Superfluid is a smart contract framework that adds new ways to move digital value to the traditional ERC20 token standard we know and love.

Superfluid consists of 4 main components: Super Tokens, Super Agreements, Super Apps, and the Superfluid Host. Read this overview to understand the "what" and the "how" behind these components and how they interrelate.

What can you build with Superfluid?

Here are a few examples of what you can build for this hackathon:

Celo Money Streaming Mobile Applications 📱

Celo is a mobile-first and EVM-compatible blockchain ecosystem. It would be really cool to see the use of Superfluid Protocol on Celo Mainnet in a mobile application - we have yet to see a good implementation of money streaming on a mobile interface.

Fixed-Interest NFT Lending 🏦

We would like to see this idea implemented in a very simple fashion

Create a smart contract that lets you put down an NFT as collateral and borrow stablecoins against it.

The borrow function pulls a stream from you using ACL to pay interest on your loan. So if you took out a 100 DAI loan and the APR is 10%, then a stream of 10 DAI/year would be started from your account to the NFT Lending contract.

Say you repay half of your loan (so now just 50 DAI outstanding), then the repayment transaction would update your stream down to 5 DAI/year. And if you fully repay, your payment stream would be cancelled.

If you cancel your stream to the NFT Lending contract, then no mercy! You’re liquidated.

API Subscription Market Place 🧑‍💻

Allow API offerers to sell access to their APIs via streams on Celo in a marketplace. This could make use of Superfluid Subscriptions for a better UX.

Stream Public Goods/Grants Funding🗳️

This project would revolve around creating a platform where individuals/initiatives looking for funding could create a profile. Donors could scroll through profiles and provide recurring funding through a Superfluid stream on Celo. This could make use of Superfluid Subscriptions for a better UX.

You could make the experience more involved by creating a stream donation management Super App smart contract that reacts to when someone starts a donation stream by minting them a nice NFT for their benevolence 🤗

Make a Stream-Gated Telegram Channel💬

With this project, you’d be able to only get access to a channel if you are streaming to a certain address. A hack to accomplish this is to make a “token” contract whose balanceOf function is overriden to return 1 if you’re streaming to the address or a 0 if you’re not. Then you could use basic tools like Unlock Protocol or Guild.xyz to do token-based gating.

This could make use of Superfluid Subscriptions for a better UX.

The inspiration for this concept comes from @rashtrakoff’s stream-gated Paragraph.xyz publications (see here and here)

Stream UBI 🤝

Use Celo, Superfluid, and GoodDollar to stream UBI (Universal Basic Income) following a particular set of rules, requirements, or behaviors.

Stable Asset Applications 💸

Use Celo's native stable assets: cUSD, cEUR, and cReal, to stream stable assets for particular use cases, such as payroll applications, tipping, and DeFi in general.

Tokenized Carbon Applications 🌱

Create climate-positive applications using Toucan Protocol's infrastructure on Celo and Superfluid.
