ERC-777/1155/721 hook without reentrancy guard

Across Protocol'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 #

Across handles ERC-20 tokens (WETH, USDC, etc.) via standard cross-chain bridge flows. No ERC-777 or ERC-1155 hook integration identified in core HubPool/SpokePool contracts. SwapAndBridge could in principle route through ERC-777 tokens but the nonReentrant guard on the SpokePool base would protect state. No OZ finding in this area.
