The Compliance Bottleneck

Navigating sanctions in the fast-paced Web3 world is a significant challenge. Existing solutions often miss the mark for lean, agile teams.

🧩

Overly Complex Solutions

Enterprise platforms are bloated with features you don't need, leading to high costs and slow integration.

❓

Opaque Processes

Many vendors offer "black box" screening. How do you demonstrate proof of compliance checks transparently?

⏳

Developer Friction

Lengthy sales cycles, complex APIs, and restrictive "free" tiers slow down your development and innovation.

How It Works

  1. Monitor & Normalize Data:

    RuleRunner continuously ingests and normalizes data from key global sanctions lists (OFAC, EU, UK, etc.).

  2. Generate Merkle Root:

    This curated data is processed into a secure Merkle tree, with its root published regularly for verification.

  3. Make Your API Call:

    Your application calls our simple /isCompliant endpoint with transaction details.

  4. Receive Instant Check & Proof:

    RuleRunner instantly returns an allowed: true/false status, along with a Merkle proof, root, and data version.

  5. (Optional) Attest On-Chain:

    Utilize the provided proof in your smart contracts or store it for immutable auditability and transparency.
