Features that are important to think through during development

The feature set depends on the type of wallet (custodial or non-custodial) and the product scenarios. Below are the components that are usually built into the wallet architecture from the very beginning.

Sending / receiving funds

Core wallet operations: getting an address, sending funds, estimating fees, and tracking transaction status until final confirmation.

Swap

Built-in token exchange through an aggregator or DEX: route selection, preliminary rate and fee calculation, trade confirmation.

Price chart

Displaying asset prices and performance: charts, notifications, and simple analytics. Helps the user understand what is happening with their balance and the market.

Multichain solution

Multiple blockchain networks support: adding networks, handling fees, addresses, and transaction nonces. Start with the required feature set and expand further.

Support for any tokens

Display of tokens and stablecoins: balances, icons, allowlists, and protection against fake assets. A separate viewing mode can be added for NFTs.

API for crypto exchange integration

Integration with exchange APIs for market data, deposits, withdrawals, or trading (if needed). Configure API keys, access permissions, and secure limits.

Cross-platform / cross-browser

Unified UX across web and mobile: consistent flows, stable performance on different devices and browsers, data synchronization, and minimal fragmentation.

FAQ

What is the difference between a custodial and a non-custodial wallet?
In a custodial wallet, the service (provider/platform) manages the keys. In a non-custodial wallet, the keys are held by the user, and the service cannot recover access for them.
What to choose: custodial or non-custodial?
If you need account recovery, user support, and controlled operations, a custodial model is usually the best option. If you want full user control and dApp scenarios, go with a non-custodial one. In practice, the choice depends on product requirements and compliance.
Is it possible to enable login via email/socials without a seed phrase?
Yes. This is usually called embedded wallets : the wallet "lives" inside your application, and the user logs in using familiar methods (email/social). The keys can be managed using approaches like MPC/AA to remove the seed phrase from onboarding.
What is a smart-contract wallet and Account Abstraction (ERC-4337)?
Account Abstraction (ERC-4337) allows replacing standard EOAs with smart accounts controlled by smart contract logic. This enables features like gas fee sponsorship, multisig, social recovery, and transaction limits. This approach is the foundation of smart-contract wallets and provides a Web2-like UX in Web3 applications.
What is multisig and why does business need it?
Multisig is a wallet where multiple signatures are required to execute a transaction (for example, 2-of-3). It is commonly used for corporate funds, treasuries, funds management, and scenarios where control and separation of responsibility are important.
What are on-ramp and off-ramp, and can they be integrated into a wallet?
On-ramp/off-ramp are services that allow users to buy crypto with fiat and convert crypto back to fiat. They can be integrated into a wallet via providers, but requirements heavily depend on jurisdiction and compliance.
