 ## Onchain interactions via UserOperations
 
-The ERC-4337 standard revolves around UserOperations, which are basically objects replacing transactions and that are sent on behalf of the user by nodes known as [`Bundlers`](https://docs.stackup.sh/docs/erc-4337-bundler#:~:text=In%20ERC%2D4337%2C%20a%20Bundler,work%20on%20any%20EVM%20network.). UserOperations are signed by the user with their passkey and the bundler's job is to include them in a block while taking a little fee for the work. In our case, we use the [StackUp Bundler node implementation](https://docs.stackup.sh/). We strongly advise you to look at Stackup documentation and the ERC-4337 EIP to understand how Bundlers work.
