Cega

Cega is a decentralized exotic derivatives protocol building on-chain structured products for investors: exotic options such as Fixed Coupon Notes (pure options and bond + options) and Dual Currency Swaps that generate yield with built-in downside protection. Cega is live on Ethereum Mainnet and Arbitrum One (EVM) and on Solana, and exposes its protocol to developers through first-party TypeScript SDKs on npm (@cega-fi) plus a GraphQL subgraph rather than a hosted REST API. Backed by Pantera Capital and surfaced into the API Evangelist network from its VC portfolio.

Cega is profiled on the APIs.io network. Tagged areas include Company, Crypto, DeFi, Derivatives, and Options.

Cega’s developer surface includes documentation and 8 more developer resources.
