Closes: #11415 ## Description - Create `FeeMarket` interface, and move exiting static fee logic into `StaticFeeMarket` implementation. - Merged `MempoolFeeMiddleware` and `TxPriorityMiddleware` into `DeductFeeMiddleware`, so we can deduct fee based on the check result. - ~~Support extension options in `Tx.AuthInfo`, so feemarket module can extend the tx fields.~~ Keep in TxBody - No Ledger support in v0.46 --- ### Author Checklist *All items are required.
