* Creates a trade-bot entry from the 'Alice' viewpoint, i.e. matching ARRR to an existing offer.

* <p>
* The <tt>crossChainTradeData</tt> contains the current trade offer state
* as extracted from the AT's data segment.
* <p>
* Access to a funded wallet is via a PirateChain BIP32 hierarchical deterministic key,
* passed via <tt>xprv58</tt>.
* <b>This key will be stored in your node's database</b>
* to allow trade-bot to create/fund the necessary P2SH transactions!
* However, due to the nature of BIP32 keys, it is possible to give the trade-bot
* only a subset of wallet access (see BIP32 for more details).
* <p>
* As an example, the xprv58 can be extract from a <i>legacy, password-less</i>
* Electrum wallet by going to the console tab and entering:<br>
* <tt>wallet.keystore.xprv</tt><br>
* which should result in a base58 string starting with either 'xprv' (for PirateChain main-net)
* or 'tprv' for (PirateChain test-net).
* <p>
* It is envisaged that the value in <tt>xprv58</tt> will actually come from a Qortal-UI-managed wallet.
* <p>
* If sufficient funds are available, <b>this method will actually fund the P2SH-A</b>
* with the PirateChain amount expected by 'Bob'.
* <p>
* If the PirateChain transaction is successfully broadcast to the network then
* we also send a MESSAGE to Bob's trade-bot to let them know.
