Fusion Prime is an omnichain collateral and settlement protocol for digital-asset treasuries. It unifies cross-chain collateral, oracle-priced risk, and programmable settlement into one layer — so an institution can deposit collateral on one chain and borrow against it on another, with settlement and compliance handled end to end.
Note
Project status. Active development. The cross-chain vault, bridge-adapter layer, and the event-driven backend services are implemented and tested locally and on testnets. There is no production deployment, and no external security audit has been performed — this is engineering-in-progress, not a live venue. See Architecture and Testing for technical detail.
The 2025–2026 institutional on-chain wave has a common shape: moving collateral and settlement on-chain. Stablecoin settlement volume overtook ACH; tokenized treasuries crossed tens of billions; and cross-chain messaging became bank infrastructure — Chainlink CCIP now underpins interbank tokenized-settlement pilots. Fusion Prime is built around exactly that thread: a vault whose collateral and risk move across chains through a bridge-agnostic adapter layer.
A modular architecture designed for reliability and independent scaling.
The core is a CrossChainVault: collateralized positions, an interest-rate model,
oracle-fed pricing with staleness handling, and health-factor liquidations. Cross-chain
messaging runs through a BridgeManager + pluggable adapters design — Chainlink
CCIP first (the institutional interoperability lane), with Axelar as an alternate
adapter. The abstraction is the point: the protocol is not wed to any single bridge
vendor. On the hardening roadmap: per-source trusted-remote allowlists and replay
protection on the inbound message path.
Independently scalable backend services around the vault:
- Settlement Service — orchestrates multi-party settlement flows.
- Risk Engine — collateralization and portfolio-health assessment.
- Compliance Service — identity verification and AML monitoring.
- Event Indexer / Relayer — sync between on-chain state and off-chain services.
Type-safe SDKs for integration:
- TypeScript / React SDK — wagmi-powered hooks and React contexts for web apps.
- Python SDK — for treasury automation and settlement workflows.
A dashboard built with React, TypeScript, and Tailwind CSS, with Recharts for risk visualization.
The services are designed for a serverless cloud foundation — Cloud Run for orchestration, Cloud SQL (PostgreSQL) for transactional data, Pub/Sub for asynchronous messaging. Environments are provisioned ephemerally (apply → validate → destroy) rather than run continuously; there is no standing production deployment.
A collateral layer that aggregates assets across Ethereum and its L2s (Base first) and moves collateral state cross-chain, presenting a unified borrowing position.
Multi-party programmable escrow for OTC-style settlement. Funds release on verifiable on-chain triggers or identity-registry approvals.
Continuous tracking of collateralization ratios and margin requirements, driven by oracle prices with explicit staleness handling.
A security-first engineering culture:
- Foundry suite — unit, fuzz, and invariant testing for the contracts; invariants protect vault accounting.
- Symbolic execution — Halmos proofs over critical contract invariants.
- Multiple static analyzers — Slither and Aderyn in CI on every contract change, plus mutation testing to check the suite's own strength.
- Python pytest — unit and integration tests across the microservices.
- End-to-end simulation — cross-chain and settlement flows on local Anvil and testnets.
No external audit has been performed. This code is not intended for use with real funds in its current state.
- Cross-Chain Interoperability — a bridge-agnostic adapter layer (CCIP-first, Axelar-capable) that abstracts cross-chain messaging away from the application.
- Real-World Asset collateral — designed to extend to tokenized treasuries and other RWA collateral, the fastest-growing institutional on-chain segment.
- Self-Sovereign Identity — ERC-734/735 so institutions manage their own KYC/AML credentials without a centralized intermediary.
- Programmable Finance — settlement logic as verifiable code rather than trust-based process.
