# Expected chain ID: 4689 / 0x1251Developer signals External dashboards a developer may inspect before choosing where to deploy. Main.net links to these references but does not collect the metric values, normalize methodologies, rank chains, or recommend deployments.
Main.net links to external developer-signal dashboards but does not collect, normalize, rank, or republish their metric values in this version. External metrics can use different methodologies and update schedules. Check the linked provider documentation before comparing chains. These links are not recommendations, rankings, investment advice, or claims that a chain is suitable for a specific application. Safety note IoTeX documentation separates full-node and archive endpoints. Use an archive or dedicated provider when historical state coverage is required.
Main.net is an independent reference site. It does not operate this chain, custody assets, execute transactions, or provide investment advice.
