Module ethers::core [−][src]
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
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.
Modules
Pure Rust implementation of the secp256k1 (K-256) elliptic curve, including support for the Elliptic Curve Digital Signature Algorithm (ECDSA), Elliptic Curve Diffie-Hellman (ECDH), and general purpose elliptic curve/field arithmetic which can be used to implement protocols based on group operations.
Utilities for random number generation
Various utilities
