Contact
One email, and an architect
answers you directly.
TrustChange builds and scales regulated digital-asset products. Write to us about the exchange, wallet, custody or payment system you need. A senior engineer reads it. You get an architecture view back, not a brochure.
- EU-based engineering team
- NDA before scoping
- Architects on the call
Pick your route
Three ways teams start with us
Most enquiries land in one of three shapes. Say which one fits. We route your note to the right architect on the first pass.
-
Scope a build
You have a product to ship
Send the shape of the product. We reply with an architecture sketch and a build sequence.
Best for exchanges, wallets, custody and payment rails.
-
Add engineers
You have a team that needs depth
Tell us the gap. We name the seniority, the stack and how fast people can start.
Best for in-house teams under a launch deadline.
-
Compliance review
You have a licence to satisfy
Share the regime you sit under. We map where MiCA, PSD2 and AML duties hit the build.
Best for VASPs, PSPs, EMIs and neobanks.
After you write
What the first week looks like
No funnel, no drip sequence. Four steps, in order, run by the people who would do the work. You can stop after any of them.
Want proof first? Read the case studies or our compliance approach.
-
We read it
A senior engineer reads your note first. No qualification script, no discovery form.
-
NDA, if you need one
We sign your NDA before any detail is shared. Ours is ready if you prefer it.
-
Discovery call
We walk your target architecture, the compliance surface and the risky parts.
-
Written assessment
You get the target design, a milestone order and the engagement model that fits.
Before you send
Five lines make the first reply useful
None of this is required. It just lets an architect answer with substance instead of questions.
- The product you want live, in two or three sentences.
- The regime you operate under, or the licence you are chasing.
- What already exists: code, vendors, ledgers, or nothing yet.
- Your target launch window and any board or investor date.
- Who owns the decision on your side.
Building on top of an existing stack? Point us at it. See how we handle wallet and custody work and payment gateways.
Before the call
Questions we get on day one
Do you work with early-stage crypto startups?
Yes. We build for funded startups and licensed firms alike. The bar is production intent. We do not run hackathon or prototype projects.
Can you join a build that has already started?
Often, yes. We review the current design and name the risks we see. Then we scope the smallest useful first step.
Which engagement model should I ask for?
Ask for the outcome instead. We propose the model that fits: fixed scope, a dedicated team, augmentation, or CTO advisory.
What if my compliance picture is still unclear?
That is normal. Send what you know. Our compliance engineers map MiCA, PSD2 and AML duties onto the architecture with you.
Start with the hard question
Send the part of the build that worries you most. Matching engine load, key custody, reconciliation, or the licence deadline. That is the conversation we are best at.
