Hi @ilanD,
Sorry, I don’t know which public tokens require SafeERC20.
You might need to check all the tokens that you wanted to support or use SafeERC20 to be on the safe side.
You could try Online ERC20 contract verifier to check.
Looking at https://etherscan.io/tokens I found a couple.
Contract TetherToken
https://etherscan.io/token/0xdac17f958d2ee523a2206206994597c13d831ec7
== ERC20 functions definition ==
[x] transfer (address, uint256) -> (bool)
[x] approve (address, uint256) -> (bool)
[x] transferFrom (address, address, uint256) -> (bool)
[✓] allowance (address, address) -> (uint256)
[✓] balanceOf (address) -> (uint256)
Contract BNB
https://etherscan.io/token/0xB8c77482e45F1F44dE1745F52C74426C631bDD52

[✓] approve (address, uint256) -> (bool)
[✓] transferFrom (address, address, uint256) -> (bool)
[x] allowance (address, address) -> (uint256)
