WaaS Go Client Library

This repository contains the Protocol Buffer definitions for the Coinbase Wallet-as-a-Service (WaaS) APIs, as well as the Go client libraries generated from them.

Overview

WaaS is Coinbase's suite of cloud APIs for creating, managing, and using Multi-Party Computation (MPC)-based crypto wallets. Designed for use by nimble start-ups and large enterprise clients alike, WaaS APIs are self-service and composable, allowing developers to easily create applications that interact with the blockchain and inherit the maximal security properties of MPC-based key management.

Documentation

For full documentation, refer to docs.cloud.coinbase.com/waas.

For APIs that require multi-party computation (MPC), refer to the WaaS SDK repository.

Prerequisites

Repository Structure

  • auth/ contains the authentication-related code for accessing WaaS APIs.
  • clients/ contains client instantiation helpers for WaaS APIs.
  • gen/ contains Go code generated from the Protocol Buffers.
  • protos/ contains the Protocol Buffers that define the WaaS APIs.

Module Installation

go get github.com/coinbase/waas-client-library-go

Get Started

To test that your API Key gives you access as expected to the WaaS APIs:

  1. Replace apiKeyName and privKeyTemplate in example.go with your API Key information.
  2. Run go build.
  3. Run ./waas-client-library-go.
  4. You should see output like the following:
