A working prototype of permissioned RWA infrastructure on Base mainnet.
The KANN alpha demo is now available at app.kann.tech. This is a B2B whitelabel technology prototype running on Base mainnet with minimal funds deployed for testing purposes.
The demo is available in Switzerland and EU jurisdictions only. Access is not available from:
Users must acknowledge their jurisdiction before accessing the application. This restriction applies to the demo interface - the underlying smart contracts on Base mainnet are permissionless infrastructure.
The alpha demonstrates core KANN infrastructure components:
Token contracts with integrated KYC verification via Sumsub. Issuers define eligibility criteria; the Allowlist contract enforces on-chain access control.
Qualified investors can subscribe to tokenization offers. The subscription flow handles eligibility verification, document acknowledgment, and settlement.
Uniswap V4 pools with custom hooks enforce eligibility and NAV guardrails at the swap level. Trading is restricted to allowlisted addresses and pauses when NAV data is stale.
Off-chain NAV calculations are attested and published on-chain. The oracle feeds into both primary subscriptions (pricing) and secondary hooks (freshness checks).
The Allowlist contract provides a unified eligibility registry. Token transfers, subscriptions, and secondary trades all check against the same on-chain state.
This is a working prototype intended to demonstrate technical feasibility. It is not production infrastructure, not audited for security, and not intended for real capital deployment.
No warranties are provided. This is not investment advice. The demo exists to show what permissioned RWA infrastructure looks like when built on public chain primitives.
