DeFi Gets Its First Credit-Style Rating as weETH Scores A+ From Credora

Credora by RedStone has assigned an A+ rating to weETH, the liquid restaking token issued by Ether.fi, marking the first time a token of its kind has received an independent, simulation-based risk assessment of this grade. The rating, published on 26 June, places weETH’s annualised probability of default at 0.098%, a figure its issuer likens to investment-grade corporate debt in traditional finance.

The development is significant for a decentralised finance sector that has long relied on total value locked as its primary, and largely backward-looking, measure of health. Credora’s methodology instead applies 100,000 Monte Carlo simulations to stress-test each asset, producing a forward-looking estimate of failure risk rather than a snapshot of current deposits.

A methodology built for institutional scrutiny

Credora’s scoring system starts from a baseline probability of default of 0.16% and adjusts the figure up or down according to factors including reserves transparency, governance quality and market adoption. Ratings run on a standardised scale from A+ to D and are updated daily, a cadence its operators say reflects the continuous nature of onchain markets rather than the quarterly cycles used by conventional credit agencies.

weETH’s A+ grade sits alongside that of stETH, Lido’s liquid staking token, which carries a probability of default of 0.10%. At the time of the rating, weETH held $3.08 billion in total value locked, equivalent to 78.1% of the entire liquid restaking market, according to Crypto Briefing.

Security response factored into the score

Ether.fi’s handling of a security incident affecting the broader restaking ecosystem in April 2026 appears to have influenced the assessment. After KelpDAO’s rsETH bridge was exploited, Ether.fi moved pre-emptively to tighten its own weETH bridging protocol, adopting a 4-of-4 Decentralised Verifier Network quorum requiring unanimous sign-off from all verifiers on cross-chain transactions. No user funds were lost in the incident, according to the source.

That proactive response, combined with weETH’s dominant market share and disclosed reserves, was cited as contributing to an adjusted default probability below Credora’s 0.16% baseline.

RedStone’s vertical bet on risk infrastructure

The rating is the latest output of RedStone’s acquisition of Credora, completed in September 2025, which combined RedStone’s existing oracle and price-feed infrastructure with Credora’s risk-modelling capability under the Credora by RedStone brand. Protocols such as Morpho and Spark, which already draw on RedStone’s data feeds, can now access integrated risk metrics without sourcing a separate third-party provider.

For institutional allocators, the emergence of a standardised, quantitative risk benchmark addresses a long-standing gap between DeFi yield products and the credit-rating conventions of traditional finance. With weETH and stETH now both rated A+, other liquid restaking tokens face pressure to pursue comparable independent assessments if they intend to compete for regulated or institutional capital flowing into the sector.
