🛠️ Architecture

The Go Wallet SDK follows a modular architecture, comprising the following core components:

1. coins: Implements transaction creation and signing for each blockchain.
2. crypto: Manages general cryptographic operations and signature algorithms.
3. util: Provides helper utilities for common operations.

This structure allows for easy integration and extension of new blockchains.

📦 Installation

To install the OKX Web3 Go Wallet SDK, ensure you have Go 1.22+ installed, such as run:

# Install SDK
go get -u github.com/okx/go-wallet-sdk/coins/bitcoin

⚙️ Build and Test

To build and test all blockchain modules, use the build.sh script located in the project root. This script iterates through each chain module under the coins directory, runs go mod tidy to clean dependencies, executes tests, and verifies successful builds.

sh build.sh

The output will display the build status for each chain. If a module fails, the error message will indicate the issue for further debugging.
