How To Set Up A Secure Digital Wallet

One question is how to create a digital wallet. The second important question is to ensure your digital wallet is secure. You must protect your users from fraud and hackers. Here are some tips for setting up a secure digital wallet.

Use Encryption

The bare minimum is encrypting data in transit with HTTPS and encrypting stored data at rest. Consider adding an extra layer of security with end-to-end encryption. Encryption scrambles data so it looks like gibberish to anyone unauthorized. Make sure to encrypt users' private keys, personal info, and transaction data. Use strong, up-to-date encryption algorithms in e-wallet app development. Implement Point-to-Point Encryption (P2PE) for secure transactions.

Install Multi-Factor Authentication

Don't rely on a password alone. Require extra authentication steps like a fingerprint scan or a code from the user's mobile device. This stops unwanted access even in the case that passwords are stolen.

Use A Firewall

Implement a firewall to track and control incoming and outgoing network traffic. This prevents unauthorized access to the wallet from external networks.

Set Transaction Limits

Set limits on transaction amounts and frequencies. This reduces the impact of security breaches. This also limits potential loss if the wallet is compromised.

Follow Best Coding Practices

Write secure code. Sanitize inputs. Guard against common vulnerabilities like SQL injection and cross-site scripting. Rigorously test for security holes.

Enable Remote Device Wiping

Let users remotely wipe their wallet data from lost/stolen devices. This prevents crypto theft if a device gets misplaced.

Rigorous Testing

Conduct thorough security testing before each release. This includes static code analysis, penetration testing, fuzzing and audits. Identify and fix vulnerabilities proactively.

Keep Software Updated

Update the wallet app on a regular basis with the latest security patches. Out-of-date software is an open door for hackers. Security is an endless journey, not a final destination. Prioritizing these measures builds trust that your digital wallet safeguards user funds.

Our Experience

SDK for a crypto wallet

Stfalcon has developed an SDK for a crypto wallet based on Kotlin Multiplatform. The development team used the latter because one task was to combine business logic and use the same code base on different platforms.

We developed interfaces able to interact with UI apps, their implementation will rigidly define states, the format of data acquisition, and errors.

The most important development flow was the architecture for the SDK development. We used Clear Architecture with Interactors. We also separated the platform-dependent code into a separate submodule with external implementation directly on the platforms. SDK integration with the platforms was, by the way, the most difficult step.
