The Metalayer bridge widget ships with a curated list of chains that are supported out of the box. The SDK keeps this dataset in sync; call client.getSupportedChains() to retrieve the latest information for your environment instead of hard-coding chain metadata. All Caldera-hosted chains are scheduled to land in the widget as they go live, so expect this table to expand alongside the Caldera ecosystem.
