Saffron Finance

Saffron Finance is a decentralized peer-to-peer interest-rate risk adjustment protocol built on Ethereum. Underlying DeFi yield is transformed by a smart-contract vault system according to each user's indicated risk preference, splitting deposits into senior (fixed-income, risk-averse) and junior (variable, risk-seeking) tranches across Uniswap V3 fixed-income vaults. The protocol is governed by the Saffron DAO and its SFI token, and was surfaced in the API Evangelist network as a portfolio company of Multicoin Capital in the crypto-web3 sector. Saffron is an on-chain protocol rather than a hosted web-API provider: its developer surface is Solidity smart contracts, published documentation, audits, and whitepapers rather than a REST/HTTP API.

Saffron Finance is profiled on the APIs.io network. Tagged areas include Company, Web3, DeFi, Yield, and Fixed Income.

Saffron Finance’s developer surface includes documentation, getting-started guide, engineering blog, support, and 7 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Horizontal (data, software, accessibility, platform) regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/saffron-finance/apis.yml: open an issue on github.com/api-evangelist/saffron-finance to ask a question or point us at an artifact you publish.
