Token Approvals Explained on Linea
Why token approvals matter, what they authorize, and how to review them responsibly.
Why this matters on Linea
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.
Linea is an Ethereum scaling network with its own balances, applications and token representations.
Linea is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Linea 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.
Linea: what to pay attention to
- Security: Use trusted interfaces and verify transaction details before signing.
- Assets and tokens: Verify the token contract on Linea before moving it.
- Costs: Evaluate network gas together with any bridge or liquidity costs.
A Linea checklist for this topic
- Verify the contract address on Linea from an independent source rather than a ticker or a logo.
- Read what a Linea transaction or signature request actually authorizes before approving it.
- Treat unexpected tokens or links that appear in a Linea wallet as untrusted until verified.
- Review and revoke permissions you no longer use on Linea, especially unlimited approvals.
