getFees

Deprecated: This method is deprecated. Use getFeeForMessage and getLatestBlockhash instead.

Returns a recent block hash from the ledger, a fee schedule that can be used to compute the cost of submitting a transaction, and the last slot in which the blockhash will be valid. This method has been deprecated in favor of the combination of getLatestBlockhash and getFeeForMessage, which provide a cleaner separation of concerns and support for the newer fee model.
