Raiden Network Smart Contract specs
- Python 3.6
- https://pip.pypa.io/en/stable/
Recommended:
pip install raiden-contracts
We do not recommend the smart contracts to be used in production as of this moment. All contracts are WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. Use at your own risk.
If you want to use the officially deployed contracts, please use the raiden_contracts/data/contracts.json file to get the ABI and bytecode for initializing the contract instances.
You can find the addresses of the deployed contracts in raiden_contracts/constants.py, along with other useful constants that you can import.
If you are using the raiden-contracts package in your project, you can use:
from raiden_contracts.contract_manager import (
ContractManager,
contracts_precompiled_path,
)
from raiden_contracts.constants import (
CONTRACT_TOKEN_NETWORK_REGISTRY,
EVENT_TOKEN_NETWORK_CREATED,
)
manager = ContractManager(contracts_precompiled_path())
compiled_contract_data = manager.get_contract(CONTRACT_TOKEN_NETWORK_REGISTRY)
deployment_data = get_contracts_deployed(int(web3.version.network))
TOKEN_NETWORK_REGISTRY_ADDRESS = deployment_data['contracts'][CONTRACT_TOKEN_NETWORK_REGISTRY].address
# And then use:
# compiled_contract_data['abi']
# compiled_contract_data['bin']
# ROPSTEN_TOKEN_NETWORK_REGISTRY_ADDRESS
# to initialize the contract instance
All contracts under raiden_contracts/contracts/test/ are only for testing purposes and they should not be used in production.
If you want to test and further develop outside the officially provided source code, compiled files and deployed addresses, you can do it at your own risk.
If you want to install the package from source:
make install
To verify that the precompiled raiden_contracts/data/contracts.json file corresponds to the source code of the contracts:
make verify_contracts
For development and testing, you have to install additional dependencies:
pip install -r requirements-dev.txt
Make sure you have solc installed: https://solidity.readthedocs.io/en/latest/installing-solidity.html
make compile_contracts
# tests pytest pytest raiden_contracts/tests/test_token_network.py # Recommended for speed: pip install pytest-xdist==1.17.1 pytest -n NUM_OF_CPUs
If you are using the raiden-contracts package in your project, you can also test the source code directly (not only the precompiled contract data):
from raiden_contracts.contract_manager import (
ContractManager,
contracts_source_path,
)
manager = ContractManager(contracts_source_path())
Check deployment options:
python -m raiden_contracts.deploy --help
Deploying the main Raiden Network contracts with the raiden command:
python -m raiden_contracts.deploy raiden --rpc-provider http://127.0.0.1:8545 --private-key /path/to/your/private_key/file --gas-price 10 --gas-limit 6000000
Deploying a token for testing purposes (please DO NOT use this for production purposes) with the token command:
python -m raiden_contracts.deploy token --rpc-provider http://127.0.0.1:8545 --private-key /path/to/your/private_key/file --gas-price 10 --token-supply 10000000 --token-name TestToken --token-decimals 18 --token-symbol TTT
Registering a token with the TokenNetworkRegistry contract, so it can be used by the Raiden Network, with the register command:
python -m raiden_contracts.deploy register --rpc-provider http://127.0.0.1:8545 --private-key /path/to/your/private_key/file --gas-price 10 --token-address TOKEN_TO_BE_REGISTERED_ADDRESS --registry-address TOKEN_NETWORK_REGISTRY_ADDRESS
Deployment information is stored in a deployment_[CHAIN_NAME].json file corresponding to the chain on which it was deployed. To verify that the deployed contracts match the compiled data in contracts.json and also match the deployment information in the file, we can run:
python -m raiden_contracts.deploy verify --rpc-provider http://127.0.0.1:8545 # Based on the network id, the script verifies the corresponding deployment_[CHAIN_NAME].json file # using the chain name-id mapping from constants.py
