test: replace ganache with anvil (#1286)
* ci: install anvil

* test: use anvil instead of ganache

* ci: fix anvil ver

* ci: re-enable example tests

* test: remove unnecessary assertions

* test: enable anvil launch test

* docs: typo

* test: fix anvil chain id

* ci: install ganache

Ganache is needed for the Ganache tests

* chore: remove legacy feature from some examples

* ci: correctly build examples

* test: use correct account balance for anvil

* chore: remove sub_id == 1 check

this was only possible in ganache because it gives serial
sub ids, but in every other reasonable client the ids are generated
randomly, so we cannot test for its value

* test: ensure txs are different

There is a bug in Ganache's mempool which accepts duplicate transactions (here with the same nonce), whereas here we pre-set all the nonces so that they end up having a different transaction hash.

* test: ignore ganache tests

* fix: terzor api changes

* ci(examples): install Anvil, remove geth/ganache

* test(provider): Anvil instead of Geth

some tests start to fail now

* fix: revert usage of Anvil in ipc tests

Anvil does not support IPC yet

* fix: update examples script

* ci: use anvil for wasm example

* replace last ganache usage

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.
