STONE BRIDGE is a decentralized CDP (Collateralized Debt Position) protocol designed to transform real estate ownership rights into liquid assets.
Unlike traditional bank lending, the protocol eliminates the time value of money (0% interest rate), replacing it with a one-time architectural minting fee.
02. TECHNICAL STACK: STONE DS-PROTOCOL
We adapt the Securitize DS Protocol logic for the TON blockchain.
2.1. Trust Service (Permissions)
Manages access via TON smart contracts. Role 2 (Nodes) are legal validators authorized to verify Electronic Mortgages via SmartDeal API.
2.2. Registry Service (Asset Ledger)
Links TON wallets to property identifiers. Asset-NFT (SBT) acts as a mirror, containing hashed EGRN data.
2.3. Compliance Service (Validation)
Restricts Asset-NFT transfers until debt is repaid. Initiates recovery via Reserve Fund in case of default.
03. FINANCIAL MECHANICS (CDP 80/20)
LTV: 80% (CADASTRAL)
INTEREST RATE: 0%
STABILITY FEE: 20%
LOAN ASSET: $STONE
The protocol fixes debt in STONE nominal value. With 10% annual inflation, the real value of the debt is halved in ~7 years, creating an "Inflationary Leverage" for the borrower.

05. LEGAL BRIDGE: OFF-CHAIN TO ON-CHAIN
The protocol uses a hybrid scheme: Electronic Mortgages (RU Legal Framework) + SmartDeal API + TON Blockchain. Verification is conducted by distributed legal nodes, eliminating central bank corruption.
