What Is Scroll?
Scroll is an EVM-compatible blockchain supporting smart contracts and decentralized applications, compatible with MetaMask and most popular Web3 wallets.
What Are Scroll Token Approvals?
Every time you swap tokens, deposit into DeFi protocols, or interact with any DApp on Scroll โ you sign an approval granting that smart contract permission to spend your tokens. These approvals persist on the blockchain permanently until you explicitly revoke them.
If an approved contract gets hacked or compromised later, all your approved tokens can be drained in a single transaction. Regularly checking and revoking approvals is the simplest and most effective way to protect your assets.
How to Revoke Scroll Token Approvals
Enter your wallet address in the search field above and select Scroll in the blockchain selector. The tool scans your complete approval history and lists every contract authorized to spend your tokens. Each approval shows which token, which contract, and how much it can withdraw. Click Revoke to cancel each approval.
Frequently Asked Questions
How much does revoking a Scroll token approval cost?
Very little โ typically just $0.01 to $0.1 depending on the chain and current conditions, as gas fees are very low today. You only spend a small amount of native token for gas; the tokens you're revoking access to are never affected.
Is revoking a token approval safe?
Completely safe. Revoking simply calls approve(spender, 0) โ no different from a swap or transfer. You never enter your seed phrase or private key anywhere. The tool reads public approval data from the blockchain and sends the revoke transaction through your connected wallet โ your wallet (like MetaMask) will show a confirmation popup before anything is sent.
Do Scroll approvals expire automatically?
No. Token approvals persist on the blockchain permanently until you explicitly revoke them. Even if you stop using a DApp, the approval remains active and is a potential security risk.
Will revoking affect my LP positions or staking?
No effect on existing positions. Revoking only prevents the contract from spending more of your tokens โ active LP positions, staking, and yield farming continue as normal. Your next interaction with that DApp will require a new approval.
What is an unlimited approval and is it dangerous?
An unlimited approval lets a smart contract spend any amount of your tokens without restriction. Most DApps request unlimited approvals by default to save users gas on future transactions. The risk: if that contract gets hacked or exploited, all your approved tokens can be drained in a single transaction. Revoke unlimited approvals from protocols you no longer use.
Do I need to connect my wallet to check approvals?
No. Just enter a wallet address (0x...) to view all approvals โ no wallet connection or signing required. You only need to connect your wallet when you want to revoke.
After revoking, will DApps still work normally?
Yes, DApps continue working normally, but your next interaction will require a new approval. For example, after revoking a Uniswap approval, the next swap will include an approve step before executing โ this is expected behavior and only takes a few seconds.
Can revoking approvals recover already-lost tokens?
No. Revoking only prevents further losses โ it cannot restore assets already drained. If you were hacked, you can message Airdrop101 to investigate the root cause, protect your other wallets, and explore recovery of any remaining assets.
ETH deposited to my wallet gets swept immediately โ can revoking help?
This usually means your seed phrase is compromised and a hacker installed a sweeper bot โ revoking approvals won't fix this. You can message Airdrop101 for a wallet analysis, guidance on protecting remaining assets, and recovery support if there's still an opportunity.
