What is the Monitor Wallet Transactions use case?
An active DeFi user signed dozens of transactions per month across chains with no record of what had been authorised, and no notification when their own addresses moved funds.
What was the outcome?
The inventory found 14 unlimited standing approvals, 9 to contracts unused for over six months, all revoked. Self-monitoring alerts also flagged an approval transaction initiated from a compromised browser session within seconds, before any transfer occurred.
Which tools were used?
On-chain webhooks — activity alerts on the user's own addresses, Approval manager — allowance inventory and revocation, n8n — routing and daily digest, Transaction analysis prompt — plain-language review of unfamiliar signatures.

The vocabulary this page depends on.
- →Web3 Wallet
A Web3 wallet stores your keys and signs transactions, letting you hold assets and connect to on-chain applications without an intermediary.
- →Token Approval
A token approval grants a contract permission to move your tokens — persistent, often unlimited, and the most common source of avoidable losses.
- →Multichain
Multichain means operating across several networks at once — more opportunity, more surfaces to secure and more addresses to monitor.
- →Self-Custody
Self-custody means you control the private keys to your assets, so no company can freeze, lend out or lose them on your behalf.
