DeFi just got its version of a credit rating agency, and it’s already handing out grades. Credora by RedStone assigned weETH, the liquid restaking token from Ether.fi, an A+ rating on June 26, making it the first liquid restaking token to receive an independent risk assessment of this caliber.

The rating comes with a 0.098% annualized Probability of Default. To put that in perspective, that’s roughly the kind of default risk you’d associate with investment-grade corporate bonds in traditional finance. Except this time, the underlying asset lives entirely onchain.

What the rating actually measures

Credora doesn’t just eyeball a protocol’s TVL and call it a day. The platform runs 100,000 Monte Carlo simulations to stress-test each asset’s risk profile. At a 0.098% default probability, the answer is: almost never.

The methodology starts with a foundational Probability of Default of 0.16%, then adjusts up or down based on several factors. Reserves transparency, governance quality, and market adoption all feed into the final score.

For context, stETH, Lido’s liquid staking token, also holds an A+ rating from Credora. Its Probability of Default sits at 0.10%, just a hair above weETH’s number.

At the time of the rating, weETH carried $3.08 billion in total value locked. That figure represents 78.1% of the entire liquid restaking market.

The RedStone-Credora backstory

This rating didn’t come out of nowhere. RedStone, the oracle protocol, completed its acquisition of Credora back in September 2025. The result was a rebranded entity called Credora by RedStone, purpose-built to deliver simulation-based risk ratings for DeFi assets on a standardized scale from A+ down to D.

The logic behind the acquisition was straightforward. RedStone already supplied price feeds and data to major DeFi protocols. Adding a risk assessment layer on top of that data infrastructure created a vertically integrated offering. Protocols like Morpho and Spark, which already relied on RedStone’s oracle services, could now access integrated risk metrics without bolting on a third-party solution.

The ratings are delivered daily, not quarterly. This isn’t Moody’s operating on a legacy publishing cycle. It’s a system designed for markets that never close and where conditions can shift in hours.

How weETH earned its grade

The A+ rating isn’t just a function of weETH’s market dominance. Ether.fi’s response to a security incident in April 2026 played a meaningful role in the assessment.

When KelpDAO’s rsETH bridge was exploited earlier that year, Ether.fi proactively upgraded the weETH bridging protocol. The team moved to a 4-of-4 DVN (Decentralized Verifier Network) quorum requirement, meaning every single verifier must sign off on cross-chain transactions. No user funds were lost during the incident.

The combination of dominant market share, proactive security upgrades, and transparent reserves gave weETH enough positive signals to push its adjusted default probability below the 0.16% baseline.

What this means for investors

The weETH rating matters for reasons that extend well beyond one token’s bragging rights. It represents a shift in how capital allocators, particularly institutional ones, can evaluate DeFi yield products.

A simulation-based default probability offers something TVL never could: a forward-looking measure of risk. It tells you not just how much money is currently parked in a protocol, but how likely that protocol is to experience a failure event under stress conditions.

Now that weETH has an A+ rating sitting alongside stETH, other liquid restaking protocols face a clear benchmark. Any LRT hoping to attract institutional capital will likely need to pursue a similar independent assessment.
