Use of assembly function
Summary
Assembly function in Solidity omits several security features of the language, therefore it is very error-prone.
PoC: https://github.com/ArkProjectNFTs/bridge/blob/main/apps/blockchain/ethereum/src/Bridge.sol#L327
Recommendations
Avoid using the function, unless it is necessary, and you know how to use it.
