The new internet is onchain and social.

Get a first look at the feed inside the new Coinbase Wallet beta.

I love the self owned social accounts and messaging with @farcaster and @xmtp in @coinbasewallet! 
 
Now we just need a secure way to verify and sign @safe transactions txs. Unfortunately the "Message data" field in the mobile app isn't possible to be used in tools like @openzeppelin's Safe Utils to confirm the tx hashes because the data can't be copy and pasted.

For @safe multi factor verification MFV generating the transaction tx hashes with @openzeppelin Safe Utils on both the device|UI where the tx is created and on separate devices|UIs signing the tx is essential.

This way the tx hashes created between devices|UIs can be compared. Otherwise using Safe Utils with data from only 1 source would not detect if that source is showing bad info while displaying a correct tx hash.

E.g.
1. Create tx on 1st device with Safe UI
2. Create tx hashes with Safe Utils and Safe UI data
3. Sign on 2nd device with software account, E.g. @metamask
4. Create tx hashes with Safe Utils and MetaMask data
5. Compare tx hashes created from both Safe UI and MetaMask to make sure they're the same

Thank you to @so for talking through different tx signing scenarios!
