Go SDK#

Overview#

Go-wallet-sdk is a wallet solution based on Go language that includes various public chains' different cryptographic algorithms and common functionalities. You can use it for creating private keys, addresses, assembling transactions, and performing signatures, among other things. This document will provide a detailed guide on how to use this SDK. Currently, it supports various mainstream blockchains, with each token format having its own independent module implementation. We will continue to add support for more blockchains in the future.

Supported platforms#

As a Go SDK, it can be easily integrated into Web applications, mobile applications, or desktop applications.

Installation and building#

Go GET#

To use the SDK, you first need to install it. You can use go get to get the latest version.

Our SDK supports two types of packages: public packages and single coin modules.

Public packages are for all currencies:

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

Integration of individual currencies, taking ETH and BTC as examples:

Integration of ETH:

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

Integration of BTC:

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

Main features#

Here is a specific introduction to the functions of each module in the SDK.

• crypto: This module provides commonly used security encryption algorithms and signature algorithms, etc.
• coins: This module implements methods for building and signing transactions for each coin. Each coin has a corresponding module, such as ethereum, bitcoin, etc. These modules provide transaction building and signing methods for specific coins.

Packages#

crypto#

This is a library that includes implementations of commonly used security encryption and signature algorithms such as BIP32, BIP39, ECDSA, ED25519, etc. For example:

• Common BIP32 functions: These functions are mainly used to handle and operate tasks related to the Bitcoin Improvement Payment Protocol (BIP32).
• BIP39 mnemonic generation, public/private key, and message signing functions: These functions are mainly used to handle and operate tasks related to the Bitcoin Improvement Payment Protocol (BIP39), such as generating mnemonics, public/private keys, and signing messages.
• Common hash and encoding/decoding functions: These functions are mainly used to handle common hash and encoding/decoding tasks, such as SHA256 hashing, Base64 encoding/decoding, etc.
• Common ED5519 signature functions: These functions are mainly used to handle and operate tasks related to the ED5519 signature algorithm.
