Simplex - the crypto rail you have most likely already used? A deep dive 2026
Lithuania's MiCA CASP fiat-to-crypto on-ramp gateway with 11 years of history, 350+ partners (Trust Wallet, KuCoin, Trezor) and parent Nuvei taken private in November 2024 for USD 6.3B. Fees 3.5-5% - and why it is still the EU standard.

If you have bought Bitcoin in the past five years through Trust Wallet, Trezor Suite, the KuCoin card, BitGet, Atomic Wallet or Changelly, the transaction was most likely processed by Simplex behind the scenes. We dig into what Simplex (Nuvei Liquidity, UAB) really is, what happened to parent Nuvei in 2024 (Advent International take-private for USD 6.3B), what a Simplex-processed purchase actually costs (3.5-5% per transaction + USD 10 minimum), and what the real risks are for users.
Simplex - the crypto rail you have most likely already used
If you have bought Bitcoin in the past five years through Trust Wallet, Trezor Suite, the KuCoin card, BitGet, Atomic Wallet or Changelly, the transaction was most likely processed by Simplex behind the scenes. It is a name barely known to direct retail users but one of the most significant regulated fiat-to-crypto «rails» in Europe, with 350+ partner integrations and a MiCA licence from the Bank of Lithuania.
In this deep dive we walk through what Simplex actually is, its history, what happened to parent Nuvei in 2024, what a Simplex-processed purchase actually costs and what the real risks are for users.

What Simplex is and how it got here
Simplex was founded in 2014 in Israel as SimplexCC Ltd. Its mission from the start was to solve one of the hardest fiat-to-crypto problems - how to accept card payments without chargeback risk. Card processors traditionally avoided crypto because Visa/Mastercard allow chargebacks for up to 120 days, while Bitcoin transfers are irreversible. Simplex's answer was AI-driven fraud detection with a 100% chargeback guarantee for partners.
In May 2021 Nuvei Corporation acquired Simplex for around USD 250M. In 2022 the company started operating in Lithuania under a PSD2 EMI licence.
The big 2024 pivot: Nuvei goes private
In November 2024 came a major change: Nuvei was taken private. Advent International (46%), former CEO Philip Fayer (24%), Novacap (18%) and CDPQ (12%) bought the company at USD 34 per share - a total deal value of USD 6.3 billion. Shares were delisted from the Toronto Stock Exchange on 18 November 2024 and from Nasdaq on 25 November 2024.
Practical implication: financial reports are no longer public. Before 2024 Nuvei published quarterly reports as a TSX/Nasdaq issuer. After the Advent deal this transparency disappeared - a real trust-side downside.
MiCA licence and the Lithuanian foundation
On 16 December 2025 the Bank of Lithuania granted Nuvei Liquidity, UAB (Simplex's Lithuanian legal entity) two licences: a MiCA CASP licence and a PSD2 EMI licence.
That makes Simplex Lithuania's third MiCA CASP - after Coingate and Robinhood. Simplex's legal address: Nuvei Liquidity, UAB, code 306127160, Lvivo g. 37-101, LT-09307 Vilnius.
What Simplex actually offers
- 200+ supported cryptocurrencies
- 100+ fiat currencies (including EUR, SEK, NOK, DKK, PLN)
- 190+ countries in total
- 350+ partner integrations
Payment methods: Visa, Mastercard, Apple Pay, Google Pay, SEPA, ACH, PIX, and 570+ alternative methods via the Nuvei platform.
Real fees - the honest view
| Service | Fee |
|---|---|
| Card purchase | 3.5-5% |
| SEPA purchase | 1.5-3% |
| Apple/Google Pay | 3.5-5% |
| Minimum fee | USD 10 |
Reality check: buying €100 of BTC by card through Simplex typically costs €5-7 in fees plus spread - similar to Bitpanda Simple/Instant Buy but materially more expensive than Bitvavo (below 0.5%) or Kraken Pro.
Security and compliance
- MiCA CASP licence (Bank of Lithuania, 2025-12-16)
- PSD2 EMI licence (Bank of Lithuania)
- AI-based fraud detection with 100% chargeback guarantee for partners
- AMF France whitelist
- Client funds segregation
- No publicly known security incidents since 2014
Simplex itself warns openly: «Simplex will never contact you directly about cryptocurrency purchases». If anyone calls or messages claiming to be Simplex, it is a scam.
Five risks worth saying out loud
1. Polarised Trustpilot reviews (~28,949). Positives praise speed; negatives flag non-delivery and slow support.
2. High fees - 3.5-5% per transaction with a USD 10 minimum.
3. Lack of transparency at Nuvei level after November 2024 - no public quarterly reports.
4. Brand-impersonation fraud - third parties pose as Simplex.
5. No retail trading platform - buy/sell only.
Who Simplex fits
A user already on an integrated crypto platform (Trust Wallet, Trezor Suite, KuCoin) - you probably already use Simplex under the hood.
A business with B2B integration needs - Simplex is a serious starting point.
Not a fit for investing, active trading, larger amounts, or users wanting low spread.
Alternatives
- Coinmotion - Finland's first MiCA CASP, ~1% fee
- Bitvavo - below 0.5% fees
- Kraken - global Pro standard
- Paybis Europe - newest LV MiCA CASP
- Coingate - Lithuania's oldest
Verdict
Simplex is not a scam - an 11-year-old B2B fiat-to-crypto on-ramp with a full MiCA + PSD2 EMI dual licence and parent Nuvei backed by the Advent International group. No publicly known security incidents.
But Simplex is an infrastructure player, not a retail exchange. For direct use the 3.5-5% fees are materially above Pro-exchange levels. The real value shows up in B2B integration.
If you see Simplex as a payment option in Trust Wallet or KuCoin Pay - it is a reliable choice. But for new investment or active trading - almost any other MiCA-licensed exchange will be materially cheaper.
Remember: Simplex never contacts you proactively. If anyone writes claiming to be «from Simplex», it is a scammer.
