get_linked_contract

Documentation for eth_defi.abi.get_linked_contract function.

get_linked_contract(web3, fname, hardhat_export_data=None)[source]

Create a Contract proxy class from our bundled contracts or filesystem and links it Solidity bytecode.

Needed when contracts contain references to libraries. The contract bytecode must be processed and placeholders must be replaced by the on-chain addresses of the deployed library contracts.

Example:

path = self.path.joinpath("artifacts/@aave/core-v3/contracts/mocks/tokens/MintableERC20.sol/MintableERC20.json")
return get_linked_contract(web3, path, get_aave_hardhard_export())

Note

If you do not need linking use get_contract() which is faster.

Parameters

web3 (web3.main.Web3) – Web3 instance
fname (str | pathlib.Path) –
Solidity compiler artifact.

Use slash prefixed path for absolute lookups.

JSON filename from supported contract lists.
hardhat_export_data (Optional[dict]) –
Hardhat deployment export data to link bytecode.

A JSON file generated by hardhat deploy –export command.

Returns

Contract proxy class

Return type

Type[web3.contract.contract.Contract]
