Unit0 examples

Setup for development

  • nix: nix develop
  • other Linux and macOS: ./dev-setup.sh; source .venv/bin/activate

Glossary

  • CL - Consensus Layer, Waves;
  • EL - Execution Layer, Ethereum.

Usage

Run any command without parameters to see the full list of options.

Transfer from CL to EL

u0-transfer-c2e

Transfer from EL to CL

u0-transfer-e2c

If you transfer a native token (Unit0), then you don't need to approve transfers for it. Otherwise, run approve command before transferring assets.

Approve transfers from the Standard Bridge

You have to do this for registered asset transfers.

u0-erc20-approve

Prepare chain_contract.withdraw transaction from EL transfer transaction hash

In case if a transfer failed during the process. You will need an EL transaction with a transfer from the logs and specify it in --txn-hash parameter.

u0-transfer-e2c-withdraw --txn-hash <Ethereum transaction hash in HEX>

Convenient way to provide arguments for commands

Instead of providing arguments, you can write a JSON file and load arguments from it using --args path/to/args.json.

Here is an example for consensus client local-network:

{
  "waves_private_key": "DwPvPGEp3LPg5gVRz7Pqd8mHa6dWK9dXtP4XDmKTz6ga",
  "eth_private_key": "0x8f2a55949038a9610f50fb23b5883af3b4ecb3c3bb792cbcefbd1542c692be63",
  "network_settings": {
    "name": "LocalNet",
    "cl_chain_id_str": "D",
    "cl_node_api_url": "http://127.0.0.1:16869",
    "el_node_api_url": "http://127.0.0.1:18545",
    "chain_contract_address": "3FXDd4LoxxqVLfMk8M25f8CQvfCtGMyiXV1"
  },
  "asset_name": "TestToken"
}

See all available options in ArgsData.

CLI arguments has precedence over JSON arguments.

Logging

You can configure the logging with a custom logging.conf (docs).

The precedence (from higher to lower) of config files:

  1. A path to the logging.conf file in the LOGGING_CONFIG environment variable.
  2. The logging.conf file in the current working directory.
  3. The default logging.conf file in the unit0-examples package.
