Patches

State-Sync AppHash Error Fix

• StateSync nodes must recover .firmachain/data/wasm from on-chain store to avoid App Hash mismatch #11
• Issue: Nodes bootstrapping via state-sync would halt with AppHash mismatch on smart contract transactions.
• Root Cause: CosmWasm contract data (code, pinned codes, checkpoints) was missing from state-sync snapshots.
• Solution: Patch ensures CosmWasm data is included in state-sync snapshots.

Requirements

• Go: v1.21 (same as v0.5.0)

Tests

• Local: Unit Tests, CLI Commands
• Devnet: Unit Tests, CLI Commands, E2E Tests
• Testnet (Imperium-4): Unit Tests, CLI Commands, E2E Tests, Smart Contract Transactions (state-sync validation)

Detailed Description

This patch is a non-breaking, non-governance upgrade that resolves AppHash mismatch errors observed on state-synced nodes when processing smart contract transactions.

Key changes:

• Ensures state-sync snapshots now include all CosmWasm contract data:
  • Contract code
  • Pinned codes
  • Checkpoints
• Prevents divergence between fresh state-synced nodes and long-running nodes.
• Stabilizes network bootstrap process and smart contract execution.

Who Should Upgrade

• Required:

  • State-sync providers (to generate valid snapshots)
  • State-sync users (to restore successfully from snapshots)

• Recommended:

  • All validators and full nodes (to prevent future issues and improve stability)
