Key Facts for Bulgaria
- Primary real-time rails: Blink, BISERA, TIPS.
- Typical settlement times: Interbank transfers are executed within 10 seconds.
- Common limits: Varies by institution.
What “real-time payments” means in Bulgaria
In Bulgaria, “real-time payments” refers to instant transfers processed through the Blink system for the local currency (BGN) and the TARGET Instant Payment Settlement (TIPS) service for euros. Blink executes domestic interbank transfers within 10 seconds, operating 24/7. The system’s reach is substantial, with over 90% of the country’s bank accounts accessible. While no single statute provides a legal definition, these payment rails function under national and EU financial regulations, ensuring alignment with European standards for security and transparency. The scope includes both individual and business payments, with certain exclusions like recurring transfers.
The Bulgarian National Bank is the lead financial regulator, while BORICA AD operates the core payment infrastructure, including the BISERA national clearing system and its instant payment component, Blink. In late 2024, the national system also joined the TIPS service, connecting it to the Eurosystem for instant euro transactions. The relevant messaging standard is ISO 20022 (industry norm), which provides a rich, structured data format for payments and is a prerequisite for participation in pan-European systems like TIPS.
Bulgaria has developed a highly adopted domestic real-time payment system and is now strengthening its global connections by integrating with broader European networks.
Payment Rail Overview
Blink
Blink is Bulgaria's domestic instant payment system for transfers in the local currency, the Bulgarian Lev (BGN). Introduced around 2021, it allows individuals and businesses to send money between participating banks in seconds, operating around the clock. The system is a component of the national payment infrastructure managed by BORICA AD and has seen rapid adoption.
- Real-time settlement: Transfers are completed within 10 seconds, providing immediate access to funds.
- Constant availability: The service operates 24/7/365, including on weekends and public holidays.
- Broad access: Over 90% of Bulgarian bank accounts are reachable through the Blink network.
- High adoption: The system processed over 22 million payments in 2024, marking a 102% year-over-year increase in volume.
Pros
- Instant settlement for BGN payments.
- High availability and wide reach within Bulgaria.
- Supports both individual and business transactions.
Cons
- Limited to domestic transfers between participating institutions.
- Does not apply to certain payment types like recurring bills or direct debits.
TIPS
TIPS is the Eurosystem’s service for settling instant payments in euros, which the Bulgarian market joined in December 2024. It allows Bulgarian banks to process cross-border euro transactions instantly, settling them in secure central bank money. This integration is a key step in aligning Bulgaria’s financial infrastructure with the broader euro area.
- Euro settlement: Specifically designed for processing instant payments denominated in euros.
- Central bank money: Transactions are settled in central bank money, offering a high degree of security.
- Pan-European network: Connects Bulgarian banks to the wider European network of TIPS participants for instant transfers.
- Continuous operation: The platform functions around the clock, every day of the year, without downtime.
Pros
- Enables instant euro payments across Europe.
- High security through settlement in central bank money.
- Supports Bulgaria’s financial integration with the euro area.
Cons
- The system is specific to euro-denominated transactions.
BISERA
BISERA is Bulgaria's established national clearing system for domestic bank transfers, operated by BORICA AD. While its primary function is processing large volumes of payments like salaries and utility bills in batches, it serves as the foundational infrastructure for the Blink instant payment program. As of late 2024, the BISERA system is also connected to the pan-European TIPS network for instant euro payments.
- National clearing system: Acts as the core infrastructure for processing domestic interbank payments in Bulgaria.
- Bulk payment processing: It is built to reliably handle large-scale, non-urgent transfers for businesses and government entities.
- Instant payment integration: The system incorporates the Blink program for real-time BGN transfers and is connected to TIPS for instant euro payments.
- System reliability: It is a trusted and secure system for daily fund movements within the Bulgarian banking sector.
Pros
- Highly reliable for large-volume, non-urgent domestic payments.
- Serves as the backbone for both domestic and European instant payment services.
- Trusted by banks and businesses as a core part of the financial system.
Cons
- Core processing is batch-based, which can result in delays for non-Blink transactions.
- Its speed for urgent payments is dependent on integrated systems like Blink, not the base system itself.
Limits, Fees, and SLAs
- Limits:Transaction caps vary by bank. For example, UniCredit Bulbank sets a limit of BGN 30,000 per transfer via its mobile app.
- Instant Payment Fees:Charges are typically the same as for a standard BGN transfer, based on the bank’s tariff for fees and commissions.
- Operating Hours:Instant payment services are available 24/7/365, including on weekends and holidays, with no specified cut-off times.
- Failures & Returns:If a payment cannot be processed instantly, the sender is notified and must re-initiate the transaction as either instant or a standard BISERA transfer.
Compliance and Risk
KYC/KYB & AML
Bulgaria's framework, aligned with EU directives and the local AML Act, mandates rigorous customer due diligence. Firms must identify customers, monitor transactions, and report suspicious activity to the Financial Intelligence Directorate, ensuring a high standard of integrity in financial operations.
Data Residency & Privacy
While specific data residency laws aren't detailed, financial operations fall under EU GDPR standards. Access to account information is strictly controlled, requiring customer consent for third-party services and legal processes for government access, upholding data confidentiality.
Fraud Controls
Regulatory guidelines focus on preventative measures through stringent identity verification and transaction monitoring. Financial institutions must report suspicious activities to national authorities, creating a system of vigilance that protects the integrity of the payment network and its users.
Recordkeeping & Audits
Financial service providers are required to maintain comprehensive records of customer due diligence and transactions for a minimum of five years. This practice supports regulatory oversight and ensures that a clear, auditable trail is available for review by authorities.
Lightning Network Integration as a Solution
The Lightning Network is a second-layer protocol on Bitcoin that processes transactions off the main blockchain, making them fast and inexpensive. While local RTP rails like Blink excel at domestic payments, they often stop at the border. The Lightning Network can act as a global settlement layer, connecting these isolated systems to facilitate instant, low-cost international payments and extending the reach of real-time transfers worldwide.
Compared to domestic rails, the Lightning Network offers comparable or faster settlement times, often in seconds. Its transaction costs are significantly lower—typically fractions of a cent—making micropayments viable. While local systems provide extensive domestic coverage, the Lightning Network’s primary advantage is its global reach. It operates as a borderless payment infrastructure, connecting users worldwide without relying on traditional banking intermediaries for international transactions.
- Cross-border Complexity: It simplifies international payments by removing intermediaries and bypassing traditional banking delays.
- High Transaction Fees: Its off-chain model results in minimal fees, making micropayments and small-value transfers economically practical.
- Limited Global Reach: Unlike domestic RTP systems, which often have weak global connections, it provides a worldwide payment infrastructure that connects markets with limited financial access.
Exploring the Lightning Network opens a path to a truly global and efficient payment future.

Cross-Border Transactions and Remittances to Bulgaria
Cross-border real-time payments to Bulgaria face significant friction. While domestic systems are fast, international transfers are slowed by regulatory mismatches and expensive FX paths. Reaching the country efficiently requires effective rail bridging—connecting Bulgaria’s local payment infrastructure to global networks. This operational complexity creates delays and adds costs, hindering the potential for truly instant, borderless transactions. The challenge lies in unifying these separate systems into a single, fluid network for moving money globally.
- Pan-European (SEPA/TIPS): Euro payments are standardized but can be slow, while the integration with TIPS allows for instant euro transfers. This corridor is vital for remittances, which totaled $2.67 billion in 2024, largely from Bulgarians in other EU nations.
- Global Payment Platforms: Modern platforms provide instant transfers to over 70 countries by bridging local and global rails, bypassing traditional banking intermediaries. These are ideal for remittances and global payroll, offering real-time salary payments to international workers.
- Traditional Bank Transfers: Any transfer exceeding BGN 30,000 requires extensive documentation and declaration to the Bulgarian National Bank. This regulatory process adds administrative friction and potential delays for large-value remittances and business payments.
The Lightning Network functions as a universal settlement layer, bridging disparate payment systems across the globe. It uses Bitcoin to move value instantly and for extremely low fees, bypassing the delays and high costs of traditional correspondent banking.
