Fusion Introduction

What IPOR Fusion is, who this documentation is for, and how onchain and offchain responsibilities split between vaults and Alphas.

What is Fusion?

IPOR Fusion is an institutional-grade asset management infrastructure for automated execution. It is an unopinionated and customizable framework that asset managers can use to deploy assets onchain while implementing custom algorithms offchain.

Functioning as a universal integration layer, the protocol utilizes a modular vault architecture to connect with the entire DeFi ecosystem. Complex cross-protocol interactions are routed through isolated, standardized adapter contracts known as "Fuses." This composable design allows builders to bundle multiple operations into a single, atomic execution, abstracting the technical overhead of managing diverse protocol interfaces.

It can be considered the Prime Brokerage Protocol of DeFi. From a TradFi asset manager's perspective, Fusion is a single entry point for the integration, coordination, monitoring, execution, and accounting of sophisticated DeFi strategies.

The protocol clearly separates concerns between onchain state and offchain computation:

• Onchain components: Smart contracts enforce transparent asset allocation, strict risk limits, and verifiable accounting.

• Offchain execution: External agents (called "Alphas") execute strategy operations based on parameters and logic configured by vault managers (called "Atomists").

Who is this documentation for?

This section provides technical specifications and integration guides for anyone building on or interacting with the Fusion ecosystem. The primary audience includes:

• Vault Managers (Atomists) & Risk Managers configuring market substrates, exposure limits, and role-based access controls.

• Backend Developers building offchain execution agents (Alphas).

• Smart Contract Engineers integrating new protocols via the Fuse architecture.

• Integrators connecting external applications to Fusion's ERC4626 vault interfaces.
