Injective schedules v1.20.3 mainnet upgrade for July 29 at block 176,273,000

The upgrade follows governance proposal IIP-677 and is expected around 10:00 AM ET / 14:00 UTC. Validators must back up configs, data, and keys, install the v1.20.3 injectived binaries, and restart nodes after the chain halts at the target height. The documentation outlines three outcomes: a successful upgrade within 5-10 minutes, trouble upgrading, or an abort path where the team provides a patched binary within 36 hours. Validators are advised to snapshot data, back up privvalidatorstate.json to prevent double-signing, remove the wasm cache, and downgrade to v1.20.1 if the upgrade fails.
