Ethereum Virtual Machine implementation

evmodin

Fast EVM implementation with support for resumability. Port of evmone to Rust.

Usage

use evmodin::{*, host::*, util::*, tracing::*};
use ethereum_types::*;
use hex_literal::hex;

let my_code = Bytecode::new()
    .mstore8_value(0, b'h')
    .mstore8_value(1, b'e')
    .mstore8_value(2, b'l')
    .mstore8_value(3, b'l')
    .mstore8_value(4, b'o')
    .ret(0, 5)
    .build();

let message = Message {
    kind: CallKind::Call,
    is_static: true,
    depth: 0,
    gas: 200,
    destination: Address::zero(),
    sender: Address::zero(),
    input_data: vec![].into(),
    value: U256::zero(),
};

assert_eq!(
    AnalyzedCode::analyze(my_code)
        .execute(&mut DummyHost, &mut NoopTracer, None, message, Revision::latest()),
    Output {
        status_code: StatusCode::Success,
        gas_left: 146,
        output_data: b"hello".to_vec().into(),
        create_address: None,
    }
)
