Sablier EVM Utils

This repository contains the following two sets of contracts:

Sablier comptroller

Its a standalone contract with the following responsibilities:

• Handles state variables, setters and getters, and calculations using external oracles to manage fees across all the Sablier protocols.
• Authority over admin functions across Sablier protocols.

Utility contracts

Its a collection of smart contracts used across various Sablier Solidity projects. The motivation behind this is to reduce code duplication. The following projects imports these contracts:

• Sablier Airdrops
• Sablier Flow
• Sablier Lockup

In-depth documentation is available at docs.sablier.com.

    // Use the `noDelegateCall` modifier to prevent delegate calls.
