Module INonce 

Nonce interface for managing 2D nonces as per the Account Abstraction spec.

This precompile manages user nonce keys (1-N) while protocol nonces (key 0) are handled directly by account state. Each account can have multiple independent nonce sequences identified by a nonce key.

interface INonce {
    function getNonce(address account, uint256 nonceKey) external view returns (uint64 nonce);
    function getActiveNonceKeyCount(address account) external view returns (uint256 count);
    event NonceIncremented(address indexed account, uint256 indexed nonceKey, uint64 newNonce);
    event ActiveKeyCountChanged(address indexed account, uint256 newCount);
    error ProtocolNonceNotSupported();
    error InvalidNonceKey();
    error NonceOverflow();
}
