+
+```ts:
+import { getIconUri } from '@mvc-org/mvc-resources'
+
+const uri = getIconUri({
+  type: 'metaContract',
+  codehash: 'a2421f1e90c6048c36745edd44fad682e8644693',
+  genesis: '94c2ae3fdbf95a4fb0d788c818cf5fcc7a9aa66a', // genesis for usdt
+})
+
+console.log(uri)
+// https://unpkg.com/@mvc-org/mvc-resources/icons/meta-contract/usdt.jpg
+```
+
