⚛️ Tendermint2 Faucet ⚛️

Overview

faucet is a versatile command-line interface (CLI) tool and library designed to effortlessly deploy a faucet server for Gno Tendermint 2 networks.

Key Features

Customizability

This faucet is highly customizable, allowing you to tailor it to the specific needs of your Tendermint 2 network. You can easily configure token types, distribution limits, and other parameters to suit your requirements.

Batch JSON Request Support

The faucet supports batch JSON requests, making it efficient for mass token distribution. You can submit multiple requests in a single batch, reducing the overhead of individual requests.

Extensibility

The faucet is designed with extensibility in mind. You can extend its functionality through middleware and custom handlers. This means you can integrate additional features or connect it to external systems seamlessly, like a rate limiting system.

Getting Started

As a binary

To get started with the Tendermint 2 Faucet, follow these steps:

1. Clone this repository to your local machine:

git clone github.com/gnolang/faucet

1. Build out the binary

To build out the binary, run the following command:

make build

1. Run the faucet

To run the faucet, start the built binary:

./build/faucet

It should print something like the following. (Note the port number at the end.)

2024-01-11T12:47:27.826+0100	INFO	cmd/logger.go:17	faucet started at [::]:8545

1. To send coins to a single account, in a new terminal enter the following (change to the correct recipient address):

curl --location --request POST 'http://localhost:8545' --header 'Content-Type: application/json' --data '{"To": "g1juz2yxmdsa6audkp6ep9vfv80c8p5u76e03vvh"}'

As a library

To add faucet to your Go project, simply run:

go get github.com/gnolang/faucet

To use the faucet, you can set it up as such:

package main

import (
	// ...
	"context"

	"github.com/gnolang/faucet/client/http"
	"github.com/gnolang/faucet/estimate/static"
)

func main() {
	// Create the faucet
	f, err := NewFaucet(
		static.New(...), // gas estimator
		http.NewClient(...), // remote address 
        )

	// The faucet is controlled through a top-level context
	ctx, cancelFn := context.WithCancel(context.Background())

	// Start the faucet
	go f.Serve(ctx)

	// Close the faucet
	cancelFn()
}

What kind of extensibility?

Middleware

Middleware functions can be added to extend the faucet's functionality. For example, you can add middleware to authenticate users, log requests, or implement rate limiting.

Custom Handlers

Custom request handlers can be created to handle specific actions or integrate with external systems. For instance, you can create a custom handler to trigger additional actions when tokens are distributed, such as sending notifications.
