## Description We decided to remove middlewares, and revert to antehandlers (exactly like in v045) for this release. A better middleware solution will be implemented after v046. ref: https://github.com/cosmos/cosmos-sdk/issues/11955 This PR is part 2 of 2: - part 1: Revert baseapp and middlewares to v0.45.4 - part 2: Add posthandler, tips, priority Depends on: - [x] #11979 --- Suggestion for reviewers: - Apart from correctness, I would also like someone to review **exhaustiveness**. I.e. all changes we made in v046 into the [middleware folder](https://github.com/cosmos/cosmos-sdk/tree/v0.46.0-beta2/x/auth/middleware) are reflected in this PR, and that I didn't forget anything. I found the following ones: - add a TxFeeChecker in DeductFee - add a ExtensionChecker in ExtCheckerDecorator - add a TipDecorator --- ### Author Checklist *All items are required.
