I can help you troubleshoot the Solana token selling issue . This sounds like you're dealing with keypair/public key encoding problems. Let me address the common issues

Common Problems with Solana Keys

Base58 vs Base64 confusion:

Solana public keys use Base58 encoding

Private keys (secret keys) are typically stored as Base64 or byte arrays

The .env file format matters

Here's what you likely need

import { Keypair, PublicKey } from '@solana/web3.js';

import bs58 from 'bs58';

// For private key (from phantom wallet export or solana CLI):

// If it's a byte array [1,2,3,...] format:

const privateKey = JSON.parse(process.env.PRIVATE_KEY);

const keypair = Keypair.fromSecretKey(new Uint8Array(privateKey));

// If it's base58 string (more common):

const keypair = Keypair.fromSecretKey(bs58.decode(process.env.PRIVATE_KEY));

// For public key (token mint, recipient addresses):

const tokenMint = new PublicKey(process.env.TOKEN_MINT_ADDRESS);

Your .env should look like

# Private key as base58 string

PRIVATE_KEY=your_base58_private_key_here

# or as byte array (from Phantom export)

PRIVATE_KEY=[123,45,67,...]

# Public addresses are always base58

TOKEN_MINT_ADDRESS=TokenMintAddress111111111111111111111

RECIPIENT_ADDRESS=RecipientAddress11111111111111111111

Common fixes

Install bs58 if you haven't: npm install bs58

Check your private key format - export from Phantom gives you a byte array, Solana CLI gives base58

Public keys should never be decoded - pass them directly to new PublicKey()
