Puffer Finance

Puffer Finance is an Ethereum infrastructure protocol building native liquid restaking (nLRP) integrated with EigenLayer, the UniFi based rollup, and Puffer Preconf preconfirmation services. Users stake ETH to mint the pufETH liquid restaking token and earn Ethereum staking plus EigenLayer and Puffer restaking yields. Puffer also ships institutional-grade staking infrastructure. It is an onchain, smart-contract protocol: developers integrate via its Solidity contracts, the first-party TypeScript puffer-sdk, and the Rust coral CLI rather than a hosted web API. Surfaced as a portfolio company of electric-capital and enriched in the API Evangelist network.

Puffer Finance is profiled on the APIs.io network. Tagged areas include Company, Defi, Ethereum, Liquid Restaking, and Staking.

Puffer Finance’s developer surface includes documentation, engineering blog, signup flow, support, CLI, and 9 more developer resources.
