# Bridge Agents - Operators

The Grail bridge requires agents called operators.&#x20;

Operators monitor the bridge operations and assist users with deposits and withdrawals. They constantly monitor both the Bitcoin and rollup networks and participate in defined bridging protocol steps.&#x20;

A minimum of two operators are required to keep the bridge protocol going, but any number can be supported.&#x20;
