faucet-testnet

The faucet is a web application with the goal of distributing small amounts of Ether in private and test networks.

Features

• Allow to configure the funding account via private key or keystore
• Asynchronous processing Txs to achieve parallel execution of user requests
• Rate limiting by ETH address and IP address as a precaution against spam
• Prevent X-Forwarded-For spoofing by specifying the count of reverse proxies

Get started

Prerequisites

• Go (1.16 or later)
• Node.js >= 16.15

Installation

1. Clone the repository and navigate to the app’s directory

git clone https://github.com/haqq-network/faucet-testnet.git
cd faucet-testnet

1. Bundle Frontend web with Rollup

npm run build

1. Build Go project

go build -o faucet-testnet

Usage

Use private key to fund users

./faucet-testnet -httpport 8080 -wallet.provider http://localhost:8545 -wallet.privkey privkey

Use keystore to fund users

./faucet-testnet -httpport 8080 -wallet.provider http://localhost:8545 -wallet.keyjson keystore -wallet.keypass password.txt

Configuration

You can configure the funder by using environment variables instead of command-line flags as follows:

export WEB3_PROVIDER=rpc endpoint
export PRIVATE_KEY=hex private key

or

export WEB3_PROVIDER=rpc endpoint
export KEYSTORE=keystore path
echo "your keystore password" > `pwd`/password.txt

Then run the faucet application without the wallet command-line flags:

./faucet-testnet -httpport 8080

Optional Flags

The following are the available command-line flags(excluding above wallet flags):

Flag	Description	Default Value
-httpport	Listener port to serve HTTP connection	8080
-proxycount	Count of reverse proxies in front of the server	0
-queuecap	Maximum transactions waiting to be sent	100
-faucet.amount	Number of Ethers to transfer per user request	1
-faucet.minutes	Number of minutes to wait between funding rounds	1440
-faucet.name	Network name to display on the frontend	testnet

Docker deployment

docker run -d -p 8080:8080 -e WEB3_PROVIDER=rpc endpoint -e PRIVATE_KEY=hex private key haqq-network/faucet-testnet:1.1.0

or

docker run -d -p 8080:8080 -e WEB3_PROVIDER=rpc endpoint -e KEYSTORE=keystore path -v `pwd`/keystore:/app/keystore -v `pwd`/password.txt:/app/password.txt haqq-network/faucet-testnet:1.1.0
