Stack Wallet has released a new update (1.7.0, build 160) for both Android and iOS.
This is a big update. The biggest of which is Stack Wallet now supports the sending and receiving of Ethereum and ERC-20 tokens. There is NOT any web3 functionality. Just sending and receiving.
In addition, we've taken this opportunity to update our UI in several areas where it was lacking. The add wallet flow, for example, has been updated to accommodate for adding ETH and tokens and generally easier to navigate.
This release also includes other smaller bugfixes like for Firo sending edgecases and more.
In regards to ETH, there may be bugs. Nothing that should make a user lose funds, but it's a big big addition with a lot of code changes. Use caution, remember Stack Wallet is in open beta status, and let us know how we can improve things.
Note that this does NOT affect Stack Duo, which remains Bitcoin and Monero only. :) And we'll have some goodies coming from Bitcoiners very soon, don't you all worry. You haven't been forgotten.

Here at Stack, we take design very seriously, and most screens go through several iterations to get it right. Our UI/UX team is top notch, and among the best in the space, and the end result shows it.
Note, these are just the completed screens. We have many many more files of different themes, features, and more.

Stack Wallet has released an update v1.6.9, build 152.
Release notes:
- xpub can be viewed for all Bitcoin derivative coins.
- Orange theme released (paid for by @SovrnBitcoiner)
- Epic Cash min confirmations reduced to 3 from 10
- Updated Wownero to the latest fork (doesn't sync yet)
- Fixed Epic Cash Send All not calculating correctly.
Lightning not in Stack yet. I'd like to be receiving zaps there if you know what I mean. Can enable them when that's live. ;)
Yes it is. Toggle on testnet coins in the Advanced settings. Then tap the Add New wallet button and select twitching and you're ready to go.
So uh...Stack Wallet on Nostr?
