Sablier Solidity Utils

This repository contains a collection of utility smart contracts used across various Solidity projects. The motivation behind this repository is to reduce code duplication.

The following projects use these contracts:

• Sablier Airdrops
• Sablier Flow
• Sablier Lockup

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

Install

Node.js

This is the recommended approach.

Install using your favorite package manager, e.g., with Bun:

bun add @sablier/solidity-utils

Then, if you are using Foundry, you need to add these to your remappings.txt file:

@sablier/solidity-utils/=node_modules/@sablier/solidity-utils/

Git Submodules

This installation method is not recommended, but it is available for those who prefer it.

First, install the submodule using Forge:

forge install --no-commit sablier-labs/solidity-utils

Second, if you are using Foundry, you need to add these to your remappings.txt file:

@sablier/solidity-utils/=lib/solidity-utils/

Usage

import { Adminable } from "@sablier/solidity-utils/src/Adminable.sol";
import { Batch } from "@sablier/solidity-utils/src/Batch.sol";
import { NoDelegateCall } from "@sablier/solidity-utils/src/NoDelegateCall.sol";
import { SablierFees } from "@sablier/solidity-utils/src/SablierFees.sol";

contract MyContract is Adminable, Batch, NoDelegateCall, SablierFees {
    constructor(address initialAdmin) SablierFees(initialAdmin) { }

    // Use the `noDelegateCall` modifier to prevent delegate calls.
    function foo() public noDelegateCall { }

    // Use the `onlyAdmin` modifier to restrict access to the admin.
    function editFee(uint256 newFee) public onlyAdmin { }
}
