@@ -72,7 +72,7 @@ MetaMask behavior to keep in mind:
 
 - MetaMask primarily depends on JSON-RPC correctness, not explorer richness.
 - `wallet_addEthereumChain` and `wallet_watchAsset` help wallet UX, but they do not replace missing RPC methods.
-- If `eth_maxPriorityFeePerGas` is unavailable, MetaMask can still work, but fee UX may be less polished than on top-tier public networks.
+- `eth_maxPriorityFeePerGas` is now available on the public RPC, so fee UX should align better with mainstream EVM wallet expectations.
