Over the last eight years, we have built 47 products and shipped features, tools, and systems for Google, Discord, State Street, SushiSwap, and Morpho.
For teams building on or integrating stablecoin infrastructure and payments, XORS brings rare cross-stack depth, both onchain and off-chain.
Core Capabilities:
Our Standard:
We pride ourselves on being more than hands for hire. We embed as thinking partners who offer senior expertise at every stage and build with security, iterability, reliability, and - most importantly - total alignment with your team.
Our senior talent provides elite efficiency, operating with absolute precision and speed to push the highest quality code with the least overhead.
XORS contributed core engineering to one of the highest-fidelity DEX aggregators on Base, building a multi-hop routing engine with beam-search pruning and a convex split-optimizer across 15+ venues including Uniswap V2/V3/V4, Aerodrome, and PancakeSwap. The result: sub-30bp price parity against leading aggregators Odos, Relay, and KyberSwap on benchmark trades, with full onchain execution.
We engineered the full fiat-to-crypto flow on DreamOS (a crypto super-app) combining complex fiat on/off-ramping flows with options trading into a seamless consumer experience, delivering $5M in notional volume on day one with the conversion funnel operating at scale from launch.
We built a HIPAA-compliant AI patient document pipeline for Hike Medical, engineered to pass the technical scrutiny of national enterprise buyers. By building confidence scoring, human-in-the-loop routing, and audit trails, we achieved 95% pipeline extraction accuracy and ensured the AI surfaces uncertainty rather than hallucinating data - directly enabling the client to secure a major national clinic chain.
