**Short description:** Development of an open-source web API system to ‘bridge’ enterprise IT and the Polkadot blockchain ecosystem.

Please note this motion is a batch call, rejecting [treasury proposal no. 247](https://polkadot.polkassembly.io/treasury/247) and [treasury proposal no. 248](https://polkadot.polkassembly.io/treasury/248) and approving [treasury proposal no. 251](https://polkadot.polkassembly.io/treasury/251): while submitting, the Aventus team made mistakes on submissions regarding the amounts for the first two proposals, and they need to be rejected. 

Contextual information for the treasury proposal to be reviewed and vote can be found [HERE](https://polkadot.polkassembly.io/treasury/251). 

Discussion post can be found [HERE](https://polkadot.polkassembly.io/post/1647). 

Send a batch of dispatch calls.

May be called from any origin except `None`.

- `calls`: The calls to be dispatched from the same origin. The number of call must not
  exceed the constant: `batched_calls_limit` (available in constant metadata).

If origin is root then the calls are dispatched without checking origin filter. (This
includes bypassing `frame_system::Config::BaseCallFilter`).

# <weight>
- Complexity: O(C) where C is the number of calls to be batched.
# </weight>

This will return `Ok` in all circumstances. To determine the success of the batch, an
event is deposited. If a call failed and the batch was interrupted, then the
`BatchInterrupted` event is deposited, along with the number of successful calls made
and the error of the failed call. If all were successful, then the `BatchCompleted`
event is deposited.
