eth.zig

FAQ

Frequently asked questions about eth.zig.

Is eth.zig production-ready?

eth.zig is at v0.2.2. All listed features are complete and tested, but the library is young. It's suitable for infrastructure projects, bots, and tools. Evaluate for your risk tolerance before using in high-value production systems.

What Zig version do I need?

Zig >= 0.15.2. The library tracks Zig stable releases and is also tested against nightly builds in CI.

How does secp256k1 signing compare to alloy.rs?

eth.zig wins on secp256k1 signing -- 2.34x faster than alloy.rs for signing and 4.23x faster for sign+recover (measured 2026-06-10 against alloy-primitives 1.6 / alloy 2.0).

eth.zig wins 18 of 26 benchmarks overall. alloy.rs wins on address hex parsing (1.55x, SIMD), hex encoding (1.08x), UniswapV4 swap (1.07x), and Keccak-256 at 256B/1KB inputs (within ~2%).

Does eth.zig support all Ethereum transaction types?

Yes:

  • Legacy (Type 0) -- pre-EIP-1559
  • EIP-2930 (Type 1) -- access lists
  • EIP-1559 (Type 2) -- priority fees
  • EIP-4844 (Type 3) -- blob transactions

EIP-7702 transactions are planned.

Which chains are supported?

eth.zig includes chain definitions for:

  • Ethereum (mainnet + Sepolia + Holesky)
  • Arbitrum (One + Sepolia)
  • Optimism (mainnet + Sepolia)
  • Base (mainnet + Sepolia)
  • Polygon (mainnet + Amoy)

Any EVM-compatible chain works -- these are just convenience configurations.

Can I use eth.zig for MEV / HFT?

Yes, that's a primary use case. eth.zig beats alloy.rs on 18/26 benchmarks (alloy 1.6/2.0, run 2026-06-10), with the biggest wins in RLP transaction encoding (24.33x), ABI decoding (8.41x), secp256k1 sign+recover (4.23x), secp256k1 signing (2.34x), u256 division (3.43x), and mulDiv (1.82x), plus comptime selectors (zero-cost at runtime).
