Service: RWA Tokenization Engine ​

The RWA Tokenization Engine provides the core infrastructure rails for modern capital markets, transforming traditional assets into compliant, liquid, digital products. It addresses the fundamental problems of legacy issuance—high costs, manual processes, slow settlement, and opaque data—by automating the entire asset digitization lifecycle. It orchestrates the entire process of taking an off-chain asset and transforming it into a fully structured, on-chain-ready offer.

This engine is built on five key pillars:

  • Structural Integrity: Ensures every offer is created with a complete and valid set of financial terms, legal documents, and compliance rules.

  • Dynamic Configuration: Adapts its logic and data requirements based on the specific type of asset, security, and regulation being used.

  • On-Chain Integration: Seamlessly prepares all necessary parameters for smart contract deployment and orchestrates the creation of the on-chain asset.

  • Compliance by Design: Bakes in the rules for investor eligibility and share management from the moment an offer is created.

  • Secure Document Association: The engine integrates with the Filer to securely upload and associate all required legal and marketing documents.

  • Efficiency & Cost Reduction: Streamlines issuance via templates and automation, making smaller deals economical and reducing operational overhead.

  • Programmability & Automation: Creates "smart securities" with built-in rules for compliance, distributions, and lifecycle events, enabling atomic settlement and T+0 operations.

  • Transparency & Data Integrity: Establishes the digital twin of the asset, laying the foundation for live disclosures and verifiable, machine-readable data.

Core Technical Components & APIs ​

This engine is the primary creator and manager of the offer and its on-chain counterpart, orchestrating several core components:

Primary Models:

Governing Logic:

  • Offer Status Lifecycle: The engine is responsible for an offer's progression through its initial states.

  • Global Business Rules: It enforces rules related to offer creation, such as share calculation and financial data integrity.

The Process Lifecycle & Key Capabilities ​

The engine manages the tokenization process through distinct phases and ongoing capabilities.

Phase 1: Asset Structuring & Configuration ​

This phase provides the tools for issuers to define the asset and its terms within a compliant framework.

  • Templatized Structuring: Offers flexible modules within the Issuer Portal to structure diverse asset classes (debt, equity, funds, real estate, etc.), including defining the legal vehicle and associated terms/covenants.

  • Financial Modeling: Provides the framework for defining and validating core financial terms (total shares, price per share, minimum investment), ensuring consistency.

  • Compliance Rule Configuration: Integrates with the Regulatory Compliance Engine to allow issuers to select and configure applicable compliance rules (residency, investor type, lockups, transfer restrictions) that will be embedded in the token.

  • Document Association: Integrates with the Filer to link all necessary legal agreements, disclosures (PPM/Offering Circular), and asset documentation to the offer record.

  • Ledger Initialization: The engine establishes the share ledger for the offer, setting the initial counters for subscribed shares and confirmed shares to zero.

  • Yield Mechanism Definition: Based on the offer's financial structure, the engine sets the economic_model (which will be stored on the EVM Contract record):

    • If PRICE_APPRECIATING (Growth Model): The engine configures the smart contract to function as an accrual token (e.g., like a cToken). The contract will be designed to automatically reinvest all generated yield, causing its internal exchange rate to rise.

    • If DIVIDEND_PAYING_BATCH (Periodic Income Model): The engine configures the contract as a standard, pegged-price token. This prepares it for the Smart Dividends Service, which must be used by an administrator to execute all periodic payouts.

    • If DIVIDEND_PAYING_STREAMING (Continuous Income Model): The engine configures a specialized "streaming" smart contract (e.g., a rebasing token). The contract is designed to receive yield and automatically distribute new tokens to holders in real-time.

Phase 2: Programmable Smart Contract Generation & Deployment ​

Transforms the off-chain structure into an executable, on-chain digital asset.

  • Smart Contract Generation: Based on the configured terms and compliance rules, and selected economic_model, the engine automatically generates or parameterizes the appropriate smart contract code (e.g., EIP-3643 compliant). This includes embedding logic for distributions, potential vesting/amortization, and transfer controls.

    • If DIVIDEND_PAYING_BATCH, it deploys a standard token contract, awaiting calls from the Smart Dividends Service.

    • If DIVIDEND_PAYING_STREAMING, it deploys a contract with the real-time minting/distribution logic built-in.

    • If PRICE_APPRECIATING, it deploys a contract with the yield-reinvestment and exchangeRate logic built-in.

  • Deployment Orchestration: Upon final approval of the offer, the engine calls the evm-api via a simplified interface (potentially "no-code" in the Issuer Portal) to deploy the configured smart contract to the selected blockchain network.

  • Record Linking & Initialization: Creates the EVM Contract record, storing the contract's address and its economic_model, establishing the permanent one-to-one link back to the offer. It initializes the on-chain state (e.g., minting total supply to a treasury address).

Ongoing Capabilities ​

Once the tokenization process is complete, the engine continues to perform critical function - real-time subscription management, which is triggered by events from the Investment Process Management Service.

  • Subscription Logic:

  • Over-Subscription Prevention: The engine blocks the creation of new Investments if the requested number of shares would cause the total subscribed shares to exceed the total shares available for the offer.

  • Non-Investable Leftovers Rule: The engine enforces logic that dynamically adjusts the minimum investment amount when an offer is nearing full subscription, ensuring it can be completely sold out.

Advanced Scenarios & Platform Resilience ​

The engine includes validation and error handling to ensure the integrity of every offer.

  • Configuration Validation: The engine performs a comprehensive validation check before an offer can be submitted for legal review. It blocks any submission with inconsistent or missing data.

  • Deployment Failures: If the evm-api call to deploy the smart contract fails, the engine will prevent the offer's status from advancing. It will log the error and keep the offer in a state where an administrator can retry the deployment.

  • Offer Updates: When an administrator edits an offer in the DRAFT status, the engine re-runs all validation checks upon saving to ensure its continued integrity.

  • Immutable Record Keeping: Ensures that once deployed, the core parameters linking the offer to the EVM Contract are immutable, providing an auditable connection.
