Tokenized funds
NAV-based investment vehicles tokenized for institutional treasury and DeFi composability. KYC + accreditation gated by the issuer (Securitize, Hashnote, Ondo, Maple). Rivier never sees client KYC documents — onboarding deeplinks to the issuer.

The bridge router refuses to quote a permissioned tokenized fund — the contract gate would revert the swap and waste user gas. Instead, the curator and asset-detail surfaces deep-link to the issuer's onboarding portal. Once a counterparty is onboarded, Rivier surfaces holdings via wallet-watcher integrations (no custody handoff).
