Safety and security nets are in place while Portrait is in beta. Read more about the security measures in place.

Smart Contracts

The Portrait Protocol is powered by a collection of smart contracts that manage the core interactions between users and the Portrait Protocol. The smart contracts are divided into several categories, each responsible for a specific aspect of the protocol. The smart contracts are designed to be modular and upgradable, allowing for easy maintenance and upgrades.

Overview of Smart Contracts

Open Source

To ensure transparency and security, the smart contracts are licensed under the MIT License. The contracts are available on GitHub.

Modularity and Upgradability

The contracts are designed to be modular and upgradable. The core contracts follow the UUPS standard, allowing for easy upgrades and maintenance. Furthermore, the contracts are compliant with account abstraction, building on top of the EIP-6492 standard.

Core Contracts

The core contracts are responsible for managing the core interactions between users and the Portrait Protocol.

Contract	Objective
`PortraitIdRegistry`	Manages the unique identifiers associated with a Portrait.
`PortraitNameRegistry`	Manages the names associated with a Portrait.
`PortraitAccessRegistry`	Manages the access control associated with a Portrait.
`PortraitPlanRegistry`	Manages the plans associated with a Portrait.
`PortraitNodeRegistry`	Manages the hosting nodes associated with a Portrait.
`PortraitStateRegistry`¹	Manages the latest data associated with a Portrait.

Libraries and Utils

The libraries and utils are used by the core contracts to provide additional functionality and security.

Library/Util	Description
`PortraitSigValidator`	Validates the signatures associated with a Portrait.
`UniversalSigValidator`	Validates account abstraction signatures, forked from the EIP-6492 standard.

Deployed Contracts

All contracts have been deployed on the Base Sepolia testnet.

Footnotes

The PortraitStateRegistry contract will be deprecated in the future in favor of the state returned by hosting nodes. ↩
