What “real-time payments” means in Croatia
In Croatia, “real-time payments” refers to the SEPA Instant Credit Transfer (SCT Inst) scheme, which processes euro-denominated payments almost instantly, 24/7/365. This system, known as EuroNKSInst, supports both domestic and cross-border transactions within the Single Euro Payments Area. The scope includes personal and business payments up to €100,000 per transaction between participating banks. While a specific local statute is not cited, the legal framework is fundamentally tied to EU regulations governing the SCT Inst scheme, ensuring alignment with pan-European standards.
The Croatian Financial Agency (Fina) operates the country's instant payment system, while the Croatian National Bank acts as a key regulator alongside the European Central Bank. Fina manages the EuroNKSInst clearing system, with final settlement occurring via the TARGET system. The system is built on the SCT Inst framework, which requires the ISO 20022 messaging standard (industry norm) for payment instructions. As of early 2025, all Croatian payment providers must be able to receive instant payments.
By adopting the SEPA framework, Croatia’s real-time payment infrastructure is now on par with its European counterparts, facilitating frictionless cross-border commerce.
Payment Rail Overview
EuroNKSInst
First initiated in October 2020, EuroNKSInst is Croatia's national real-time payment system operated by the Croatian Financial Agency (Fina). It functions as the domestic infrastructure for the SCT Inst scheme, processing euro-denominated payments in seconds, 24/7. The system allows for direct, near-instant transfers between accounts at participating Croatian banks.
- 24/7 Availability: The system operates continuously, processing payments on weekends and holidays without interruption.
- Near-Instant Settlement: Funds are transferred and credited to the recipient's account in as little as five seconds.
- High Transaction Limit: It supports individual payments up to a maximum of €100,000, accommodating a wide range of personal and business needs.
- Regulated Fees: By law, the cost for an instant payment cannot exceed the fee for a standard, non-instant credit transfer.
- Pro: Its rapid settlement time dramatically improves liquidity and cash flow for users.
- Pro: Constant availability offers significant convenience over traditional bank processing schedules.
- Con: Reach is limited to banks participating in the scheme, meaning it is not yet a universal service.
- Con: The transaction cap may be a constraint for very large corporate or commercial payments.
SEPA Instant Credit Transfer (SCT Inst)
SCT Inst is the pan-European framework that standardizes instant euro payments across 36 countries. Introduced for cross-border use in Croatia in June 2023, it provides the common rulebook that the domestic EuroNKSInst system follows. This makes instant payments from Croatia fully interoperable with the wider European payments network.
- Cross-Border Reach: The scheme facilitates instant euro transfers not just within Croatia but across the entire Single Euro Payments Area.
- Standardized Framework: It establishes a common set of rules and technical standards, creating a predictable and uniform payment experience across Europe.
- Mandatory Adoption: EU regulations mandate that all Croatian payment providers must support receiving instant payments by early 2025 and sending them by late 2025.
- Integrated Security: The framework requires robust security protocols, including daily compliance checks against official sanction lists.
- Pro: It integrates Croatia's payment system with the broader eurozone, simplifying international commerce.
- Pro: The mandated rollout guarantees that the service will become universally available across all Croatian financial institutions.
- Con: The implementation process is complex, requiring extensive coordination among all financial stakeholders.
- Con: Full functionality is subject to a phased rollout, with the ability to send payments not becoming universal until late 2025.
Limits, Fees, and SLAs
- Limits: A per-transaction cap of €100,000 applies to instant payments. Daily limits and distinct corporate tiers are not centrally defined at the system level.
- Fee Structures: Regulations mandate that fees for instant payments cannot be higher than for standard transfers. Individual banks determine their own rates.
- Operating Hours: The system is available 24/7/365, processing payments instantly on weekends and holidays with no specified cut-off times.
Compliance and Risk
KYC/KYB & AML
Croatian regulations, aligned with EU directives, mandate rigorous AML/KYC protocols. Financial service providers must conduct customer due diligence, perform daily sanction screenings, and report suspicious activities to the Financial Intelligence Unit (FIU) to prevent illicit financial flows.
Data Residency & Privacy
While specific data residency laws are not detailed, all financial data processing falls under EU and Croatian data protection rules. Firms must maintain secure records of customer information and transactions, making them available for review by supervisory authorities upon request.
Fraud Controls
Regulatory requirements focus on preventative security measures. Payment providers must implement robust internal controls, including daily database checks against sanction lists and mandatory reporting of any suspicious transactions to the national Financial Intelligence Unit (FIU) to combat financial crime.
Recordkeeping & Audits
Financial institutions are obligated to maintain comprehensive documentation of all customer due diligence activities and transaction histories. These records must be stored for a legally mandated period, ensuring they are complete and accessible for audits by regulatory bodies.
Lightning Network Integration as a Solution
The Lightning Network is a second-layer protocol on Bitcoin that processes transactions off-chain for faster, cheaper payments. While local RTP rails are confined to specific regions and currencies, Lightning provides a global, interoperable payment layer. It can extend the reach of real-time payments to international markets where traditional systems are limited, using Bitcoin as a universal settlement asset.
While Croatian RTPs offer settlement in as little as five seconds, Lightning transactions are also near-instant. The key differences are cost and reach. Lightning payments can cost mere fractions of a cent, making micropayments viable. More importantly, its reach is truly global, operating beyond the regional boundaries of systems like SEPA and connecting users worldwide without requiring traditional banking infrastructure.
- Cross-Border Complexity: The network bypasses intermediaries, reducing fees and delays for international payments.
- High Transaction Costs: Off-chain processing dramatically lowers fees, making micropayments and small-value transfers practical.
- Scalability Limits: It allows for millions of transactions per second, addressing the throughput constraints of the main Bitcoin blockchain.
For any organization pursuing global financial operations, the Lightning Network offers a direct and efficient architecture for the future.

Cross-Border Transactions and Remittances to Croatia
Cross-border RTP is complex due to fragmented systems. Reaching Croatia involves navigating varied FX paths, where currency conversions add cost and delay. True interoperability requires rail bridging—connecting disparate national payment systems, like SEPA, with international networks. This process is often slowed by high processing fees for international transactions and the operational overhead of meeting strict compliance and security checks for each country. These hurdles create friction, undermining the promise of instant global payments and increasing costs for businesses and consumers.
- Germany: As a top source of remittances, transfers from Germany benefit from Croatia's integration into the eurozone. Euro-to-euro payments are now treated like domestic transfers, avoiding FX margins and lowering costs significantly.
- Serbia: Payments from Serbia are classified as international transactions, as they originate outside the EU. These transfers require currency conversion from the Serbian dinar to the euro, typically involving higher fees and slower processing than SEPA payments.
- Australia: Remittances from Australia also fall into the international category, requiring conversion from Australian dollars. These transactions rely on traditional correspondent banking networks, which adds complexity and cost compared to the streamlined SEPA system.
The Lightning Network offers a powerful alternative by using Bitcoin as a neutral settlement asset. This architecture bypasses traditional banking intermediaries and FX conversion steps, creating a direct path for value that dramatically reduces both transaction time and cross-border processing fees.
