Nine oracle failures. Zero retail watchdogs.
Over the past 18 months, at least nine oracle-composition or hardcoded-oracle failures have caused ≥$50M in losses across Base-adjacent DeFi. Moonwell's cbETH market lost $2.68M — caught only after ~181 borrowers were liquidated. Composition-class oracle errors are detectable in seconds when independent feeds disagree; no free, RWA-tuned, hosted service was watching. Until now.
Three oracles. One block.
