feat(core): expose genesis and private key in Geth (#2091)
* feat(core): expose genesis and private key in Geth

 * expose the genesis and clique_private_key fields in GethInstance
 * add tests which initialize geth with clique_private_key, making sure
   the genesis and clique_private_key fields are exposed on the
   GethInstance

* add clique p2p port test

* refactor tests to clean up properly

README.md

Ethereum 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

Signing an ethereum-prefixed message

Signing in Ethereum is done by first prefixing the message with "\x19Ethereum Signed Message:\n" + message.length, and then signing the hash of the result.

# async fn foo() -> Result<(), Box<dyn std::error::Error>> {
use ethers::signers::{Signer, LocalWallet};

let message = "Some data";
let wallet = LocalWallet::new(&mut rand::thread_rng());

// Sign the message
let signature = wallet.sign_message(message).await?;

// Recover the signer from the message
let recovered = signature.recover(message)?;

assert_eq!(recovered, wallet.address());
# Ok(())
# }

Utilities

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

Features

  • ["eip712"] | Provides Eip712 trait for EIP-712 encoding of typed data for derived structs

ABI Encoding and Decoding

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