Been trying out what might be among the world's first ARK transactions on Bitcoin mainnet. Here I send some sats from the @ArkLabs wallet to my Phoenix wallet (using a LN swap). Bullish!

ARK is a new type of Layer 2 protocol with the UX of E-Cash but non-custodial. When it was announced first in 2023 it was clear that it would require a soft fork like CTV to even work though. Now 2 years later it's here live on Bitcoin mainnet, without the need for a new soft fork at all. And with the interoperability with Lightning it will create some interesting wallets and new use cases.

How do I get the ark wallet?
We tested zaps and zap receipts on this note… we made six attempts to⚡zap this note, at ln@swapmarket.online, over a period of about 4 hours. Six of the zaps were successfully paid... Please check for 6 satoshis received. Problem: we found that your lightning address server **did not* properly produce zap receipts, and/or didn't send the zap receipts to the relays specified in the zap. This means that nobody else could see see that you got zapped... no number appears next to the ⚡icon after zapping.... You might want to look into using a cloud-based Lightning node to get more reliable zaps.
Do you know how it works out with the capital efficiency and the fees? Iirc the sequencer needs to put up all liquidity for the Volumen during the lock time period (capital efficiency) and it needs to make an onchain tx every round (fees). Maybe they solved this along the way.

That will be a challenge: since VTXOs are UTXOs, they are bound by the dust limit. In other words, you will not be able to unilaterally exit a VTXO with value less than the dust limit, so it would not be trustless. Of course you could receive several low value VTXOs and trust the server it will allow you to swap all of them later for a bigger VTXO. It's not 100% trustless, but you only need to trust the server for very low amounts. It could work.
This is how most LN setups and e-cash work. For small amounts it’s not any different than current solutions.
