Currently users have no option other than wrapping surplus ERC20 tokens to keep the streams running. These tokens do not earn interest since Superfluid protocol is relatively new and DeFi is yet to be introduced on streams.
Stroller Protocol allows users to earn yield on ERC20 tokens without the compulsion of having to wrap them to Super Tokens. This is enabled by creating Strollers which top-up the streams with just enough Super tokens to keep the streams running without any penalties.
Users can invest their tokens in other DeFi protocols like AAVE, Harvest, etc. and approve the receipt tokens for our contracts. For example, Alex invests USDT in AAVE and gets amUSDT in return. She approves amUSDT for our contracts and creates a stroller. Whenever her USDTx stream will have low balance to keep the stream running for a threshold, these amUSDT tokens will be converted to USDT and transferred to Alex as USDTx.
Using the Top-Up service provided by Stroller Protocol, users can now be tension free about their streams running dry. Approve, create a stroller and relax. The protocol handles the headaches for you.
The Stroller Protocol is built on SuperFluid, ChainLink and Moralis.
Users approve their invested tokens and create a stroller.
ChainLink Keepers keep checking for users' Super Token balances. If the balance can not keep the stream running for a certain threshold of time, the invested tokens are liquidated and wrapped to Super Tokens and sent to the user. This method is called Top Up.
📉 Low super-token balance => sell some investments => keep stream running 🤑
The events are indexed by moralis and displayed on the frontend. We use Moralis triggers to mutate data from the Event table to a Stroller table. We also use The Graph for querying all the stream related data.
