Based on the search results, I can now generate the final response since I have clear evidence of how IBC-related migrations are handled in the codebase.
The upgrade handler needs to be updated to enable Wasm client type in IBC params
Looking at the v2_1_0 upgrade handler, which is specifically focused on Wasm light clients, it performs necessary IBC-specific migrations by updating the allowed client types. Your handler should follow the same pattern:
params := clientKeeper.GetParams(ctx) params.AllowedClients = append(params.AllowedClients, ibcwasmtypes.Wasm) clientKeeper.SetParams(ctx, params)This ensures that the Wasm client type is properly registered with IBC after the upgrade.
🔗 Analysis chain
Line range hint
17-21: Verify the upgrade handler's minimal implementation.While the upgrade handler has been modified to accept the
clientKeeperparameter, it's not utilizing it for any IBC-specific migrations. Given that this PR is specifically about enabling Wasm light clients on IBC:
- The handler might need to perform IBC-specific migrations or validations
- Consider if any Wasm-related state migrations are required
Let's check if other upgrade handlers in the codebase perform IBC-specific migrations:
Consider whether you need to:
- Initialize any Wasm-specific state
- Migrate existing light client data
- Set up default parameters for the Wasm light client module
Would you like assistance in implementing these potential requirements?

Based on the search results, I can now generate the final response as we have clear evidence of how Wasm-related migrations are handled in the codebase, particularly from the v2_1_0 upgrade handler.
Wasm client type needs to be added to allowed clients list during upgrade
The upgrade handler should update the IBC client parameters to include the Wasm client type, similar to how it's done in v2_1_0:
params := clientKeeper.GetParams(ctx) params.AllowedClients = append(params.AllowedClients, ibcwasmtypes.Wasm) clientKeeper.SetParams(ctx, params)This ensures that Wasm light clients can be created after the upgrade.

136-140: Verify security implications of enabling Wasm clients.
While the implementation correctly adds Wasm to the allowed clients list, this is a significant security change that requires careful consideration:
- Enabling Wasm clients allows arbitrary light client implementations to be deployed.
- This change only affects newly initialized chains.
Let's verify the upgrade handling for existing chains:
Consider adding:
- Documentation comments explaining the security implications
- Validation of Wasm client configurations during runtime
- Explicit error handling for IBC state modifications

17-17: LGTM: IBC-Go version update
The update to github.com/cosmos/ibc-go/v7 v7.4.0 aligns with the PR objective of enabling Wasm light clients.
60-60: Verify compatibility with development version of Wasm light client module
The Wasm light client module is pinned to a development version (v0.3.2-0.20240730185603-13c071f0b34d). While this might be necessary for early integration, it could pose stability risks.
Let's verify the compatibility between the IBC-Go and Wasm light client versions:
✅ Verification successful
Let me gather more information about the specific version compatibility and usage.
Let me check one more aspect to understand the integration better.
Development version of Wasm light client module appears stable and properly integrated
Based on the evidence gathered:
- The Wasm light client module is properly initialized using
ibcwasmkeeper.NewKeeperWithVMwith appropriate parameters - The feature was intentionally added as shown in CHANGELOG.md: "feat: enable wasm light clients on IBC (08-wasm)"
- The module is used alongside IBC-Go v7.4.0, which is a stable release
- The development version (v0.3.2-0.20240730185603-13c071f0b34d) appears to be a pre-release that's been specifically integrated and tested with the codebase
While it's a development version, the integration appears intentional and properly configured. The stability risk is mitigated by the proper initialization and its use alongside a stable IBC-Go version.

13-15: Imports added are appropriate
The new import statements for cmtos, cmtproto, and ibcwasmkeeper are necessary for the added IBC WASM functionalities.
246-249: 🛠️ Refactor suggestion
Improve error handling in snapshot extension registration
When registering snapshot extensions, it's beneficial to provide specific error messages for easier debugging. Currently, if an error occurs, the message is generic and doesn't specify which snapshotter failed to register.
Consider modifying the error handling to include the actual error and specify which extension failed:
if err := snapshotManager.RegisterExtensions(
wasmkeeper.NewWasmSnapshotter(
app.CommitMultiStore(),
&app.WasmKeeper,
),
ibcwasmkeeper.NewWasmSnapshotter(
app.CommitMultiStore(),
&app.WasmClientKeeper,
),
); err != nil {
- panic("failed to add wasm snapshot extension.")
+ panic(fmt.Sprintf("failed to register snapshot extensions: %v", err))
}This change will output the specific error encountered during registration.
Likely invalid or redundant comment.
