📝 Walkthrough

Walkthrough

The changes move IRIS Hub to the v5 module path and update Cosmos SDK and IBC dependencies. App wiring removes capability module support and adapts IBC keepers and routes. A new SDK 0.53.8 upgrade removes the capability store and version-map entry. Genesis handling adds LSM normalization and migration. Build, generation, and migration documentation are also updated.

Changes

IRIS Hub v5 and SDK 0.53.8 Upgrade

Layer / File(s) Summary
Module versions and v5 package paths
go.mod, proto/irishub/*, modules/guardian/*, modules/mint/*, cmd/iris/*, client/lite/swagger.go, app/rpc/*, app/sim_bench_test.go, testutil/app.go
The module path changes to v5. The Go directive and dependencies are updated. Guardian, mint, command, test, and protobuf package references use v5 paths.
IBC v10 app wiring and capability removal
app/ante/*, app/app.go, app/keepers/*, app/modules.go, app/sim_test.go, app/sdk_upgrade_test.go, wrapper/token.go
Keepers and module registration use IBC-Go v10 APIs, configure light-client routes and governance authorities, and remove capability keeper and module wiring. Tests check app routes, first-block execution, and IBC denom migration. HasTrace uses GetDenom.
SDK upgrade routing and migrations
app/upgrade.go, app/upgrades/*, app/sdk_upgrade_test.go
The router registers the SDK 0.53.8 upgrade. The upgrade removes capability from the store and module version maps before migrations. The v300 LSM migration is removed, and ICA initialization uses default genesis and InitGenesis.
LSM genesis normalization and migration
app/app.go, app/genesis/lsm/*, app/lsm_genesis_test.go, app/modules.go
Staking genesis normalization removes legacy LSM fields under validation rules. Genesis preparation validates legacy records and builds a conversion plan. Initialization applies the plan in a cached context and checks accounting invariants.
Application genesis validation command
cmd/iris/cmd/genesis_validate.go, cmd/iris/cmd/genesis_validate_test.go, cmd/iris/cmd/root.go
The genesis command replaces the SDK validation subcommand with application-wide validation. The CLI test checks legacy staking input and rejects a tokenize-share record without matching bank principal.
Build, release, and migration support
.github/workflows/*, Dockerfile, Makefile, scripts/*, sims.mk, docs/migration/cosmos-sdk-v0.53.8.md
Workflows pin Go 1.24.9, Docker images are configurable through build arguments, and build and generation configuration uses v5 paths. The migration guide records upgrade details and verification limits.

Merge Risk: 🟡 Moderate · up to 7c38e

A supported legacy genesis can initialize successfully but fail the root-level validation command. Use the application-level genesis validator until the commands agree, and correct the migration-guide link before relying on it.

Security Architecture Review

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.

github cosmos ibc-go v10.7.0 v8.1 to v10 migration guide 13-v8_1-to-v10.md

💡 Result:

The migration guide is **[`13-v8_1-to-v10.md`](https://github.com/cosmos/ibc-go/blob/v10.7.0/docs/docs/05-migrations/13-v8_1-to-v10.md)** in the `v10.7.0` tag. It covers the v8.1→v10 changes, including IBC v2 wiring, light-client modules, keeper constructor updates, and removal of the capability and fee modules. The current docs page has the guide’s contents if the tagged GitHub file doesn’t load. ([docs.cosmos.network](https://docs.cosmos.network/ibc/next/migrations/v8_1-to-v10))

site:docs.cosmos.network/ibc/next/migrations/v8_1-to-v10 IBC v8.1 v10 migration guide

💡 Result:

The **IBC-Go v8.1 → v10 migration guide** covers these main changes for chains:

- Wire up the new **IBC v2 transfer stack** and separate light-client modules.
- Update keeper constructors and KV store services.
- Remove the legacy client proposal route, capability keeper/scoped keepers, and **29-fee** middleware.
- Update imports for the v10 Wasm light-client module and callbacks middleware, if used.

The guide also includes code examples for updating transfer and ICA middleware stacks. ([docs.cosmos.network](https://docs.cosmos.network/ibc/next/migrations/v8_1-to-v10?utm_source=openai))

🟡 Minor · The root-level validate command still uses the SDK validator. It rejects legacy LSM… · root.go:165

cmd/iris/cmd/root.go:165
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

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.

Proposed fix
 		genutilcli.InitCmd(basicManager, iristypes.DefaultNodeHome),
-		genutilcli.ValidateGenesisCmd(basicManager),
+		validateGenesisCmd(basicManager),
 		AddGenesisAccountCmd(iristypes.DefaultNodeHome),
