+## React Server Components - Async Pattern

+**CRITICAL**: In Next.js 15, always await params directly in async server components:
+
+```typescript
+// ❌ WRONG - Don't use React.use() in async functions
+async function Page({ params }: Props) {
+  const { account } = use(params);
+}
+
+// ✅ CORRECT - await params directly in Next.js 15
+async function Page({ params }: Props) {
+  const { account } = await params; // ✅ Server component pattern
+}
