Abstract

There is an increasing need for off-chain infrastructure in the Supefluid ecosystem as more projects, protocols, and individuals need to interact with contracts in complex, scheduled, or automated ways. This includes, but is not limited to, insolvent stream liquidation, pre-insolvency courtesy stream closures, scheduled transactions, and meta transactions.
