## Summary - Companion to EIP-8164 (Native Key Delegation for EOAs) - Modifies …the ECRECOVER precompile (address `0x01`) to be native-key-aware - **ECDSA guard**: after successful recovery, returns empty if the recovered address has a native-key delegation (`0xef01` + nonzero byte), preventing contracts from accepting signatures from dead ECDSA keys - **Native-key verification mode**: `0xff` sentinel in the `v` position enables contract-level signature verification for native-key accounts (ML-DSA-44 defined, forward-compatible with future schemes) - Gas model accounts for EIP-2929 warm/cold access and scheme-specific verification costs ## Notes - EIP number is `XXXX` (placeholder) — needs editor assignment - `discussions-to` URL is a placeholder — Ethereum Magicians thread TBD - Filename will need to be renamed to match assigned number 🤖 Generated with [Claude Code](https://claude.com/claude-code)
