Ethena Labs

Ethena Labs is the crypto-native protocol behind USDe, a synthetic dollar backed by spot crypto assets, onchain custody, and delta-neutral hedging positions on centralized liquidity venues, alongside the staked savings instrument sUSDe (the "Internet Bond"), the governance token ENA, and USDtb. Ethena exposes a public Minting API for whitelisted institutional participants to mint and redeem USDe: a request-for-quote (RFQ) flow returns firm 15-minute quotes that are signed with EIP-712 (or EIP-1271 for smart-contract wallets) and submitted onchain. This profile was surfaced as a portfolio company of Ribbit Capital and enriched with the real developer surface documented at docs.ethena.fi.

Ethena Labs publishes 1 API on the APIs.io network. Tagged areas include Company, Crypto, Stablecoins, DeFi, and Synthetic Dollar.

Ethena Labs’ developer surface includes documentation, API reference, getting-started guide, support, authentication, changelog, and 19 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/ethena-labs: open an issue to ask a question, or submit a pull request to add artifacts.
