal tokens).
- sol: For buy: max SOL to spend. For sell: min SOL to receive.
- connection: Solana RPC connection.
- tokenInfoRevalidate: Cache duration for token info in ms (default 60s).
- withCreateAccount: Whether to include ATA creation (default: true).
- priorityFee: Priority fee in SOL (default: 0).

Create IPFS Metadata

The createIpfs function uploads metadata to IPFS for token creation.

`typescript
import { createIpfs } from 'solana-pumpfun-api';

const metadataUri = await createIpfs({
image: new Blob([...]), // Your image blob
name: 'My Token',
symbol: 'MTK',
description: 'Description',
twitter: 'https://twitter.com/...',
telegram: 'https://t.me/...',
website: 'https://...',
});
`

Create Coin (Token)

The createCoin function creates a new token on Pump.fun, returning a transaction and mint address.

`typescript
import { createCoin } from 'solana-pumpfun-api';
import { Connection, Keypair } from '@solana/web3.js';
import bs58 from 'bs58';

const connection = new Connection('https://api.mainnet-beta.solana.com');
const wallet = Keypair.fromSecretKey(bs58.decode('SECRET_KEY'));
async function imageUrlToBlob(url: string): Promise {
const response = await fetch(url);
return await response.blob();
}
const blob = await imageUrlToBlob('https://pump.fun/logo.png')

const { transaction, mint } = await createCoin({
walletAddress: wallet.publicKey.toString(),
image: blob,
name: 'My Token',
symbol: 'MTK',
description: 'Description',
twitter: 'https://twitter.com/...',
telegram: 'https://t.me/...',
website: 'https://...',
priorityFee: 0.001,
});

// Sign and send the transaction
transaction.sign([wallet]);
const signature = await connection.sendTransaction(transaction);
console.log(Token created: ${mint});
