-You can use the demo wallet to test Hosted Deposit and Withdrawal (SEP-24) and Cross-Border Payments (SEP-31) with any home domain that has a Stellar Info File (also known as SEP-1, or a stellar.toml file). The instructions below are for demo-ing standard integrations supported by Stellar test server, testanchor.stellar.org. For both integrations, the logs to the right of the screen will show every network call.

+1. Click "Generate keypair", and then click "Create account" - this will create a balance of 10,000 XLM.
+2. Click “Add asset” and add `MYASSET` with the anchor home domain `sep8-server.dev.stellar.org`.
+3. Click “Add trustline” - this will allow you to hold MYASSET.
+4. Click on the "Copy" link on the right of your public key and use that value to get some unities of MYASSET using the link `https://sep8-server.dev.stellar.org/friendbot?addr=<paste_your_address_here>`.
+5. Select "SEP-8 Send" from the dropdown of MYASSET and click "Start" in the modal.
+6. In the "destination" field, input an address that also has a trustline to MYASSET.
+7. The modal will display the approval criteria used by the SEP-8 server. Depending on the conditions described there your payment can be automatically approved or you may be required to undergo an additional KYC step.
+8. After your payment gets revised and signed by the SEP-8 reference server you'll need to review the updated transaction before the demo wallet submits the payment.
+9. If the payment has been successfully sent you'll see "SEP-8 send payment completed 🎉" in the logs.
