BRH-003: BitDevs Radio Hour #3 – Zeus Wallet, Graduated Wallets, eCash, and the Future of Bitcoin UX
Description
Live from ATL BitLab, Stephen DeLorme and Alex Lewin sit down with Evan Kaloudis, founder of Zeus, one of Bitcoin's most beloved Lightning wallets.
This episode dives deep into the design trade-offs of non-custodial Lightning, the emergence of "graduated wallets," eCash systems like Cashu and Fedimint, statechain-based systems like Spark, and the future of Bitcoin payments UX.
The conversation ranges from practical LSP economics to the viability of Ark, Spark, and other L2 proposals, as well as Evan's views on privacy, trust models, griefing attacks, covenants, and how wallets should guide users up the self-custody ladder.
Plus: merchant adoption, credit-card fee wars, and a closing reflection on how AI is reshaping modern engineering and Bitcoin development.
Guest
Evan Kaloudis – Founder of Zeus, the mobile Lightning wallet that began as a remote node controller in 2019 and has since evolved into a full Lightning stack with embedded LND, LSP functionality, swaps, eCash capabilities, and B2B onboarding tools.
