Batch calls

Batch calls allow a single call to the World to perform multiple System calls. Using batchCall (opens in a new tab) you can issue calls on your own behalf. If you have the proper delegations, you can also use batchCallFrom (opens in a new tab) to issue System calls on behalf of other addresses.

The calls take place sequentially, and after they all finish successfully you get back the return values from all of them. If any of the calls revert, so does batchCall / batchCallFrom, so all the state changes created by the previous calls are discarded.
