The Protocol That Eliminates Counterparty Risk

TQC Vault

Self-Custody Lending Infrastructure

This page describes the same TQC Vault system from a more technical and conceptual perspective. It focuses on the lending model and enforcement logic without exposing implementation details.


Lending Model Overview

TQC Vault enables lending by enforcing collateral constraints directly at the asset level.

A borrower commits collateral to a vault under explicit conditions defined at the outset of the agreement. These conditions govern how and when the collateral can be released. Validators evaluate proposed state changes and approve them only when the predefined conditions are satisfied.

During the lock period, transactional control is restricted by the system. Custody and ownership remain with the borrower. No participant, including lenders or validators, has unilateral authority to override the enforcement rules.


Mortgage Analogy

The Vault can be understood using a familiar secured lending analogy.

In a mortgage, a borrower pledges property as collateral. Ownership remains with the borrower, but the property is encumbered until the loan terms are satisfied. Enforcement typically relies on legal processes.

In TQC Vault, crypto assets are pledged under predefined rules. Enforcement is handled by validators and system constraints rather than courts, custodians, or legal escrow. Outcomes are determined by rule satisfaction, not discretion.


Enforcement Boundaries

The Vault enforces collateral constraints only.

It does not:

These functions exist outside the Vault and are intentionally excluded from scope.


Validator Governance

At a high level, enforcement operates as follows:

The system does not depend on off-chain discretion, fiat escrow, or institutional custody to function.


MVP Scope

The Vault MVP validates the enforcement primitive.

It demonstrates that self-custody collateral locking can be enforced through validator governance and crypto-native mechanisms.

It does not claim full automation, trustlessness, or cross-chain orchestration. Those capabilities, if pursued, exist at higher system layers.


Relationship to Other Systems

TQC Vault enforces collateral constraints.
TQC Custody enforces title transfer and settlement.

They are complementary systems with distinct roles and boundaries.
