If the automatic prompt fails, you can manually add the network to your wallet using the following details:

* **Network Name:** Hyperliquid
* **RPC URL:** `https://rpc.hyperliquid.xyz/evm/`
* **Chain ID:** 999
* **Currency Symbol:** HYPE

This indicates that the RPC provider is currently congested or experiencing issues.
