Neil, I am so appreciative that you approach things that way. This week I realized that Bark supports BOLT-12 offers and Lightning Addresses out of the box and was super impressed. I had avoided looking into those so far because I assumed it would be a massive headache to support. Huge win there.

So here’s the latest update, which is all about sending:

I expected it to be a big task to create really rich send experience, and it really is a lot with all the different payment formats we have, as well as handling multiple layers.

Goal here was to create a super simple send experience, no matter what payment information is thrown at the Send view:

Entry points

- Contact
- Clipboard, scan or URI click
- Manual entry

Address formats:

- Ark
- BOLT-11 Lightning invoice
- BOLT-12 Lightning offer
- Bitcoin
- Lightning address

Address pointers to resolve

- BIP-(3)21 URI
- BIP-353 human-readable address (points to a BIP-21)

Other logic

- Detect known addresses
- Check for network (mis)match (mainnet, testnet, signet, regtest)
- Per address, validate sufficient balance and estimate fee
- Transaction notes & tagging

It will probably take another week to really refine and polish this.

Do you think what’s in the video is a good direction? What’s good/bad/missing? Is it overkill? Let me know.

Lots of my thinking is based on content from the Bitcoin Design Guide, like the  
[Sending](https://bitcoin.design/guide/daily-spending-wallet/sending/), [Payment request formats](https://bitcoin.design/guide/how-it-works/payment-request-formats/), and [Human readable address](https://bitcoin.design/guide/how-it-works/human-readable-addresses/) pages. Plan is to refine some of the content based on my learnings from Arké.
