Know Chain Support Before Starting Your Multi-Chain Project
Create a new project and instantly see which blockchains Blocknative monitors. No support surprises mid-project.
Trigger
Project Created
Fires when a new Linear project is created. Covers projects in both public and private teams — polls with the connected user's token, so visibility matches what the connected user can see in Linear.
Action
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Why this helps
Kicking off multi-chain work and discovering halfway through that a chain isn't supported disrupts planning and wastes time.
- Verify chain support before committing to timelines
- Avoid mid-project discovery of unsupported networks
- Plan multi-chain work with full visibility
- Make confident infrastructure decisions
Setup
Build it in a few focused steps.
- 1Connect Linear and Blocknative to Notis (one-time portal setup).
- 2Tell Notis: 'When I create a new Linear project, show me which chains Blocknative supports.' Use chat or the automation builder.
- 3Select 'Project Created' as the trigger and choose your notification channel.
- 4Create a test project and verify the list of supported chains appears immediately.
- 5From now on, every new project automatically surfaces chain support information.
Questions about this workflow
Will I see only Blocknative-supported chains or all chains?
Only supported chains - Notis filters to show exactly what you can monitor, eliminating guesswork.
Can I export this list to share with my team?
Yes - the automation delivers the list to your notification channel (Slack, email, etc.) where anyone can save or share it.
Do these chains change frequently?
Blocknative adds support periodically. Each automation run fetches current data, so you're never working with outdated info.

Tool to retrieve the current mempool gas price distribution breakdown. use when analyzing gas price trends or preparing fee strategies.
Comment Received Trigger
Triggered when a comment is received.
Get Gas Oracles
Tool to retrieve metadata on supported gas oracles per chain. use when you need to dynamically discover all available on-chain gas estimation oracles across networks.
Issue Created Trigger
Triggered when a new issue is created.
Get Gas Prices
Tool to fetch gas price estimates for specific inclusion probabilities. use when you need gas price ranges for the next block or next ~10 seconds.
Issue Updated Trigger
Triggered when an issue is updated. For example labels are changed, issue status is changed, etc.
Get Supported Chains
Tool to retrieve supported chains metadata. use when discovering available networks for blocknative gas services.
Private Team Comment Created
Fires when a new comment is posted on an issue in a private Linear team (polled with the connected user's token).
Get Base Fee Estimates
Tool to get real-time predictions for base fee and blob base fee for the next 5 blocks. use when you need both 99% and 50% confidence estimates for upcoming blocks.
Private Team Issue Created
Fires when a new issue appears in a private Linear team (polled with the connected user's token).
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.
Private Team Issue Properties Updated
Fires when properties on an issue change in a private Linear team (polled with the connected user's token).
Subscribe Transaction Hash
Tool to subscribe to transaction state change events of an ethereum transaction hash. use after establishing a blocknative websocket connection to prepare the subscription message.
