How this service works
Build powerful blockchain workflow automations with a visual, node-based editor. Built with Next.js and React Flow.
Output
Returns EVM-compatible calldata including the target contract address (to), the encoded function call data (data, starting with ERC-20 transfer selector 0xa9059cbb), the transaction type ('calldata'), and the ETH value to send (value). This calldata can be submitted to a blockchain node or wallet to execute the protection action on-chain.
Example use cases
Emergency vault lockdown on suspicion
“Someone is trying to drain my DeFi vault at address 0x1234567890abcdef1234567890abcdef12345678 — can you trigger the sentinel vault protection workflow right now? The reason is 'unauthorized withdrawal attempt detected'.”
Scheduled daily vault security check
“Every morning, run the sentinel vault protection workflow on my vault at 0xdeadbeefdeadbeefdeadbeefdeadbeefdeadbeef with the reason 'routine daily security sweep' to keep it guarded.”
Post-deployment vault hardening
“I just deployed a new smart contract vault at 0xaabbccddeeff00112233445566778899aabbccdd — please activate the sentinel protection workflow on it with reason 'new vault initialization hardening'.”
Technical details
Endpoint
POSThttps://app.keeperhub.com/api/mcp/workflows/sentinel-vault-protection/call?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need to programmatically trigger a predefined sentinel vault protection automation on KeeperHub for a specific blockchain vault address. It is best suited for automated security pipelines, keeper bots, or agent workflows that need to generate on-chain calldata for vault protection without manually constructing smart contract calls. Prefer this over generic blockchain transaction builders when you have a vault already registered on KeeperHub and want to invoke its associated sentinel workflow.
Side effects
- Missing or invalid vaultAddress — request will fail with a validation error
- Vault address not recognized or not registered in KeeperHub — workflow may return empty or error response
- Payment failure — x402 payment of 0.05 USDC must succeed before the workflow is triggered
- Network or RPC error causing calldata generation to fail
- Workflow misconfiguration on the KeeperHub platform resulting in malformed calldata
