Problem Statement

My project is a mobile app with cryptocurrency wallet functionality. It allows you to access the balance by mnemonic phrase and private key. Balance of both ERC20 tokens and ERC721 tokens with metadata is displayed. It is possible to send the necessary token to the specified address.

Solution

Logging into the app, or creating a new wallet, is done using the Web3Swift library, which provides access to an Ethereum account. The project uses Covalenthq as an API to retrieve balance data, metadata for ERC721 tokens, and all necessary data to send tokens. The tokens and NFT for testing are Polygon.
