The adoption of Web3 technology is accelerating, with both cryptocurrency-focused companies and traditional Web2 brands launching products and experiences that incorporate Web3 components like NFTs, decentralized finance, or metaverse environments. However, the process of onboarding users into Web3 remains challenging, largely due to the complexity associated with cryptocurrency and Web3 wallets.
From managing seed phrases to handling multiple wallets for different blockchains, the user experience often falls short. This friction poses a direct threat to broader adoption.
Wallet-as-a-Service (WaaS) solutions aim to address these challenges by allowing brands to seamlessly integrate user-friendly cryptocurrency wallets directly into their platforms.
Understanding Wallet-as-a-Service
Wallet-as-a-Service refers to solutions that provide ready-made cryptocurrency wallet integration for applications and platforms. By choosing a WaaS provider, companies can bypass the complexities of key management, security, and infrastructure while still offering a fully functional wallet to their users.
These providers ensure enterprise-grade security and compliance with financial regulations, allowing businesses to focus on their core offerings rather than technical nuances.
Ultimately, integrating a Wallet-as-a-Service solution accelerates time-to-market and provides essential transaction capabilities and digital asset storage to end users.
How a Wallet-as-a-Service Provider Works
A typical WaaS provider operates through several core components that work together to deliver a seamless experience.
API Integration
API integration connects the Wallet-as-a-Service platform with a business's existing systems or third-party services. This connectivity enables various essential functionalities:
- Wallet operations: Facilitates Web3 wallet creation, transactions (including payments, transfers, and exchanges), and real-time balance checks through simple API calls.
- Customization and flexibility: Allows businesses to tailor the wallet experience, including user interface elements, loyalty programs, and specific features, to match their unique requirements.
- Scalability: Supports business growth by handling increased transaction volumes and user numbers without requiring major infrastructure changes.
Backend Infrastructure
The backend infrastructure of WaaS providers is designed to ensure seamless operation, security, and scalability:
- Database management: Utilizes secure, high-performance databases to store user data, transaction records, and wallet balances, optimized for quick access and efficient transaction processing.
- Transaction processing engine: Serves as the core component that handles transaction initiation, monitoring, and status updates on the blockchain, often including fee estimation and security features like address whitelisting.
- Security and compliance: Prioritizes security through encryption and multi-factor authentication while providing tools to comply with anti-money laundering (AML) and know-your-customer (KYC) regulations.
User Interface
WaaS providers typically offer customizable UI templates and components:
- Brand alignment: Allows businesses to integrate wallets with their overall brand identity through customizable colors, logos, and fonts.
- Tailored user journeys: Provides flexibility to design experiences that match the needs of different target audiences.
Wallet Types Offered by WaaS Providers
Wallet-as-a-Service platforms typically offer various Web3 wallet types to cater to different needs and use cases.
Custodial Wallets
In custodial wallets, a third party manages private keys, significantly simplifying the user experience. These are often used by centralized exchanges or applications where accessibility is the primary goal, such as loyalty programs.
Non-Custodial Wallets
Non-custodial wallets give users complete control over their funds and are typically used to access DeFi platforms, NFT marketplaces, and Web3 games. These prioritize user autonomy, privacy, and control over assets.
For decentralized applications, non-custodial wallets are generally preferred as they offer the most Web3 functionalities and align with the ethos of the decentralized ecosystem.
Advanced Wallet Technologies Used by WaaS Providers
Smart Wallets
Smart wallets are digital wallets managed by smart contracts following the ERC-4337 specification rather than being controlled solely by private keys. They offer enhanced security, recovery options, and programmable transactions.
Key benefits:
- Eliminate private keys and seed phrases, removing the risk of lost access due to forgotten credentials
- Enable social and multi-signature recovery options through trusted contacts
- Support programmable transactions through smart contract capabilities
- Allow gasless transactions where projects can sponsor fees on users' behalf

Embedded Wallets
Embedded wallets are built directly into applications, allowing users to manage assets and interact with blockchain without switching between apps.
Key benefits:
- Simplify user experience with familiar login methods across multiple devices
- Offer enhanced security features including multi-factor authentication
- Enable customized experiences that align with project aesthetics and functional needs
Multi-Signature Wallets
Multi-signature wallets enhance security by requiring multiple approvals to execute transactions, ensuring no single individual has unilateral control over assets.
Key benefits:
- Significantly reduce risks of theft and unauthorized access
- Provide flexible access control with customizable approval schemes
Multi-Party Computation Wallets
MPC wallets use cryptographic techniques to split private keys into multiple shares distributed among various parties, ensuring no single entity can access the complete key.
Key benefits:
- Provide advanced access control with granular permission settings
- Offer flexibility for complex transaction requirements
- Work across all EVM-compatible blockchains
The core difference between multi-signature and MPC wallets lies in how private keys are managed. Multi-signature wallets use multiple private keys for an account, while MPC wallets shard a single private key among different parties.
Streamlining Web3 Onboarding with Modern Tools
Modern connectivity solutions offer more than just Wallet-as-a-Service—they provide comprehensive toolkits that simplify the onboarding process for users and make blockchain applications accessible to everyone.
These platforms typically offer two main wallet types: in-app wallets and smart wallets. Both allow users to onboard with just an email, phone number, or social media account, significantly lowering the entry barrier. They also incorporate built-in payment solutions designed to facilitate onramping and bridging within applications.
Additionally, these solutions often include session authentication, permission management, and customizable administrative structures.
Smart Wallet Implementation
Modern account abstraction technology makes it easier to deploy smart cryptocurrency wallets with next-generation features. This approach enables seamless transactions by abstracting blockchain logins away from users, allowing them to interact with blockchain applications without understanding underlying technical complexities.
In-App Wallet Solutions
In-app wallets offer embedded Web3 wallet experiences with extensive customization options and powerful integration capabilities. These enterprise-grade solutions allow developers to tailor wallet experiences to fit specific application or game requirements and branding.
The Future of WaaS Solutions
By offering intuitive user interfaces, flexibility, and robust security, WaaS solutions pave the way for widespread adoption of decentralized applications. They position themselves as crucial components of technology stacks that ensure smooth and enjoyable user experiences.
As the technology evolves, we can expect continued innovation in wallet security, user experience, and integration capabilities.
