Swapping across Bitcoin, Lightning and Liquid with Kilian from Boltz.exchange SLP557

How do we interact with Bitcoin in a multi layer world? What cost savings and trade offs are necessary here? What even counts as a layer? Kilian from boltz.exchange joins me to talk about swapping across Bitcoin on-chain, Lightning and Liquid. We discuss:

• How swapping works
• What makes it atomic and non-custodial
• What counts as layer 2
• Fee savings and trade offs
