 One interesting thing you can do with Stellar is issue your own custom "currency". Here's a simple example of doing so. This route involves making an offer on the distributed exchange, and then waiting for someone to make an overlapping counteroffer.

+One interesting thing you can do with Stellar is issue your own custom "currency". Here's a simple example of doing so. This route involves making an offer on the distributed exchange, and then waiting for someone to make an overlapping counteroffer.
+
+I've created an offer giving 30 minutes of my help (represented by the currency `GDB`) on a project of your choice [1], in exchange for 1,000 stellar. You can see this offer in the graphical account viewer: https://www.stellar.org/viewer/#/gdb (for the moment, you have to click the "Live" button manually).
+
+# Did you just claim the currency `GDB`?!
+
+Not quite. Stellar works a bit off the principle "Is the blue you see, the same blue I see?" If someone trusts a bunch of gateways for USD, if effectively means that they personally consider those issuers' USD all interchangeable. Another person might only want one of those gateways' USD, in which case they don't need to trust the other gateways. Another might have a completely separate concept of what "USD" means, and trust none of those gateways, but be none-the-worse for it.
+
+So really I've just claimed the currency GDB for people who choose to trust me directly.
+
+# Seeing the offer in the API
+
+My Stellar account is `gpFfX9931eSbjUhtu3ujb6Tu7Z48u53uiL`. First, you can check the status of my offer like so:
+
+```
+$ curl -X POST https://live.stellar.org:9002 -d '{"method":"account_offers", "params": [{"account": "gpFfX9931eSbjUhtu3ujb6Tu7Z48u53uiL"}]}'

+      "account" : "gpFfX9931eSbjUhtu3ujb6Tu7Z48u53uiL",
+      "offers" : [
+         {
+            "flags" : 0,
+            "seq" : 14,
+            "taker_gets" : {

+               "issuer" : "gpFfX9931eSbjUhtu3ujb6Tu7Z48u53uiL",
+               "value" : "30"
+            },

+         }
+      ],
+      "status" : "success"
+   }
+}
+```
+
+This represents an offer for 30 GDBs, issued by my account, in exchange for 1,000,000,000 microstellar.
+
+# Executing the trade
+
+You can execute the trade by making your own matching counteroffer. (Note you have to fill in your account credentials to the command below, which you can find in the Stellar client — the account ID is shown under the "Receive" -> "Show your Stellar Address", while the secret is shown in the settings window.)
+
+```
+$ curl -X POST https://live.stellar.org:9002  -d '

+        {

+            }
+        }
+    ]
+}'
+```
+
+# Checking that it worked
+
+You can check the updated balance in your account with the `account_lines` API call:
+
+```
+$ curl -X POST https://live.stellar.org:9002 -d '{"method":"account_lines", "params": [{"account": "gpFfX9931eSbjUhtu3ujb6Tu7Z48u53uiL"}]}'
