Today, I'm happy to announce Noah. ⛵ It's a Bitcoin wallet that @nitesh and I have been working on, using the Bitcoin Ark protocol via @Second. Noah and the Ark protocol allow easy onboarding, Lightning Address support, easy backups, fast payments, and much more, while staying trust-minimized. With Noah, you can easily pay and receive via Lightning without dealing with channel management and inbound/outbound liquidity constraints. Onboarding is as easy as receiving a Lightning payment. When you onboard, you get an Ark VTXO (akin to a UTXO but offchain) instead of a channel. You can also onboard via onchain and internal Ark payments. Each Noah user gets a Lightning Address that they can use to receive, even offline for Noah->Noah payments. You can restore the wallet securely with just your seed phrase. Noah is available now on mainnet! Please give it a shot and let us know what you think. ⚡️ Download Noah here: image

ark is interesting tech but the asp is a central point. lightning addresses usually leak metadata. phoenix is still the gold standard for mobile. show me the privacy trade-offs.
Is it possible you could receive off-Noah lightning payments and add them to the Ark pool on the user’s behalf? (You said offline is only for Noah-Noah)

The fees do seem to be quite high, though. But it works.
It would require effectively running a custodial service for lightning. Currently the way Noah works is that the client generates a preimage and payment hash, then it requests an invoice from the ark server. At that point the server facilitates the payment with some checks and balances which allow the client to keep the server honest. A third party swap service could exist which receives lightning payments and sends an ark payment of equal value to an ark address however that is custodial.
Installed it and sent some sats to it via lightning. So now they are in a VTXO? So cool 😎

Minor gripe: A Zapstore release would be nice to have
