The ideas exist. They're just scattered everywhere.
We collected them so you can stop searching and start building.

There's no good UX for giving an AI agent money, letting it transact on your behalf, and staying in control. OpenClaw, MoneyDevKit, and Alby are moving fast here but it's wide open. Some inspiration here, here, and here.
Not a crypto game. A classic game with a real bitcoin economy, played entirely by AI agents, watched by humans. Think board games with actual stakes.
Every new bitcoin app starts the same way: building a balance display, an address formatter, a block clock. From scratch. ShadCN solved this for web UI with a community directory. Nobody's done it for bitcoin.
Bitcoin Core proposed a showcase design for visualizing node activity. Nobody has built it as a real desktop app yet. The design exists. The implementation doesn't.
The topic is complex and most explanations are either too technical or too dismissive. There's room for something interactive, visual, and honest about the current status and ongoing work.
Nobody is collecting positive, real sentences from actual bitcoin users. Not influencers, not maxis. Just regular people saying what it did for them.
Nothing in bitcoin is built for how Gen Z uses the internet. The interfaces, the language, the onboarding. What if you had to earn their attention first? For inspiration, check this.
Most apps that could use bitcoin don't know it yet. What new product experiences can you build that use instant permissionless value transfer as an enabler, not the main feature?
Payjoin Dev Kit exists and Bull Bitcoin and Cake Wallet have shipped v2 integrations. But that's two wallets. The work is mostly language bindings: Java for Sparrow, Swift for FullyNoded, C++ for Bitcoin Core and Nunchuk, Python for Electrum, Dart for Aqua. Start with Payjoin Dev Kit.
Most bitcoin wallets give merchants a receive screen. That's not a POS. A POS has preset items, a keypad, notes, payment history, and a way to export it all. BTCPay Server has this but requires hosting your own server. Wallet of Satoshi and Breez have it as mobile apps, but neither tracks payment rails or exports clean accounting data.
Most holders have coins in multiple wallets with different cost bases and no idea what the tax hit looks like if they spend right now. CoinTracking and Koinly let you simulate a sale, but both are buried features in year-end tax software built for traders. Nobody's built the forward-looking version for everyday spending: connect your wallets, see your basis, know before you tap.
Clams is the closest thing: double-entry accounting with on-chain and Lightning support, fiat multi-currency, and cost basis tracking as of V1 Beta. But it's not fully open source and has no invoicing. BTCPay stops at the accounting boundary. Zaprite has the best invoicing UX but it's closed-source SaaS. GnuCash can't handle satoshi precision.
