Dependency graph (protocols depended upon)
Symbiotic's assessment for RD-F-050 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.
Evidence summary #
Dependency graph: Symbiotic holds ERC-20 collateral issued by external LST protocols (wstETH/Lido dominant, cbETH/Coinbase, rETH/RocketPool, wBETH/Binance, sUSDe/Ethena). wstETH_Burner.sol calls Lido WITHDRAWAL_QUEUE for ETH settlement of slashed wstETH. Failure of Lido (or any LST issuer) impairs the corresponding collateral pool at face value — no repricing or halt mechanism exists. Lido withdrawal queue disruption delays settlement but does not block vault accounting. This is a non-redundant critical dependency with no fallback repricing mechanism. Yellow (not red) because no documented prior failure of these specific dependencies has occurred.
