World's first Bitcoin Covenants wallet. Powered by BCH

[Joemar Taganna @joemar_taganna]

Are you tired of crypto conferences where the conversation is no longer about building open financial systems, but about reshaping crypto until it behaves like the very system it was meant to challenge?

Too many events today revolve around regulated custodians, permissioned infrastructure, compliant stablecoins, institutional gatekeepers, and ways to fit crypto neatly back into traditional finance. The industry that once aimed to remove intermediaries is increasingly focused on rebuilding them with blockchain branding.

What if, instead, we talked about peer-to-peer cash, self-custody, censorship resistance, open networks, programmable money, and real-world economic freedom again — and more importantly, how to build products and businesses that create real value with these technologies?

Not just speculation. Not just financial engineering. But actual applications people can use: payments, marketplaces, remittances, digital commerce, AI agents, gaming, identity, coordination systems, and entirely new economic models that only become possible because crypto exists.

That’s the future we want to explore at the Cash 3.0 Conference. Join us!

Educating people on what Bitcoin covenants are, what they do and how they are a paradigm shift to crypto products and solutions. Amazed to see the rest of the industry still stuck on private key management. At least we have all these fun toys on $BCH

[VLAD HOSTS THE BEST PODCAST IN BITCOIN @Vladcostea]

Tomorrow I’m interviewing a dozen BCH guys in my podcast

Not only because it’s been almost 9 years since the split

But also because BCH has been doing a pretty good job with adding OP codes for devs

And it was 2 years ago that I got excommunicated from the Church of Bitcoin for interviewing Roger Ver

Fun times!

Massive shout-out to @dagur and the @RiftenLabs team for the exponential growth in users and activities in the past 2 years at @bchbliss

[BCH-1 @bch_1_official]

Congratulations to the Bitcoin Cash ecosystem on the successful Layla upgrade activation.

This is one of the most important upgrades $BCH has seen in years.

Bounded loops, restored bitwise operations, reusable functions, expanded CashVM capabilities, and deeper programmability are now live on Bitcoin Cash.

We are beginning to see the early stages of what will become a major expansion in BCH use-cases.

DeFi on Bitcoin Cash is coming at a level many people still underestimate.

Dapps and developer platforms are all beginning to form simultaneously around CashTokens and CashScript.

Just as important, the ecosystem around BCH is evolving beyond pure protocol development.

Marketing , capital pipelines , creator economies, entrepenuers solving problems, are beginning to kickstart alongside the technology itself.

The chain is becoming easier to build on, easier to coordinate around, and easier to deploy real products into.

As proud sponsors of BLISS, BCH-1 is on the ground showcasing the continued growth of the Hackcelerator and the teams building through this next phase.

Post-Layla, $BCH enters a new era.

Bitcoin Cash continues strengthening its fundamentals regardless of market conditions, expanding its capabilities while staying aligned with Bitcoin’s original peer-to-peer design.

[Sylvain @sylcloutier]

Great to see $BCH having their own event! A change from BTC digital gold meetup! 😉
I have not been able to watch the stream yet, but I will try to catch a bit of it!

Decentralization, P2p transactions, privacy & scalability! ✅

🚀 Big news: starting with version v0.24.5, Paytaca is finally live again on Google Chrome as a Browser Extension.

After nearly a year of being stuck on an outdated wallet version due to Chrome Web Store-related limitations, the extension is now back on track and fully updated with the latest improvements from the Paytaca ecosystem.

This means Chrome users can once again access modern Paytaca features directly from their browser — with a more polished experience, improved performance, newer BCH and CashTokens capabilities, and ongoing feature parity with the mobile app.

The return of the Chrome extension is an important step toward a more seamless multi-platform Bitcoin Cash experience for users, merchants, developers, and the growing CashTokens ecosystem.

⚡️ Update now to v0.24.5 and experience the latest generation of Paytaca on Chrome.

"When users can actually see what they're working with, it becomes a lot less abstract. You stop having to talk about the blockchain."

Meet Jerry Qian (@Lightswarm), founder of @OPTNLabs. He's building a Swiss Army knife for on-chain control: customizable contracts, post-quantum vaults, and real key ownership, all on Bitcoin Cash.

Part of our Founder-First Showcase 🇨🇦

[Blockchain North @BlockchaiNorth]

Most Canadian startups do not fail at product. They fail at visibility.

The Founder-First Showcase spotlights Canadian startups & scaleups with content and reach.

Spring cohort:
- Sheereen Khan, @Regulativity Inc. Transforming regulatory requirements into scalable, auditable workflows.
- @Lightswarm, @OPTNLabs. Building blockchain infrastructure and programmable money on $BCH.
- @athikafz, @oneheart_p. A decentralized donor incentive protocol for blood donation on Starknet.
- @sam_drissi, Human IP. AI-driven patent intelligence and tokenized patents as a new asset class.

Canada is building. Let's pay attention.

I'm organizing another BCH Toronto meetup Tuesday Apr 21 @thefirkinbar on Yonge. Come check out the post quantum vault currently available only on Bitcoin Cash. I have a couple of paper wallets as well for newcomers. RSVP below

Update the OPTN wallet and try out sweeping paper wallets and more. We love to hear from you on what features / UX designs you like to see

https://t.co/gihitFOZgQ

[OPTN Labs @OPTNLabs]

You asked, we listened. Paper Wallet sweeping has been ported from the custom transaction builder to its own dedicated add-on in the OPTN wallet ecosystem. We support bulk sweeping of $BCH, cashtokens and NFTs all at once.

Shoutout to @stevethurmond for @cashstamps paper wallets
