Token Approvals Explained on Sui
Why token approvals matter, what they authorize, and how to review them responsibly.
Why this matters on Sui
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.
Sui uses an object-centric model that differs from the account and token conventions of EVM networks.
Sui does not follow standard EVM conventions. Address formats, token identifiers and approval mechanics differ, so EVM-oriented checklists and tools should only be applied to Sui after confirming they are supported.
Sui: what to pay attention to
- Security: Review transaction effects carefully and use trusted wallet interfaces.
- Assets and tokens: Verify the network-specific asset and object details rather than applying EVM assumptions.
- Costs: Consider network transaction costs and route-specific costs when evaluating small balances.
A Sui checklist for this topic
- Verify the contract address on Sui from an independent source rather than a ticker or a logo.
- Read what a Sui transaction or signature request actually authorizes before approving it.
- Treat unexpected tokens or links that appear in a Sui wallet as untrusted until verified.
- Review and revoke permissions you no longer use on Sui, especially unlimited approvals.
