Smart Bond Contracts

Beyond simple tokenization, the Smart Bond Contract (SBC) acts as the operational brain of the debt instrument, merging terms, workflows, and settlement logic into a single ledger entry.

Single Source of Bond Data

By housing both static data (legal terms) and dynamic state (coupon balances) in a single contract, market participants eliminate the need for cumbersome reconciliations between multiple systems.

Orchestrated Lifecycle Automation

The SBC automatically manages the transition through the 8 stages of the bond lifecycle, ensuring that corporate actions, interest payments, and redemptions occur instantaneously upon trigger events.

// Conceptual Smart Bond Logic v1.0.ddcm
contract SmartBond {
  // Global identifiers
  string public isin = "DZB-2026-TOKEN";
  uint256 public maturity = 1.1124800;

  // Automated Coupon logic
  function triggerCouponPayment() external {
    require(block.timestamp >= nextCouponDate);
    settlePayment(investorRegistry, amountPerToken);
  }
}

Modular Multi-Ledger Support

Modern SBC architectures prioritize interoperability, allowing the bond logic to interact with external cash ledgers (Wholesale CBDC, stablecoins) for atomic Delivery vs. Payment (DvP).
