Sumer

Sumer (Sumer.Money) is a blockchain liquidity infrastructure protocol positioning itself as the most capital-efficient way to put crypto assets to work across chains. Users deposit native assets such as liquid staked ETH, and Sumer's correlation-aware risk engine matches assets and liabilities to mint synthetic suTokens (suETH, suUSD) that act as "money multipliers" — travelling across connected blockchains as collateral while the underlying deposit keeps accruing staking rewards and lending interest. The protocol runs an omnichain lending/borrowing market, a points and veSumer staking program, and its Supernova EVM chain, drawing price data from Chainlink, Pyth, RedStone, and Supra oracles. Backed by Pantera Capital and other crypto investors, with contracts audited by Certik, Ancilia, Tikkala, and CD Security.

Sumer is profiled on the APIs.io network. Tagged areas include Company, Crypto, DeFi, Blockchain, and Liquidity.

Sumer’s developer surface includes documentation, getting-started guide, engineering blog, support, signup flow, and 6 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/sumer: open an issue to ask a question, or submit a pull request to add artifacts.
