Digital Bond Blueprint | DCM Core Standards

Executive Architecture

This blueprint assumes a hybrid institutional stack where legal term sheets are digitized via oracles and bridged to regulated DLT environments (Public-Permissioned or Private).

Legacy Systems
Internal Ledger / ERP

DCM GTDS Layer
Standardized Metadata

Smart Contract
ERC-3643 / TREX

Implementation Note: The standard ensures that the Asset_Metadata stored on-chain acts as the "Golden Record", synchronized with traditional CSD (Central Securities Depository) records for legal finality.

GTDS Data Mapping

Mapping traditional financial identifiers to the DCM Global Token Data Standard (GTDS).

Financial Data Point	GTDS Field	DLT Mapping Type
International Securities ID	gtds_isin	String (Off-chain Registry Ref)
Annual Coupon Rate	gtds_coupon_bps	Uint256 (Basis Points)
Maturity Date	gtds_maturity_ts	Epoch Timestamp
Currency Identifier	gtds_ccy_iso	ISO-4217 (TFIN-MONY Ref)
Wholesale Liquidity Provider	gtds_agent_id	DLT Address / ENS

Lifecycle Interaction Logic

// Digital Bond Coupon Payment Trigger (Abstraction)

function executeCouponPayment(bondId) {
  if (block.timestamp >= registry[bondId].nextCouponDate) {
    amount = calculateBps(registry[bondId].notional, registry[bondId].coupon_bps);
    settlement.triggerAtomicPayment(holders[bondId], amount, registry[bondId].ccy);
    registry[bondId].nextCouponDate += 365 days;
  }
}

This logic ensures that payments are triggered directly by the smart contract assets upon reaching the gtds_maturity_ts or coupon dates, eliminating manual reconciliation.
