# EPF5 Week 0 Updates I want to integrate the Portal Network client [trin](https://github.com/ethereum/trin) into an Android app ([Android Portal](https://github.com/biafra23/AndroidPortal)) to use it to implement wallet functionality without using a centralized RPC service. - Listing tx history per wallet address from the Portal network - Creating a transfer tx for Ether, ERC-20 tokens and ERC-721 NFTs (locally, needs some data from Portal network. i.e. current nonce) - Signing the tx (locally) - Submitting the tx via the Portal Network Some of the necessary features are not yet available in the Portal network. For exampel submitting a signed tx.
