Go library providing an abstraction to Starknet nodes.

This library is under development; expect APIs and data structures to change until it reaches version 1.0. In addition, clients' implementations of both their own and the standard API are themselves under development so implementation of the the full API can be incomplete.

Table of Contents

Install

go-starknet-client is a standard Go module which can be installed with:

go get github.com/attestantio/go-starknet-client

Support

go-starknet-client supports execution nodes that comply with the standard execution node API.

Usage

Please read the Go documentation for this library for interface information.

Example

Below is a complete annotated example to access an execution node.

package main

import (
    "context"
    "fmt"

    execclient "github.com/attestantio/go-starknet-client"
    "github.com/attestantio/go-starknet-client/jsonrpc"
    "github.com/rs/zerolog"
)

func main() {
    // Provide a cancellable context to the creation function.
    ctx, cancel := context.WithCancel(context.Background())
    client, err := jsonrpc.New(ctx,
        // WithAddress supplies the address of the execution node, as a URL.
        jsonrpc.WithAddress("http://localhost:8545/"),
        // LogLevel supplies the level of logging to carry out.
        jsonrpc.WithLogLevel(zerolog.WarnLevel),
    )
    if err != nil {
        panic(err)
    }

    fmt.Printf("Connected to %s\n", client.Name())

    blockNumber, err := provider.BlockNumber(ctx)
    if err != nil {
        panic(err)
    }
    fmt.Printf("Current block number is %v\n", blockNumber)

    // Cancelling the context passed to New() frees up resources held by the
    // client, closes connections, clears handlers, etc.
    cancel()
}
