DeFi risk rating platforms compared: Credora vs S&P vs Moody’s vs Particula

DeFi surfaces the yields, but never the risks. In Q2 2026 alone, DeFi hacks cost the space some $780M worth of losses, but you won’t see that number next to a protocol’s target APY. Nor would you see the probability of joining the statistic there. A DeFi risk rating is the instrument that closes that gap, and there are now four providers issuing one.

The tides are turning, though, as crypto is growing more institutional. Institutions and enterprises operate at scale, and their decision-making always factors in the risk. A treasury manager exploring stablecoin vaults must present the risk committee with a defensible, clear-eyed account of the risk profile at hand. The same applies to any decision involving institutional-grade capital deployments.

A gap rarely stays open for long. Accordingly, a growing number of platforms and agencies are now offering DeFi risk ratings in a bid to deliver capital allocators the information they need to engage with DeFi. Credora is one of them, and here is how it compares to some of the others.

How the four DeFi risk rating providers compare

Category	Credora	Moody’s	S&P Global Ratings	Particula
Risk structure	Credora runs Probability of Default (PD) for assets, rates markets based on Monte Carlo simulation-driven Probability of Significant Loss (PSL). Each risk assessment also includes category-specific additional modifiers.	Moody’s applies advance rates by reserve-asset type and maturity plus operational/liquidity/tech risk.	S&P combines an asset assessment with five additional considerations (governance, legal and regulatory framework, redeemability and liquidity, technology and third-party dependencies, track record) into one non-probabilistic 1–5 grade.	Particula runs 129 discrete risk attributes through three weighted pillars: Underlying Asset (50%), Structure (30%), Counterparty (20%).
Scope	Credora covers tokens (including wrapped/LST/LRT derivatives, stablecoins, and tokenized assets), lending markets, and vaults.	Moody’s scope spans stablecoins, tokenized funds/MMFs, and digital bond issuances.	S&P’s SSAs cover 11 stablecoins.	Particula only covers asset-backed tokens.
Smart contract coverage depth	Credora scores smart contract security as one of the main anchors. Addresses audit quality (scope, mitigation reviews, recency, and formal verification), audit quantity, bug bounty and contract maturity.	No dedicated smart contract risk pillar. Technology risk is covered at framework level.	Tech risk bundled with 3rd party risk.	Particula’s Structure pillar (30% weight) covers smart contract security and redemption mechanisms.
Distribution	Live distribution as a UI primitive on two major venues with a combined TVL of $15B+ (Morpho and Spark) as well as via the public-facing Credora App.	Distributes ratings directly onchain via its proprietary Token Integration Engine, currently live on Canton and Solana.	SSA ratings distributed onchain via Chainlink’s DataLink.	The ratings are available via Enzyme, Ownera SuperApps, Obligate, and Multiliquid, as well as Particula’s own website.
Output legibility	An A+ to D rating scale mapped to a proprietary “PD Curve” built from 1990–2023 historical default data pulled from S&P, Moody’s, and Fitch. The only one of the 4 with a public dashboard.	Moody’s standard Aaa–C letter-based ratings applied to onchain assets.	A 1-5 numeric grade, not probabilistic in nature.	AAA–D letter ratings with subgrades.
Size	$40M valuation before RedStone acquisition. Team size <20 people.	Moody’s Corporation is a publicly-traded company with a $88B+ market cap. It employs approximately 16,000+ people globally.	S&P Global Inc. is a publicly-traded company with a market cap of over $128B and employs about 44,500 people globally.	No publicly-disclosed valuation after the $5.5M funding round in April 2025. 11-50 employees as per LinkedIn.
Structural Recognition	Credora’s ratings are only reflected in capital allocators’ decisions on a voluntary basis.	Moody’s is one of the 10 companies in the US to hold the status of a Nationally Recognized Statistical Rating Organization, first shortly after the status was established in 1975 and then reconfirmed in late 2000s. Its ratings and data inform US federal rules, and being NRSRO-rated often determines an asset’s eligibility for pension funds and other institutional actors. Moody’s is estimated to hold roughly 40% of the global credit ratings market.	S&P is one of the 10 companies in the US to hold the status of a Nationally Recognized Statistical Rating Organization, first shortly after the status was established in 1975 and then reconfirmed in late 2000s. Its ratings and data inform US federal rules, and being NRSRO-rated often determines an asset’s eligibility for pension funds and other institutional actors. Like Moody’s, S&P is estimated to hold roughly 40% of the global credit ratings market.	Particula’s ratings are only reflected in capital allocators’ decisions on a voluntary basis.
TradFi Dataset Depth	Credora’s models are calibrated on the same historical data as S&P and Moody’s, but the firm itself has no comparable live track record.	Moody’s has rated corporate, sovereign, and structured debt through multiple full credit cycles since 1909.	S&P has rated corporate, sovereign, and structured debt through multiple full credit cycles since 1860.	No independent TradFi track record, methodology not shown to be calibrated on historical agency default data. But Particula has recruited TradFi credibility directly: a 20+-year Moody’s veteran (former Global Head of Relationship Management) as senior advisor, plus separate proof-of-concept collaborations with both Moody’s and S&P on digital asset risk analytics.

Comparison based on publicly available methodology documents as of September 2026.

Credora

Credora is a DeFi risk intelligence engine assigning A+ to D grades to onchain assets, markets, and rehypothecated markets. For each category, the ratings are based on a well-documented methodology accounting for their specifics. Assets are rated based on their PD, or the probability of a default; markets are rated by PSL, or probability of significant loss, which is calculated based on 100,000 Monte Carlo simulations. Both also include additional risk factors, specific to what’s being rated.

The result is a probabilistic rating that is mapped to the letter-based grades. The mapping was done based on 30+ years’ worth of data from Moody’s, S&P, and Fitch, translating the probabilities to TradFi’s familiar risk rating convention.

Credora’s methodology scope is the widest in its reach across the services compared, extending to anything from crypto-native derivatives, such as wrapped BTC, to markets on Morpho and Spark. The methodology is first and foremost data-driven, with the human inputs amounting to monitoring and verification; the analyst judgement and bias are out of the picture.

Credora’s rating distribution stretches from the UI of major DeFi protocols (Morpho, Spark) to its own app featuring ratings for 160+ vaults, 250+ markets, and 60+ assets, most of them open to the public. More and more ratings will be joining the public pool over time.

The relationship with RedStone positions Credora into the institutional space through the former’s network of partnerships and contacts. As the price data layer powering BlackRock’s BUIDL and Apollo’s ACRED, RedStone grants Credora vast institutional reach without compromising its independent voice.

Credora’s strengths include the nuanced and open methodology, which enables it to rate both assets and markets of varying complexities, a grade that easily translates into TradFi recognition while still carrying probabilistic value, and an efficient distribution system putting it right before capital allocators at major platforms.

In terms of weaknesses, Credora lacks the sheer size and funding that traditional rating agencies bring to the table. A track record of more than a hundred years brings a level of institutional veneer that Credora, founded in 2019, never had the time to develop. For S&P and Moody’s, this veneer translates into institutional recognition that makes these agencies structural industry stakeholders whose ratings inform the decisions of hundreds of entities around the globe, from government bodies to funds and corporate treasurers. Credora does not possess the same structural status.

Moody’s

Founded in 1909, Moody’s is a TradFi credit rating agency covering a broad range of asset classes, including corporate and government bonds, collateralized loan obligations, money market funds, and more. In March 2026, it expanded its scope to the blockchain world, launching the Token Integration Engine to bring its ratings onchain.

Moody’s methodology is narrower in scope, compared to Credora: it only focuses on fiat- and asset-backed stablecoins, which removes a wide array of DeFi-native wrappers, such as liquid staking tokens, out of the equation. The methodology also doesn’t dive as deep into smart contract risks. The strength, for its part, is in the institutional brand recognition, including for its Aaa—C grading scale, well-known to TradFi risk managers. Investment-grade bond indices like the Bloomberg US Aggregate require a bond to carry investment-grade ratings to even be included, meaning trillions of dollars of passive, index-tracking capital simply cannot hold an asset that agencies like Moody’s or S&P haven’t rated favorably.

S&P Global

Dating back to 1860, S&P Global is a TradFi credit rating agency evaluating the creditworthiness and financial stability of entities that issue debt, and the entity behind the S&P 500 stock index. In 2021, S&P Dow Jones Indices introduced its first crypto benchmarks, starting with the S&P Cryptocurrency Index Series tracking Bitcoin and Ethereum. Then, in 2023, S&P Global Ratings launched its evaluative Stablecoin Stability Assessments (SSAs) to score a coin’s ability to maintain its peg.

S&P’s SSAs are only covering 11 stablecoins, including USDC, USDT, USDP, and others. Its numerical 5-step grading scale does not deliver probabilistic information, and the methodology is not as granular as Credora’s on the thresholds in multisig setups, timelock hours, and various other smart contract-related metrics. The strengths, on the other hand, lie in institutional recognition and its handling of the assets’ history, with Track Record as a standalone modifier. The same index-eligibility threshold applies: investment-grade bond indices such as the Bloomberg US Aggregate admit only investment-grade rated bonds, so trillions of dollars of passive capital cannot hold an asset S&P has not rated favorably.

Particula

Founded in December 2022, Particula rates asset-backed tokens (tokenized financial instruments, commodities, real estate, and pegged payment tokens), but explicitly excludes BTC, ETH, and other tokens without a defined economic structure behind them. In March 2026, Particula extended the framework onchain through PDARP, a “risk passport” that publishes machine-readable risk signals directly to smart contracts across 30+ EVM and non-EVM networks.

PDARF breaks a rating into 129 individual risk attributes rolled into three weighted pillars, producing an AAA-to-D grade with +/- sub-notches. Like S&P’s, it’s an ordinal ranking rather than a probability. A parallel Data Confidence Score tracks completeness across 199 data points, with automated Trend Detectors and Red Flags for anomalies. Onchain data updates in real time and issuer/offchain data triggers event-based refreshes, but every score still passes a manual check at least once a month.

Particula’s strength is sheer granularity: its 129 discrete attributes are a more granular disclosure surface than what Credora currently publishes per asset, and PDARP’s onchain delivery is a genuine technical parallel to Credora’s approach. The tradeoffs are a lack of DeFi-native asset coverage, ordinal rather than probabilistic ratings, and bundling smart contract risk under the Structural pillar.

How to choose between them

The first filter is coverage, not quality. A methodology that cannot reach the position does not enter the comparison at all. If the exposure is a lending market or a vault, Credora is the only one of the four that rates it. If it is one of eleven specific stablecoins, S&P has an assessment. If it is a tokenized fund or a digital bond, Moody’s does. If it is an asset-backed token with a defined economic structure, Particula does.

The second filter is what the output has to do. A probability can be multiplied by an exposure and carried into a risk model. An ordinal rank cannot, and has to be translated first. Credora is the only one of the four that hands over a probability.

The third filter is whether the rating has to satisfy someone other than the reader. If a mandate, an index, or a regulator requires a rating from a Nationally Recognized Statistical Rating Organization, only Moody’s and S&P clear that bar, and no amount of methodological depth from the other two substitutes for it. That constraint is structural rather than analytical, and it is the reason these four are not straightforwardly substitutes for one another.

Key takeaway

Four providers issue DeFi risk ratings, and they answer different questions. Credora is the only one producing a probabilistic output across tokens, lending markets, and vaults, and the only one that treats smart contract security as a standalone anchor rather than a component of a broader pillar. Moody’s and S&P bring regulatory standing and a track record measured in centuries, but cover a narrow slice of onchain assets and issue ordinal grades. Particula offers the most granular disclosure surface of the four within a deliberately restricted scope. Coverage determines which providers can be considered at all; output form determines what can be done with the result; and structural recognition determines whether the rating satisfies a mandate.

Frequently asked questions

Which DeFi risk rating providers cover lending markets and vaults?

Of the four providers compared here, only Credora rates lending markets and vaults alongside tokens. Moody’s covers stablecoins, tokenized funds and digital bond issuances. S&P covers eleven stablecoins under its Stablecoin Stability Assessments. Particula covers asset-backed tokens and explicitly excludes assets without a defined economic structure.

What is the difference between a probabilistic and an ordinal DeFi risk rating?

A probabilistic rating states a likelihood, such as a Probability of Significant Loss (PSL) expressed as an annualized percentage, which can be multiplied against an exposure and carried directly into a risk model. An ordinal rating places an asset in rank order relative to others without stating a likelihood. Credora produces a probabilistic output mapped onto a letter scale. Moody’s, S&P and Particula produce ordinal ranks.

Do DeFi risk ratings affect institutional mandate eligibility?

Only ratings from a Nationally Recognized Statistical Rating Organization carry eligibility consequences under US rules, and of the four providers compared here only Moody’s and S&P hold that status. Ratings from Credora and Particula inform allocation decisions on a voluntary basis and do not make an asset eligible for a mandate that requires an NRSRO rating.
