title: What is the Solidity interface for the RSK Bridge smart contract?
body: <p>The RSK Bridge exposes its interface through a smart contract deployed at <a href="https://explorer.rsk.co/address/0x0000000000000000000000000000000001000006" rel="noreferrer"><code>0x1000006</code></a>. I was able to find <a href="https://github.com/rsksmart/precompiled-abis/blob/master/abis/bridge.json" rel="noreferrer">the ABI file for the Bridge</a> on github.</p>
  <p>I'm after a Solidity interface file instead - is there one available, and if so where can I find it?</p>
