Radar integrates self-custodial Bitcoin payments directly into Signal's messaging network, eliminating the need for separate apps or custodians when sending value to contacts.

Seth for Privacy, from the Cake Wallet team, explains how Radar targets everyday users rather than Bitcoin maximalists by preserving Signal's privacy model while adding instant Lightning-enabled transfers via Spark.

The discussion covers seamless account migration from Signal, offline payment receives, wallet risk limits for non-critical funds, and the decision to pursue VC funding through a separate entity.

Payjoin delivers transaction batching driven by real economic activity rather than waiting for pool participants, while also cutting fees through direct net settlement between counterparties.

Dan Gould, maintainer of Payjoin DevKit, explains how the new async protocol and oblivious HTTP relay change what is practical for mobile wallets today.

The conversation covers current live deployments in Bull Bitcoin and Cake Wallet, remaining fingerprinting heuristics beyond common input ownership, the multi-party roadmap, and how developers can integrate the library with under ten thousand lines of code.

A South African circular economy is already running real payments on Fedimint with seven guardians on Start9 boxes. Users send eCash with zero fees inside the federation and feel the same simplicity as Wallet of Satoshi—except the custody is local and the privacy model is different.

Hermann and Joshi explain how non-technical guardians set up 5-of-7 multisig, how the Conduit wallet hides complexity, and why Fedimint beats Liquid on on-chain integration and local trust. They also cover Lightning gateway economics and why small federations may beat one global Spark.

Bitcoiners exploring Lightning, eCash privacy, and circular economies in emerging markets should listen.

Key Takeaways:

1. Seven-guardian 5-of-7 multisig on Start9 now runs daily in South Africa with high reliability.

2. Users inside the same federation enjoy true zero-fee eCash transfers.

3. Conduit wallet offers a lighter, payments-focused alternative to Fedi with regional QR support.

4. Migration between federations is smooth with parallel running and user-controlled timing.

5. Fedimint severs the transaction graph for privacy while Liquid hides amounts but retains the graph.

6. Local guardians reduce the “custodial guilt” felt when onboarding users to foreign services.

7. Lightning gateways can become profitable side businesses with only a few hours of monthly work.

8. Geographic spread of guardians improves resilience against local internet or power outages.

9. Onboarding still requires one extra step—joining the federation—after app install.

10. Fedimint is on-chain native, allowing direct receive and send without intermediate swaps.

In this urgent 15-minute conversation, Stephan speaks with Ricki Allardice, one of the leaders of the Property Rights Defense Group, about South Africa’s Draft Capital Flow Management Regulations 2026 — the most serious threat to Bitcoin self-custody the country has seen.

Ricki breaks down exactly what the draft rules would do to private keys, self-custody, and everyday Bitcoiners, where the process stands right now, and what the community can still do before the 30 June 2026 public comment deadline.

Matt McClintock (Founder & CEO of Bespoke Group) returns to the show alongside Alla Futterman (Associate Client Relationship Manager & Head of Philanthropy Operations) fresh off his main-stage talk at BTC Prague 2026 titled “Using Bitcoin to Change the World.”

In this deep dive, we explore how ultra-high-net-worth Bitcoiners and their families are moving beyond simple HODLing to become active stewards — deploying Bitcoin through sophisticated, values-aligned philanthropy to solve real problems (landmine clearance, human trafficking recovery, wildlife protection, cultural preservation, and more).

We unpack Bespoke Group’s “Wealth Operating System,” sovereign estate planning for bearer assets, tax-efficient giving structures, next-gen involvement, the mindset shift from ownership to “this wealth has been entrusted to me,” and practical advice for Bitcoiners at every level who want their capital to outlive them and actually improve the world.

If you’ve ever wondered how to turn Bitcoin conviction into lasting generational impact while keeping sovereignty and privacy intact, this is the episode.

In this episode, we sit down with Adam Juchniewicz of Bitcoin Passport Index and Bitcitizen to discuss Bitcoin sovereignty, jurisdictional arbitrage, and how Bitcoiners should think about second passports and residencies.

We dive into the Bitcoin Passport Index, why Bitcoin-friendly tax and legal treatment matters more than most people realize, and how the landscape for citizenship and residency programs is rapidly changing.

Adam also breaks down his fast-track Vanuatu citizenship program and his full-service approach to helping Bitcoiners build a proper sovereign stack — from companies to passports to, in some cases, full exits.
