Description

This PR addresses Issue #1937.

In the Manually downloading snapshots section, users are guided to download testnet snapshots but are not explicitly warned to use the --chain testnet flag when starting the node.

This omission frequently causes a genesis hash mismatch panic for new node operators who unknowingly run the node with the default Mainnet configuration against a Testnet snapshot.

Changes

  • Modified docs/pages/guide/node/rpc.mdx: Added a warning blockquote explaining the necessity of the --chain testnet flag when using testnet snapshots.
  • Added a usage example preventing the panic.

Related Issue

Fixes #1937
