Do I need to update my Kaspa wallet for the Toccata fee change?

If your wallet uses the RPC fee estimation API — which most wallets do — you do not need to change anything. The RPC fee estimation API is a built-in network service that wallets query to automatically calculate the correct fee before sending a transaction. When Toccata activates and the minimum rate rises, the API returns the new higher value and your wallet uses it without any manual step. Only developers or users running custom software that calculates fees independently, rather than querying the API, will need to update their code. If you are unsure whether your setup qualifies, consult your wallet's documentation — standard consumer wallets are almost certainly covered.
