DVT-operator sidecar

DVT-Sidecar is a service which should be running on each DVT operator in DVT cluster. Works in conjuction with DVT-relayer.

DVT sidecar:

1. Loads DV keystores
2. Polls validator exits from Relayer
3. Pushes exit signature shares to Relayer on behalf of DVT operators.

Setup

1. Install poetry
2. poetry install
3. cp .env.example .env
4. Fill .env file with appropriate values

Run

1. poetry shell
2. export PYTHONPATH=.
3. python src/app.py

Testing

This section is about integration testing, when sidecar works in conjunction with DVT Relayer and Stakewise Operator.

Running the whole cluster of DVT sidecars locally may be cumbersome. For testing purpose single sidecar may work on behalf of several DVT operators. So there are 2 ways to initialize environment: one for production and another one for testing.

Example of production setup for Obol:

OBOL_KEYSTORES_DIR_TEMPLATE=node0/validator_keys
OBOL_NODE_INDEX=0

In testing setup you can parametrize keystores path so that single sidecar will be using multiple keystores:

OBOL_KEYSTORES_DIR_TEMPLATE=node{node_index}/validator_keys
OBOL_NODE_INDEXES=0,1,2,3

Example of production setup for SSV:

SSV_OPERATOR_KEY_FILE=encrypted_private_key.json
SSV_OPERATOR_PASSWORD_FILE=password.txt
SSV_OPERATOR_ID=123

In testing setup you can parametrize SSV operator key path. So that sidecar will be acting on behalf of multiple SSV operators.

SSV_OPERATOR_KEY_FILE_TEMPLATE=operator-{operator_id}/encrypted_private_key.json
SSV_OPERATOR_PASSWORD_FILE_TEMPLATE=operator-{operator_id}/password.txt
SSV_OPERATOR_IDS=123,456
