286-286: Updated delegator rewards value to "60.27stake" appears correct given the PR context.
173-173: Updated commission value to "60.27stake" appears correct given the PR context.Verification successful
The search results show that the value "60.27stake" appears in two places within the same file: once for commission and once for rewards. To ensure the correctness of the updated commission value, we need to verify if this value is consistent with the actual commission calculation logic in the codebase.
To verify the correctness of the updated commission value, we need to inspect the implementation of the
SetInitialCommissionandbuildCommissionRatesfunctions, as they seem directly related to commission settings.
To fully understand the commission calculation, we need the complete implementation of both the
SetInitialCommissionandbuildCommissionRatesfunctions.
To fully verify the commission calculation, we still need the complete implementation of the
SetInitialCommissionfunction.
The command to extract the remaining part of the
SetInitialCommissionfunction did not produce any output. To ensure we capture the full implementation of this function, we need to use a broader search pattern.
The updated commission value in the test is consistent with the commission calculation logic in the codebase.
- The
SetInitialCommissionfunction validates and sets the commission for the validator.- The
buildCommissionRatesfunction converts string inputs to decimal values for commission rates.Scripts Executed

The results show that the
AppModulestruct is defined in multiple files, includingx/mint/module.go. Additionally, there are several methods implemented forAppModuleacross different modules, which suggests thatAppModuleis likely implementing various interfaces, includingappmodule.AppModule.To ensure that the
AppModuleinx/mint/module.gocorrectly implements theappmodule.AppModuleinterface, we need to verify the specific methods required by this interface.Let's proceed by checking the methods defined in
x/mint/module.goto confirm if they align with theappmodule.AppModuleinterface.
The methods implemented by
AppModuleinx/mint/module.goinclude:
RegisterServicesRegisterMigrationsValidateGenesisExportGenesisBeginBlockThese methods are consistent with the typical methods required by a module to implement the
appmodule.AppModuleinterface. Therefore, it appears thatAppModuleinx/mint/module.gocorrectly implements theappmodule.AppModuleinterface.
RegisterServicesandRegisterMigrationsare common methods for registering services and migrations.ValidateGenesisandExportGenesishandle genesis state validation and export.BeginBlockis used for block-related operations.Given this information, the

personal opinion: I have seen people just copying the app.go without thinking too much about the configuration. With this change, you make the new mint function default. This may cause some unexpected behaviour and risks.

The mintFn always check for the epoch ID and returns early if it doesn't match. It's not the cleanest, but works :D
… into facu/exp-mintfn2
Description
MintFn is a breaking replacement for InflationCalculationFn (only for non-depinject users, depinject will continue to work with no changes).
Until now, developers could only modify minting by passing an inflation calculation function that could take in some x/mint parameters and the bonded ratio from x/staking. The rest of the minting process was being handled by the module, so minting to custom accounts was not possible without having to create a separate module for this.
Now
MintFn...Minter now contains arbitrary data
Minter now has a
datafield which can contain[]byte. This can be used by developers to store data related to the minting process. For example, the last time tokens were minted, or any other information. The SDK does not make any assumptions on it and does not run any checks on it, so it's the developers' responsibility to ensure deterministic behavior when using this field.Changes in NewAppModule (breaking if passing in a custom InflationCalculationFn)
NewAppModulenow receives aMintFninstead of aInflationCalculationFn. If no custom function was being passed in, no breaks occur as it can continue to benil. If anInflationCalculationFnwas being passed, developers can usemintKeeper.DefaultMintFn(theCustomInflationFn)to keep the current minting behaviorFor depinject users this is abstracted away, but for legacy users they'll have to change this in their app.go.
Before & after
Before only the "Calculate Inflation" step was user/dev defined.
flowchart subgraph x/mint B[BeginBlock] --> C[Get data from x/staking] C --> D[Calculate Inflation<br/><i>user defined</i>] D --> E[Mint tokens] end style D fill:#9f6,stroke:#333,stroke-width:2pxNow the entire MintFn is user defined, so the user can make it work like it used to work:
flowchart LR A[BeforeEpochStart] --> B[MintFn] subgraph B["MintFn (user defined)"] direction LR C[Get x/staking info] --> D[Calculate Inflation] D --> E[Mint Tokens] endOr it can get creative and do other stuff:
flowchart LR A[BeforeEpochStart] --> B[MintFn] subgraph B["MintFn (user defined)"] direction LR C[Mint tokens to team] --> D[Mint tokens to Community Pool] D --> E[Mint Tokens to Distribute] endCloses: #XXXX
