Banks, EMIs, Card Issuers, and Payment Infrastructure for Web3 Startups

The global financial system is undergoing one of the most significant transformations in modern history. Blockchain technology and digital assets are redefining how money moves across borders, how payments are processed, and how financial services are delivered.

Entrepreneurs around the world are launching new crypto exchanges, Web3 payment platforms, digital asset wallets, and stablecoin applications. These companies aim to build the next generation of financial infrastructure.

Yet for many founders, the biggest challenge is not building the technology behind these platforms.

It is banking.

Despite the rapid growth of the digital asset ecosystem, many crypto companies still struggle to access traditional financial infrastructure. Opening corporate bank accounts, securing payment processing capabilities, and integrating with global card networks can be far more difficult than building the blockchain product itself.

Understanding the financial infrastructure behind crypto companies is therefore essential for any founder building a Web3 fintech platform.

This guide explains the complete banking and payment ecosystem required to launch a crypto financial product.

Why Banking Is Essential for Crypto Companies

Even though cryptocurrencies operate on decentralized networks, crypto companies still rely heavily on traditional financial infrastructure.

Banks play a critical role in enabling digital asset companies to interact with the fiat economy.

Crypto companies need banking services to:

• process fiat deposits and withdrawals
• pay operational expenses
• manage treasury accounts
• settle payments through card networks.

Without access to reliable banking infrastructure, even the most innovative crypto platform cannot operate effectively.

For this reason, securing financial infrastructure is one of the first priorities for any digital asset startup.

The Four Core Layers of Crypto Banking Infrastructure

Launching a crypto financial product requires coordinating multiple types of financial institutions.

The infrastructure behind most crypto fintech platforms typically involves four key layers.

Layer 1: Banks

Traditional banks remain the foundation of the global financial system.

For crypto companies, banks provide essential services including:

• corporate bank accounts
• fiat reserves for customer funds
• payment settlement infrastructure
• treasury management.

However, many banks remain cautious about onboarding crypto companies due to regulatory uncertainty and compliance concerns.

As a result, only a limited number of financial institutions currently specialize in serving digital asset businesses.

Examples of banks that have worked with crypto companies include:

• AMINA Bank
• Bank Frick
• SEBA Bank
• LHV Bank.

These institutions have developed compliance frameworks designed specifically for digital asset companies.

Layer 2: Electronic Money Institutions (EMIs)

Electronic Money Institutions have become one of the most important components of the crypto fintech ecosystem.

Unlike traditional banks, EMIs do not lend customer deposits. Instead, they provide payment infrastructure that allows companies to hold electronic balances and process financial transactions.

Typical services provided by EMIs include:

• multi-currency accounts
• IBAN accounts
• payment processing
• international transfers
• financial APIs.

For many Web3 startups, EMIs provide the fastest path to obtaining banking infrastructure.

Popular EMIs supporting fintech startups include:

• MultiPass
• Transferra
• Satchel EU
• Payset
• FinXP
• Vialet.

These institutions provide the payment rails that allow crypto companies to interact with the traditional financial system.

Layer 3: Card Issuers

Many crypto fintech companies want to launch debit card programs that allow users to spend cryptocurrency through traditional payment networks.

These cards allow customers to convert crypto into fiat at the point of sale.

However, launching a crypto debit card requires partnerships with licensed card issuers.

Card issuers are financial institutions authorized to issue payment cards through networks such as Visa or Mastercard.

Examples of card issuers and card infrastructure providers used by crypto fintech companies include:

• Monavate
• Unlimit
• Verestro
• Baanx.

These institutions provide the infrastructure necessary for fintech companies to issue branded payment cards.

Layer 4: Payment Networks

The final layer connecting crypto companies to the global financial system is payment networks.

The two dominant networks are:

• Visa
• Mastercard.

These networks process billions of transactions every year and enable cards to be accepted at millions of merchants worldwide.

When a user spends cryptocurrency using a crypto debit card, the payment request flows through these networks to the issuing institution.

The crypto platform converts the digital asset into fiat currency, allowing the merchant to receive payment through traditional financial channels.

How Crypto Payment Platforms Work

To understand the importance of this infrastructure, it is helpful to look at how a crypto payment transaction works.

A simplified payment flow might look like this:

User Wallet
↓
Crypto Liquidity Provider
↓
Bank or EMI Infrastructure
↓
Card Issuer
↓
Visa or Mastercard
↓
Merchant

In this structure, each layer performs a specific function.

The crypto platform manages the user’s digital assets. The liquidity provider converts crypto into fiat. The bank or EMI provides settlement accounts. The card issuer connects the platform to payment networks.

Without these layers working together, crypto payment systems cannot function.

Why Crypto Companies Struggle With Banking

Despite the growing adoption of blockchain technology, many crypto companies still encounter difficulties when attempting to secure banking relationships.

Several factors contribute to this challenge.

Regulatory Complexity

The regulatory environment surrounding digital assets varies widely across jurisdictions.

Banks must ensure that companies operating in their ecosystem comply with applicable financial regulations.

If the regulatory framework governing digital assets is unclear or inconsistent, banks may hesitate to onboard crypto companies.

Financial Crime Concerns

Banks must comply with strict anti-money laundering regulations designed to prevent illicit financial activity.

Because cryptocurrency transactions can involve global transfers and pseudonymous wallet addresses, banks sometimes perceive crypto companies as presenting higher compliance risks.

Companies that cannot demonstrate strong AML and compliance systems are unlikely to secure banking partnerships.

Operational Risk

Crypto companies often process large transaction volumes and serve global customer bases.

These characteristics can create additional compliance and monitoring obligations for financial institutions.

Some banks therefore choose to avoid onboarding digital asset companies altogether.

Choosing the Right Jurisdiction

Jurisdiction plays a major role in banking relationships.

Companies operating in regions with clear digital asset regulations are generally more attractive to financial institutions.

Several jurisdictions have emerged as global hubs for crypto companies.

United Arab Emirates

The UAE has become one of the most important global centers for digital asset businesses.

Dubai’s Virtual Assets Regulatory Authority has introduced a regulatory framework specifically designed for digital asset service providers.

This environment has attracted exchanges, fintech startups, and blockchain companies from around the world.

Lithuania

Lithuania has established itself as a leading fintech hub in Europe.

The country offers access to the SEPA payment network and has issued numerous electronic money institution licenses to fintech companies.

Many EMIs serving digital asset companies operate from Lithuania.

Hong Kong

Hong Kong has introduced a licensing regime for digital asset trading platforms and continues to position itself as a regional hub for Web3 innovation.

Bermuda

Bermuda has adopted progressive digital asset regulations and has attracted several crypto financial institutions.

The Rise of Crypto Debit Cards

One of the most important innovations in the crypto fintech ecosystem is the emergence of crypto debit cards.

These cards allow users to spend digital assets through traditional payment networks.

When a user makes a purchase using a crypto card, the platform converts the digital asset into fiat currency and settles the transaction through Visa or Mastercard.

Crypto cards represent one of the most practical ways to integrate blockchain technology into everyday financial transactions.

The Future of Crypto Banking

The relationship between traditional financial institutions and digital asset companies continues to evolve.

As regulatory frameworks mature and compliance technologies improve, more banks are expected to develop specialized services for crypto companies.

At the same time, fintech infrastructure providers are building new tools designed specifically for the digital asset economy.

These developments are creating a new generation of financial platforms that combine blockchain technology with traditional banking services.
