ERC-777/1155/721 hook without reentrancy guard

SUNSwap (sun.io)'s assessment for RD-F-015 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

AMM core (V2/V3/V4) operates on TRC-20 tokens (ERC-20 equivalent). No ERC-777/1155/721 callback integration found. TRC-20 does not natively support ERC-777 callbacks on TRON. V2 lock mutex mitigates reentrancy regardless.
