What it means
Approvals are common in swaps and DeFi apps.
Why it matters
Risky or unlimited approvals can expose funds if a contract is malicious or compromised.
Common mistake
Do not treat Token Approval as a universal rule. Exchanges, wallets and card apps may use the same term differently, especially around limits, fees, networks and account restrictions.
User action
Before relying on this term, check the provider's official help page, fee schedule or product terms. If funds are involved, test with a small amount first and keep a record of the transaction or setting.
