Frequently Asked Questions
Why are unlimited token approvals dangerous?
When you approve a DEX or protocol with "unlimited" allowance, the contract can transfer that token from your wallet without additional permission. If that protocol is hacked or malicious, all approved tokens can be drained instantly.
How do I revoke an approval?
You can submit a transaction that sets the approved allowance to 0 using security tools such as Revoke.cash, Etherscan Token Approval tool, or within Rabby Wallet.
