# Class BSV::Network::Protocols::Arcade <a id="class-BSV-Network-Protocols-Arcade"></a>

**Inherits:** `BSV::Network::Protocol`

Arcade protocol implementation for submitting transactions to the BSV network.

Arcade is a sibling to ARC — both subclass Protocol directly. The request and
response shapes diverge enough to rule out a shared abstract base: Arcade uses
a narrower status taxonomy and a different broadcast response structure (no
txid on fresh submission; idempotent re-submit returns status plus txid plus
state).

## Example

    arcade = BSV::Network::Protocols::Arcade.new(
      base_url: 'https://arcade.gorillapool.io'
    )
    result = arcade.call(:broadcast, tx)
    result.http_success? # => true
    result.data['status'] # => "submitted"

## Constants
### `REJECTED_STATUSES` <a id="constant-REJECTED_STATUSES"></a> <a id="REJECTED_STATUSES-constant"></a>
Arcade response statuses that indicate a transaction was NOT accepted.
Narrower than ARC's taxonomy — Arcade has a single explicit rejection signal.
