 account.altcoin.popup.blur.msg=If you want to trade BLUR on Bisq please be sure you understand and fulfill \
 the following requirements:\n\n\
-To send BLUR you must use the Blur Network CLI wallet (blur-wallet-cli). After sending a transfer payment, the\n\
-wallet displays a transaction hash (tx ID). You must save this information. You must also use the 'get_tx_key'\n\
-command to retrieve the transaction private key. In the event that arbitration is necessary, you must present\n\
-both the transaction ID and the transaction private key, along with the recipient's public address.  The arbitrator\n\
-will then verify the BLUR transfer using the Blur Transaction Viewer (https://blur.cash/#tx-viewer).\n\n\
-If you cannot provide the required data to the arbitrator, you will lose the dispute case.\n\
-The BLUR sender is responsible for the ability to verify BLUR transfers to the arbitrator in case of a dispute.\n\n\
-If you do not understand these requirements, seek help at the Blur Network Discord (https://discord.gg/5rwkU2g).
+To send BLUR you must use the Blur Network CLI or GUI Wallet. \n\n\
+If you are using the CLI wallet, a transaction hash (tx ID) will be displayed after a transfer is sent. You must save \
+this information. Immediately after sending the transfer, you must use the command 'get_tx_key' to retrieve the \
+transaction private key. If you fail to perform this step, you may not be able to retrieve the key later. \n\n\
+If you are using the Blur Network GUI Wallet, the transaction private key and transaction ID can be found conveniently \
+in the "History" tab.  Immediately after sending, locate the transaction of interest. Click the "?" symbol in the \
+lower-right corner of the box containing the transaction. You must save this information. \n\n\
+In the event that arbitration is necessary, you must present the following to an arbitrator: 1.) the transaction ID, \
+2.) the transaction private key, and 3.) the recipient's address.  The arbitrator will then verify the BLUR \
+transfer using the Blur Transaction Viewer (https://blur.cash/#tx-viewer).\n\n\
+If you cannot provide the required information to the arbitrator, you will lose the dispute. In all cases of dispute, the \
+BLUR sender bears 100% of the burden of responsiblity in verifying transactions to an arbitrator. \n\n\
+If you do not understand these requirements, do not trade on Bisq. First, seek help at the Blur Network Discord (https://discord.gg/dMWaqVW).
