Layer 02 — Logic Layer

Logic & Composability:
The Financial Operating System

Programmable finance isn't just about moving tokens; it's about encoding the rules of finance directly into the infrastructure. Through Smart Contracts, legal obligations become executable code, replacing human middle-men with immutable, audited logic.

01 From Information to Execution

In the legacy world, a financial contract is a PDF — a passive information object that requires human and bank systems to interpret and act upon. In the PCM framework, a contract is an active execution object.

Financial Execution Flow

Visualizing the automated lifecycle of a financial asset on the Unified Ledger: from coupon triggering to final settlement.

    require(bond.isCompliant(msg.sender), "KYC fail");

6 Applications of Programmable Logic in DCM

Automated Coupons

Automatic payment to holders on dates defined in the contract. Zero reconciliation, zero delays, zero errors.

On-Chain KYC Compliance

Identity and regulatory eligibility verification integrated directly into the transfer logic (ERC-3643 / T-REX).

Dynamic Collateralization

Automatic adjustment of collateral margins based on on-chain valuations — programmed margin calls.

Automated Reinvestment

Reinvestment of coupon flows into new instruments according to predefined portfolio rules — without a manager.

Regulatory Reporting

Automatic generation of EMIR / MiFID II / DORA reports integrated into the instrument lifecycle — native auditability.

Redemption & Burn

At maturity, the principal is automatically returned and the bond tokens destroyed — closed-loop without intervention.

BIS Reference — Unified Ledger 2023

The BIS report "Blueprint for the future monetary system" (2023) positions the Logic layer as the fundamental differentiator of the Unified Ledger compared to first-generation DLT systems. Conditional programmability — automatic execution if and only if all regulatory conditions are met — is described as "the most profound transformation of financial mechanics since dematerialization."
