The faucet is a web application with the goal of distributing small amounts of Ether in private and test networks.
- 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
- Go (1.17 or later)
- Node.js
- Clone the repository and navigate to the app’s directory
git clone https://github.com/chainflag/eth-faucet.git
cd eth-faucet
- Bundle Frontend web with Vite
go generate
- Build Go project
go build -o eth-faucet
Use private key to fund users
./eth-faucet -httpport 8080 -wallet.provider http://localhost:8545 -wallet.privkey privkey
Use keystore to fund users
./eth-faucet -httpport 8080 -wallet.provider http://localhost:8545 -wallet.keyjson keystore -wallet.keypass password.txt
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:
./eth-faucet -httpport 8080
