Today, we’re adding the "aa-signers" SDK to Account Kit 💼

With this new package, integrating smart accounts in your app has never been easier👇

🔗🛠️ accountkit.alchemy.com/packages/aa-si…
Signers enable you to secure your accounts with measures like email and social login, passkeys, or a self-custodial wallet.

Until today, if you utilized Account Kit, it was up to you to specify how you wanted to implement signers within your application. 🤔

Community Subgraphs are here!

Query data from commonly used subgraphs or popular protocols

All without ever having to create your own Subgraph

Your ticket to instant, simplified data access 2/
Often, you may want to access subgraph data that’s not your own

Maybe to index another DeFi protocol’s data

Or to access specific block-level data

Until today, you would have had to index this data yourself

ERC-6900 is designed to achieve two technical objectives:

• Provide standards for designing plugins for smart contract accounts.

1. Validation
2. Execution
3. Hooks
