Subscribe Multichain
Tool to generate websocket subscription details for events across multiple chains. use when preparing to track a transaction hash or account address across chains via blocknative multichain sdk.
Why this helps
Monitoring activity across multiple chains requires setting up separate subscriptions in Blocknative for each network, multiplying setup friction.
- Monitor all chains from one Linear issue
- Eliminate repetitive subscription setup
- Aggregated alerts across networks
- Unified view of cross-chain activity
Setup
Build it in a few focused steps.
- 1Connect Linear and Blocknative integrations in Notis (one-time setup).
- 2Tell Notis: 'When I create an issue for cross-chain monitoring, subscribe to events across all networks.' Use chat or automation builder.
- 3Select 'Issue Created' as the trigger and add a label filter like 'multichain' to scope appropriately.
- 4Create a test issue with the relevant label and confirm multichain subscriptions activate.
- 5Your team can now launch cross-chain monitoring with a single Linear task.
Questions about this workflow
Which chains will be included in the multichain subscription?
Notis can target all supported chains or you can specify them in the issue (e.g., 'monitor Mainnet, Polygon, Arbitrum').
Will I get separate alerts for each chain?
Yes - Blocknative delivers chain-specific event streams so you see exactly where activity is happening.
Can I add or remove chains from an existing subscription?
Yes - update the issue and Notis adjusts subscriptions to match your current monitoring scope.
