Protocols

Request coverage

Every protocol here carries a dated score and the share of it backed by independently verified evidence. Where that share is still thin the assessment says so, is marked Low-signal rather than given a risk band, and holds every unevidenced category at the neutral midpoint instead of assuming it safe. Every score and its reasoning are free to read; the underlying dependency, incident and audit records are part of a plan. Each reading here is fixed at the date beside it. Re-scoring never stops, but a changed reading reaches plan holders on the day it changes rather than this page, which is what a plan is for. How a score is built, how to read one, and how the rubric was tested against real exploits are all in the methodology.

Coverage grows three ways: protocols Foreshock selects at its own discretion, protocols requested through the Request coverage button, and sponsored assessments delivered on an agreed timeline. No path has a guaranteed date except sponsorship.

Scores run from 0, the safest reading, to 100, the riskiest, where 50 is the neutral midpoint every unverified category is held at. Red marks a protocol scoring 50 or above, the band called Elevated: worse than neutral on the evidence gathered. Amber marks one below it, called Moderate. The boundary is fixed. It does not move as coverage grows, and it is not fitted to any backtest result.

:

  • Evidence: this reading is based on 100% of the scored weight, verified against named sources. Categories without verified data are held at the neutral midpoint at their full weight, never counted as safe.
  • Validation: the rubric is backtested against past exploits of protocols in the same TVL, age and category bucket. Protocols of this scale and kind have no such history - a limit of the record itself, not unfinished work.

Why this rating
Audit profile10.0
5 audits/contests on record, most recent (ChainSecurity, 2025-10-24) has unread findings, scored as unknown, not assumed clean.
Dependency risk7.5
Uses 2 oracles (USDD learns what its collateral is worth from Chainlink and WINkLink price feeds, which are combined by a Median contract and passed through a delayed Oracle Security Module before the lending system acts on them.).
Code characteristics7.5
Admin key: none.

Governance concentration/quorum data unknown.
TVL profile3.5
TVL change (-3%) is within a stable range.

No known own or inherited incidents as of 6 September 2026.
Team factors1.7
Doxxed team, track record: unknown.
Protocol age1.5
542 days live, past the ~1yr floor; treated the same as any older protocol, not scored progressively safer with more age.

Common questions about USDD

Foreshock's independent reading of USDD is Moderate risk, 42.3 out of 100, as of 6 September 2026. The largest single contributor to that reading is audit profile: 5 audits/contests on record, most recent (ChainSecurity, 2025-10-24) has unread findings, scored as unknown, not assumed clean. All nine scored categories are backed by verified evidence. This published reading is fixed at that date. Re-scoring never stops, and when a reading changes it reaches plan holders on the day it changes rather than this page. Foreshock publishes the reading and the reasoning behind it. It is not a verdict on whether to use this protocol, and it is not investment advice.

Is USDD safe?
Foreshock does not answer that as a yes or a no. Its independent reading of USDD is Moderate risk, 42.3 out of 100, as of 6 September 2026, led by audit profile: 5 audits/contests on record, most recent (ChainSecurity, 2025-10-24) has unread findings, scored as unknown, not assumed clean. The score and the reasoning are published in full so the reading can be checked rather than trusted.
Has USDD been audited?
5 audits/contests on record, most recent (ChainSecurity, 2025-10-24) has unread findings, scored as unknown, not assumed clean. An audit describes the code at the time it was reviewed. It is not a statement that the protocol is safe today.
Who controls USDD?
Admin key: none. Governance concentration/quorum data unknown.
Has USDD been exploited before?
No known own or inherited incidents as of 6 September 2026. Foreshock records an incident against a protocol whether it originated there or was inherited from something it depends on.
When was this USDD assessment last updated?
6 September 2026, and that date does not move on its own. A reading published here is fixed when it is published; re-scoring never stops, and a changed reading reaches plan holders on the day it changes rather than this page. Every category carries the date of the evidence behind it.

This assessment follows Foreshock's published methodology. Exact category weights, scoring rules, thresholds, and aggregation logic are proprietary and not shown here. How to interpret this assessment

This reading will change.

This reading is fixed at the date above it, and it stays there. We keep re-scoring USDD as the evidence moves, a new audit, a changed admin control, an incident, and this page is free to read and always will be. The updated reading is what a plan buys: you are told by email on the day it changes, instead of finding out the next time you happen to look.
