The problem it solves
DeFi protocols rely on delicate economic invariants. When an oracle pauses or a pool experiences an abnormal liquidity drain, manual monitoring is too slow to trigger mitigations before bad debt or arbitrage attacks occur.
Monitors the wallet addresses, contracts, and on-chain thresholds you configure, and raises contextual alerts when those conditions are met. It reports; it never signs transactions or moves funds.
Who it's for
Protocols tracking treasury wallets, governance contracts, or staking pools
DeFi teams monitoring liquidity positions, price feeds, or protocol parameters
Security and operations teams that need immediate notice of unusual on-chain activity
Capabilities
Monitors configured addresses and contracts
Watches defined event patterns
Alerts on threshold breaches
Includes transaction context in alerts
Explicit limitations
What this agent deliberately does not do — so there are no surprises after purchase.
Read-only: never signs or executes transactions
