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

The following projects imports this repo:

• Sablier Airdrops
• Sablier Flow
• Sablier Lockup

In-depth documentation is available atdocs.sablier.com.

This repo contains the following subdirectories:

• src/interfaces: Interfaces forAdminable andBatch contracts.
• src/mocks: Mock contracts used by external projects in tests.
• src/tests: Helper contracts used by external projects in tests and deployment scripts.

This is the recommended approach.

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

bun add @sablier/evm-utils

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

@sablier/evm-utils/=node_modules/@sablier/evm-utils/

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/evm-utils

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

@sablier/evm-utils/=lib/evm-utils/

import { Adminable }from"@sablier/evm-utils/src/Adminable.sol";import { Batch }from"@sablier/evm-utils/src/Batch.sol";import { NoDelegateCall }from"@sablier/evm-utils/src/NoDelegateCall.sol";contractMyContractisAdminable,Batch,NoDelegateCall {constructor(addressinitialAdmin)Adminable(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(uint256newFee)public onlyAdmin { }}
