Ellipsis Labs

Ellipsis Labs builds decentralized finance applications and infrastructure on Solana. Its flagship product is Phoenix, a fully on-chain, atomically-settled limit order book exchange for spot assets, now expanded with Phoenix Perps for on-chain perpetual futures. The team also develops Atlas (a high-performance DeFi Layer 2), Gavel (token distribution and liquidity bootstrapping), and Plasma (a sandwich-resistant AMM reference implementation). Ellipsis exposes its protocol to developers through open-source SDKs (TypeScript, Rust, Python), command-line tools, and on-chain Solana programs rather than a hosted REST API. Backed by Electric Capital and Paradigm.

Ellipsis Labs is profiled on the APIs.io network. Tagged areas include Company, Defi, Solana, Blockchain, and DEX.

Ellipsis Labs’ developer surface includes documentation, CLI, and 12 more developer resources.
