@latticexyz/faucet

A minimal Typescript faucet to drip native tokens on Ethereum chains

Usage

1. Specify the environment variables. Note that you need to export these variables for the faucet service to get them.

   Variable	Description	Default
   HOST	Host that the indexer server listens on	0.0.0.0
   PORT	Port that the indexer server listens on	3002
   RPC_HTTP_URL1	HTTP URL for Ethereum RPC
   FAUCET_PRIVATE_KEY	Private key of wallet to distribute faucet funds from
   DRIP_AMOUNT_ETHER	Drip amount in ether

   (1) If you use http://localhost:8545 and it fails try using http://127.0.0.1:8545 instead

2. Start the server.

   npx @latticexyz/faucet
   

   For example, you can use these values to drip 1 ETH for a local anvil instance:

   Variable	Value	Comments
   RPC_HTTP_URL	http://127.0.0.1:8545	localhost sometimes doesn't work
   FAUCET_PRIVATE_KEY	0x59c6995e998f97a5a0044966f0945389dc9e86dae88c7a8412f4603b6b78690d	One of the default accounts
   DRIP_AMOUNT_ETHER	1

Getting ETH from a faucet

This sample program shows how to obtain ETH from a faucet using TypeScript.

Alternatively, you can submit a POST request to the faucet. For example, if you use the default HOST and PORT, this command requests a drip to the zero address.

curl -X POST http://127.0.0.1:3002/trpc/drip \
   -H "Content-Type: application/json" \
   -d '{"address": "0x0000000000000000000000000000000000000000"}'
