Summary:
This update introduces significant enhancements to our decentralized wallet, including the integration of a Swap feature alongside an improved crypto-to-fiat conversion functionality. Leveraging Ref Finance for swap capabilities and NEAR Protocol's Easy Onboarding for streamlined user adoption, users can now seamlessly exchange assets within the wallet environment and convert cryptocurrencies to local fiat currency. The primary focus is on enhancing user experience, expanding utility, and ensuring secure, decentralized transactions.

Change and Issue Fixed:
The key change involves the integration of a Swap feature within the decentralized wallet, addressing the need for efficient asset exchange directly within the wallet interface.

Motivation and Context:
The motivation behind these enhancements is to provide users with a comprehensive decentralized wallet solution that offers both convenience and accessibility. With the increasing adoption of cryptocurrencies, enabling crypto-to-fiat conversion directly within the wallet aligns with market trends and user expectations. Moreover, by leveraging NEAR Protocol's Easy Onboarding, the update simplifies the user adoption process by covering the setup costs and providing users with personalized wallet names, enhancing user onboarding and retention.
