Use Cryptographic Libraries

In Solidity, verifying signatures is a crucial part of ensuring that only authorized parties can perform specific actions in a smart contract. Instead of writing custom signature verification logic, developers should rely on well-established cryptography libraries.

These libraries have been thoroughly tested and are less likely to contain critical bugs that could lead to exploits, such as unauthorized access or fraudulent transactions. Issues around ecrecover, like signature malleability or improper error handling, as well as potential integration bugs with ERC-1271 signatures, are also addressed by these libraries.
