Registry Integrations: How Soldera Integrates, Proprietary but Provable

We can’t help it - Soldera is drawing scepticism. Our registry connections include some of the hardest. As a platform, we’re integrated with very technically challenging registries - and the absence of an API is no deterrent for us. In Europe, our platform integrates to nearly all national government-operated energy certificate registries and continues to connect to more. Current connections include: Belgium (x4), Croatia, all Baltic states, all Nordic states, Germany, Italy, France, Greece, Netherlands, Hungary, Portugal, Sweden, Poland, The U.K. and Bulgaria, with more and more registries arriving by the month. But there’s an issue - we can’t tell you how.

Why Soldera expects scepticism.

When a buyer hears that one software platform can operate across registries, especially the ones that do not behave like modern software products, but rather as archaic government portals, the scepticism is honestly fair. These registries were not an easy feat, after all, and Soldera has built its registry layer through years of registry-by-registry work, with custom handling for different national processes rather than any singular method - not possible given that all markets are unique. This case-by-case approach only works if you have unusually strong technical execution behind it, which is why Soldera keeps stressing the importance of hiring engineering talent. The team includes people with experience from Trimble and LHV, and the business has had grant backing alongside venture funding to keep pushing the integration layer forward.

But we’re now left in an interesting position. On a recent call with a potential end-user considering Soldera as their registry infrastructure layer, the reaction to Soldera's ability to connect into the German registry was this:

“extraordinary claims require extraordinary proof”.

If you want proof, use the platform!

Don’t get us wrong: we welcome scrutiny, and we’re always receptive to true user criticism, given it’s one of the few guaranteed ways to make our product better. However, we’re running into this “proof” issue when prospective users are seeing Soldera for the very first time , even in demos. That leaves us genuinely scratching our heads as to what proof should look like in this market. Our best answer is: usable outcomes. Try it yourself!

Of course, some things stay secret.

Every serious software infrastructure business has internal methods it does not publish line by line, and registry integration is one of those subjects where keeping the method private matters commercially to Soldera. We’re just not showing our codebase to you on a discovery call.

Thankfully, provable usability matters more. The proprietary part is not the claim buyers should care most about: we don’t think a corporate user needs a lecture on connector architecture - but instead needs to know whether certificates can actually be sourced, transferred, cancelled, and turned into documentation that’s ready for an audit. Even if we felt we could show you a clever story about our integration, surely the smart move isn’t just to trust us, it’s to verify yourself. The real test then comes down to whether or not you can use the system, inspect the outputs, and check the workflow independently. Of course, this is possible as soon as you sign up.

Why are registry integrations so difficult to trust in the EAC market?

Some market participants will, for at least a while longer, continue to think of the EAC market as something that still runs on fragmented infrastructure, uneven workflows, and standalone registries, each with their own quirks. Until they try Soldera, they’ll keep defaulting to thinking that the set of cross-border challenges we’ve already solved are still the frontier problems of the market. We don’t blame them, but we do ask this: give our solution a chance to change your mind.

What buyers can verify independently with Soldera:

• Hard registries like Germany are handled, even without friendly public APIs.
• Our demos are real. As soon as you create an account certificates move through real registry workflows, not a mock-up or test-net.
• Traceable evidence can be exported, including registry-backed cancellation documentation.
• Soldera’s API can be used independently - just sign up and ask. The API can be made available for counterparties who want to test the integrations for themselves.

If a buyer needs one interface across Energy Attribute Certificate markets , including hard-to-crack jurisdictions, while still ending with exportable cancellation documentation instead of vague assurances or proxy certificates, Soldera is the platform for them.
