About

A super simple foundry/Hardhat hybrid project which utilizes Superfluid's CFA Access Control List feature and Gelato to close a flow at a predetermined time in the future.

Built With

• @superfluid-finance/ethereum-contracts
• @superfluid-finance/sdk-core
• foundry
• Hardhat
• Gelato Ops

Prerequisites

In order to run this project, you need to have the following dependencies installed on your computer:

• foundry
• yarn or you can just use npm, but you'll need to change up the Makefile slightly.

Project Setup

To set up the project run the following command:

yarn // installing the node_modules

yarn compile // compiling with hardhat the project

Deployment, creating the stream, authorizing, creating the task and mock the execution

Local on a forked network

Copy the .env.template--> and enter your private jey, infura Id and Etherscan if required We will open a second terminal and run:

yarn fork // fork the network into a local hardhat node

Contract deploy:

yarn deploy localhost

The console will log something like:

Close Sream deployed succsessfully at:  0xCC7FA88DB7df720EA72872ad7C19fd85026047d9

We will copy the deployed address into the './scripts/Helpers.ts' so it will be available later.

export const CloseStreamAddress = "0xCC7FA88DB7df720EA72872ad7C19fd85026047d9";

We will now start a stream

yarn startStream localhost    // in scripts/startStream.ts 

Authorize our smart contract to stop the stream

yarn authorizeControl  localhost   // in scripts/authorizeControl.ts 

Create the task

yarn createTaskStopStream  localhost   // in scripts/createTaskStopStream.ts 

We are goig to mock the Gelato execution, so we will need exactly the start time of the task, when deplpoying on goerli we wont require it as the executiojn will be done by the Gelato executors

  console.log:
    1666974177

We copy the timestamp '1666974177' into the stopStreamscript and we mock the gelato execution:

yarn stopStream localhost

Goerli

Contract deploy:

yarn deploy goerli

The console will log something like:

Close Sream deployed succsessfully at:  0xCC7FA88DB7df720EA72872ad7C19fd85026047d9

We will verify our contract to interact later with etherscan

yarn verify goerli  // in scripts/verify.ts 

We will copy the deployed address into the './scripts/Helpers.ts' so it will be available later.

export const CloseStreamAddress = "0xCC7FA88DB7df720EA72872ad7C19fd85026047d9";

We will now start a stream

yarn startStream goerli  // in scripts/startStream.ts 

Authorize our smart contract to stop the stream

yarn authorizeControl  goerli  // in scripts/authorizeControl.ts 

Create the task

yarn createTaskStopStream  goerli   // in scripts/createTaskStopStream.ts 

Our contract is verified here Gelato task logs can be found here
