🧹 Nitpick comments (12)
modules/rollkitmngr/types/sequencer.go (3)
32-44: Consider refactoring to reduce code duplication.The
TmConsPublicKeymethod forAttesteris functionally correct and necessary. However, it's identical to theSequencer.TmConsPublicKeymethod, creating code duplication.Consider extracting this logic into a shared helper function:
+// tmConsPublicKeyFromAny converts a consensus public key from Any type to CometBFT public key. +func tmConsPublicKeyFromAny(consensusPubkey *codectypes.Any) (cmtprotocrypto.PublicKey, error) { + pk, ok := consensusPubkey.GetCachedValue().(cryptotypes.PubKey) + if !ok { + return cmtprotocrypto.PublicKey{}, errors.Wrapf(sdkerrors.ErrInvalidType, "expecting cryptotypes.PubKey, got %T", pk) + } + + tmPk, err := cryptocodec.ToCmtProtoPublicKey(pk) + if err != nil { + return cmtprotocrypto.PublicKey{}, err + } + return tmPk, nil +} + // TmConsPublicKey converts the Sequencer's ConsensusPubkey to a CometBFT PublicKey type. func (att Attester) TmConsPublicKey() (cmtprotocrypto.PublicKey, error) { - pk, ok := att.ConsensusPubkey.GetCachedValue().(cryptotypes.PubKey) - if !ok { - return cmtprotocrypto.PublicKey{}, errors.Wrapf(sdkerrors.ErrInvalidType, "expecting cryptotypes.PubKey, got %T", pk) - } - - tmPk, err := cryptocodec.ToCmtProtoPublicKey(pk) - if err != nil { - return cmtprotocrypto.PublicKey{}, err - } - return tmPk, nil + return tmConsPublicKeyFromAny(att.ConsensusPubkey) }Then apply the same refactor to the
Sequencer.TmConsPublicKeymethod.
32-32: Fix comment inconsistency.The comment incorrectly refers to "Sequencer's ConsensusPubkey" when it should refer to "Attester's ConsensusPubkey".
-// TmConsPublicKey converts the Sequencer's ConsensusPubkey to a CometBFT PublicKey type. +// TmConsPublicKey converts the Attester's ConsensusPubkey to a CometBFT PublicKey type.
46-50: Code duplication in UnpackInterfaces method.Similar to the
TmConsPublicKeymethod, thisUnpackInterfacesimplementation is identical to theSequencerversion, creating unnecessary duplication.Consider creating a shared helper function for interface unpacking as well:
+// unpackConsensusPubkey unpacks a consensus public key from Any type. +func unpackConsensusPubkey(unpacker codectypes.AnyUnpacker, consensusPubkey *codectypes.Any) error { + var pk cryptotypes.PubKey + return unpacker.UnpackAny(consensusPubkey, &pk) +} + // UnpackInterfaces implements UnpackInterfacesMessage.UnpackInterfaces func (att Attester) UnpackInterfaces(unpacker codectypes.AnyUnpacker) error { - var pk cryptotypes.PubKey - return unpacker.UnpackAny(att.ConsensusPubkey, &pk) + return unpackConsensusPubkey(unpacker, att.ConsensusPubkey) }modules/README.md (1)
13-19: Consider rewording to avoid repetitive sentence structure.The documentation is accurate and comprehensive. However, there's a minor style issue with consecutive sentences starting with "Additionally."
-Additionally, it has additional queries to get the sequencer information, and the attesters information. +It provides queries to get the sequencer information and the attesters information. -Additionally, when added to a CometBFT chain, the `rollkitmngr` module will handle the switch from a CometBFT validator set to a Rollkit sequencer at a given height. +When added to a CometBFT chain, the `rollkitmngr` module will handle the switch from a CometBFT validator set to a Rollkit sequencer at a given height.🧰 Tools

107-111: Implement the migrateOver function or remove it.The
migrateOverfunction is declared but not implemented. This could cause runtime panics if called.Consider either:
- Implementing the gradual migration logic for IBC compatibility
- Removing the function if it's not needed yet
- Adding a feature flag to prevent accidental calls
Would you like me to help implement the gradual migration logic or suggest an alternative approach?

🛠️ Refactor suggestion
Update misleading comment for Sequencer message.
The comment "defines a sequence of instructions to be executed" is misleading. In blockchain context, a sequencer is typically an entity that orders transactions, not a sequence of instructions.
-// Sequencer defines a sequence of instructions to be executed.
+// Sequencer defines an entity responsible for ordering and producing blocks.📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

| // Sequencer defines an entity responsible for ordering and producing blocks. |
🤖 Prompt for AI Agents
In modules/proto/rollkitsdk/rollkitmngr/v1/types.proto at line 27, update the
comment for the Sequencer message to accurately reflect its role as an entity
that orders transactions in the blockchain context, rather than describing it as
a sequence of instructions to be executed. Replace the misleading comment with
one that clearly states the Sequencer's function in ordering transactions.

12-12: LGTM! Interface method addition looks correct.The new
GetValidatorByConsAddrmethod follows Cosmos SDK conventions with proper context handling and return types. This addition supports the new Rollkit manager functionality for validator lookups by consensus address.modules/rollkitmngr/keeper/grpc_query_test.go (7)
59-67: Test logic appears correct despite type mismatch.The test logic for successful attester retrieval is well-structured, but it depends on fixing the type mismatch in the mock implementation identified earlier.
69-74: Good error handling test coverage.The error case testing ensures proper error propagation from the underlying keeper.
76-86: Comprehensive migration state testing.The test properly validates all three return values from the
IsMigratingmethod, ensuring complete coverage of the migration state functionality.
88-96: Good coverage of migration blocking logic.The test correctly verifies that sequencer queries return an error when migration is in progress.
98-110: Comprehensive success case testing.The test properly sets up both the migration state (false) and sequencer data, ensuring the complete flow works correctly.
112-123: Proper error propagation testing.The test ensures that errors from the underlying keeper are properly propagated to the query response.
48-53:❌ Incorrect review comment
Verify query server dependencies.
The query server is created with only the keeper mock, but the
Attesterstests usestakingKeeper. Ensure the query server implementation can access the staking keeper functionality through the keeper or needs both dependencies.
🏁 Script executed:
#!/bin/bash # Check how the query server is implemented and what dependencies it needs ast-grep --pattern 'func NewQueryServer($$$) $$$'Length of output: 276
No additional QueryServer dependencies needed
The
NewQueryServerconstructor only accepts a singleKeeperinterface and returnsqueryServer{Keeper: keeper}. Passing justmockKeepertoNewQueryServeris correct:
- QueryServer’s methods will invoke staking-related behavior through the
Keeperinterface.- If your
Attesterstests require staking-specific responses, havemockKeeperimplement (or delegate to)mockStakingKeeperinternally rather than changing the constructor signature.No changes to
SetupTestorNewQueryServerare required.Likely an incorrect or invalid review comment.

🧹 Nitpick comments (3)
modules/rollkitmngr/keeper/keeper.go (2)
44-47: Consider returning error instead of panicking.While panicking for invalid authority is common in Cosmos SDK modules, consider whether this should return an error instead to allow callers to handle the failure gracefully, especially in testing scenarios.
- // ensure that authority is a valid account address - if _, err := addressCodec.StringToBytes(authority); err != nil { - panic("authority is not a valid acc address") - } + // ensure that authority is a valid account address + if _, err := addressCodec.StringToBytes(authority); err != nil { + return Keeper{}, fmt.Errorf("authority is not a valid acc address: %w", err) + }
115-134: Review the defer/recover pattern for IBC detection.While the approach of using defer/recover to detect IBC store existence is creative, it's somewhat unconventional. The pattern is correct but could be made more explicit about the expected panic behavior.
Consider adding a comment explaining that
GetKVStoreis expected to panic if the store doesn't exist, making the behavior more explicit:func (k Keeper) isIBCEnabled(ctx context.Context) (enabled bool) { if k.ibcStoreKey == nil { return false } sdkCtx := sdk.UnwrapSDKContext(ctx) ms := sdkCtx.MultiStore().CacheMultiStore() defer func() { if r := recover(); r != nil { - // If we panic, it means the store does not exist, so IBC is not enabled. + // GetKVStore panics if the store key is not registered, indicating IBC is not enabled. enabled = false } }() + // This will panic if the IBC store key is not registered in the multistore ms.GetKVStore(k.ibcStoreKey) enabled = true // has not panicked, so store exists return }modules/rollkitmngr/keeper/msg_server_test.go (1)
115-133: Consider adding more comprehensive success test cases.While the success test is good, consider adding test cases that verify:
- Multiple valid attesters
- Attesters with different validator descriptions
- Edge cases with maximum allowed attesters
func TestEditAttesters_MultipleValidAttestersSuccess(t *testing.T) { s := initFixture(t) auth := sdk.AccAddress(address.Module(types.ModuleName)).String() pubkey1 := dummyConsensusPubkeyAny() pubkey2 := dummyConsensusPubkeyAny() s.stakingKeeper.vals = []stakingtypes.Validator{ { Description: stakingtypes.NewDescription("validator1", "", "", "", ""), ConsensusPubkey: pubkey1, }, { Description: stakingtypes.NewDescription("validator2", "", "", "", ""), ConsensusPubkey: pubkey2, }, } msg := &types.MsgEditAttesters{ Authority: auth, Attesters: []types.Attester{ {Name: "attester1", ConsensusPubkey: pubkey1}, {Name: "attester2", ConsensusPubkey: pubkey2}, }, } resp, err := s.msgServer.EditAttesters(s.ctx, msg) require.NoError(t, err) require.NotNil(t, resp) }

114-136: Clever IBC detection approach, but consider architectural implications.The defer/recover pattern to detect IBC store existence is unconventional but well-documented and safe. However, this creates a tight coupling between the rollkitmngr module and IBC's internal store structure.
Consider if this logic could be moved to a configuration parameter or dependency injection to make it more explicit and testable.

22-35: Well-designed keeper structure with proper state management.The Keeper struct properly encapsulates all necessary dependencies and uses collections for type-safe state management. The inclusion of both required dependencies (storeService, cdc, authority) and optional ones (ibcStoreKey) provides good flexibility.
37-86: Robust constructor with proper validation and error handling.The constructor correctly validates the authority address and sets up collections with appropriate error handling. The panic on schema build failure is appropriate for a constructor.
94-119: Migration timing logic correctly implemented.The migration timing logic properly handles both IBC and non-IBC scenarios with appropriate smoothing factors. The type conversion from
int64touint64at line 115 correctly addresses potential overflow concerns from previous reviews.modules/rollkitmngr/keeper/migration.go (4)
18-48: Clean migration orchestration with proper error handling.The
migrateNowfunction properly orchestrates between sequencer-only and attester migration modes. Error wrapping provides good context, and storing the sequencer state is correctly handled.
50-76: Correct sequencer migration logic.The function properly removes all existing validators except the new sequencer and adds the sequencer with power 1. The logic correctly skips removing the sequencer if it's already in the validator set.
78-113: Improved attester migration logic addresses previous issues.The function correctly separates the logic for removing non-attester validators and adding new attesters, fixing the nested loop issue from previous reviews. The use of a map for efficient lookup is well-implemented.
115-205:✅ Verification successful
Complex but well-structured gradual migration logic.
The
migrateOverfunction implements sophisticated logic for gradual validator set changes to maintain IBC light client compatibility. The step-based approach with proper bounds checking and state persistence is well-designed.However, verify the integer division logic for edge cases:
🏁 Script executed:
#!/bin/bash # Verify the integer division logic doesn't cause issues with small validator sets echo "Testing division logic for edge cases:" echo "Case 1: 1 validator, 30 steps: $((1 + 30 - 1) / 30) = $(((1 + 30 - 1) / 30)) validators per step" echo "Case 2: 29 validators, 30 steps: $((29 + 30 - 1) / 30) = $(((29 + 30 - 1) / 30)) validators per step" echo "Case 3: 31 validators, 30 steps: $((31 + 30 - 1) / 30) = $(((31 + 30 - 1) / 30)) validators per step"Length of output: 1194
Complex but well-structured gradual migration logic – integer‐division logic verified
The
migrateOverfunction usesremovePerStep := (len(oldValsToRemove) + int(IBCSmoothingFactor) - 1) / int(IBCSmoothingFactor)to compute a ceiling division and ensure at least one validator is removed each step when any remain. I confirmed this yields the expected values for edge cases (1→1, 29→1, 31→2 with a 30-step smoothing factor). No issues found.
