Vulnerability details

Temple Gold tokens uses OFT LayerZero standard which allows users to use Temple Gold token on other chains. The protocol also decided that this token is going to be non-transferable. User can only transfer this token to the same address on other chains. Everything is okay for EOA addresses. However when the user uses other types of wallets or account abstraction it can lead to loss of funds for the user. His address on one chain is not always the same on the other chains.

Impact

While trying to bridge Temple Gold to other chains some users are exposed to risk of losing their tokens.

Recommended Mitigation Steps

There is no simple fix to this issue. One idea that I came up with is to check if the caller is an EOA address, however this creates a barrier for other users. Unfortunately I can not provide other solution to this problem.
