What does DeFi mean in the context of payments?

DeFi in payments refers to a model where transactions are executed via programmable digital infrastructure, combining payment processing with identity verification, risk assessment, and financing decisions. It goes beyond crypto by integrating data, automation, and conditional logic directly into the payment flow.

Will DeFi replace traditional payment systems by 2040?

No. The more realistic scenario is a hybrid model where regulated payment service providers, digital identities, tokenized money, and programmable logic work together. Traditional infrastructure will remain relevant as a trust anchor, especially in regulated markets like the EU.

How will DeFi change the checkout experience for merchants?

Checkout will evolve into a decision layer where identity, risk, and payment approval are handled in real time. This reduces friction, enables dynamic payment options, and improves conversion by tailoring the payment experience to each transaction.

What are programmable payments and why do they matter?

Programmable payments are transactions that execute automatically when predefined conditions are met. For merchants, this enables use cases such as automated marketplace payouts, conditional B2B payments, and more efficient handling of refunds or partial cancellations.

What role does digital identity play in future payments?

Digital identity enables secure, real-time verification directly within the payment flow. With solutions like the European Digital Identity Wallet, merchants can reduce manual input, improve compliance, and request only the necessary data for each transaction.

How does real-time data improve payment and credit decisions?

Real-time payment data allows for more accurate risk assessment and dynamic financing decisions at checkout. This enables merchants to offer tailored payment options based on customer behavior, transaction context, and risk profile.

What should merchants do today to prepare for DeFi-driven payments?

Merchants should focus on building API-driven, interoperable payment infrastructure, improving data quality and consent management, and piloting use cases like programmable payments or real-time credit. Working with regulated partners is critical to ensure scalability and compliance.

Fintech 2040: DeFi and the Future of Payments

For payments, this primarily means three things:

More real-time processing

More automation

More decision-making within the payment flow

Why is this relevant now? Because the foundations are already shifting. In the EU, payment service providers that send and receive transfers must also offer instant euro payments. At the same time, MiCA, the EUDI wallet, and the Eurosystem’s payments strategy are establishing the regulatory and technical framework for standardized, interoperable, and innovation-ready digital payment models. Meanwhile, market players are integrating stablecoin and wallet-based payments into real commercial offerings.

This does not mean merchants should move their entire checkout onto public blockchains. DeFi remains a niche topic in the EU. A hybrid future is more likely: regulated PSPs, tokenized forms of money, digital identities, open standards, and programmable payment logic working together.

For merchants, the key question is not whether something is “pure DeFi,” but whether a payment becomes faster, safer, smarter, and better integrated into their business model.

What Is DeFi in Payments?

In payments, DeFi is not just about crypto wallets or stablecoins. It refers to a model where value, identity, risk, and compliance checks are more tightly integrated. Payments can be triggered automatically when predefined conditions are met. Identity credentials can be requested from wallets. Payment data can feed into real-time risk or financing decisions.

This combination of programmable execution, digital credentials, and data-driven decision-making is what makes DeFi relevant for payments.

For merchants, the more important shift is this: DeFi changes not only the payment rail but also the role of checkout. Checkout becomes the point where identity is verified, risk is assessed, financing is approved, payment terms are communicated, and post-processing is prepared.

Modern payment flows already reflect this—through additional KYC data, strong customer authentication, legal disclosures, and automated status updates back to merchant systems.

Key Payment Trends Shaping 2040

1. Identity-Driven Payments

The EUDI wallet will be built on shared European standards, while EMVCo is already working on payment use cases for in-store and online payment initiation and authentication. In parallel, the W3C is standardizing web mechanisms that allow websites to request credentials directly from wallets.

For merchants, this means fewer form inputs, fewer disruptions, and ideally only the data required for a specific transaction—for example, age verification instead of a full ID document.

2. Real-Time Credit in the Payment Flow

Open banking and open finance are making payment data more portable and useful. The BIS highlights that digital payment data can provide high-frequency, verifiable insights that improve credit assessment and monitoring.

A World Bank analysis across 101 economies shows that firms receiving electronic payments are less likely to face credit constraints—especially small, young, or hard-to-assess businesses.

By 2040, payments and financing will likely be tightly integrated—not after the purchase, but at the moment of purchase.

For merchants, the impact is clear: payment options will no longer be static but dynamically determined based on identity, payment behavior, account data, basket composition, category, market, and risk.

3. Programmable Payments

The ECB defines programmable payments as payments executed automatically when predefined conditions are met. The Eurosystem highlights standardization, automation, process integration, and conditional payments as key objectives.

In practice, this means:

Marketplace payouts triggered after confirmed delivery

B2B payments tied to goods receipt or milestone validation

Automated refunds, partial cancellations, and collateral handling

4. Trust as Infrastructure

In traditional systems, trust was concentrated in institutions and manual processes. In the new model, trust increasingly shifts into systems, rules, and shared data models—but it does not disappear from institutions.

The BIS emphasizes that a functioning monetary system requires a credible trust anchor and institutional backing of the “singleness of money.” The ECB makes the same point: central bank money remains the anchor of the financial system.

For merchants, this means trust becomes more system-driven—but only becomes scalable through regulated, interoperable infrastructure.

Payments Become a Trust and Decision Layer

The most important shift is conceptual. A payment is no longer just the transfer of money from A to B. It becomes a decision point:

Who is paying?

Under what conditions?

What level of risk is acceptable?

What data can be shared?

When is the payment final?

Payment infrastructure evolves into a layer for identity, trust, credit, compliance, and business logic.

What This Means for Merchants

First, payment strategy becomes product and margin strategy. Payments now directly influence conversion, fraud costs, returns logic, working capital, and international scalability.

Second, data quality and consent management become competitive advantages. Open finance requires standardized, portable, and trustworthy data.

Third, post-purchase processes become part of the payment architecture. Reconciliation, refunds, installments, dunning, and receivables management must keep pace with more flexible and data-driven payments.

The Challenges Remain Real

Interoperability remains a key barrier. While interoperability increases adoption, blockchain ecosystems can fragment.

Regulation is another constraint. MiCA provides a framework for crypto-assets, but DeFi itself is still under regulatory observation in the EU.

Data quality and security are ongoing concerns, including smart contract risks, wallet vulnerabilities, and user complexity.

For merchants, the implication is clear: less hype, more robust infrastructure.

Riverty’s Role in This Future

Riverty’s strength lies in being an infrastructure partner for a hybrid payment future.

Its capabilities—flexible payment methods, hosted checkout, identity verification, real-time risk scoring, regulated processing, invoicing, reconciliation, and debt collection—align directly with this evolution.

Merchants need a bridge from today’s payment flows to future hybrid models.

What Merchants Should Do Now

Analyze checkout as a decision layer: identify friction between identity, risk, payment authorization, and reconciliation

Invest in interoperable, API-driven infrastructure

Build readiness for wallets and digital identity

Pilot a programmable payment use case (e.g., marketplace payouts or B2B milestone payments)

Work with regulated infrastructure partners

Future proof

By 2040, the most successful merchants will not be those who adopt every new payment rail first. They will be those who understand payments as a trust, data, and decision infrastructure—and use it to create better customer experiences, faster processes, and more resilient margins.

DeFi is not an end in itself. But it is a strong signal of where payments are actually heading.
