Overview

What NautPay is, how the products fit together, and what makes it different.

NautPay is an AI-powered stablecoin payment agent on Solana with built-in compliance intelligence.

Users connect a wallet (Phantom or Solflare), complete a cryptographic wallet ownership proof, and then issue payments in plain English. The agent parses intent via Claude Haiku, runs compliance pre-flight checks against NautLense, executes on-chain, and captures the full audit trail automatically.

Products

NautPay (Open Source)

The open-source payment frontend. Natural language interface, wallet integration, onboarding flow, and compliance visibility.

Stack: Next.js 14, TypeScript, Tailwind CSS, Solana Wallet Adapter

Engrm.ai (Proprietary)

NautLense's compliance engine is adapted from Engrm.ai, a production organisational intelligence platform processing 170K+ records. The core infrastructure — vector search, knowledge graphs, pattern detection — is battle-tested. The crypto compliance vertical is the application layer built on top.

What Makes This Different

Compliance is built in, not bolted on — Every stablecoin transfer goes through risk assessment before execution
Chain-agnostic engine — NautLense works for any blockchain. Adding Ethereum is ~100 lines of adapter code
Production-proven infrastructure — Core engine adapted from Engrm.ai (170K+ records in production)
Hash chain audit trail — SHA256 chain: tamper one record and it breaks. Verifiable integrity
Real cryptographic wallet verification — ed25519 / secp256k1 signature proofs, not checkbox attestations
Self-hosted compliance — No middleman. No per-transfer fees. Data stays under operator control
