Note for users of the new Primal wallet: The new wallet denoted as "self-custodial" by Primal uses Spark. Spark is an API provided by the Los Angeles company LightSpark. (

) LightSpark is a competitor to Megalith & Rizful, so we're generally committed to keeping our mouth shut with regard to LightSpark's overall merits. But: everyone should know that LightSpark payments over the Lightning network can have significant LATENCY...... LightSpark is doing quite a lot of complicated stuff "on top" of the Lightning network. If, for example, you were using the previous Primal wallet (provided by Strike), you might have been able to zap a user and get a confirmation of successful zap within 1 to 2 seconds. Using LightSpark's API, by contrast, our tests indicate that a zap confirmation can take upwards of 10 seconds. (TEN SECONDS!) We're bringing this up because we're seeing a lot of "I can't zap" complaints recently. If you're having problems, check your lightning address service -- if it's run by LightSpark -- in this includes many wallets marketed as "self-custodial", such as Breez, Wallet Of Satoshi, Primal, and others.... it might be that you CAN zap and zaps DO work, but that you're just not used to waiting 10 seconds for a confirmation, so you're giving up and closing out of the zap attempt early....

A representative from Rizful & Megalithic.me will be at the the BTC conference in Vegas this week, possibly only for Tuesday. DM on Signal or Telegram if you want to meet up:

If you, or a developer you are working with, plans to run very high-volume requests against Rizful NWC, that's cool, but please contact us to let us know what you're doing so our system can whitelist your activity.

Rizful has made some upgrades to our NWC relay. You shouldn't notice any difference, but if you do or find you aren't connected, please restart your Nostr app.

New pitch for merchants: "You need to start accepting BTC for your coffee shop because down the road you might need to pay to get your tanker through the straights of Hormuz"

We are working on a long-term project which is quite complicated to explain but part of it involves onboarding confused "normies" with very limited brain-based context windows (maybe max 100 to 200 characters/tokens of possible input, maybe a 10 or 15 second attention span, at most)..... onto Bitcoin. These "normies", when they arrive at our door, think that "crypto is a scam" and have likely never been presented with the idea that Bitcoin and Crypto are different. We need a VISUAL way to make the case to them. We need I think ONE portrait-formatted image, ideally with no complete sentences. Here is our first attempt If anyone else finds a good portrait-formatted alternative to this (or makes one), please let us know!
