Blockchain protocols and EVM
Consensus, mempool, rollups, data availability and EVM execution nodes: we design, implement and review the core of chains, and build EVM tooling such as Apollo, an opcode-level transaction debugger.



We take on the parts of a system that are hard to get right and expensive to get wrong. Each field comes with what we actually shipped.

We design and operate sub-second latency DeFi systems on EVM mainnets. The same understanding of DeFi microstructure powers the arbitrage, sandwich and liquidation labelling in Argos.
Security reviews of smart contracts on EVM chains and Tezos, fuzzing and load testing of protocol code, typed languages and domain-specific languages, and machine-checked proofs for the few components where a bug is unacceptable.




Decoding and indexing the full history of a chain, turning it into investigation graphs, and connecting AI assistants to verified data instead of letting them guess, through an MCP interface to Argos and an industrial PhD on graph exploration.
