// This script snapshots the bytecode and ABI for the `hardhat/common-contracts.js` script.
|
|
// - Bytecode is fetched directly from the blockchain by querying the provided client endpoint. If no endpoint is
|
|
// provided, ethers default provider is used instead.
|
|
// - ABI is fetched from etherscan's API using the provided etherscan API key. If no API key is provided, ABI will not
|
|
// be fetched and saved.
|
|
//
|
|
// The produced artifacts are stored in the `output` folder ('test/bin' by default). For each contract, two files are
|
|
// produced:
|
|
// - `<name>.bytecode` containing the contract bytecode (in binary encoding)
|
|
// - `<name>.abi` containing the ABI (in utf-8 encoding)
