"When the code cannot lie, humanity no longer needs to."
ProjectUSD is a fully on-chain, algorithmic monetary system designed for PulseChain.
It achieves economic stability without banks, without governance, without oracles,
and without centralized intervention of any kind.
It represents the next evolution of decentralized finance:
a self-regulating economic engine powered solely by transparent, immutable logic.

ProjectUSD is built from five immutable core modules:
- VaultEngine – Collateral, debt, and CR logic
- Controller – Autonomous equilibrium engine (R & r-epochs)
- Oracle – Medianized, deviation-safe pricing
- Liquidation & Redemption Engine – Stability enforcement
- StabilityPool – Collective risk absorption
The “Oracle” module in ProjectUSD is not an external price oracle.
It does not use Chainlink, Pyth, DIA, APIs, or any off-chain data.Instead, it is a pure on-chain TWAP reader that derives price information
exclusively from the ProjectUSD/PLS AMM pool on PulseChain.
- no external dependencies
- no governance updates
- no admin intervention
- fully deterministic and on-chain
This ensures that ProjectUSD remains an autonomous, oracle-free monetary system while still allowing the controller to observe its own AMM-based market behavior.
A detailed architectural explanation is available at:
➡ /Architecture/README.md
For developers, auditors, and researchers who want to enter directly into the technical foundations of ProjectUSD, the following documents serve as the primary entry points:
➡ /Architecture/README.md
A high-level introduction to the system architecture, core modules, and internal data flows.
➡ /Architecture/specs/README.md
The formal, audit-ready specifications of all core components:
- VaultEngine
- Controller
- Oracle
- Liquidation & Redemption
- StabilityPool
- Security
- Governance & Freeze
- KPI Subgraph
- Incident Runbook
➡ /Developer_Playbook/README.md
A practical guide for development workflow, standards, conventions, and recommended best practices.
➡ /Glossary.md
Definitions of terms, mechanisms, variables, economic concepts, and formula notation used throughout the system.
ProjectUSD contains one of the most complete SPEC frameworks in decentralized finance:
➡ /Architecture/specs/README.md
➡ /Architecture/specs/README.de.md
This section provides the entire audit-ready blueprint of the system, including:
- VaultEngine SPEC
- Controller SPEC
- Oracle SPEC
- Liquidation & Redemption SPEC
- StabilityPool SPEC
- Security SPEC
- Governance & Freeze SPEC
- Freeze Checklist
- KPI Subgraph SPEC
- Incident Runbook
- DEX-LP SPEC (optional)
All specifications are modular, consistent, and available in English and German.
ProjectUSD provides two curated document collections that extend beyond the technical specifications and deepen the economic foundations of the system.
➡ /Articles
Analytical essays and conceptual papers covering topics such as:
- internal value units and purchasing power
- the meaning of the name ProjectUSD
- the P R r model
- theoretical principles of autonomous monetary systems
These texts provide the conceptual framework behind the design and help explain the reasoning that informs the SPECS.
➡ /Studies
Formal research studies covering subjects such as:
- stability mechanisms and anti reflexivity
- system game theory
- collateral models and stress simulations
- liquidity and arbitrage behaviour
- long term surplus development
- gas usage and efficiency models
These studies offer quantitative models, simulations and deeper analytical insights into system behaviour.

This repository contains the official ProjectUSD specifications only.
Smart contract implementations may be developed by independent teams. Whether a specific implementation is secure can only be evaluated through:
- open audits,
- peer review,
- open-source transparency,
- formal verification,
— not through this document.
ProjectUSD does not publish smart contracts and does not designate any implementation as official.
Users should rely only on implementations that have undergone verification by reputable auditors and whose source code is fully transparent.
