Polygon approval checker
See every contract allowed to spend your Polygon tokens, flagged by risk. Free, non-custodial, no wallet connection — just paste your address.
Polygon token approvals, explained
Every time you interact with an Polygon dApp, you grant its contract permission to spend your tokens — often unlimited. WalletWatch reads the Polygon chain's public data and lists every active approval with a plain-English risk score, so you know exactly who can touch your funds.
How to check an Polygon approval
Paste your Polygon address above. We check live allowance state on-chain, cross-reference known scam/safe lists, verify contracts against Polygonscan, and flag unlimited or stale permissions. Dangerous approvals come with the exact link to revoke them.
Monitor it continuously
Upgrade to Pro and we'll re-scan your saved Polygon wallet every 4 hours, alerting you on Telegram and email the moment a new approval appears — so a permission can never hide again.
