Omnichain

What everyone needs to know​

  • A sucker is the component projects use to connect multiple instances of Juiceboxes across chains.
  • A sucker is kind of like a bridge, with some special properties that make omnichain Juiceboxes work well together.

See Omnichain for more.

What you'll want to know if you're building​

  • We call the component that bridges project tokens alongside their juicebox balance a Sucker.
  • Each chain has a JBSuckerRegistry that stores info about how local projects are connected to projects on other chains, through calls like JBSuckerRegistry.suckerPairsOf(...). This is also the contract where new suckers should be deployed from.
  • There currently are IJBSucker implementations for native bridges between Ethereum mainnet and Optimism, Arbitrum, and Base, as well as a CCIP version for bridging between the L2s and any number of other EVMs into the future.
