I. The 4-Layer RWA Stack for Institutions

To ensure the seamless mapping of assets from the physical world to the digital realm, LIMA employs a standardized, modular four-layer technology stack:

1. Application & Trading Layer: Compliant DEXs, lending markets
2. Compliant Token Standard Layer: ERC-3643 / Permissioned
3. Oracle & Data Verification Layer: Chainlink PoR, ZK-KYC
4. Legal & Physical Asset Layer: SPVs, custodian banks, law firms

Layer 1: Legal & Physical Custody Layer

Legal Structure: Assets (such as U.S. Treasuries or real estate) are held within independent Delaware or Colorado SPVs (Special Purpose Vehicles), protected under the U.S. Uniform Commercial Code (UCC).
Segregated Custody: Cash and securities are held by compliant Tier-1 custodian banks (e.g., BNY Mellon), while physical real estate titles are registered with top-tier title insurance companies.

Layer 2: Oracle & Data Layer

Proof of Reserve (Chainlink PoR): Oracles periodically fetch actual asset and liability balances from custodian bank accounts and generate tamper-proof cryptographic proofs on-chain.

Zero-Knowledge Identity Verification (ZK-KYC): Investors demonstrate their accredited investor status to the blockchain via zero-knowledge proofs, ensuring privacy protection while complying with SEC KYC/AML regulations.

Layer 3: Permissioned Token Standard Layer

ERC-3643 Standard: LIMA eschews the permissionless standard ERC-20 in favor of the ERC-3643 protocol, which is specifically designed for compliant assets.

Code-Level Compliance Controls: Only wallet addresses authorized via the compliant identity registry (ONCHAINID) are permitted to hold or receive the token. If an unauthorized address attempts to receive assets, the smart contract will automatically reject the transaction at the code level.

Layer 4: Application and Liquidity Layer

Tokenized assets (such as the LIMA-US T-Bill Token) can serve as high-quality collateral within authorized decentralized lending protocols or be traded with sub-second settlement in compliant dark pools.

II. Core Design Principles of RWA Tokenomics

Unlike pure governance tokens—which are vulnerable to inflation and sell-offs following lock-up expirations—the tokenomics of institutional-grade RWAs must adhere to the following golden rules:

100% Real Yield Backing: Token yields are derived entirely from interest, rent, or cash flows generated by the underlying assets; they never rely on unconstrained token issuance to fabricate high returns.

Deflationary and Auto-Burn Mechanisms: When investors choose to redeem underlying assets, the smart contract automatically burns the corresponding number of tokens, maintaining a precise 1:1 peg between the on-chain token supply and the actual off-chain assets at all times.

Liquidation Priority Mechanism: In extreme market conditions, the RWA smart contract employs built-in automated liquidation logic, ensuring that token holders possess priority claims on the SPV’s underlying assets.

III. LIMA Global’s Institutional Gateway

To accommodate the existing IT and compliance infrastructures of institutional clients, LIMA offers a streamlined “Web2.5” integration experience:

Institutions can connect seamlessly via API and compliant MPC (Multi-Party Computation) custody services, eliminating the need to manage complex private keys directly.

Billing and tax reporting automatically integrate with mainstream ERP systems (such as SAP and NetSuite) and traditional fund accounting systems, effectively bridging the technological divide between traditional finance and the on-chain world.

Breaking down technical barriers, aligning code with the rule of law, and directing liquidity toward value—this is the RWA digital infrastructure built by LIMA Global.
