LP token balanceOf used for pricing

Pendle Finance's assessment for RD-F-061 — scored green on the v1.7.0 rubric. The evidence below is the curator's reasoning for this score.

Evidence summary #

Not found in Pendle oracle design. AMM TWAP accumulates from trade events (cumulative implied rate from AMM interactions), not from balanceOf of LP tokens. SY rates come from underlying protocol state calls. LP-token-balanceOf manipulation attack vector is not applicable to Pendle's AMM-accumulator design.

Methodology #

Determine whether protocol pricing is derived from the `balanceOf` of LP tokens in a contract (manipulable by direct token transfer / donation).
