❗️ Important notice for TAC node operators

The TAC mainnet upgrade v1.6.0 is scheduled for June 30, 2026, ~12:00 UTC (block ~21,776,800).

If you run a TAC node, action is required before the upgrade height:

• Upgrade to the v1.6.0 binary
• Set evm-chain-id = 239 in app.toml

We also recommend running Cosmovisor to apply the upgrade automatically at the scheduled height, no manual intervention needed at block time.
