Blockchain for Cross-Border Payments: The Essence

When used for cross-border payments, blockchain provides payment processing in seconds rather than days, drives a 40–80% reduction in transaction processing costs, and ensures topflight security and end-to-end traceability of payment-related data.

Cross-Border Payments on Blockchain: Market Info

Cross-border payments and settlements are considered the most prominent blockchain use case. According to the IDC Worldwide Blockchain Spending Guide, it accounted for 15.9% of the $4.67-billion blockchain market in 2021. With the expected growth of the global blockchain market from $7.18 billion in 2022 to $163.83 billion by 2029, the segment of blockchain-based cross-border payments is anticipated to show the corresponding increase.

Juniper Research estimates that B2B cross-border payments on blockchain will account for 11% of the total B2B international payments by 2024. The main driver for the popularity of blockchain payment solutions is their ability to provide fast, secure, transparent, and cost-effective processing of cross-border payment transactions.

How Blockchain for Cross-Border Payments Works

Architecture

It is blockchain’s innovative architecture that drives the advantages of blockchain-based vs. traditional cross-border payments.

Compared to international bank transfers, blockchain offers substantially lower transaction processing costs due to eliminated intermediaries (e.g., commercial banks, clearing houses, etc.). Plus, there are no cut-off times for payment processing, which results in drastically increased processing speed.

Compared to the independent e-payment systems such as PayPal or MoneyGram, blockchain provides much more robust security of sensitive data and eliminates the risk of data leakage. Also, blockchain money transfer is fully transparent, which contributes to the mutual trust between payers, payees, and cross-border payment service providers.

A sample architecture of blockchain-based cross-border payment solutions ScienceSoft delivers looks as follows:

Cross-border payment transactions are submitted by the blockchain network members or automatically enforced by smart contracts upon predefined events. The requested transaction is transmitted to the peer-to-peer (P2P) network of nodes that validate the transaction according to the selected consensus protocol. Traditional financial institutions and large businesses dealing with high-value transfers mainly rely on permissioned blockchains. In such networks, only known and trusted users with special rights can access and validate payment events and transactions. Fintech companies and SMEs focused on smaller-value B2B and C2B transactions usually opt for permissionless blockchains to promote financial inclusion and ensure maximized payment transparency.

Upon validation, payment-related data is encrypted with a hash function and stored in timestamped blocks linked chronologically. The blocks form an immutable ledger that provides a single source of truth to trace payment activities. Individuals, businesses, and financial services providers interact with a blockchain to make, receive, and monitor payments using role-specific web and mobile applications. All the participants maintain their own up-to-date copies of the distributed ledger.

A blockchain solution typically requires integration with financial data marketplaces and accounting software. Additionally, the solution may be integrated with:

  • Business-specific systems where payment initiation takes place, e.g., core banking software or ecommerce platforms.
  • A payment analytics system to share relevant data required to analyze cross-border payment transactions and payers’ behavior.

Main use cases

B2B cross-border payments

Key benefits:

  • Fast and secure global B2B payments, including high-value interbank settlements and P2P business payments.
  • Eliminated manual errors and payment delays due to cross-border payment automation.
  • Compliant financial reporting under different jurisdictions due to immutable records of payment-related data.

C2B cross-border payments

Key benefits:

  • Prompt and convenient international payments in crypto and fiat for individuals.
  • Low payment cost due to no need for third parties, such as governmental entities or financial institutions.
  • Minimized risk of security breaches.
  • Improved transparency and streamlined control of payment operations due to full visibility of money transfer transactions.

Key features

ScienceSoft creates blockchain-based cross-border payment software with unique functionality closely bound to the specific payment needs of each client. Here, we share a sample feature set of the blockchain solutions we create:

Real-time processing of cross-border payments

Blockchain offers near-instant processing of cross-border payments on a 24/7 basis with no involvement of intermediaries.

Multi-currency support

Blockchain can support cross-border payments in any cryptocurrency of your choice, including custom cryptocurrency.

Consensus-based validation of payment data

Blockchain provides rule-based validation of cross-border payment transactions and their prioritization for processing and storage. The rules are defined by the selected consensus protocol.

Automated recordkeeping

Upon successful validation, payment transactions and relevant data from the connected systems (e.g., data on currency exchange rates) are automatically timestamped and recorded in the immutable ledger.

Full traceability of cross-border payments

The blockchain ledger enables real-time monitoring and end-to-end traceability of cross-border payments for the blockchain network members.

A comprehensive audit trail of payment-related documents

Blockchain keeps an immutable record of all manipulations across payment-related documents (invoices, receipts, letters of credit, etc.): document creation, editing, sharing between the parties, viewing, and more.

Payment automation enabled by smart contracts

Smart contracts contain the rules for triggering and automated enforcement of particular cross-border payment transactions. For example, they can initiate automated payment to the foreign service provider upon service delivery.

Payment security

Security of the blockchain payments is achieved via payment data hashing, transaction e-signing with a unique digital signature, multi-factor authentication, including biometric authentication (e.g., facial or fingerprint recognition), fraud detection algorithms, and more.

Success Stories of Blockchain for Cross-Border Payments

Banco Santander Benefits from Faster and Cheaper Cross-Border Transactions

In 2018, Banco Santander, a banking giant serving 140M+ customers worldwide, partnered with Ripple to launch One Pay FX, a blockchain mobile app for cross-border payments. The innovative solution offers automated currency conversions, provides real-time processing of cross-border payments, maintains an immutable record of all transactional data.

With the help of blockchain, Banco Santander managed to reduce the processing time for international bank transfers from 3–5 days to seconds and substantially decrease the fees for cross-border transactions. Also, the bank saw enhanced customer satisfaction due to full transparency of FX rates and transactional flow.

One Pay FX currently enables fast, low-cost payments to two dozen countries. The solution has the potential to handle 50% of Banco Santander’s international payment transactions.

The Challenges of Blockchain for Cross-Border Payments

Many business owners and executives still have doubts regarding blockchain’s ability to address certain operational and regulatory aspects of cross-border payments. But having years of expertise in blockchain development, we know how to solve the potential challenges safely and cost-effectively.

Challenge #1: Compliance with anti-money laundering regulations

Blockchain needs to provide compliance with global and region-specific AML/CFT regulations, including KYC, CDD, and FATF requirements, to prevent illicit payments and money laundering.

SOLUTION

Solution

ScienceSoft usually develops dedicated smart contracts to run compliant customer identity verification and risk assessment automatically. Smart-contract-based automation can help you eliminate complex, error-prone manual tasks across the initial KYC verification and customer information cross-checking upon changes. It also significantly speeds up further client authentication in the blockchain network.

HIDE

Challenge #2: High crypto volatility

Some blockchain solutions rely on the “fiat-crypto-fiat” model of cross-border payments. Under this model, blockchain employs cryptocurrencies as the bridge between the payer’s fiat currency and the payee’s fiat currency. However, continuous – and considerable – fluctuations in cryptocurrency prices pose the risk of losing the crypto funds value during currency conversion and transaction processing. The blockchain solution needs to address this risk.

SOLUTION

Solution

Consider using fiat-backed stablecoins as on- and off-ramps to move from fiat to crypto and vice versa. This step offers a risk-free way to access crypto liquidity while eliminating the conversion losses.

HIDE

ScienceSoft’s expert tip: Coding the rules for the automated currency conversions in smart contracts helps significantly speed up cross-border payment processing.

Challenge #3: Continuous data upload from off-chain sources

Blockchain for payment needs to instantly access the data provided in payment-related documents, as well as up-to-date currency exchange rates for crypto and fiat. These data are essential for accurate processing and recording of cross-border payment transactions. Thus, the solution has to be seamlessly integrated with the relevant external data sources.

SOLUTION

Solution

Easy-to-use integration APIs help ensure fast and smooth blockchain connection to relevant corporate data sources (e.g., an enterprise’s accounting system or core banking software). And blockchain oracles enable real-time import of market-available financial data to blockchain smart contracts.

HIDE

Costs of Blockchain-Based Cross-Border Payment Software

Major factors that affect the cost and duration of the development are:

  • The solution’s functional complexity.
  • The number and complexity of smart contracts needed to introduce cross-border payment automation.
