Three ways to add stablecoin rails

Whether you want to build it yourself, need an expert alongside, or want it done for you. All roads lead to stablecoin payments live in your product.

01

The Playbook

Your team builds it. We give you the blueprint; architecture patterns, compliance templates, integration guides, and off-ramp setup. Built from our own production deployments across three jurisdictions.

Best for: CTOs with a dev team who want to move fast and stay compliant.
02

Consulting

Your team builds, we guide. Architecture review, regulatory strategy, integration support, and regular check-ins. We’ve navigated SEC, MiCA, and FINMA frameworks firsthand. You get the guardrails without the guesswork.

Best for: teams that need compliance confidence alongside technical guidance.
03

Done-For-You

We integrate stablecoin payment rails into your product end-to-end. Checkout, settlement, compliance, off-ramp, KYC. You focus on your product. We handle the payment infrastructure and ongoing operations.

Best for: teams that need it live fast and don’t want to build the rails themselves.

The Journey

Panche Isajeski
Panche Isajeski
Founder, Aristokrates

In 2021, I launched Kromatika, a crypto trading platform, under the pseudonym Aristokrates, Greek for “rule of the best.” A year later, the SEC named the token in a complaint filing as part of the Wahi insider trading case. I was not a party to the case, but the token was classified as an unregistered security. That experience showed me how wide the gap is between what builders create and what regulators expect.

In 2024, I started Blockia Labs in Tallinn, Estonia to bridge that gap. We helped fintechs and banks launch stablecoin and tokenization products, from first questions to working prototypes. Along the way, we built our own product accelerators: SDKs and APIs for identity, wallets, and payment flows. Not full products yet, but the building blocks for one.

As those building blocks matured, we saw a bigger opportunity. Stablecoins are changing how money moves across borders. AI agents are changing how businesses operate. We wanted to build at that intersection, full time. So the pseudonym became the company. Aristokrates was born out of Blockia Labs, and with it, our flagship product: AgentaOS.

Today Aristokrates helps companies add stablecoin payment rails to their products. DIY playbooks, consulting, or full done-for-you integration. Our own infrastructure, AgentaOS, powers it all underneath; checkout links, invoicing, EU IBAN, MPC wallets, 160+ countries. A fintech in Berlin or a marketplace in Lagos can accept stablecoin payments and settle in EUR without building it themselves.

Questions we get asked

Do we need a crypto license?

Depends on your architecture and jurisdiction. Non-custodial models are generally exempt from CASP licensing under MiCA. Different rules apply in the US (GENIUS Act) and Switzerland (FINMA). We’ve navigated all three firsthand and help you find the right structure; licensing, partnering with a regulated institution, or operating under an exemption.

Can users settle in fiat, not just crypto?

Yes. We connect to licensed e-money institutions with real IBANs and SEPA transfers. Users accept stablecoins; funds settle in fiat in their bank account. No manual conversion, no custody risk.

Why not BVNK, Circle, or Stripe?

If they work for you, use them. We work with companies that need non-custodial architecture, compliance across multiple jurisdictions, custom checkout flows embedded in their product, or operations in markets those providers don’t serve.

What jurisdictions do you cover?

EU (MiCA), US (SEC, GENIUS Act), and Switzerland (FINMA). Our founder went through SEC enforcement directly and has implemented MiCA compliance from day one. We also work with companies in Western Balkans, LATAM, and Africa where traditional payment processors are unavailable.

How long does it take to go live?

Depends on your starting point. If your team is building, the playbook gets you there in weeks. If you want us to do it, we’ve gone from first call to production in under a month. We’ll scope it on a call.

Do you work with companies outside fintech?

Yes. Marketplaces with international sellers, platforms paying contractors across borders, B2B companies doing cross-border invoicing, and brokers adding stablecoin deposits. If your product moves money and you need stablecoin rails, we can help.
