Bitboard Wallet is a learning web app for letting people explore Bitcoin layers 1 and 2 safely. Version 0.3.6 is out now. It adds Bark support, which I started implementing at the Bitcoin++ Payments Edition hackathon in Berlin. Improving UI, and handling important edge cases took some additional time. Bitboard Wallet is now one of the few wallets that both support Arkade and Bark, the first and second Ark implementations. Visual unilateral exits are implemented for both. Check it out on

I just completed the first emergency exit on #Bark with the current development version of Bitboard Wallet. Encountered zero issues along the way. I found it important to do that test before pushing out v0.3.6 with Bark support. Check out the app on

During the Bitcoin++ hackathon in Berlin I added Bark support for Bitboard Wallet. Adding a payment rail in a day is possible, but creating a new release with that new feature takes much longer. I need to make sure it plays along nicely with any existing functionality like: * Paying with Bitcoin on-chain, Lightning, or Arkade * Switching wallets or networks * Locking and unlocking the wallet Also, there's the issue about making all Bark features work reliably. For example, testing emergency exits (as visible in the screenshot) on Signet takes some time (10 Minutes for each single step). #bitcoin #layer2 #Bark #Bitboard #exits #hackathon

Let's create a decicated Unilateral Exit service for Bark and Arkade.

Bitboard Wallet is a learning web app for letting people explore Bitcoin layers 1 and 2 safely. Version 0.3.5 is out now. This is mostly a performance upgrade that fixes long sync waiting times by increasing the use of caching. That doesn't sound particularly exciting, but it makes wallets with a long transaction history feel snappy again. #Ark #Arkade #Bitboard #Bitcoin #dev Check it out on

Bitboard Wallet version 0.3.4 is out now. It mostly focuses on Arkade with better handling of intents and unilateral exits. Those unilateral exits are really tricky - trickier than most people realize. My idea was to make it more transparent what's actually happening by displaying it in a graph. The complexity of the underlying machinery is so high that this might be a dedicated app in its own right. But it's now easier for users to get them right: 1. Start unilateral exit in wallet management 2. Tap on one of the leaves in the graph 3. Tap on the "select this leaf for exit" switch 4. Optionally activate the "proceed automatically" switch (recommended) 5. Start the process - it runs in the background as long as the wallet is unlocked, if you did the previous step 6. Once the process has finished, you tap on "Complete unilateral exit" in wallet management 7. Select the coins you want to move to L1 and continue -> Exit complete That's still a significant number of steps, but it's a complicated process that is inherently error prone. Handling those potential errors gracefully was actually the biggest challenge of this new feature. I still suggest not trying this on mainnet, since the tx fees will burn your balance. Try signet/mutinynet instead.

Bitboard Wallet version 0.3.2 and 0.3.3 were bug fix releases mostly focused on Arkade: * Sync can now be manually triggered for each rail (onchain, Lightning, Arkade) * Added periodic sync option with customizable period per rail * Arkade signer key rotation should be handled gracefully now * Arkade now also shows fiat amounts when in fiat mode * Improved unilateral exit flow for Arkade by splitting it into a start and complete phase * Cross-tab write lock should make multitasking with multiple browser tabs safe It's still important to know that Arkade support is still new and rather experimental - but it's getting better. #Ark #Arkade #Bitboard #Bitcoin #dev

#Bitboard Wallet 0.3.1 was just released. Now the wallet supports Lightning pay via LNURL. Critically, the connection to the Arkade server was fixed. There were also some minor UI and security improvements. See

#Bitboard Wallet 0.3 now can do #Ark via Arkade. Wanted to include that until this year's #BTC Prague. This addition makes Bitboard much more useful than before. It's a layer 2 solution that's relatively easy to use. Check it out on

#Bitboard Wallet v 0.2.0 is available. Now you can unlock the new feature "UTXO selection" to pick the coins you want to use for a #Bitcoin transaction. Also, the UI now shows your balance and txs immediately instead of waiting for Esplora sync.

Version 0.1.7 of #Bitboard Wallet now supports conversion to more fiat currencies - depending on the rate service you select under settings. This is only informative. Bitcoins are not automagically traded into stablecoins or something. #bitcoin See
