* MAY revert all calls if any call fails

### `atomicBatch` Capability

Like the illustrative examples given above and other capabilities to be defined in future EIPs, the capability to execute calls delivered via the above-defined methods in a single transaction can be attested by the wallet in boolean form.
This capability is expressed separately on each chain and should be interpreted as a guarantee only for batches of transactions on that chain; batches including calls to multiple chains is out of scope of this capability and this specification.

If a wallet has affirmatively expressed this `atomicBatch` capability to a calling application, it MUST submit calls submitted with `wallet_sendCalls` as part of a single transaction.
