A new layer of financial sovereignty

NEXUS Finance is a deterministic credit infrastructure protocol that brings institutional-grade rigor to decentralized finance. Every mint, every liquidation, every governance decision is governed by cryptographic proof.

Overcollateralized Credit

NXUSD issuance requires 150%+ collateral ratio. Automatic liquidation at 130% protects protocol solvency at all times.

◈

Deterministic Engine

Every risk decision by the NEXUS-120 engine produces an immutable hash-chained receipt — audit-grade, forever verifiable.

⬡

Governance-Hardened

Role-based access control. Multisig Safe administration. Guardian pause. Zero single points of failure.

Protocol Flow

How it works

A closed-loop system where every action is governed, recorded, and cryptographically verified.

Deposit Collateral

User deposits ETH into the VaultManager. Oracle module validates price via Chainlink with staleness check.

ETH → Vault

Engine Validates

NEXUS-120 evaluates capital adequacy, liquidity, and risk lattice. Produces signed ALLOW/DENY verdict with receipt hash.

CCR ≥ 1.05

NXUSD Minted

If verdict is ALLOW and ratio ≥ 150%, NXUSD is minted. Max 66% of collateral value. Receipt appended to audit trail.

NXUSD ← Mint

Auto-Liquidation

If collateral ratio drops below 130%, the keeper bot executes liquidation. 5% bonus incentivizes keepers to act fast.

Ratio < 130%

Architecture

Built for institutions

Five sovereign pillars govern every protocol decision. Capital adequacy law, treasury constitution, adversarial suite, risk lattice, and economic constitution — each producing deterministic, hash-chained proof of compliance.

⬡

Capital Law

CCR ≥ 1.05, LCR ≥ 1.0, leverage ≤ 95%. Hard enforcement — no exceptions, no overrides.

SOV_003

◈

Treasury Constitution

4 tranches: Operating, Liquid, Core, Backstop. Waterfall model. Outflow freeze on treasury fail.

SOV_004

△

Risk Lattice

5-year stress simulation across 5 axes: liquidity, peg shock, NAV haircut, leverage, correlation.

SOV_005

⚠

Adversarial Suite

6 attack scenarios: tamper, replay, double-finalization. Hardened against all known vectors.

SOV_002

Economic Constitution

Monetary policy rules governing issuance caps, fee schedules, and systemic limits. Immutable by design.

SOV_006

∞

Audit Trail

Every decision produces a SHA-256 receipt. JSONL append-only log. Hash-chained — one tampered entry breaks the entire chain.

Version Tags

Deterministic versioning. Each tag corresponds to a signed engine receipt bundle.

Attack Scenarios

Tamper, replay, double-finalization, and 3 more. All adversarial vectors hardened.

150%

Min Collateral Ratio

Hard floor. VaultManager rejects any mint that would breach this threshold.

Stress Axes (5Y)

Liquidity, peg shock, NAV haircut, leverage, correlation — all stress-tested simultaneously.
