Upgrades the chain to Cosmos SDK v0.53.8 and IBC-Go v10.7.0. Use the cosmos-sdk-v0.53.8 upgrade plan at the agreed height; replacing the binary alone while reusing the old database is not supported.
The upgrade migrates legacy staking and tokenized-share data, preserving associated claims, balances, and supply.

Walkthrough
IRIS Hub moves to the v5 module path and updates its Cosmos SDK and IBC dependencies. App wiring removes capability support and adds IBC-Go v10 light-client registration. A new SDK 0.53.8 upgrade migrates legacy LSM data and removes capability state.
The module path changes to v5, and dependencies include Cosmos SDK 0.53.8 and IBC-Go v10. Package references, protobuf Go package paths, generation scripts, and build configuration use the updated paths and tool versions.
IBC keeper constructors use updated APIs and runtime store services. The capability keeper and module are removed, Tendermint and Solo Machine clients are registered, and HasTrace uses GetDenom.
SDK upgrade routing and LSM migration app/upgrade.go, app/upgrades/*, app/sdk_upgrade_test.go, docs/migration/cosmos-sdk-v0.53.8.md
The upgrade router registers the SDK 0.53.8 upgrade. The upgrade migrates staking records, preserves validated reward-owner claims, removes legacy LSM records and capability version entries, and then runs module migrations. Tests cover app wiring, IBC denom migration, and staking state normalization.
CLI and validator-genesis compatibility cmd/iris/cmd/*
Validator creation calls supply the updated argument. Validator-genesis tests use raw tokenize-share records, and the genesis command no longer adds a blank --initial-height flag.

irisnet/irishub#3024: It changes overlapping IBC keeper constructor wiring and validator-genesis code, including the authority arguments and tokenize-share tests.
Merge Risk: Moderate · previous review 30199
The upgrade could halt at the upgrade height if any IBC channel is mid-flush at that moment. Confirm no channel is flushing or add a pre-upgrade guard before scheduling the upgrade on a live network.
Security architecture risk: Moderate · up to 7c38e
The new genesis conversion includes ownership, accounting, and rollback protections, but the validation command does not exercise the full initialization path. The PR also changes an existing upgrade handler's staking migration behavior. Their operational exposure needs confirmation before relying on those paths.
Retained concerns
Medium · reliability · inferred: The validation command can certify only preparation and module-level validation, not the additional cross-module invariants and keeper operations required for live LSM conversion. Acceptance by the command therefore does not establish that initialization will succeed; the existence and exposure of an accepted-but-failing production genesis remain unverified.
Medium · reliability · inferred: The registered v3 handler no longer performs the staking migration previously run at that upgrade. If this binary executes a v3 plan against pre-v3 state, its staking transition differs from the previous handler, with potential staking-accounting or replay consequences. Whether that execution path is supported or reachable in deployment is unknown.
Security review details
Security Blast Radius
inferred — Genesis input can affect chain-wide bank supply, staking claims, and distribution rewards if a node accepts it. The changed InitChainer retains its existing BaseApp callback rather than adding a new network-facing caller; who can supply production genesis is not established.
Trust Boundaries and Controls
observed — Preflight checks holder identity and derivative custody before writes. Live migration checks initial and final accounting invariants and commits its cached state only after successful conversion.
Resilience and Maintainability Implications
inferred — The conditional cache strengthens failure containment for nonempty LSM plans without removing a cache from ordinary genesis: the target-branch InitChainer performed direct module initialization.
Hardening Proposals
proposed — Establish which historical upgrade and snapshot starting points this binary supports, and compare validated legacy genesis fixtures with full InitChain outcomes to establish validation parity.

The root-level validate command still uses the SDK validator. It rejects legacy LSM genesis files that InitChain accepts.
Lines 198-203 replace the genesis validate subcommand with validateGenesisCmd(basicManager). That command runs app.ValidateGenesis, which runs the LSM Prepare preflight.
Line 165 still registers genutilcli.ValidateGenesisCmd(basicManager) on the root command. In SDK v0.50+, this command uses Use: "validate [file]" and has the validate-genesis alias. It calls basicManager.ValidateGenesis directly. For the staking module, that call reaches lsmgenesis.StakingModule.ValidateGenesis with allowLive=false.
The result is two different outcomes for the same file:
iris validate genesis.json fails with contains N live LSM entries.
iris genesis validate genesis.json passes.
InitChainer accepts the same file and migrates the records.
The SDK validator also skips the bank/auth ownership checks. Operators who use the root command get a false rejection before the upgrade.
Register the application-wide validator at the root level too.

State defines if a channel is in one of the following states: CLOSED, INIT, TRYOPEN, OPEN, FLUSHING, FLUSHCOMPLETE or UNINITIALIZED.
const (
// Default State
UNINITIALIZED State = 0
// A channel has just started the opening handshake.
INIT State = 1
// A channel has acknowledged the handshake step on the counterparty chain.
TRYOPEN State = 2
// A channel has completed the handshake. Open channels are
// ready to send and receive packets.
OPEN State = 3
// A channel has been closed and can no longer be used to send or receive
// packets.
CLOSED State = 4
// A channel has just accepted the upgrade handshake attempt and is flushing in-flight packets.
FLUSHING State = 5
// A channel has just completed flushing any in-flight packets.
FLUSHCOMPLETE State = 6
)
#### func (State) EnumDescriptor ¶
func (State) EnumDescriptor() ([]byte, []int)
#### func (State) String ¶
func (x State) String() string
#### type Timeout ¶
type Timeout struct {
// block height after which the packet or upgrade times out
Height types.Height `protobuf:"bytes,1,opt,name=height,proto3" json:"height"`
// block timestamp (in nanoseconds) after which the packet or upgrade times out
Timestamp uint64 `protobuf:"varint,2,opt,name=timestamp,proto3" json:"timestamp,omitempty"`
}
Timeout defines an execution deadline structure for 04-channel handlers. This includes packet lifecycle handlers as well as the upgrade handshake handlers. A valid Timeout contains either one or both of a timestamp and block height (sequence).
#### func (*Timeout) Descriptor ¶
func (m *Timeout) XXX_Merge(src proto.Message)
#### func (*Timeout) XXX_Size ¶
func (m *Timeout) XXX_Size() int
#### func (*Timeout) XXX_Unmarshal ¶
func (m *Timeout) XXX_Unmarshal(b []byte) error
#### type Upgrade ¶
type Upgrade struct {
Fields UpgradeFields `protobuf:"bytes,1,opt,name=fields,proto3" json:"fields"`
Timeout Timeout `protobuf:"bytes,2,opt,name=timeout,proto3" json:"timeout"`
NextSequenceSend uint64 `protobuf:"varint,3,opt,name=next_sequence_send,json=nextSequenceSend,proto3" json:"next_sequence_send,omitempty"`
}
Upgrade is a verifiable type which contains the relevant information for an attempted upgrade. It provides the proposed changes to the channel end, the timeout for this upgrade attempt and the next packet sequence which allows the counterparty to efficiently know the highest sequence it has received. The next sequence send is used for pruning and upgrading from unordered to ordered channels.

<excerpt>citeturn0search2 [wordlim: 200] Crawled: 2 weeks ago; 1.23 | v10.7 | v0.53 | v0.38 ... Callbacks middleware has been merged into `ibc-go` since v10.
Only the following major release series have a stable release status. All missing minor release versions have been discontinued.
We reserve the right to drop support for releases if they are deemed unused (for example, because the Cosmos SDK version they depend on is not used or has been deprecated). Likewise, we also reserve the right to drop support for pre v1.0 versions of modules if we deem them unnecessary to maintain (we are only looking to give support for stable major releases).
### ibc-go
Release | End of Life Date
--- | ---
`v10.7.x` | Mar 10, 2027
`v11.1.x` | Apr 10, 2028
### `08-wasm` light client proxy module
Release | End of Life Date
--- | ---
`v10.5.x` | Mar 10, 2027

### What pull requests will be included in stable patch-releases?
Pull requests that fix bugs and add features that fall in the following categories:
* Severe regressions.
* Bugs that may cause client applications to be largely unusable.
* Bugs that may cause state corruption or data loss.
* Bugs that may directly or indirectly cause a security vulnerability.
* Non-breaking features that are strongly requested by the community.
* Non-breaking CLI improvements that are strongly requested by the community.
### What pull requests will NOT be automatically included in stable patch-releases?
As rule of thumb, the following changes will NOT be automatically accepted into stable point-releases:
* State machine changes, unless the previous behaviour would result in a consensus halt.
* Protobuf-breaking changes.
* Client-breaking changes, i.e. changes that prevent gRPC, HTTP and RPC clients to continue interacting with the node without any change.
* API-breaking changes, i.e. changes that prevent client applications to build without modifications to the client application's source code.
* CLI-breaking changes, i.e. changes that require usage changes for CLI users.

Block the upgrade while any IBC channel is flushing.
The sdk0538 upgrade handler calls m.RunMigrations(ctx, c, fromVM). The chain currently runs ibc-go v8.7.0, whose core consensus version is 6. The handler therefore also runs IBC's 7→8 channel migration. That migration fails if any channel is in FLUSHING or FLUSHCOMPLETE. If that happens, the upgrade handler returns an error and the upgrade cannot complete at the upgrade height.
Add a pre-upgrade check that no channel is in FLUSHING or FLUSHCOMPLETE. Run the check shortly before the upgrade height, and complete any in-progress channel upgrades before the chain reaches that height.

Review comment at @go.mod at line 53:
Add a pre-upgrade check to the sdk0538 upgrade flow that rejects the upgrade
while any IBC channel is FLUSHING or FLUSHCOMPLETE. Schedule the check shortly
before the upgrade height and ensure in-progress channel upgrades are completed
before that height.
