Token Approvals Explained on Metis
Why token approvals matter, what they authorize, and how to review them responsibly.
Why this matters on Metis
An approval gives a contract permission to spend a specified token balance under the rules of that approval. Reviewing old approvals can reduce exposure to applications you no longer use.
Metis is an Ethereum scaling environment with its own network and token representations.
Metis is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Metis as separate token contracts, so a balance seen on one network cannot be assumed to exist, or to be redeemable at the same value, on the other.
Metis: what to pay attention to
- Security: Confirm network and transaction details before signing.
- Assets and tokens: Verify the token contract on Metis.
- Costs: Compare L2 gas with bridge and liquidity costs.
A Metis checklist for this topic
- Check the domain you are on before connecting a wallet for any Metis action.
- Send a small test amount first when an address or route on Metis is new to you.
- Verify the contract address on Metis from an independent source rather than a ticker or a logo.
- Read what a Metis transaction or signature request actually authorizes before approving it.
