lux-crypto-evm256

Canonical Rust binding for Lux EVM 256-bit big-int math primitives:

• modexp (EIP-198 / 0x05 precompile)
• evm256_mulmod (EVM MULMOD opcode)
• evm256_addmod (EVM ADDMOD opcode)

Status: stub — c_modexp.cpp returns CRYPTO_ERR_NOTIMPL. Tests gated #[ignore]. Tracked at #modexp-c-abi-impl.

The implementations live in luxcpp/crypto/modexp/; the empty luxcpp/crypto/evm256/ directory is a placeholder for future kernel-side dispatch.
