Web3 This Then That

A simple python app to watch the blockchain and take actions when things happen.

Development

Build the app:

python3.10 -m venv venv
. venv/bin/activate
pip install --upgrade pip wheel -c ./requirements-dev.txt
pip install -r requirements-dev.txt
ape plugins install .

Update requirements:

pip-compile -U --output-file requirements-dev.txt --resolver=backtracking ./requirements-dev.in ./requirements.in
# and then probably run: `pip install -r requirements-dev.txt`

pip-compile -U --resolver=backtracking ./requirements.in
# and then maybe run: `pip install -r requirements.txt`

Build a docker image:

docker build -t llamanodes/web3-this-then-that .
# TODO: push to ECR?

Run a docker image:

# TODO: example docker-compose
docker run \
    --rm -it \
    --env LLAMA_RPC_KEY="your ulid from <https://llamanodes.com/dashboard>" \
    --volume ~/.ape:/llama/.ape \
    --volume ~/.tokenlists:/llama/.tokenlists \
    llamanodes/web3-this-then-that

Open an interactive shell inside docker:

docker run \
    --rm -it \
    --entrypoint bash \
    --env LLAMA_RPC_KEY="your ulid from <https://llamanodes.com/dashboard>" \
    --volume ~/.ape:/llama/.ape \
    --volume ~/.tokenlists:/llama/.tokenlists \
    llamanodes/web3-this-then-that

Inside the interactive shell, you can use silverback:

silverback run "entrypoint:app" --network ethereum
silverback run "entrypoint:app" --network polygon

Likely useful environment variables:

SILVERBACK_BROKER_CLASS="taskiq:InMemoryBroker"
SILVERBACK_ENABLE_METRICS="True"
