## What happened

Axelar on-chain governance proposal 495 passed, authorizing an upgrade of axelar-core to v1.5.3.

## What changed

The v1.5.3 network upgrade is governance-approved. The associated official release describes a Cosmos SDK, IBC-Go and Wasmd migration plus vote-handling, queue-ordering, fee-policy and hardening changes.

## What did not change

The candidate record does not establish that the upgrade has executed at a block height or that all validators are running the new binary.

## Confirmed

- Axelar proposal 495 identifies axelar-core v1.5.3 as the intended upgrade.
- The proposal status is passed.
- An official v1.5.3 release build exists for networks that have not yet run the upgrade.

## Still open

- The scheduled upgrade height and whether execution has occurred.
- Whether validator adoption and post-upgrade chain operation are healthy.
- Whether downstream integrations require configuration or compatibility review.

## What it means for an advisor

- Review Axelar dependency diligence for the approved architecture and security changes before treating the new version as operative.
- Monitor the execution height and chain behavior; approval and release publication do not prove successful migration.
