ethers-core
Ethereum data types, cryptography and utilities.
Warning
This library is in the process of being deprecated. See #2667 for more information.
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
: Does nothing.
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 ;
# use ;
# use utils;
let factory: Address = "0x5C69bEe701ef814a2B6a3EDD4B1652CB9cc5aA6f".parse?;
let token_a: Address = "0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48".parse?;
let token_b: Address = "0xC02aaA39b223FE8D0A0e5C4F27eAD9083C756Cc2".parse?;
let encoded = encode_packed?;
let salt = keccak256;
let init_code_hash: H256 = "0x96e8ac4277198ff8b6f785478aa9a39f403cb768dd02cbee326c3e7da348845f".parse?;
let pair = get_create2_address_from_hash;
