Regulatory infrastructure for connected data, calculations, decisions and outputs.

Regulatory infrastructure

Get the regulatory job done.

Connect financial data, execute regulatory calculations, and produce reports with evidence attached.

Discuss your workflow · See how it works

Illustration of fragmented data entering Regit's governed record and continuing through product work toward regulated assets.

Source revisions, rules and decisions stay linked to the work they support, so teams can understand a result and act on it without reconstructing its history.

Ways to work

  • Workspace: prepare and review work with its evidence in view.
  • API and CLI: connect systems and run defined operations.
  • MCP and A2A: bring scoped operations into agent workflows.

Open-source Rust libraries

We publish reusable financial models, calculation conventions and identifiers. We also publish regit-web3, a set of Web3 primitives from our exploration of how the same operating model could support another domain. The libraries are separate from Regit's governed platform and do not, by themselves, produce a regulatory determination.

Library What it provides Release Crate downloads
regit-svi Volatility smiles, surfaces and calibration regit-svi version regit-svi downloads
regit-blackscholes Options pricing, Greeks and implied volatility regit-blackscholes version regit-blackscholes downloads
regit-covariance Covariance denoising, shrinkage and detoning regit-covariance version regit-covariance downloads
regit-curves Yield-curve construction and interpolation regit-curves version regit-curves downloads
regit-daycount Day-count fractions and business-day calendars regit-daycount version regit-daycount downloads
regit-identifiers Securities, entity and market identifier validation regit-identifiers version regit-identifiers downloads
regit-web3 Chain and provider reads, swap quotes and transaction preparation regit-web3 version regit-web3 downloads

These live badges show crates.io releases and total crate downloads, not unique users. See each repository for its current implementation details.

For the thinking behind the Web3 work, read Testing Regit across new domains with the same operating model. Explore all published libraries on our open-source page.

Regit is based in Luxembourg. Discuss a workflow or contact us by email.
