# Architecture Overview

- [General](https://docs.ipor.io/build-on-fusion/architecture-overview/general.md): High-level map of the Fusion architecture: how vaults, fuses, Atomists and Alphas fit together.
- [What is a Fusion vault?](https://docs.ipor.io/build-on-fusion/architecture-overview/what-is-a-fusion-vault.md): The Plasma Vault's implemented standards (ERC-4626, ERC-20, OZ Votes, Access Manager), redemption delay, rewards, fees and configuration surface.
- [What is a Fuse?](https://docs.ipor.io/build-on-fusion/architecture-overview/what-is-a-fuse.md): What a Fuse is, how it adapts vault calls to an external protocol, and the fuse whitelist registry.
- [What is an Atomist?](https://docs.ipor.io/build-on-fusion/architecture-overview/what-is-an-atomist.md): The Atomist role: who configures a vault's risk and market boundaries.
- [What is an Alpha?](https://docs.ipor.io/build-on-fusion/architecture-overview/what-is-an-alpha.md): The Alpha role: who executes strategy transactions within an Atomist's configured boundaries.
