https://github.com/code-423n4/2023-10-ethena/blob/main/contracts/USDeSilo.sol#L12
The USDeSilo contract lacks the implementation of the supportsInterface(bytes4) function, a standard requirement specified by ERC-165. This omission could potentially hinder interoperability with other contracts and applications that rely on this interface detection mechanism. Without this function, external contracts may face challenges in determining the capabilities of the USDeSilo contract, leading to limited integration possibilities.
Output form slither:
# Check USDeSilo ## Check functions [ ] supportsInterface(bytes4) is missing
VS Code, Slither
To resolve this issue, the contract owner should implement the supportsInterface(bytes4) function as per the ERC-165 standard. The function should return true for the ERC-165 interface identifier and any other relevant interfaces used by the contract, such as ERC-20 and other custom interfaces. By implementing this function, the contract will comply with the ERC-165 standard, ensuring seamless integration and interaction with other Ethereum contracts and applications.
