 ### 2. Run a local cosmos-sdk Simapp instance

-It's recommended that you make your simapp instance mimic the denomination of cosmoshub-4 (`uatom`). Put the local address of your node as the value for `NEXT_PUBLIC_NODE_ADDRESS` in your `.env.local` file.
+It's recommended that you make your simapp instance mimic the denomination of cosmoshub-4 (`uatom`). Put the local address of your node as the value for `NEXT_PUBLIC_NODE_ADDRESSES` in your `.env.local` file.

 A more in depth tutorial on this is coming soon :)
