First-depositor / share-inflation guard

Pendle Finance's assessment for RD-F-075 — scored yellow on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

LP market layer: first-depositor guard exists via MINIMUM_LIQUIDITY = 1000 LP tokens locked in MarketMathCore.sol at first deposit (Uniswap-V2 dead-shares pattern). SY wrapper layer: MINIMUM_LIQUIDITY is also added to protocol reserves to protect against front-running the initial deposit per MixBytes analysis. However, there are hundreds of individual SY wrapper contracts across 6+ chains and factory versions V3-V6. Full verification that every deployed SY wrapper uniformly implements this guard was not achievable from available evidence. Some older (V3) or long-tail SY wrappers may have weaker protection. Yellow due to coverage uncertainty — not due to a confirmed absent guard.

Determine whether the vault has a first-depositor guard (seed deposit on deploy, virtual-share offset, or floor-check).
