Magik said a payment channel (with hashlock) can be stacked with a multisig (which has timelock) to enable atomic swaps with other chains.
What cross chain integrations are possible and desirable until user-defined smart contracts are available in Filecoin?
Use cases:
  • Basic token swaps (easy)
  • Enabling smart contracts to have Filecoin store stuff (hard):
e.g. along with the CID Oracle idea, could a service provider offer to store on your behalf if you pay with their wFIL?
Other possibilities?
