4337 Tools

What is ERC-4337?
​ERC-4337 is a new standard proposed by the community that allows for account abstraction without any protocol changes. It promises a whole new, easier way to interact with the Ethereum ecosystem. Losing your private keys will not necessarily mean permanent loss anymore; you won’t need ETH to pay your gas fees; and the off-chain world becomes increasingly simpler to integrate into your on-chain activity.

Our tools allow you to transmit, monitor, and visualize ERC-4337 userOperations:
Use the Blocknative 4337 bundler to get your userOperations on chain
Visualize userOperations moving through the mempool with the 4337 UserOps Explorer​
Monitor for pending and confirmed bundler transactions going through the EntryPoint contract using Mempool Explorer​
If you have any questions join the #ERC-4337 channel on discord.
