Juicebox Sips: Juicebox + Sablier v2 Token Streams

Summary

A Juicebox treasury extension which, when added to a projects funding cycle payout splits, receives ETH and optionally swaps into a target token defined by deployer. Sablier v2 Token streams can be created, cancelled, and otherwise managed by the respective Juicebox Project operators via JBSips.

Use-case & background

Mitigate the trust issues of onboarding new contributors by paying via cancellable Sablier V2 Token Streams.

Also we kinda built this to jam with cool people at Sablier: Juicebox Proposal #412

Design

Create Flow

• Deploy JBSips and attach it to a projects funding cycle splits
• Payout your Juicebox Project which sends ETH -> JBSips.allocate()
• Project operator calls JBSips.deployStreams() with their Sablier stream configs
• A PRB Proxy and Plugin are deployed which allows the JBSips contract to act as a stream management hub
• Streams are then deployed and stored by funding cycle in state variable JBSips.streamsByCycleAndAddress

Cancel Flow

• Project operator calls JBSips.batchCancelStreams()
• Funds are returned to JBSips
• User can withdraw amounts streamed before cancellation

Token Dusts

• Project operators can use JBSips.withdrawETH(), JBSips.withdrawTokenDust(), JBSips.withdrawAllTokenDust() to withdraw any leftover balances.

Access Control

• Project Operators with JBOperatable permissions in this case "SET_SPLITS"
