Hardline

Hardline is a Go library for validating blockchain addresses across multiple networks. Currently, it supports Ethereum and Solana addresses.

Features

• Validate Ethereum addresses (including checksum validation)
• Validate Solana addresses
• Easy-to-use API
• Lightweight and efficient

Installation

To install Hardline, run:

go get github.com/dfb-chain/hardline

Usage

Here's how to use Hardline in your Go project:

package main

import (
    "fmt"

    "github.com/dfb-chain/hardline"
)

func main() {
    ethAddress := "0x27B1FdB04752BbC536007A920D24ACB045561C26"
    solAddress := "4Nd1mXwoz5Mn386YvyXg3k94KQgjwBWEknhAQrvV7z5V"

    if hardline.IsValidEthereumAddress(ethAddress) {
        fmt.Println("Valid Ethereum address")
    } else {
        fmt.Println("Invalid Ethereum address")
    }

    if hardline.IsValidSolanaAddress(solAddress) {
        fmt.Println("Valid Solana address")
    } else {
        fmt.Println("Invalid Solana address")
    }
}

Documentation

IsValidEthereumAddress

func IsValidEthereumAddress(address string) bool

Checks if the provided string is a valid Ethereum address. It supports addresses with or without the 0x prefix and verifies the checksum if the address is in mixed case.

IsValidSolanaAddress

func IsValidSolanaAddress(address string) bool

Checks if the provided string is a valid Solana address by decoding it from Base58 and verifying that it is 32 bytes long.
