Crate cbrzn_ethers_core
source ·Expand description
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.
ⓘ
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());
Utilities

ganache-cli
via the GanacheBuilder
struct.
