Ethermint Faucet

NOTE: this repo was archived, the new version is using my evmosgrpc lib and a simple FASTAPI app.

Faucet server for Ethermint

How to use

The faucet is authenticated using Auth0 and the SPA with API architecture. A good example of this setup is the Ethermint faucet frontend.

Users have rate-limited access to the faucet with a configurable wait period. If the manage:faucet permission is given to a user in Auth0, additional endpoints are accessible to view transaction and user history, and manage a list of blocked addresses.

This faucet is configured to work with Ethermint.
