Faucet-Py

A simple python implementation of an EVM compatible faucet.

Python API

Requirements

Python +3.x

Installation

cd api
python3 -m venv .venv
. .venv/bin/activate
pip3 install -r requirements-dev.txt

pip install setuptools

Run application

Check .env.example for reference.

cd api
python3 -m flask --app api run --port 8000

Run tests

cd api
python3 -m unittest discover -p 'test_*.py'

Run specific test case:

cd api
python3 -m unittest tests.test_api.TestAPI.test_ask_route_blocked_users

Run Flake8 and isort

cd api
python3 install -r requiremenets-dev.txt
isort **/*.py --atomic
python3 -m flake8

Operations

Add enabled tokens

To enable tokens on the API just run the command create_enabled_token. Accepted parameters: token name, chain ID, token address, maximum amount per day per user, whether native or erc20

Samples below:

cd /api
flask -A api create_enabled_token GNO 10200 0x19C653Da7c37c66208fbfbE8908A5051B57b4C70 0.01 erc20
flask -A api create_enabled_token xDAI 10200 0x0000000000000000000000000000000000000000 0.01 native

Once enabled, the token will appear in the list of enabled tokens on the endpoint api/v1/info.

Create access keys

To create access keys on the API just run the command create_access_keys. Accepted parameters: token name, chain ID, token address, maximum amount per day per user, whether native or erc20

Samples below:

cd /api
flask -A api create_access_keys

Change maximum daily amounts per user

If you want to change the amount you are giving out for a specific token, make sure you have sqlite installed on the server, e.g. apk update && apk add sqlite.

Enter the database: sqlite path/to/database

Search for the token to update: select chain_id, max_amount_day from tokens where name = 'xDAI' Update amount: update tokens set max_amount_day = 0.00015 where chain_id = 100;

ReactJS Frontend

Requirements

NodeJS v18.x

Installation

nvm use

cd app
yarn

Run application

cd app
yarn start

Docker Compose Up and create Access keys

If you do not reset the volume you will be able to reuse the sqlite database with latest data (access keys and enabled tokens)

docker-compose up --build -d

docker ps

docker exec -it <container_name_or_id> /bin/bash

docker exec -it <container_name_or_id> flask -A api create_access_keys

docker exec -it <container_name_or_id> flask -A api create_enabled_token xDAI 100 0x0000000000000000000000000000000000000000 0.01 native

docker logs -f <container_name_or_id>
