Reflexer

Reflexer Labs builds RAI, a decentralized, non-pegged stable asset backed by ETH on Ethereum. Rather than tracking the US dollar, RAI uses an on-chain PID controller and algorithmic redemption rate to achieve relative price stability. The protocol is built on GEB, Reflexer's open-source framework of smart contracts for SAFEs (collateralized debt positions), liquidations, auctions, oracles, and governance minimization. Developers integrate via the geb.js (JavaScript/TypeScript) and pyflex (Python) SDKs and query protocol state through a hosted GraphQL subgraph (The Graph Protocol). Sector: crypto / DeFi stablecoins.

Reflexer publishes 1 API on the APIs.io network. Tagged areas include Company, Crypto, DeFi, Stablecoin, and Ethereum.

Reflexer’s developer surface includes documentation, API reference, getting-started guide, engineering blog, support, signup flow, and 11 more developer resources.
