# V 1.3.0 (Multi-Coin)

Multi-coin firmware V1.3.0 includes the following changes and updates:

1\. The watch-only wallet has been renamed from "Keystone Ethereum Extension" to "Web3" and will be integrated  with other Web3 wallets and DeFi projects through [Onboard.js](https://github.com/blocknative/onboard) at a later date.

2\. In the Web3 mode, we have upgraded the QR code encoding/decoding to a new format. **This is an incompatible change and you need to upgrade your Keystone Ethereum** [**Chrome**](https://chrome.google.com/webstore/detail/keystone-ethereum-extensi/obefccfphekeeeojgpicpeafipdlohig?hl=en-US\&authuser=1) **Extension accordingly to the latest version.**

3\. In the Web3 mode, we have optimized the function of “decoding DeFi transactions”.

* The ABI file data structure is optimized so downloading it now to a microSD card only requires \~30 seconds compared to \~30 minutes in the previous version. **Please note that the previous ABI package no longer works so you will need to re-download the package after this firmware upgrade. Please check the tutorial and ABI package download link** [**here**](https://support.keyst.one/advanced-features/decode-defi-transactions)**.** 
* Supports decoding tuple type transactions.

4\. The Keystone Ethereum [Chrome](https://chrome.google.com/webstore/detail/keystone-ethereum-extensi/obefccfphekeeeojgpicpeafipdlohig?hl=en-US\&authuser=1) Extension is also updated with a new QR code encoding/decoding method and it now supports EIP 191 personal\_sign message.
