Go Wallet SDK: A Comprehensive Guide to Blockchain Integration

Overview

The Go-wallet-sdk is a versatile Go-based wallet solution that supports multiple blockchain networks with diverse cryptographic algorithms and essential functionalities. Developers can use it for offline private key generation, address creation, transaction assembly, and digital signing. This SDK currently supports major blockchain protocols, with plans to expand coverage to additional networks.

Supported Platforms

As a Go SDK, it seamlessly integrates with:

Web applications
Mobile apps
Desktop software

Installation and Setup

Using Go GET

Install the latest version via:

go get github.com/okx/go-wallet-sdk

The SDK offers two package types:

Common packages (cross-chain functionalities)
Coin-specific modules (e.g., ETH, BTC)
