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 to a single hardcoded oracle — caught only after 181 borrowers were liquidated. Every failure would have been visible to a multi-oracle cross-check in the same block. None had one watching. Until now.
Three oracles. One block.
