🪙 sol-token

A Golang package for creating and managing ERC20-like SPL tokens on the Solana blockchain.

Easily mint, transfer, and manage tokens with optional metadata and supply locking. Built with blocto/solana-go-sdk.

✨ Features

• ✅ Mint new SPL tokens (ERC20-style)
• ✅ Set name, symbol, URI, decimals, and custom metadata
• ✅ Transfer tokens between accounts
• ✅ Automatically create associated token accounts (ATA)
• ✅ Lock mint authority (disable future minting)
• ✅ Optional freeze authority support
• ✅ Lightweight and developer-friendly

🛠️ Installation

go get github.com/ja7ad/sol-token

🚀 Quick Start

client := NewClient(Devnet)
owner := token.NewAccount()
payer := token.NewAccount()
tok := token.NewTokenManager(client, owner, payer)

mintAddr, txHash, err := tok.Mint(ctx, token.MintParams{
    Metadata: token.Metadata{
        Name:     "MyToken",
        Symbol:   "MTK",
        URI:      "https://example.com/token.json",
        Supply:   1000.0,
    },
    DisableFutureMinting: true,
})

Transfer tokens:

_, err = tok.Transfer(ctx, TransferParams{
		Amount:            amount,
		Recipient:         recipient.PublicKey(),
		CheckTokenProgram: true,
	})

🔐 Security Notes

• Only store the mint account private key if you plan to mint more tokens later.
• If DisableFutureMinting is true, minting will be permanently disabled.
