ERC-777/1155/721 hook without reentrancy guard
GMX v2 (GMX Synthetics)'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 #
GMX v2 explicitly excludes ERC-777 and other callback tokens via the whitelist mechanism. GMX known issues page states: 'tokens with callbacks (e.g. ERC-777 tokens) are not compatible with the system and should not be whitelisted.' No ERC-777/1155/721 callback integration path is intended, and the known-issues documentation confirms this explicitly.
