👇Let’s hear from a couple… 📈@arbitrum is ushering in the next generation of social apps

"We’re excited to work with Alchemy to help builders in the Arbitrum ecosystem onboard the next million users!"

With Account Kit we anticipate builders will create apps that can both scale and feel seamless to the end user, ushering in the next generation of social apps."

Today, we’re thrilled to introduce Rollups.

Scaling solutions like rollups are essential to Ethereum's success in the long run, and Alchemy provides the most-reliable, comprehensive Rollup platform for developers building at any scale.

Here’s why you should roll with us 😎 Alchemy Rollups is more than just a sequencer and a testnet.

In addition, devs get benefits that only we can offer:

✅ Trusted infra that powers billions of transactions

✅ An ‘everything platform’ with all the dev tools you need

✅ Instant distribution to millions of devs

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

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

1/ How does ERC-6900 work?

ERC-6900 is designed to achieve two technical objectives:

• Provide standards for designing plugins for smart contract accounts.
• Enable any smart account developer to easily integrate any standardized plugin in their app. 2/ Plugin designers following the standard can work with three standardized components:

1. Validation
2. Execution
3. Hooks

1/ What is this ERC-6900 that @VitalikButerin has been talking about lately?

Let's dive into Modular Smart Contract Accounts (MSCA), and unpack why this is the "iPhone" moment for Ethereum accounts... 2/ First, we need to know about @erc4337 Smart Accounts: the new paradigm of building user accounts from smart contracts, instead of requiring users to create an externally-owned address (EOA) to begin acting onchain.
