Passage v4.0.1 — Emergency Fix for the v4.0.0 Tx-Layer Outage

v4.0.0 shipped with three defects from the Cosmos SDK 0.47 → 0.50 port that broke the transaction layer network-wide.

Consensus was healthy, but blocks were empty.

v4.0.1 fixes all three issues.

Important: This is a consensus-affecting change.
All validators must switch at the same height.

Fixes

1. Address Codec in InterfaceRegistry

File: app/params/proto.go

v4.0.0 built the InterfaceRegistry without an address codec.

As a result, any message carrying a pasgvaloper… address could not be built by clients or processed by nodes, including:

• Delegate
• Undelegate
• Redelegate
• Withdraw rewards

The InterfaceRegistry requires a proper address codec implementation.

2. ibctm / Solomachine Light-Client Registration

File: app/app.go

ibc-go v8 no longer bundles the light clients inside ibc.AppModuleBasic.

Without ibctm registered, any decode of:

/ibc.lightclients.tendermint.v1.ClientState

fails.

This breaks:

• IBC client-state queries
• Relayer client updates

3. cosmwasm_1_3 Capability

File: app/app.go

Restored the cosmwasm_1_3 wasm capability that existed in v3.0.0 but was dropped during the port.

This prevents contracts requiring cosmwasm_1_3 from being rejected at store-code.

Diff

Verification

A 22-point verification battery was executed, covering one transaction per wired module:

• Bank

• Staking:

  • Delegate
  • Unbond
  • Redelegate

• Distribution:

  • Withdraw rewards
  • Set withdraw address

• Governance

• Authz

• Feegrant

• IBC transfer

• Wasm

Additional verification included:

• Direct signing
• Amino JSON signing for Ledger
• Decode of all historical governance proposals
• Decode of vesting accounts
• Full LCD query set

Results:

• Passes on v4.0.1
• Fails on v4.0.0 exactly at the three defects listed above
