Go Wasabi RPC Client

Implementation of a client for interacting with WasabiWallet via RPC in the Go programming language.

You can use this client to interact with WasabiWallet via RPC. The current version of the client supports all methods used in WasabiWallet in the main repository branch. This means that some methods are not yet available in the current wallet release and are partially absent from the RPC documentation on the WasabiWallet website.

The client can be used with WasabiWallet, both when running in GUI mode and as a headless daemon.

Links to WasabiWallet resources:

• Website
• Wallet repository on GitHub
• Documentation repository¹
• RPC documentation²

¹ - WasabiWallet documentation on GitHub contains documentation for all RPC methods, including those not yet available in the wallet release. Such methods are described in the pull requests section. You can find documentation for these methods by searching the repository. ² - RPC documentation on the WasabiWallet website contains documentation only for methods available in the current wallet release.

Installing WasabiWallet.

Option 1: Installing the wallet from the current release:

• Link to download the GUI wallet
• Instructions for running the wallet as a headless daemon

Option 2: Building the wallet from source and running as a headless daemon in a Docker container under debian:bookworm-20240211:

# Dockerfile for wasabi-wallet

FROM debian:bookworm-20240211 AS wallet

    && cd WalletWasabi \
    && git checkout $COMMIT_HASH 

RUN cd /WalletWasabi/WalletWasabi.Fluent.Desktop && dotnet build && rm -rf ~/.nuget ~/.local

WORKDIR /WalletWasabi/WalletWasabi.Daemon

CMD ["dotnet", "run", "--jsonrpcserverenabled=true", "--enablegpu=false", "--datadir=\"/wasabi/data\"", "--network=testnet"]

Detailed information about wallet startup parameters is available here.

Building the image and running the container with the wallet:

docker build --target wallet -t wasabi_wallet .

docker run -d -p 37128:37128/tcp --name wasabi_container wasabi_wallet

Check the wallet logs:

docker logs -f wasabi_container

Using our client.

Downloading the client:

go get -u github.com/acfnv/go-wasabi-rpc-client

Example of usage:

package main

import (
	"flag"
	"fmt"
	"log"
	"net/http"
	"time"
	
	"github.com/acfnv/go-wasabi-rpc-client"
)

var (
	rpcHost     = flag.String("rpc_host", "127.0.0.1", "Host of the wasabi rpc server.")
	rpcPort     = flag.Int("rpc_port", 37128, "Port of the wasabi rpc server.")
)

func main() {
	flag.Parse()
	
	// Define the configuration for the RPC client.
	config := wasabi.Config{
		Host: *rpcHost,
		Port: *rpcPort,
	}
	
	// Create a new RPC client.
	client, err := wasabi.NewClient(config)
	if err != nil {
		return nil, err
	}
	
	// Check the availability of the RPC server.
	for {
		if client.IsWasabiWalletUp() {
			break
		}
		time.Sleep(1 * time.Second)
	}
	log.Printf("WasabiWallet RPC Server started")
	
	// Making a request to the RPC server.
	resp, err := client.GetStatus()
	if err != nil {
		return err
	}
	log.Printf("WasabiWallet RPC Server status: %v", resp)
	
	// ...
}
