secp256k1 (vendored libsecp256k1 v0.8.0, recoverable ECDSA), BIP-39
mnemonics, BIP-32 derivation, Keccak-256, EIP-55 addresses and EIP-712
typed data hashing.
Client-side signing only: no RLP, no transaction construction, no chain
writes. The resolver path stays read-only.
Verified against published vectors — the 24 official BIP-39 English
vectors, BIP-32 spec vectors 1 and 2, the EIP-55 spec addresses and the
EIP-712 Mail example.
