Case summary
What happened
On 2023-11-22, GRAIL/USD pricing used by a Silo Arbitrum market deviated after anomalous HTX trading data entered DIA's feed. Three users became insolvent and were liquidated, with Silo governance reporting roughly USD 21,000 in liquidation losses/fees. DIA removed HTX as a source and tightened deviation controls. A later proposal to compensate the affected users in SILO tokens was defeated. Silo continued operating and Silo v3 remained live in 2026.
Customer result
Customer outcome
Unknown
Silo governance discussed compensating the three affected users with SILO tokens, but the proposal was defeated. CYA therefore does not record realized compensation or a recovery percentage. The incident did not establish a protocol-wide claims process.

Asset treatment
Terms risk
Customer-owned
Silo is modeled as non-custodial smart-contract lending rather than a platform-owned account balance. The November 2023 event demonstrates third-party oracle and liquidation risk in isolated lending markets; non-custodial architecture does not remove those economic risks or guarantee compensation for oracle-driven liquidations.

Uncertainty
The roughly USD 21,000 figure is the governance post's estimate of losses associated with the three liquidations, not a protocol-wide bad-debt figure. The defeated compensation proposal is not treated as realized recovery.
Chronology
Historical record
Silo GRAIL oracle deviation liquidates three users
The DIA GRAIL/USD feed used by a Silo Arbitrum market incorporated anomalous HTX trading data during a broader exchange incident, causing the reported price to deviate materially from the perceived market value. Three users became insolvent and were liquidated. Silo governance estimated roughly USD 21,000 in losses associated with the liquidations. DIA removed HTX as a source and tightened deviation thresholds after the incident.
This is an oracle-data incident, not evidence of a protocol-wide exploit or insolvency. The approximately USD 21,000 figure is not represented as protocol bad debt.
