Step 5: Develop Transaction HandlingBuild modules for processing transactions, including initiation, signing, and broadcasting to the blockchain network. Implement transaction fee handling and support for multiple transaction types.

Step 6: Implement Security FeaturesPrioritize security by implementing measures such as two-factor authentication, encryption, and access control. Regularly update your wallet to address security vulnerabilities.

Step 7: Test and DeployThoroughly test your wallet's functionality, security, and usability. Deploy your wallet to a stable environment, such as a cloud server or mobile app store.

ConclusionBuilding a cryptocurrency wallet requires careful planning, implementation, and ongoing maintenance. By following this guide, you can create a secure and user-friendly wallet that meets the evolving needs of the digital asset industry.
