Token Approvals
Learn spenders, approval limits, persistent permissions and revocation with practical security checks and on-chain verification guidance.
Core concept
Token Approvals should be understood in the broader wallet and on-chain context. Identify the asset, network and controlling address, then determine whether the next step creates a connection, signature, approval or transaction. A clear model of spenders, approval limits, persistent permissions and revocation makes it easier to separate interface messages from actual on-chain state.

Operating sequence
For spenders, approval limits, persistent permissions and revocation, use a deliberate sequence: verify the entry point, confirm the network, check the address or contract, review the exact request, then submit. For asset movement, also verify the amount, fee and transaction hash. For DApps, distinguish connection, message signatures, transaction signatures and token approvals because they create different permissions.

Common mistakes and verification
Common mistakes include using the wrong network, copying a bad address, ignoring token contracts, treating pending transactions as failures, or accepting an unclear approval. Troubleshoot spenders, approval limits, persistent permissions and revocation with verifiable data such as transaction hashes, block heights, address history and contract addresses instead of relying only on interface messages.

Security and risk boundary
Seed phrases and private keys should remain under the user’s control. Official support should not request them, and verification codes should never be shared. Third-party DApps, smart contracts and network services can introduce risk. Because confirmed transactions are usually not reversible by the wallet alone, pre-signing checks are essential.
