Noir Solidity ZK EIP

Full list: projects.

Running

xochi.fi : private exchange & friendly dark pool on Ethereum. ZK compliance via ERC-8262, the Zero-Knowledge Compliance Oracle standard we co-authored. axol.io runs the infra. Raising. The open infrastructure side is funded through Giveth.

Riddler

Intent solver, ~2s fills across five chains. P95 under 6s. LI.FI integrated it as a solver client. Also on Across, Everclear, soon Wormhole and COWswap.

Ethereum Optimism Base Arbitrum Polygon
axol.io infra
Production

Aztec sequencer, Ethereum validators, MEV searcher via Sphinx.

Aztec Ethereum Sphinx
Raxol
In progress

Terminal framework that grew payment rails. Agents can hold wallets and settle trades via x402/MPP.

Elixir OTP x402

Learning

Current reading list
  • MEV/HFT: searcher strategies, arb, liquidations, backrunning, latency
  • Quant: solver rebalancing, cross-chain inventory, execution optimization
  • Prediction markets: applying the quant work to Polymarket
  • ZK compliance: ZKSAR proofs, sanctions screening, provider weight tuning
  • OTP internals: gen_server, supervisor restarts, distributed Erlang

Location

Remote (Europe/Madrid). Remote.

Open to consulting. Ethereum protocol, ZK circuits, validator infra. Background.
