@fabrknt/complr-core

AI-powered compliance engine for digital assets -- regulatory intelligence, transaction screening, and SAR/STR reporting across MAS, SFC, and FSA jurisdictions.

Not every DeFi protocol needs TradFi compliance -- but if yours does, you shouldn't have to rebuild from scratch. Fabrknt plugs into your existing protocol with composable SDKs and APIs. No permissioned forks, no separate deployments.

Install

npm install @fabrknt/complr-core

Quick Start

import { Complr } from "@fabrknt/complr-core";
import type { TransactionDetails, Jurisdiction } from "@fabrknt/complr-core";

const complr = new Complr({ anthropicApiKey: process.env.ANTHROPIC_API_KEY });

// Add regulatory documents to the knowledge base
complr.addDocument({ id: "mas-psa", jurisdiction: "MAS", title: "...", content: "..." });

// Query regulations in natural language
const answer = await complr.query("What is the Travel Rule threshold?", "MAS");

// Check transaction compliance across jurisdictions
const result = await complr.checkTransaction({
  transactionId: "tx_001",
  senderWallet: "0xabc...",
  recipientWallet: "0xdef...",
  amount: "10000",
  currency: "USDC",
});

Features

• Multi-jurisdiction compliance checks (MAS, SFC, FSA) in a single call
• Natural language regulatory queries with TF-IDF semantic search
• Confidence scoring and citation verification to mitigate LLM hallucination
• SAR/STR report generation in regulator-specific formats
• Obligation extraction from regulatory documents
• Regulatory delta analysis between document versions
• Multi-chain wallet address support (EVM, Solana, Bitcoin) with auto-detection
• Zero external dependencies for search, scoring, and screening logic
