Low-level EVM ABI, hex, and RLP helpers used by runtime and collector crates.

This crate keeps encoding and decoding concerns separate from transport code so higher layers can assemble RPC requests, contract calls, and byte-oriented payloads without reimplementing Ethereum primitives.

Examples

use mfm_evm_core::abi::function_selector;
use mfm_evm_core::encoding::{encode_erc20_decimals, normalize_address};

let selector = function_selector("balanceOf", &["address".to_string()]);
assert_eq!(selector, [0x70, 0xa0, 0x82, 0x31]);
assert_eq!(encode_erc20_decimals(), "0x313ce567");
assert_eq!(
    normalize_address("0xAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA")?,
    "0xaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
);
