MetaMask error switching ETH → PLS: likely custom RPC or token mismatch

I see you get an error when switching from ETH to PLS in MetaMask. That usually indicates a network or token mismatch rather than a wallet bug.

Common causes are a missing or incorrect Pulse (PLS) custom RPC/chain ID, attempting to use an ERC‑20 token address on the wrong network, or insufficient gas funds on the target chain. MetaMask will block the switch or show errors when those conditions exist.

I recommend verifying the PLS network settings (RPC URL, Chain ID, currency symbol), confirming the token contract is deployed on Pulse and not Ethereum, and ensuring you have a small balance of the native token for gas. If problems persist, update MetaMask, clear pending transactions, or re-add the network manually.
