Why real estate debt is absent from DeFi RWA collateral

Tokenized real-world assets on-chain cross $26B in early 2026. Of that, real estate debt is under 4%.

The gap is not demand. Institutional LPs want senior secured bond exposure with 7-10% coupon profiles. DeFi allocators need collateral that is not correlated with crypto cycles. The product-market fit is obvious.

The gap is infrastructure. Every current RWA protocol hit one of three walls: no issuing vehicle that a Tier-1 auditor will sign off on, no ISIN for settlement, no permissioning at the token level that satisfies the jurisdictional passporting requirements for the allocators most ready to deploy.

Tortuga inherits Estating's Luxembourg securitisation vehicle, Swiss ISIN pipeline, and Tier-1 audit engagement — and adds an ERC-3643 permissioning layer on top. The compliance perimeter is enforced on-chain at every transfer. The token is a permissioned representation of the underlying bond, not a synthetic wrapper.

Real estate debt is absent from DeFi RWA collateral because the infrastructure was absent. That is changing.
