The New Financial Infrastructure of the Web3 Era: When Wallets Become Payment Services

[TL;DR]

• Web3 payments face challenges with complex processes and high user drop-off rates. However, wallets are evolving beyond simple asset storage into integrated infrastructures offering on-ramps, payment, and settlement management.
• With WaaS (Wallet as a Service), businesses can now integrate Web3 payments using APIs without the need for complex blockchain development, making it possible to integrate with existing systems easily.
• Web3 wallets are establishing themselves as a new standard for financial infrastructure, driving innovative business models across NFT marketplaces, gaming, e-commerce, and membership services.

1. Current State and Issues in Web3 Payments

1.1 Complex Payment Processes and High User Drop-off

As the Web3 market rapidly expands, the demand for digital asset-based payments has surged. From NFTs and in-game assets to physical goods, cryptocurrency payments are becoming more common. However, the current payment processes remain surprisingly complex.

For example, if a user wants to purchase an NFT using Ethereum, the process typically involves the following steps:

1. Purchase Ethereum from a centralized exchange using fiat currency.
2. Transfer the purchased Ethereum to a personal wallet.
3. Connect the wallet to the NFT marketplace.
4. Complete the purchase.

If the user wants to pay using tokens from another blockchain, an additional bridging process is required, which introduces further complexity. Gas fees and network transaction costs also become extra burdens for the user.

This complicated flow leads to high user drop-off rates. Data from NFT marketplaces reveals that checkout conversion rates often fall below 30%. Cross-chain transactions further add to this complexity, requiring users to manage the bridging process manually while facing the risk of losing tokens due to mistakes.

Additional challenges include gas fee management and transaction failures, both of which degrade the user experience. For instance, during times of high congestion on the Ethereum network, gas fees can spike so drastically that they exceed the value of the purchase itself. Transaction times also vary, sometimes taking minutes or even hours compared to the near-instant processing of traditional credit card transactions.

These barriers create significant challenges for mainstream adoption of Web3 payments.

1.2 Challenges Businesses Face with Payment Integration

For businesses, adopting Web3 payment systems presents even greater hurdles. Key challenges include:

• Integration with existing payment systems: Connecting blockchain-based payments with traditional payment infrastructure is complex.
• Multi-chain and token support: Supporting multiple tokens and networks requires specialized development resources.
• Real-time settlement: Handling and tracking multiple on-chain transactions simultaneously can be resource-intensive.

Moreover, blockchain finality introduces unique risks. Once a transaction is executed, it cannot be reversed. This means businesses need to create robust error-handling mechanisms, which can demand significant development resources.

On top of that, varying settlement cycles and gas fee structures across different blockchains can complicate accounting processes.

Regulatory compliance further complicates the landscape. Different jurisdictions impose varying virtual asset regulations, including Anti-Money Laundering (AML) and Know Your Customer (KYC) requirements. Since Web3 transactions often occur across borders, meeting all these compliance standards can be challenging for businesses.

These challenges have limited the broader adoption of Web3 payments. However, emerging technologies and services, such as wallet-integrated payment services, are addressing these issues and unlocking new potential for Web3 transactions.

2. The Evolution of Wallets as Payment Infrastructure

2.1 The Paradigm Shift in Wallet Technology

Web3 wallets have undergone significant transformations. Initially, they were designed only for private key storage and basic asset transfers. However, they are now evolving into complete payment infrastructure tools.

The rise of DeFi and NFTs has made token swaps and NFT trading more common, requiring wallets to handle complex smart contract interactions.

A key change is the integration of financial services directly within wallets. Modern wallets now offer:

• On-ramps and off-ramps for buying/selling crypto with fiat currencies.
• DEX integration for direct token swaps within the wallet.
• Automated transaction handling for complex operations.

This evolution simplifies user onboarding by allowing fiat-to-crypto purchases directly in the wallet, reducing the need for external exchanges.
‍

2.2 Business-Focused Wallet Services

Wallet services for businesses have also matured. Previously, companies needed to manage their own crypto holdings and settlement flows manually. Now, wallets provide automated tools for handling these tasks, including:

• Multi-signature features for enhanced security.
• Customizable transaction limits.

These features have made institutional asset management safer and more efficient.
‍

2.3 Enhancing the Payment Experience

Account Abstraction (AA) and other innovations have significantly improved the Web3 payment experience. These technologies simplify complex approval processes, enabling a one-click payment experience similar to traditional online shopping.

Key advancements include:

• Gas Fee Optimization: Smart wallets can automatically adjust gas fees or let businesses cover them for a smoother user experience.
• Cross-Chain Payments: Automated token bridging and swaps allow users to pay with any token across multiple chains.

Despite these advancements, the expanding number of blockchains and tokens still poses a challenge. As a result, modern wallets are focused on abstracting complexity from the user while handling technical processes in the background.
‍

2.4 Wallets as Unified Financial Infrastructure

Today’s Web3 wallets are evolving into comprehensive financial platforms, supporting integration with traditional financial infrastructure:

• ERP Integration: On-chain transactions can sync with business accounting systems.
• Smart Contract Automation: Tokenized subscriptions, loyalty points, and installment payments can be automated.

The emergence of WaaS (Wallet as a Service) is accelerating this transformation. WaaS allows businesses to integrate Web3 payments through APIs without the need for in-depth blockchain development.

3. Real-World Use Cases for Web3 Payments

3.1 NFT Marketplace Payments

NFT marketplaces like OpenSea and Blur have integrated fiat on-ramps and direct payment processing, allowing users to purchase NFTs with credit cards. Wallets handle the crypto conversion and transaction processing seamlessly in the background.
‍

3.2 Web3 Gaming Payments

In Web3 gaming, wallets now support tokenized assets and in-game purchases with gasless transactions and automated token swaps. Games like Axie Infinity have integrated wallet services to simplify in-game economies and support real asset trading.
‍

3.3 E-Commerce & Loyalty Programs

Web3 payments have introduced stablecoin settlements for cross-border e-commerce, reducing fees and speeding up settlements. Tokenized loyalty programs are also gaining traction, enabling customers to use reward points across multiple platforms.
‍

3.4 Membership & Subscription Services

NFT-based memberships and tokenized subscriptions allow users to own and resell memberships with built-in smart contract automation for benefits and renewals.
