# Changelog #3

Hey Beta testers!

Here we are with our **third platform update**. This update is centered on giving you **richer data for smart contracts** you are interacting with. Let's see all the changes.

Token Lists
-----------

Thanks to the [**Uniswap**](https://uniswap.org) project called [**Token Lists**](https://tokenlists.org/), we are building and maintaining a database of **trusted fungible tokens**. We aim to keep it **always updated** in order to help you **recognize legitimate tokens** from scams, fakes and duplicates.

Example of Icon for Tether USD

In this update **Lett3r** starts using the **Tokens Lists** to **send emails faster** and, as always, to **build trust**. Every time you **receive a transaction** that includes a **trusted token**, it will **include the token icon** to prove its **authenticity**.

Contracts Metadata
------------------

We started reading **contract-level metadata** on **ERC-721** and **ERC-1155** contracts. This is useful to get **more information** about **each collection** you interact with.

This **“de facto standard”** has been driven by [**OpenSea**](https://opensea.io). The **difference is huge**, especially for **ERC-1155** contracts.

Wrapped Tokens
--------------

Wrapped Tokens are **ERC-20** tokens that **represent** a **native token** or a **token from a different blockchain**. When used to wrap a native token, like **WETH for Ethers** and **WMATIC for Polygon Matic**, they can be **swapped** **with** the corresponding **native token** by **wrapping and unwrapping** it.

![Example of Wrap](https://storage.googleapis.com/papyrus_images/c2d115ebfcfb5bee1b6a9f4f80b027f413e45be5ec78d7f659a073001217d453.png)

Example of Wrap

From this update, so-called **Deposit** and **Withdrawal** events will be supported by **Lett3r**.

We are on BNB Smart Chain
-------------------------

We are thrilled to announce that **Lett3r** now supports [**BNB Smart Chain**](https://www.bnbchain.org/en/smartChain)! The full set of features available on [**Ethereum**](https://ethereum.org/) and [**Polygon**](https://polygon.technology/) is now fully functional on **BNB Smart Chain**. We have **begun rolling out** the first batch of **whitelisted wallets**, and **we will continue** to add new wallets **in the coming days**.

As part of this update, we are adding support for [**Space ID**](https://space.id/). From now on, **Lett3r** will **look up wallet addresses** even for **bnb** domains.

Improvements and Fixes
----------------------

This release also includes:

*   Refinements in e-mail layout
    
*   Minor bug fixes
