Hi all, we have released a new version of heimdall-v2, v0.2.5 (ONLY FOR AMOY).

This solves a bug in an API used to fetch state syncs and also provide an endpoint for v2 version.

Steps for Upgrading Heimdall

Before proceeding, please create a backup of your heimdall config file whose default location is: /var/lib/heimdall/config/config.toml. This might differ if you have setup heimdall at a different location.

  1. Stop heimdalld service

    sudo service heimdalld stop

  2. Install heimdall with a version tag, network name (amoy), and node type (sentry or validator).

    # Replace the network and node type
curl -L https://raw.githubusercontent.com/maticnetwork/install/heimdall-v2/heimdall-v2.sh | bash -s -- v0.2.5 <network> <node_type>

  3. Check heimdall version

    /usr/bin/heimdalld version

# It should print
# 0.2.5

  4. Restart heimdall service

    sudo service heimdalld start

  5. Restart the telemetry services

    sudo service telemetry restart

What’s Changed

Full Changelog: v0.2.4…v0.2.5

WebSocket for Bor–Heimdall communication

Also, we remind you to enable WebSocket support in your bor config.toml for the migrated amoy nodes. file. After the migration, to optimize communication between Heimdall and Bor, you can (optionally) enable WebSockets. By default, heimdall-v2 polls bor by using frequent HTTP requests, which can be inefficient. Enabling WebSocket support reduces overhead and improves sync responsiveness.

Edit your bor config.toml file and add the following under the [heimdall] section:

[heimdall]
ws-address = "ws://localhost:26657/websocket"

This assumes Heimdall-v2 is running with its WebSocket endpoint enabled on port 26657.

Adjust the port or host if your setup differs.

After updating, restart your Bor node to apply the new configuration.

Thanks,

Polygon Team
