Ed25519.fromSeed

Derives an Ed25519 private key from a seed.

The seed must contain at least 32 bytes of cryptographically strong key material. Do not pass a password directly; use a password KDF first.

The permanent derivation contract uses the seed as the HMAC-SHA256 key. The HMAC message uses the ox.ed25519.fromSeed.v1 domain followed by a 32-bit big-endian counter set to zero.
