 ### How to Detect if a Contract Implements ERC-165
 
-1. The source contact makes a `STATICCALL` to the destination address with input data: `0x01ffc9a701ffc9a700000000000000000000000000000000000000000000000000000000` and gas 30,000. This corresponds to `contract.supportsInterface(0x01ffc9a7)`.

 2. If the call fails or return false, the destination contract does not implement ERC-165.
 3. If the call returns true, a second call is made with input data `0x01ffc9a7ffffffff00000000000000000000000000000000000000000000000000000000`.
 4. If the second call fails or returns true, the destination contract does not implement ERC-165.
