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