Ed25519Signature

data class Ed25519Signature(val publicKey: ByteArray, val signature: ByteArray) : SmartAccountSignature

Ed25519 signature from a traditional keypair.

Ed25519 signatures are 64 bytes and provide deterministic signing with strong side-channel resistance.

toScVal returns the raw 64-byte signature as SCValXdr.Bytes. The Ed25519 verifier contract expects BytesN<64> directly as sig_data. The corresponding public key is supplied separately from the smart account's on-chain External(verifier, key_data) storage and is NOT transmitted in the auth payload.

The publicKey field is retained on the data class for local Ed25519 signature verification before submission and for content-based equality.

Example:

val ed25519Sig = Ed25519Signature(
    publicKey = byteArrayOf(...),   // 32-byte Ed25519 public key
    signature = byteArrayOf(...)    // 64-byte Ed25519 signature
)
val scVal = ed25519Sig.toScVal()    // SCValXdr.Bytes holding the raw 64 bytes
