Approval is separate from a transfer
Many token applications ask a wallet to approve a contract to spend up to a stated amount. The approval transaction does not necessarily move tokens immediately; it changes what the contract may request later. Read the spender address, token and allowance before signing.
Review by network
Allowances are recorded on a specific network and token contract. A review on one chain does not prove that permissions on another chain are safe. Use a reputable block explorer or allowance tool, compare the contract address with the project’s official documentation and remove permissions that are no longer needed.
Keep a change record
- Record the date, network, token and spender before changing an allowance.
- Use a small allowance for a limited task when the application supports it.
- Treat an urgent message asking for a “security approval” as a phishing signal.
