Guardarian

Guardarian is a non-custodial fiat-to-crypto and crypto-to-fiat exchange platform that launched in 2017 and now operates primarily through GRNTech Solution Inc., a Canadian Money Services Business registered with FINTRAC, alongside a sister entity FinSeven CZ s.r.o. registered in the Czech Republic. The platform is positioned as a fiat on-ramp and off-ramp rather than a destination exchange, letting users buy, sell, and swap crypto without creating an account or moving funds into a custodial wallet on Guardarian’s side; assets are sent directly to the user’s own wallet on completion of an exchange.

Through Guardarian, retail users can convert between 250+ cryptocurrencies and over 50 fiat currencies using bank cards (debit/credit), SEPA and other bank transfers, and a range of regional payment methods. Beyond direct retail flows, Guardarian offers a B2B product range under the G-Products umbrella, including G-Payments (crypto payment processing), G-Custody (asset custody for businesses), G-OTC (over-the-counter desk for larger trades), and G-Swaps. Partners can integrate via a customisable embeddable widget or via the documented public API at api-doc, and earn affiliate revenue on referred volume.

Operating as a regulated entity in Canada and the Czech Republic, Guardarian is subject to standard money-services AML and KYC requirements: while the trading flow itself is non-custodial, identity verification is applied above defined transaction thresholds in line with FINTRAC and EU rules. The exchange’s stated fee model is a transparent 2.49 EUR (or local-currency equivalent) flat handling fee per transaction in addition to the embedded rate spread, with no separate maker/taker schedule. The Guardarian product targets users and businesses that want a simple, fiat-anchored on/off-ramp without taking on the custody and order-book complexity of a traditional spot exchange.
