About TrustChange
Crypto-native engineering,
run like a regulated shop.
TrustChange is an EU engineering firm for digital assets and payments. We build exchanges, wallets, gateways and custody for teams under real supervision. Two skill sets rarely sit in one partner: deep crypto architecture and audit-grade delivery. Ours is built on both.
Since 2015
Payments first.
Digital assets from 2018.
Card and payment work taught us the delivery discipline. Digital assets came next. One team has carried both ever since.
How we build the plumbing-
2015

Rulebooks
Built against the regime that will examine the product.
Partner-led
Three founders. One of them owns your build.
No rotating bench. The architecture is designed and signed off by a founder, and the same person is still there at the audit after go-live.
Ilze Bērziņa

Ilze runs delivery for EMI, PSP and neobank platforms. She sets scope, team shape and the release discipline an auditor expects.

Tomáš Havel
Co-founder · Head of Compliance Engineering
Tomáš turns a licensing file into shipped code. Controls, evidence trails, and the reports a supervisor actually opens.

Engagement models
Buy the practice the way it fits your quarter. Fixed scope, a dedicated team, or two senior people inside a team you already run.
How the work runs
End to end, on one contract.
Discovery, architecture, build, hardening, launch and support. One group carries all six. Nothing is handed to a third party mid-flight.
See the full service list-
Discovery
We map the product, the rulebook and the risk. You leave with an architecture you own.
-
Architecture
A founder signs off the design. Threat model, data flows and key handling come first.
-
Build
Small senior teams ship in two-week slices. Every slice is reviewed and testable.
-
Hardening
Security review, load work and control evidence. We fix what the audit would find.
-
Launch & support
Handover to your team, then 24/7 cover. The code stays yours from day one.
Where we stand
Plain about what we are not.
- Not a hackathon studio. Every build targets production scale.
- Not a freelancer marketplace. You get a team with named accountability.
- Not generalists. Fintech and crypto are the whole practice.
- Not a white-label vendor. The product is bespoke, and you own it.
We also do not cut compliance corners to hit a date. That answer costs us deals. It is still the answer.
Regimes we build against
| Regime | Where it shows up |
|---|---|
| MiCA | Licensing-ready architecture and records |
| PSD2 | Strong customer auth on payment flows |
| AML / Travel Rule | Screening, KYT and transfer data |
| PCI DSS | Card data scope kept small by design |
| SOC 2 | Change control and access evidence |
| GDPR | EU data handling and retention rules |
Readiness is engineered in, never retrofitted. See how we handle compliance.
Next step
Bring us the hard part of your build.
Tell us the product, the deadline and the rulebook. A founder joins the first call. You get an honest read on scope and risk, not a pitch deck.
