Free Gnosis Pay for Zerion

With Gnosis Pay, you can pay with a Visa card directly from your self-custodial address — with no fees or hidden costs!

Now you can use Wallet Connect and sign transactions in Zerion’s build-in mobile browser. Basically, you can use Ledger just like an imported address — of course, while keeping your private keys on your Ledger device. 

Device Sync for iOS
-------------------

You can now sync your list of wallets, favorite tokens, and custom networks in your [Zerion Wallet](https://zerion.io/) across all your Apple devices. 

While this sync is securely done via iCloud, it is separate from the optional iCloud backup of your seed phrase. Instead, this sync is helpful for storing your watched wallets.

API Case Study: ShapeShift
--------------------------

[Zerion API](https://zerion.io/api?utm_source=paragraph&utm_medium=product_updates&utm_campaign=24may) powers over 200 web3 apps, including DeFi, wallets, and more. 

In our latest case study, we explored how [ShapeShift DAO uses Zerion API](https://zerion.io/blog/how-shapeshift-dao-uses-zerion-api/) to show available tokens to improve usability, retention, and in turn, revenue. 

New videos on YouTube 
----------------------

We’re posting more videos on our YouTube channel. This includes a series of [videos for crypto beginners](https://www.youtube.com/watch?v=wJ1v_Hsuj0s&list=PLJPTnrZVRfXJj23tWZ7acn46pLydWJbAm) as well as a playlist with videos about how you can [explore web3 on mobile with Zerion](https://www.youtube.com/watch?v=yXJbiEGOEk0&list=PLJPTnrZVRfXIhH-o-0CsektYB_9jeRiZ_).
