Flash loan and missing health check drained lending markets
A missing health check in donateToReserves() let an attacker create bad debt via flash loan, then self-liquidate with a controlled liquidator contract for $197M — most recovered.
Imported-record overview
These fields reproduce or normalize claims in an imported research record. “Reported” describes provenance; it does not mean ChainRadar has confirmed the claim.
Treat this as a reported explanation to test against code, traces, transaction data, and other primary evidence.
Date-free learning path
Synthetic study sequence for learning purposes; timestamps and ordering may not reproduce the full verified incident chronology. Synthetic dates are deliberately omitted below.

Teaching model
Educational reconstruction intended to explain the reported attack pattern, not a transaction-level evidentiary trace.
Follow the numbered arrows; loopbacks model repeated actions or repayments. Every label is derived from the imported flow actions and structure.
Values describe reported movement between stages. Repeated amounts are not additional losses.
| Step | From | To | Reported action | Value |
|---|---|---|---|---|
| 01 | Flash Loan | Attacker | Temporary Capital | $30000B |
| 02 | Attacker | Euler Market | Deposit And Borrow Loop | $195000B |
| 03 | Attacker | Euler Market | Donate To Reserve | $100000B |
| 04 | Euler Market | Attacker | Liquidation Payout | $197000B |
Imported indicators
Contract entries are reproduced from the local research archive. Confirm chain, bytecode, ownership, and incident relevance against primary evidence before using them in an investigation.

These imported mitigation labels are study prompts, not a complete or validated remediation plan. Test them against the protocol's actual architecture and failure mode.
Investigator workflow
Turn this background study into questions for a separate, evidence-led investigation. Never promote an educational edge or imported label into a finding without corroboration.
Preserve official disclosures, on-chain transactions, code, retrieval times, and other evidence supporting each material claim.
Start from corroborated addresses or transactions and trace each hop without assuming the educational flow is exact.
Compare decoded calls, logs, bytecode, and state changes with the reported cause.
Record provenance for every claim and identify gaps that still require confirmation.
Source status: cataloged. Classification: educational. Risk methodology: heuristic only. Primary-source verification remains required for every material claim.
