# DeFi Integration

This document explains how Tortuga tokens interact with DeFi infrastructure — specifically Morpho Blue and the curator model for collateralized lending. The key architectural property that makes this possible is that compliance travels with the token. DeFi protocols do not need to implement their own KYC to accept Tortuga tokens as collateral.

Standard securitization products cannot be efficiently leveraged within TradFi infrastructure. ERC-3643 tokens enable collateralized borrowing against real estate bond exposure at DeFi rates. The compliance enforcement embedded in the token contract means that every transfer — including deposits, withdrawals, and liquidations — is subject to the same Identity Registry and Compliance Module checks that apply to a direct wallet-to-wallet transfer.

DeFi protocols accepting Tortuga tokens as collateral do not inherit KYC liability. The token enforces eligibility on every transfer regardless of which interface initiated it.

This is the property that enables institutional-grade DeFi participation without regulatory exposure for the protocol. A lending protocol does not need to implement its own KYC to accept Tortuga tokens as collateral. The compliance check is embedded in the asset, not in the venue.

Regulated DeFi composability. The compliance architecture makes it structurally possible for regulated assets to participate in permissionless DeFi infrastructure without compromising either the regulatory framework or the DeFi protocol's operational model.

Morpho Blue is a modular lending protocol that allows independent, curated lending markets to be configured for specific collateral types. The protocol itself does not gatekeep collateral — curators do.

Accessing Morpho Blue liquidity is not a matter of integrating with Morpho Labs. It requires separate negotiation with each independent curator who manages lending pools on the protocol.

Curators are independent risk managers who create and manage lending pools on Morpho Blue. Each curator independently defines:

• Accepted collateral types and contract addresses
• LTV ratios
• Liquidation parameters
• Interest rate models
• Borrowing caps

Current target curators: Block Analitica, Re7 Capital, MEV Capital. Each must be engaged and negotiated with separately.

Status: Phase 2 roadmap, active engagement.

1. Investor holds ERC-3643 Tortuga tokens on a live chain (Plume, Base, or Canton)
2. Investor deposits tokens into a Morpho Blue pool that has been curator-approved for Tortuga tokens
3. The pool contract address is registered in the ERC-3643 Identity Registry (whitelisted as an eligible holder — required for the deposit transfer to execute)
4. Investor borrows USDC against deposited tokens at curator-defined LTV (e.g., 70% of token NAV)
5. Investor retains token yield: coupon distributions continue to flow to the token holder of record while tokens are deposited in the pool

When a Tortuga token is deposited into a Morpho Blue pool, the pool contract address must be a registered Identity Registry address. Tortuga's compliance layer handles this registration.

If tokens are liquidated, the liquidator's wallet must also be registered. This constrains liquidation participants to verified counterparties — materially different from unpermissioned DeFi where any address can execute a liquidation.

Curator-defined liquidation, not algorithmic oracle-triggered liquidation, is the intended model.

For how ERC-3643 compliance enforcement works in DeFi contexts, see compliance-layer.md.

Token NAV is computed off-chain using PwC-validated pricing models and recorded on-chain periodically. This on-chain NAV record is the basis for collateral valuation in curator-configured lending pools. Curators define the haircut applied to NAV when setting LTV.

For NAV methodology and PwC validation, see ../product/pricing-methodology.md.

All DeFi integration is additive — the underlying bond, Luxembourg securitization vehicle, Swiss ISIN, and PwC-validated pricing framework remain intact.
