Token Approvals Explained on BNB Smart Chain
Why token approvals matter, what they authorize, and how to review them responsibly.
Why this matters on BNB Smart Chain
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.
BNB Smart Chain is an EVM-compatible network with its own BEP-20 token representations.
BNB Smart Chain uses EVM-style addresses and token contracts, which means the same address can hold balances on several EVM networks at once. A balance that is missing on BNB Smart Chain may simply be sitting on a different network.
BNB Smart Chain: what to pay attention to
- Security: Treat unexpected tokens and unfamiliar approvals cautiously and verify contracts before interacting.
- Assets and tokens: Verify BEP-20 contracts and distinguish legitimate assets from unsolicited tokens.
- Costs: Network transaction costs are only one part of the route; compare the complete cost before moving small balances.
A BNB Smart Chain checklist for this topic
- Check the domain you are on before connecting a wallet for any BNB Smart Chain action.
- Send a small test amount first when an address or route on BNB Smart Chain is new to you.
- Verify the contract address on BNB Smart Chain from an independent source rather than a ticker or a logo.
- Read what a BNB Smart Chain transaction or signature request actually authorizes before approving it.

Network transaction costs are only one part of the route; compare the complete cost before moving small balances. On the Arbitrum side: confirm the Arbitrum token contract rather than assuming an identical ticker represents the same asset everywhere.
The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
