Overview

Portfolio is an automated market making protocol for creating custom liquidity distribution strategies at the lowest cost possible. Each pool in Portfolio can be created with a default strategy or custom strategy that defines a trading function, determining the available prices offered by the provider's liquidity. These pools all exist within the single Portfolio smart contract resulting in significantly lower gas costs for liquidity providers and swappers.

Read the local docs, hosted docs docs.primitive.xyz, or the formal specification for more information.

Important:

• This codebase uses the FORGE formatter. This is not prettier. If you have not already, make sure if you use vs code that the formatOnSaveconfig variable uses forge fmt instead of prettier.
• Setup the proper settings using this guide: forge fmt for formatOnSave vscode.

When making a pull request:

• All tests pass.
• Code coverage does not change.
• Code follows the style guide:
  • Follows Primitive styling rules.
  • Run forge fmt.
  • Code is thoroughly commented with natspec where relevant.
• If making a change to the contracts:
  • Gas snapshots are provided and demonstrate an improvement (or an acceptable deficit given other improvements).
  • New tests for all new features or code paths.
• If making a modification to third-party dependencies, yarn audit passes.
• A descriptive summary of the PR has been provided.
