signHash abstract method

Future<Uint8List> signHash(
  1. Uint8List hash
)

Signs a raw hash directly without any prefix.

Use this for:

  • ERC-4337 UserOperation signing (userOpHash is already a 32-byte hash)
  • Any case where you need to sign a pre-computed hash

WARNING: The hash should be exactly 32 bytes. This method does NOT add any prefix (unlike signMessage which adds EIP-191 prefix).

Implementation

Future<Uint8List> signHash(Uint8List hash);
