Nebeus

Nebeus is a Barcelona-based crypto-finance platform that has operated for over a decade and recently secured formal authorisation under the European MiCA (Markets in Crypto-Assets) regulation framework as a CASP (Crypto-Asset Service Provider) from Spain's CNMV (Comisión Nacional del Mercado de Valores). The platform is operated by Rintral Trading SLU and is part of Money-4 Limited, a company specializing in blockchain-integrated banking infrastructure. This regulatory path positions Nebeus as one of the first generation of platforms to achieve MiCA compliance, meeting what are widely considered Europe's highest standards for crypto business regulation.

The company maintains banking registration with Banco de España (Spain's central bank) under Registration Number D664, which gives it formal standing within the Spanish financial system. The MiCA CASP authorisation is the more recent credential: it grants Nebeus explicit permission to provide custodial services, exchange services, and transfer services for crypto-assets across all EU member states, with cross-border recognition built into the regulation. This is materially different from platforms operating under older frameworks or in jurisdictions with less developed crypto oversight. MiCA is the EU's unified regulatory standard and is designed to close loopholes that previously allowed lower-tier players to operate without equivalent scrutiny.

Nebeus operates two main account types for businesses. The Business Crypto Account is designed for companies that want to hold, manage, and exchange digital assets. The Business Crypto IBAN Account combines crypto capabilities with a traditional European IBAN, allowing businesses to receive and send fiat transfers via standard European banking rails while maintaining crypto holdings in the same ecosystem. This dual-account model is useful for crypto-native businesses that need both rails: they can accept fiat from customers or partners via IBAN, convert it to crypto if desired, and manage both in one platform without switching between services.

Beyond accounts, Nebeus offers several services built for business use. Business Loans allow crypto companies to borrow against their holdings without selling them, a feature that appeals to treasuries and operating entities that need cash flow but want to maintain their long-term crypto positions. Business Crypto Renting provides yield opportunities on held cryptocurrencies, letting businesses earn passive income on idle balances. The Mass Payout API is designed for companies that need to distribute payments to many recipients in fiat or crypto, useful for exchanges, platforms, and payment processors that operate at scale. The API-first design allows integration into other platforms and business workflows without manual transfers. Nebeus also offers exchange widgets that can be embedded into other platforms, letting businesses offer crypto trading to their users without building the infrastructure themselves or managing their own custody infrastructure.

The onboarding process for business accounts requires standard KYC documentation, similar to what you would provide to any regulated financial institution in Europe. Nebeus does not publish exact minimum balances on its public business account pages, but the platform operates with tiered account structures based on intended volume and the complexity of your use case. Communication with Nebeus about your specific business model is necessary to determine whether your profile and geography align with their underwriting standards. Many crypto business accounts have geographic restrictions, and while MiCA authorisation gives Nebeus EU-wide passporting rights, they may have internal policies about which jurisdictions and business models they onboard. This is typical for regulated financial services: regulatory approval is necessary but not sufficient, and individual platforms retain discretion over their customer base.

The regulatory foundation is worth examining closely. MiCA came into full effect in December 2024 and requires all crypto-asset service providers operating in the EU to achieve one of several authorisation pathways. Nebeus chose the CASP route, which is the most comprehensive. A CASP authorisation requires regular capital reserves, segregated client asset handling, thorough anti-money laundering protocols, and periodic regulatory supervision. This creates a meaningful compliance baseline that distinguishes MiCA-authorised providers from unregulated platforms or those operating under lighter-touch regimes in offshore jurisdictions.

The Barcelona location and Spanish regulatory domicile mean that Nebeus is subject to Spanish prudential oversight and EU-level MiCA supervisory coordination. The company must maintain specified levels of capital reserves relative to the risk of its business, keep client crypto and fiat in segregated accounts so that company insolvency does not put customer assets at risk, and undergo regular examination by regulators. These are the same obligations that apply to licensed banks in Spain, adapted for the crypto-specific business model.

The IBAN account is particularly practical for European businesses. It provides a standard European bank account number (IBAN) that can be used to receive transfers from any other European bank without the counterparty needing to know that crypto is involved. From the payer's perspective, it is a normal European bank transfer. From Nebeus's perspective, it is fiat held on a MiCA-authorised platform. This is useful for crypto companies that receive payments from traditional businesses, institutions, or individual customers who are not familiar with crypto wallets or who are instructed by their own banks to use only IBAN-based payments.

Pricing and fees are not prominently listed on the public website, which is common for business-tier accounts. Most of the specifics (exchange spreads, transfer fees, account maintenance costs, and API usage rates) are typically negotiated based on your business model, transaction volume, and account type. Crypto lending and yield products carry their own terms and rates. Contacting their business team directly is necessary to get accurate pricing for your specific needs.

Nebeus is most suitable for European crypto businesses and organisations that need both crypto and fiat capabilities within a single MiCA-compliant platform. The Barcelona headquarters and Spanish regulatory standing make it particularly accessible to businesses operating within Europe or seeking EU-regulated counterparties. The IBAN account option is valuable for businesses that receive payments from non-crypto sources and want to consolidate their banking without maintaining multiple accounts. The MiCA authorisation provides confidence in regulatory standing, though it does not eliminate the need to review Nebeus's own terms around which business models it accepts and any use-case restrictions they may have in place. If your business touches crypto in Europe and needs a genuinely regulated banking relationship with passporting rights across the EU, Nebeus is one of the few platforms with formal MiCA credentials and the infrastructure to match that standing.
