REBEKA is an institutional-grade RWA infrastructure designed to bridge traditional real estate with on-chain liquidity, solving the two biggest barriers for institutional capital: legal certainty and financial privacy. By leveraging Arbitrum’s high-performance network, we provide a secure framework backed by Mexican Irrevocable Trusts (Fideicomisos). Our protocol introduces two core technological breakthroughs: * The Sovereign Permissioned Layer: A native compliance engine built directly into our Arbitrum smart contracts. Token transfers are strictly restricted to KYC/AML-verified wallets. If a wallet lacks legal authorization, the smart contract automatically reverts the transaction. * Institutional Privacy (Confidential-by-Design): To meet traditional banking privacy standards, we integrated Fully Homomorphic Encryption (FHE) via Fhenix. Investor balances and transaction amounts remain mathematically encrypted (as ciphertext) on the public block explorer, ensuring total confidentiality. Finally, REBEKA is future-proofed for global liquidity. In our next phase, we are integrating LayerZero’s cross-chain messaging to evolve into an omnichain protocol, attracting capital from any network while maintaining Arbitrum as our definitive source of legal truth.
The Problem: A Two-Sided Illiquidity Crisis Real estate remains one of the most illiquid asset classes globally, and the market is broken for both sides:
For Property Owners: Families and developers hold massive, highly valuable plots of land but face a "frozen asset" crisis. Finding a single buyer with enough liquidity for a large-scale acquisition is incredibly difficult and slow.
For Institutional Investors: Capital wants to enter the Web3 Real World Asset (RWA) space but faces two deal-breaking barriers: lack of true legal backing (who actually owns the asset?) and zero financial privacy on public ledgers. Furthermore, traditional DeFi protocols cannot enforce the strict KYC/AML compliance required by law.
The Solution: REBEKA REBEKA is an institutional-grade infrastructure built on Arbitrum that professionalizes land tokenization. We bridge the gap between traditional legal certainty and Web3 liquidity.
Every asset on our platform is legally backed by a Mexican Irrevocable Trust ("Fideicomiso"), the ultimate legal vehicle for property protection. To bring this securely on-chain, we built two core technological pillars:
The Sovereign Permissioned Layer: We developed a native compliance engine embedded directly into our smart contracts. Token transfers are strictly restricted to whitelisted wallets authorized by the legal Trust. If a user hasn't passed KYC, the smart contract automatically blocks the transaction (revert). It’s not a simple visual filter on the frontend; it is the law written directly into code.
Institutional Privacy (FHE): To meet the strict privacy standards of traditional banking, we integrated Fully Homomorphic Encryption (FHE) via Fhenix. Unlike standard ERC20 tokens, REBEKA ensures that investment amounts and token balances remain completely hidden (encrypted as ciphertext) on the public block explorer. This makes our protocol "Confidential-by-Design."
Why Arbitrum & The Omnichain Future? REBEKA leverages Arbitrum’s high-performance, low-cost settlement layer to make fractional ownership viable and secure.
Furthermore, because global liquidity shouldn't have borders, our architecture is future-proof. In our next phase, we are integrating LayerZero’s cross-chain messaging technology to evolve into an omnichain protocol. This will allow us to attract capital from any network, while always keeping Arbitrum as our single source of legal truth.
Progress During Buildathon During the Arbitrum Buildathon, our team transitioned REBEKA from a conceptual legal-tech model into a highly advanced, privacy-preserving technical prototype. Our core technical achievements include: 1. The Sovereign Permissioned Layer (Smart Contracts) * Native Compliance Engine: We developed the core token logic on Arbitrum using a custom Permissioned ERC-20 standard. Asset ownership is restricted directly at the smart contract level. * Execution: We successfully programmed the contracts to automatically block (revert NotAllowed) any transfer attempt from/to a wallet that hasn't passed the Mexican Trust's KYC validation, eliminating the need for weak off-chain filters. 2. Institutional Privacy Integration (Fhenix & FHE) 🚀 Major Breakthrough * Confidential-by-Design: This was our biggest technical leap. We successfully integrated Fully Homomorphic Encryption (FHE) via Fhenix into our Arbitrum smart contracts. * Live Deployment: We deployed the $RWC1 (RWA Confidential) token on Arbitrum Sepolia. As proven on the block explorer, our integration successfully masks sensitive financial data, encrypting investment amounts and token balances as unreadable Ciphertext while still validating the math on-chain. 3. Frontend Prototyping & dApp Integration * Institutional UI: Developed a professional investor gateway that connects directly to our Arbitrum smart contracts. * Live States: The frontend successfully demonstrates the real-time execution of our permissioned layer, providing a seamless checkout for authorized wallets while properly handling and displaying "Access Denied" states for non-KYC users. 4. Legal-Technical Architecture & Governance * Fideicomiso Alignment: Bridged our on-chain logic with the strict physical and legal requirements of a Mexican Irrevocable Trust. * Omnichain Foundation: Established the foundational architecture to integrate LayerZero's cross-chain messaging in our immediate next phase.
We are currently raising our initial Seed Round (Oxygen Fund) to transition the REBEKA infrastructure from a testnet prototype to a fully operational, production-ready protocol on Arbitrum Mainnet. This capital is focused on the legal-technical engineering required to securely bridge institutional capital with Web3. Capital Allocation & Objectives: * Legal & Compliance Infrastructure: Constitution of the initial physical Mexican Irrevocable Trusts (Fideicomisos) and rigorous security audits for our Sovereign Permissioned Layer smart contracts. * Privacy Implementation (FHE): Scaling our Fully Homomorphic Encryption (Fhenix) integration from testnet to mainnet, ensuring production-grade confidentiality for institutional investors' data. * Omnichain Expansion: Funding the development and integration of LayerZero’s cross-chain messaging architecture to attract borderless liquidity, while maintaining Arbitrum as our primary legal and settlement layer.
