Sturdy

Sturdy is a decentralized liquid money market protocol for on-chain lending and borrowing. Sturdy V2 uses a two-tier architecture: a base layer of risk-isolated lending pairs, where each siloed market consists of a single lending asset and a single collateral asset, and an aggregation layer on top that lets lenders choose acceptable collateral types while avoiding liquidity fragmentation. The protocol is oracle-agnostic (using RedStone, API3, and eOracle feeds depending on the market), is governed by the $STRDY token and the Sturdy DAO, and has been audited by Zellic, ChainSecurity, Spearbit, Certik, Code4rena, and Quantstamp. Sturdy is an on-chain smart-contract protocol rather than a hosted REST API: its developer surface is the published smart contracts, oracle integrations, and the Sturdy Subnet, with no first-party web API, SDK, or OpenAPI. This profile was surfaced as a portfolio company of Pantera Capital.

Sturdy is profiled on the APIs.io network. Tagged areas include Company, Crypto, DeFi, Lending, and Money Market.

Sturdy’s developer surface includes documentation, engineering blog, support, and 4 more developer resources.

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.

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 github.com/api-evangelist/sturdy: open an issue to ask a question, or submit a pull request to add artifacts.
