Fake Airdrops: How to Stay Safe on Optimism
How fraudulent airdrops use urgency and unfamiliar contracts to trick wallet users.
Why this matters on Optimism
An unsolicited token or airdrop is not a free invitation to interact. If claiming requires a suspicious approval or a transaction with unclear effects, do not sign it.
Optimism is an Ethereum Layer 2 environment with its own transaction and asset context.
Optimism is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Optimism 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.
Optimism: what to pay attention to
- Security: Check network, recipient, contract and transaction details before signing.
- Assets and tokens: Verify the Optimism contract address for the asset you intend to move.
- Costs: Compare network gas with bridge and route costs, especially for low-value balances.
A Optimism checklist for this topic
- Read what a Optimism transaction or signature request actually authorizes before approving it.
- Treat unexpected tokens or links that appear in a Optimism wallet as untrusted until verified.
- Review and revoke permissions you no longer use on Optimism, especially unlimited approvals.
- Check the domain you are on before connecting a wallet for any Optimism action.
Bridge from Optimism
Compare network gas with bridge and route costs, especially for low-value balances. On the Avalanche side: verify the asset representation and contract on the selected Avalanche network.
The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
