Metronome reports $15.7 million synth backing gap and points to oracle lag in swap module
MetronomeDAO said about 6,367 msETH and 4.57 million msUSD in circulation are not backed by collateral, leaving a gap worth roughly $15.7 million at current prices. In a July 30 post-mortem, the protocol said trading bots spent months exploiting delayed price updates in its swap module, buying whichever synth was mispriced by stale Chainlink ETH/USD data. The shortfall represents about 31% of all msETH and 16% of all msUSD outstanding, and Metronome said any realized losses would fall on liquidity providers in pools on venues such as Curve and Aerodrome. The team said the issue is limited to the swap module, while its Morpho lending markets, MetBasis product, and core minting system continue to operate normally. Metronome has raised synth swap fees to suppress volume, built treasury-backed defensive positions, and said a roughly 30% drop in msETH or msUSD would make those positions profitable enough to buy back and burn all unbacked tokens. If prices do not fall that far, the protocol said interest from more than $51 million in outstanding debt will be used for gradual buybacks until full backing is restored.
