Where can I find an example of a sponsored transaction (ERC-4337)?

Question

I know this is the standard repo but I am not finding an actual example on how I can send a transaction from an account, paying for gas fees in an ERC20 token (paymaster providing ETH once tokens are transferred to it).

Answer 1

Stackup has an example of an ERC-4337 transaction, including paymasters: https://docs.stackup.sh/docs/guides/quickstart

There is also a Tutorial from zkSync here.
