## Content

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 ListsThanks to the Uniswap project called Token Lists, 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 USDIn 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 MetadataWe 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.SFT Approved before and after the updateThis “de facto standard” has been driven by OpenSea. The difference is huge, especially for ERC-1155 contracts.Wrapped TokensWrapped 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 WrapFrom this update, so-called Deposit and Withdrawal events will be supported by Lett3r.We are on BNB Smart ChainWe are thrilled to announce that Lett3r now supports BNB Smart Chain! The full set of features available on Ethereum and Polygon 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. From now on, Lett3r will look up wallet addresses even for bnb domains.Improvements and FixesThis release also includes:Refinements in e-mail layoutMinor bug fixesFeedbackThank you for your feedback!
