Use the Safe ERC-20 Library

When working with third-party ERC20 tokens, using the SafeERC20 library is crucial to avoid common pitfalls. Functions like safeTransfer and safeApprove include additional safety checks that standard ERC20 functions often lack.

For example, SafeERC20 ensures that the target address is a contract, not an externally owned account (EOA), preventing unintended interactions with non-contract addresses. It also addresses issues with non-standard tokens that may return false instead of reverting on failure.
