yeah, you onboard user funds offchain via a “virtual utxos” that are linked to the onchain utxo. You can do this in a trustless way. I don’t fully understand it yet because it almost sounds too good to be true, still looking through the code. I see musig and tweaking which is interesting… 

 Wow. Does any movement happen on-chain during the vtxo process? If not, what a scalable solution IMO.  Looking forward to more sharing on this from you.  🤯 

 onboarding is out of round, so its instant. You just provide a taproot address and the ASP virtually allocates a bit of the utxo to your address. If you want to do a unilateral withdrawal you need some btc in your wallet but otherwise it requires no inbound liquidity. 

 🐇🕳️ thank you! 

 say whattt?!?!?  So cool. Thanks for looking into this!
