Get signed HTTP notifications the moment transactions, blocks, delegations or epochs are confirmed on Cardano mainnet. No node, no indexer, no polling.
Events fire per block with the confirmation depth you choose (1–10), so you decide the safety/latency trade-off.
Match on addresses, amounts, policy IDs, asset fingerprints, pools - or any field via JSONPath conditions.
Every request carries an HMAC-SHA256 Delivery-Signature header so you can verify it's really us.
Agents create self-expiring webhooks with one call - no account, no server needed. Inbox mode stores events for polling. MCP server and llms.txt included.
Events fire only at your chosen confirmation depth (1-10). Deterministic event IDs make consumers idempotent under at-least-once delivery.
Inspect recent deliveries, response codes and errors for every webhook right in the dashboard.
Pick what you want to hear about - filter it down with conditions.
Fires for transactions matching your filters: recipient, sender, quantity, policy ID, fingerprint, asset or JSONPath.
Fires for every confirmed block, or only blocks matching pool, size, height, fees or output filters.
Fires when stake is delegated - track delegations to your pool as they happen.
Fires when a new epoch starts. Perfect for schedules, snapshots and reward automation.
Fires when a new governance action lands on-chain - treasury withdrawals, parameter changes, hard forks and more.
Fires when DReps, SPOs or the constitutional committee vote on recent governance actions.
Fires on pool registrations, parameter updates and retirements - know instantly if your pool raises fees or retires.
Fires when rewards are withdrawn - reconcile flows for treasuries, DAOs and exchanges.
Fires when assets are minted or burned under a policy - drop monitoring, supply tracking, burn events.
Fires when a Plutus validator executes - watch your protocol's contracts in near-real-time.
Fires when a new DRep registers - keep governance dashboards live.
Fires when a watched stake account changes: balance, rewards or delegation.
