+## Abstract
+
+Currently, `GasPerBlobByte` and `TxSizeCostPerByte` are defined as module parameters within their respective modules, `blob` and `auth`, allowing for their modification via a `ParameterChangeProposal` in the Cosmos SDK.
+
+The proposed solution is to transition these parameters to hardcoded values within the application that can be accessed with a gatter throughout the application.
+
+## Motivation
+
+Versioning on-chain governance modifiable parameters, such as `blob.GasPerBlobByte` and `auth.TxSizeCostPerByte`, aims to stabilize gas estimation by removing block-to-block variability.
+
+## Specification
+
+Currently, `GasPerBlobByte` and `TxSizeCostPerByte` are module parameters within the `blob` and `auth` modules, allowing for their modification via ParameterChangeProposal. The proposed modification changes these parameters to hardcoded constants within the application, accessible via version-specific getters.
+
+### Parameters
+
+The proposal makes these two variables modifiable through hard fork upgrades:
+
+Previously:
+
+1. `blob.GasPerBlobByte`
+2. `auth.TxSizeCostPerByte`
+
+Now:
+
+1. `appconsts.GasPerBlobByte`
+1. `appconsts.TxSizeCostPerByte`
+
+### Rationale
+
+Versioned Gas Scheduler Variables allow for hardcoding these values into estimators, simplifying the gas estimation process and making transaction costs more predictable without the need for pre-transaction queries.
+
+## Backwards Compatibility
+
+Enabling this feature requires a hard fork network upgrade.
+
+## Test Cases
+
+Test cases should verify that gas scheduler variables are exclusively updated via hard fork, effectively preventing updates through governance mechanisms.
+
+## Reference Implementation
+
+TBC
+
+## Security Considerations
+
+This change prioritizes network stability and predictability but requires heightened vigilance against potential misconfigurations.
