Integration and deployment

Platforms can license Argos and run it on their own infrastructure rather than build their own.

API and MCP

A programmatic API, and an MCP interface for AI assistants.

On your infrastructure

For agencies and regulated teams that cannot send data to a third party.

EVM-generic

Ethereum first; other EVM chains can be added for a project.

French and European

Functori is a French company, and the research behind Argos is funded by Bpifrance and the European Union.

Where Argos comes from

A Bpifrance research project

Argos was developed in a research consortium funded by Bpifrance and coordinated by Functori, with two academic labs and Tarides. Partners and budget

CryptoACTION

Argos is the crypto-analysis tool of CryptoACTION, a Horizon Europe project that includes law enforcement agencies. About the project

One proved algorithm

One of Argos's detection algorithms is machine-checked in the Rocq proof assistant, relative to transfer decoding, and was evaluated on 220,000 consecutive Ethereum blocks.

Questions

Which chains does Argos cover?

Ethereum mainnet. The core is EVM-generic, so other EVM chains can be added for a project.
