+### 6. `@web3auth/base` is deprecated — use `@web3auth/modal` instead
+
+In v9, imports were often split across `@web3auth/base`, `@web3auth/modal`, and other packages:
+
+```ts title="v9 - Before"
+import { Web3Auth } from "@web3auth/modal";
+import { WALLET_ADAPTERS, WEB3AUTH_NETWORK } from "@web3auth/base";
+```
+
+In v10, everything you need is available directly from `@web3auth/modal`. The `@web3auth/base` package is deprecated and should no longer be used:
+
+```ts title="v10 - After"
+import { Web3Auth, WALLET_CONNECTORS, WEB3AUTH_NETWORK, AUTH_CONNECTION } from "@web3auth/modal";
+```
+
+> ✅ Cleaner import structure — use `@web3auth/modal` for everything.
