Token Approvals Explained on Fantom
Why token approvals matter, what they authorize, and how to review them responsibly.
Why this matters on Fantom
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.
Fantom provides an EVM-compatible environment with its own balances and token contracts.
Fantom 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 Fantom may simply be sitting on a different network.
Fantom: what to pay attention to
- Security: Check the network and contract before interacting with unfamiliar assets.
- Assets and tokens: Verify the token contract on the selected Fantom network.
- Costs: Compare network costs with route and liquidity costs.
