** re: Finder&rsquo;s Fee: this payment is set aside to incentivize a broad search for the right implementor. Finder&rsquo;s Fees are paid out at time of team engagement. Teams that submit themselves can collect their own Finder&rsquo;s Fee at completion of project.

Send a batch of dispatch calls and atomically execute them.
The whole transaction will rollback and fail if any of the calls failed.

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`).

## Complexity
- O(C) where C is the number of calls to be batched.

- **Problem Statement:** Refining a treasury proposal into an RFP for smart contract development on Kusama Hub with a prize pool of $43,000.
- **Significance:** Enhancing oversight and scope for the project with a clear timeline and deliverables.
- **Proposed Solution:** Developing a Solidity-based smart contract with ZK capabilities, a user-friendly interface, and anti-correlation attack mitigations.
- **Expected Outcomes:** Transparent project updates, open-source code delivery, and successful deployment on Kusama Hub by July 31.
