Stader

Stader Labs is a non-custodial, smart-contract-driven liquid-staking protocol that lets users stake crypto assets and earn rewards while retaining liquidity through liquid-staking tokens (ETHx, MaticX, BNBX, HBARX, NEARx) usable across 40+ DeFi protocols. Stader operates across multiple chains — Ethereum, Polygon, BNB Chain, Hedera and NEAR — with open-source smart contracts and node tooling. Its developer surface is on-chain contracts, a Go node client (stader-node) and permissioned CLI, and public GitHub source rather than a hosted REST/OpenAPI API. This profile was surfaced as an Accel portfolio company and enriched by the API Evangelist pipeline; probes confirm no public HTTP API, well-known discovery, or llms.txt surface at this time.

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

Stader’s developer surface includes documentation and 4 more developer resources.
