Show HN: Hyprsqrl – open-source revolut you can self-host (live iban/sepa/ACH)

https://github.com/different-ai/hyprsqrl
9•ben_talent•8mo ago
Hi HN! Ben here from hyprsqrl, and I just open-sourced something we’ve been quietly running in production:

*hyprsqrl is a self-hostable bank.

Think Revolut (if you know it), but every line of code is MIT/AGPL, you can run it on your own box, and the crypto bits stay hidden under the hood.

---

### Why we built it Moving money between USD and EUR still means wire fees, surprise freezes, and “call your bank” hoops. Fintechs like Revolut help—until their pricing changes or a regulator knocks.

hyprsqrl aims for the resilience of self-hosting *without* forcing users to study crypto. Two recent shifts made that finally doable:

* *wallet abstraction UX is catching up*—passkey login support is coming next week (good-bye seed phrases) * *one-API on/off ramps* (AlignLabs today) let us bridge SEPA ↔ stablecoin and ACH ↔ stablecoin cheaply

Right now we lean on Privy for auth + wallet orchestration, but the plan is to drop it as soon as passkeys land and minimize third-party dependencies across the board.

---

### What’s live today * IBAN & SEPA inbound → auto-minted USDC/EURC on-chain * ACH payouts (live AlignLabs environment) * Next.js dashboard for balances, transfers, audit log * In production moving real money since May 2025

---

### What’s next * *passkey auth* replacing Privy (in review) * *earn module* (yield on idle balances) nearly done * *pots / budgeting allocations* work but getting another design pass * extra fiat ramps for redundancy * smoother one-click self-hosting (docker works now but could be simpler)

---

### How to try it * GitHub: https://github.com/different-ai/hyprsqrl * Live app: https://hyprsqrl.com — spin up a IBAN/ACH in seconds

Self-hosting still painful, but the rails are live—give it a whirl!

this seems really interesting, but I'm no up to speed on all the sconyms. what does this actually do? why would I want to use it? I think I understand that this is a tool to move money between fiat currencies using crypto. is that right?
Mortiffer•8mo ago
You can't have a bank account without a gov approved money manager account so you can't really self host it.

Also you can't on offramp crypto without a counter party will to make the trade ( liquidity )

Catchy title but I doubt it works was also vibecoded so I'd be extremely surprised if it works as advertised

cluckindan•8mo ago
So the idea is the same as Revolut: helping substance-dependent streamers skirt local taxes by letting online casino operated streaming sites pay their ”advertisers” in crypto fiat which is magically turned into clean dollars on a credit card?
