Most people hear “crypto products” and think: DEX #57, new L2, another AI token.
Meanwhile, the really interesting stuff quietly solves boring, real-life problems.
1. Crypto Cards: Adoption in Disguise 💳
Crypto cards are basically skins for rails.
You tap in a café, and under the hood:
- crypto gets converted
- FX happens
- risk rules fire
- payments settle on TradFi rails
Nothing glamorous - but this is where “number go up” turns into “I paid rent with it.” As devs, we should care a lot more about the infra behind that tap than about the logo on the plastic.
2. On/Off Ramps: The Real Boss Level 🔁
On/off ramps are the border control between bank balances and tokens.
Good ramps make “deposit via SEPA / card / local method” feel boringly simple.
Bad ramps turn every top-up into KYC roulette and failed payments.
Architecturally, it’s PSPs, compliance, risk engines, and reconciliation hell.
But if you ever shipped a product where users need to fund accounts - this is the layer that decides your conversion rate.
3. WB Checks: Sending Crypto Like a Link 🔗
One under-the-radar idea I like: WB Checks.
You generate a check, share it as a link or QR, and the recipient just pastes their wallet address to claim the funds. No account needed, no scary forms, no “what network do I pick?” anxiety - just “here’s your value, grab it.”
It’s a tiny UX trick that quietly removes half the excuses people have for not using crypto.
If you haven’t heard of WB Checks before, I’d honestly recommend reading the article - good inspiration for anyone designing low-friction flows in Web3 🚀
