A few weeks ago @yoavw proposed a new API to help layer 2 blockchains attract ERC-4337 bundlers.
Here's how it works 👇

First the official link:

Bundlers need some assurance that the network state will not change on a layer 2 blockchain between the time a bundler does its checks and the transaction is included.
This would lose bundlers money.

Bundlers need some assurance that the network state will not change on a layer 2 blockchain between the time a bundler does its checks and the transaction is included.
This would lose bundlers money.
To fix this, Yoav proposes a new RPC request.
The request is eth_sendRawTransactionConditional, which acts just like eth_sendRawTransaction but includes some lightweight checks for the sequencer so the bundler doesn't submit an invalid bundle.

It checks:
- block number is within a range
- block time is within a range
- validate that a list of addresses haven't changed state OR
- that storage slots of addresses have the expected values

This won't stop us from deploying on new networks of course.
But if it becomes unprofitable to run bundlers on these networks, everyone loses.
