Following the recent security incident involving @SolidoMoney trading across the affected Dexlyn V2 pools has been temporarily paused as a precautionary measure. We’re coordinating closely with the Solido team and supporting them wherever possible. We’ll share further updates and trading to be resumed shortly.

We’ve designed and built our first AI chip: Jalapeño. Designed from the ground up by OpenAI and brought to production with @Broadcom, Jalapeño is purpose-built for the LLM workloads powering ChatGPT, Codex, the API, and future agentic products. Chips are foundational to the AI economy. Building our own expands our full-stack platform from products to models to infrastructure, and will help us scale intelligence, serve more people, and expand access to AI.

Case studies

01

Dexlyn - AMM -> CLMM

Built the path from testnet AMM to mainnet liquidity venue: 42k peak daily active users, whale LP migration, CLMM rollout, chart trust, and pricing without mature oracle support.

02

Dexlyn Perps

Led the perps surface from pair-level risk modeling to execution rebuild: funding scripts, OI limits, collateral work, and order placement cut from 18s to under 3.

03

Dexlyn Aggregator & Bridge

Researched and shipped the movement layer around Dexlyn: multi-hop routing, multi-fork execution, Hyperlane bridge flows, and bridged USDC.

04

Suprans

Led Suprans as identity infrastructure for Supra: .supra names, subdomains, records, renewals, leasing, and wallet/dApp interoperability.
