How to Choose a Wallet Provider: A Practical Guide for Fintechs and Web2 Companies

How to Choose a Wallet Provider

Wallet infrastructure is the beating heart of any crypto product. Whether you’re enabling stablecoin payments, offering DeFi yields, or embedding onchain identity, wallets determine the UX, security, and regulatory exposure of your entire stack. Choosing the right provider isn’t just a technical decision; it’s a strategic one.

But not all wallets are created equal.

Here’s a framework to help fintech and Web2 teams evaluate wallet providers based on your use case, user base, and product roadmap. We also highlight the key trade-offs, with a strong emphasis on both user and developer experience.

Understand Custodial vs. Non-Custodial Wallets

Wallets generally fall into two categories: custodial and non-custodial.

In a custodial wallet model, either your company or a third-party provider holds the user's funds and private keys. This setup feels like a traditional fintech experience, where users can log in, reset passwords, and send funds without managing private keys themselves. The main advantages of custodial wallets include greater compliance control and faster account recovery. However, custodial models require money transmitter licensing (such as MSB and MTLs) and asset ownership shifts away from the user to the custodian.

In contrast, non-custodial wallets allow users to hold their own private keys while the app simply facilitates blockchain interactions. Dynamic, for example, is a non-custodial embedded wallet provider that abstracts away the need for seed phrases. Non-custodial wallets offer benefits like reduced regulatory burden, increased user self-sovereignty, and lighter compliance overhead. The downsides include potential friction and key management challenges, though these can be significantly reduced with modern features like account abstraction.

Today, most fintech companies opt for embedded non-custodial wallets with enhanced abstractions to deliver a smooth and secure onboarding experience while minimizing complexity.

UX Plays an Important Role

The next step is to define the kind of user experience you want to deliver. You may want users to onboard via a magic link, without installing browser extensions or managing recovery phrases. You'll need the wallet to remain consistent across both web and mobile sessions. Chain abstraction can remove confusion and ensure users aren’t forced to choose between Ethereum, Solana, Base, or others. Your app can also sponsor gas fees to simplify the transaction process.

Each of these decisions impacts both the user experience and the complexity of your backend. As you map the user journey from first interaction to first transaction, identifying potential points of friction will help you narrow down the wallet providers that best fit your product. Dynamic supports all of these capabilities out of the box, making it easy to tailor the UX without compromising on flexibility or performance.

The Regulatory Impact of Your Wallet Architecture

Even if your company isn’t directly regulated, your wallet architecture still has major implications for compliance. Custodial setups typically require federal registration as a Money Services Business (MSB) with FinCEN, along with state-level Money Transmitter Licenses (MTLs). They also carry obligations around KYC/AML screening and raise important questions around data security and liability, especially when wallets are linked to fiat transactions.

If your wallet provider is custodial or facilitates fiat off-ramping, it’s important to understand their licensing and compliance posture. Ask which licenses they currently hold. Also clarify their legal entity structure and whether they maintain a dedicated compliance team.

In the case of non-custodial wallet providers like Dynamic, licensing is not required because users retain control of their own keys and assets. Instead, we partner with regulated providers for any off-ramping or fiat-related functionality. This ensures that every integration complies with strict KYC, AML, and data security standards while still preserving user autonomy.

Pay Attention to Developer Experience

The right wallet provider should accelerate your roadmap by removing friction from integration and maintenance. Your engineers shouldn’t have to waste time deciphering confusing documentation or navigating unstable APIs. A truly developer-friendly solution is easy to implement, intuitive to maintain, and built to support long-term scalability.

Look for wallet providers that offer:

• Well-documented and easy-to-use SDKs that abstract away complexity
• Wallet session management that works reliably at scale
• Built-in gas sponsorship and transaction batching to simplify user flows
• Well-supported frameworks such as React and React Native
• Multi-chain compatibility with leading networks such as Ethereum, Solana, Base, and more

The faster your team can integrate and test, the faster you can ship. Dynamic helps teams launch quickly, stay focused, and reduce time spent on backend complexity.
