Stader Labs

Stader Labs is a non-custodial, smart-contract-driven liquid staking platform for Proof-of-Stake networks. It lets retail users, exchanges, and custodians stake crypto and receive tokenized liquid staking tokens (ETHx, MaticX, BNBx, NEARx and others) that stay usable across 40+ DeFi protocols while earning auto-compounding rewards, with no lock-up and no minimum stake. Stader operates as multi-chain middleware infrastructure across Ethereum, Polygon, BNB Chain, Hedera, Fantom, and NEAR, and its contracts have been audited by Sigma Prime, Halborn, Peckshield, Code4rena, and OtterSec. The project is on-chain and open source rather than a REST/OpenAPI provider; developer surface area is Solidity/Go/Rust smart contracts, node software, and CLI tooling on GitHub.

Stader Labs is profiled on the APIs.io network. Tagged areas include Company, Crypto, DeFi, Liquid Staking, and Blockchain.

Stader Labs’ developer surface includes documentation, engineering blog, support, and 5 more developer resources.
