ERC-777/1155/721 hook without reentrancy guard

Orca's assessment for RD-F-015 — scored not_applicable on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

ERC-777/1155/721 are EVM token standards. Orca Whirlpools uses SPL Token and Token-2022 (Solana native standards). SPL Token does not have callback hooks analogous to ERC-777 tokensReceived. No ERC-777/1155/721 integration exists.

Methodology #

Determine whether the protocol integrates token standards with callbacks (ERC-777 tokensReceived, ERC-1155 onReceived, ERC-721 onReceived) without reentrancy guards on the affected functions.
