Follow the money on-chain.
Argos is Functori's on-chain intelligence product: an investigation platform, blockchain data, a query engine and an AI interface, for investigators, compliance teams and integrators, built on Ethereum.
Five ways to use Argos.
All on quote. Tell us your use case, we tell you what fits.
Investigation platform
Address profiles built from several sources, fund-flow graphs from 1 to 10 hops, ERC-20 approvals, and transaction-level labelling of arbitrage, sandwich and liquidation activity.
Blockchain data
on requestThe decoded history of a chain (transfers, internal calls) and enriched datasets (DeFi labels), delivered as exports or through the API.
Argos Engine
newA query engine over the full transfer history of a chain: balances and flows of any address at any block, answered in milliseconds, on your own servers.
AI interface
pilotA Model Context Protocol (MCP) server lets an AI assistant query Argos with verified data. Public demo on a Tornado.Cash case.
Analyses on request
serviceOur analysts run the investigation for you and deliver a written analysis of the flows.
Built to sit inside your platform.
For platforms that want on-chain intelligence without building it: integrate Argos under licence, on your infrastructure.
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
Built on Ethereum; other EVM chains can be added for a project.
Built in France
Developed by a French company, in research funded by Bpifrance and the European Union.
Built with research labs, used in a European law enforcement project.
Research-grade origins
Developed in a Bpifrance i-Démo consortium coordinated by Functori, with Tarides, LIP6 (Sorbonne Université) and LMF (Université Paris-Saclay).
In a European law enforcement project
Argos is the crypto-analysis tool of CryptoACTION, a Horizon Europe project with 17 partners including 8 law enforcement agencies.
Proved where it matters
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.
Before you ask.
Which chains does Argos cover?
Ethereum mainnet. The core is EVM-generic, so other EVM chains can be added for a project.
Can Argos run inside our network?
Yes. Argos is designed to be deployed on the client's own infrastructure.
Can we buy the data only?
Yes. Decoded history and enriched datasets are available as exports or through the API, scoped to your needs.
Can we integrate Argos into our own product?
Yes, under licence, through the API or the engine on your servers.
How is Argos priced?
On quote, per project or per licence.
