Interface that verifies provided signature for the data
Developer note: Interface defined by EIP-1271
function isValidSignature(bytes32 hash, bytes signature) external view returns (bytes4 magicValue) view external
Returns whether the provided signature is valid for the provided data Developer note: MUST return the bytes4 magic value 0x1626ba7e when function passes. MUST NOT modify state (using STATICCALL for solc < 0.5, view modifier for solc > 0.5). MUST allow external calls.
