As you evaluate bitcoin security solutions, be wary of MPC custodians selling their solution as equivalent to multisig. MPC is not native to bitcoin, and is often implemented at an operational abstraction on top of a single signature. IE: funds are secured by a single private key, but that private key is essentially sharded in a way that requires multiple people/signatures to create the bitcoin private key signature to move funds. It SOUNDS like multisig but it’s not. If there were an entropy mistake like Coldcard’s in how that single seed was created, MPC is not helping.
There are perfectly reasonable ways a custodian would use MPC with multisig, but it is not a replacement. The goal is to eliminate single points of failure.

Bitcoin. Previous builder of Unchained Capital and Stack Overflow. Now building Zaprite.
If you’re still in single sig world, Cold Card or otherwise, please consider the upgrade to multisig. I worked on and recommend Unchained. Bitkey and Casa are also great options. Multisig with multiple hardware vendors is phenomenal security and easy to set up. These companies will hold your hand to make it easy for you.
If you don’t want a corporate coordinator, BTC sessions has done excellent guides on Multisig setups with sparrow. Go to his YouTube channel.
If you need time to consider all this and are on an affected cold card device, consider River and Stike as temporary custodial options.
You’re not stupid for using single sig. You’d be shocked by the number OG’s affected by this. Every few years we get a reminder to harden our security posture. So take a deep breath and do the work!
These guys are nuts.
Bitcoin is the great definacialization. Good time to re-read!

But it’s so hard to pay with bitcoin…


It’s hard to truly decentralize anything other than money.
Zaprite gets paid to be featured at Ferrari week at COTA in Austin.


March 13 1836 was a grim day during the Texas revolution. Sam Houston and his army learned of the fall of the Alamo and decide to retreat east. Rock bottom morale…
But in 2026 Parker Lewis, backed by the glory of of the Lone Star flag, talks about Zaprite and the P2P app we are building to facilitate payments worldwide.


Point your favorite AI model at https://api.zaprite.com/llms.txt if you're looking to integrate bitcoin payments into your app. Less searching and fiddling. Stack more sats.
March 2, 2026 - The 190th anniversary of Texas Declaration of Independence from Mexico. In 1836, The Alamo is still under siege while delegates from Texas meet at Washington on the Brazos (between modern day Houston and College Station) and unanimously approve the declaration. Bad news is coming in a few days from the Alamo, but the Texians have cemented themselves as sovereigns instead of rebels. That will be an important distinction in our dealings with America and others soon.
Between those at the Alamo and Refugio on this day, and the signatories below, you have a good chunk of all the town and county names in modern day Texas.


Sitting outside on a beautiful Feb 25th day in Austin, Tx and it hit me…I remembered the Alamo.
It’s actually day two of the siege at this point. Alamo defenders haven’t yet got word out on just how bad their situation is. But Crockett, Travis, and a sick Bowie are holding down the fort.
Goliad isn’t much better. Fannin has disobeyed direct orders to retreat and regroup and dug in for defense. Urrea is leading a massive force up the coast to meet them.


It’s time to invade New Mexico and reclaim our Texian birthright of Taos and Santa Fe.


I turn my back for 6 months and Alby hub becomes unbelievably cool. The isolated app connection workflow is incredible.
Gratifying to see so many stack sats at the local bottom getting their @Zaprite invoices paid at the beginning of the month, or sell tickets to their events. Congrats humble sat stackers.
Some of you thought it was OK to own chairs, and it shows.
Max pain is sub 50k
It’s been this way for a couple of months. X is completely useless. One of the best products ever built. Before it was censorship of right wing voices that threatened it. Musk really did save it. But now the censorship is way worse - anything that is not about Minneapolis is buried. The network effect has been gutted. The worst product team fuckup I’ve seen in a long time.
The storm was not fake news. None of this is snow. All ice in Texas.


2026 is going to be huge for Zaprite. Our Event and Tickets product came out of the womb with a full head of hair and teeth, but we’re adding native ticket transfers, and easier ticket issuance for event organizers. The API gets better every week, integrations with excellent Bitcoin wallets continues to expand (also fiat integrations like quickbooks just launched) and the invoicing product is being adopted by companies that don’t even prioritize bitcoin payments.
However, I’m most excited for expanding bitcoin’s peer-to-peer native abilities in 2026.
I seriously love what I get to do.
There is endless silver in Mexico.
