Project description:
"I am looking to hire an experienced Blockchain / Web3 / Mobile App Developer (or a team) to build an advanced crypto gift wallet, similar to Trust Wallet, but with additional automated features and a modern, high-security architecture.

The wallet will allow users to store crypto, send/receive assets, create “gift wallets,” and earn automatic monthly interest on their holdings. The system must be clean, secure, fast, and coded using industry best practices.
