fix(core): set miner.etherbase in clique mode (#2210)
* fix(core): set miner.etherbase in clique mode

 * https://github.com/ethereum/go-ethereum/pull/26413 caused the default
   clique configuration for the GethInstance to fail to start, because
   we did not pass a `miner.etherbase` flag on startup
 * adds a `miner.etherbase` flag with the clique signer address as the
   argument

* use format str instead of to_string

* add comment on Debug

* update is_clique comment for miner.etherbase

* fix first etherbase flag

* cargo fmt

ethers-core

Ethereum data types, cryptography and utilities.

It is recommended to use the utils, types and abi re-exports instead of the core module to simplify your imports.

This library provides type definitions for Ethereum's main datatypes along with other utilities for interacting with the Ethereum ecosystem

For more information, please refer to the book.

Feature flags

  • eip712: Provides the Eip712 trait and derive procedural macro for EIP-712 encoding of typed data.

ABI

This crate re-exports the ethabi crate's functions under the abi module, as well as the secp256k1 and rand crates for convenience.

Utilities

The crate provides utilities for launching local Ethereum testnets by using ganache-cli via the GanacheBuilder struct.

Examples

Calculate the UniswapV2 pair address for two ERC20 tokens:

# use ethers_core::abi::{self, Token};
# use ethers_core::types::{Address, H256};
# use ethers_core::utils;
let factory: Address = "0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f".parse()?;

let token_a: Address = "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48".parse()?;
let token_b: Address = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2".parse()?;
let encoded = abi::encode_packed(&[Token::Address(token_a), Token::Address(token_b)])?;
let salt = utils::keccak256(encoded);

let init_code_hash: H256 = "0x96e8ac4277198ff8b6f785478aa9a39f403cb768dd02cbee326c3e7da348845f".parse()?;

let pair = utils::get_create2_address_from_hash(factory, salt, init_code_hash);
let weth_usdc = "0xB4e16d0168e52d35CaCD2c6185b44281Ec28C9Dc".parse()?;
assert_eq!(pair, weth_usdc);
# Ok::<(), Box<dyn std::error::Error>>(())
