Euler

Lending · EUL · $0.3B TVL. Euler is the screen's redemption case. The March 2023 flash-loan exploit drained $197M — one of the largest in DeFi history — and the attacker returned essentially all of it after negotiation. The protocol then spent two years rebuilding into Euler v2, a modular lending kit, and is now one of only three protocols in the universe with positive twelve-month TVL growth.

Axis I · Credit Grade

Solvency — BBB

Solvency screens at BBB. Fee coverage (~1.5x) from a small base, the shallowest drawdown in the small-cap cohort (30%), and moderate unlocks. The 6/10 risk score is where 2023 remains recorded — but the framework distinguishes sharply between an exploit that was made whole and one that was not, and Euler's full repayment is why this appears as a risk-score deduction rather than a notching cap.

Axis II · Legitimacy Score

Legitimacy — A

Legitimacy screens at A, and the exploit response is a positive contributor rather than merely a survived event. Disclosure was immediate, negotiation successful, users made whole, and the rebuild included formal verification and a substantially expanded audit program. This is the Legitimacy axis measuring exactly what it was designed to measure: how a team behaves when everything goes wrong.

Verdict

Where Euler Lands

Composite BB, trajectory positive from a very small base. The screen's read: proven crisis behavior plus a credible second act. Among the most interesting full-rating candidates precisely because its worst event is already in the record.

Composite — Conservative (Recommended Headline)
BB
48 / 100 · lowest of the three dimensions

"A chain is as strong as its weakest link." The conservative composite takes the weakest dimension and inherits any notching cap, so a single structural weakness cannot be diluted by strength elsewhere.

Analyst Note
2023 exploit ($197M) fully repaid — exemplary response; v2 growing from small base.
Screen vs full rating. This is Methodology v1.0 applied in screening form: the same bands, weights, caps and grade scale as the full Aave workbook, reduced to the highest-signal metrics per dimension so the whole universe stays comparable in one table. Screen grades are provisional. A full rating — per-metric sourcing plus four stress scenarios — is produced when a protocol is selected for publication. Every input is an analyst estimate as of July 27, 2026, drawn from public data (DefiLlama, protocol docs, governance forums, rekt.news) and judgment, and should be verified before being relied upon.
