Common Web3 Wallet Scams on Base
Recognize common phishing, fake airdrop, malicious approval, and impersonation patterns.
Why this matters on Base
Most wallet scams create urgency: a fake reward, a security warning, or a limited-time claim. Slowing down and verifying the destination domain and contract can prevent many losses.
Base is an Ethereum Layer 2 environment with its own network balances, applications and token representations.
Base is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Base 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.
Base: what to pay attention to
- Security: Use trusted interfaces and verify destination network and token before signing.
- Assets and tokens: Verify the token contract on Base and do not rely on ticker or logo alone.
- Costs: Consider Base transaction costs together with bridge and route costs when moving small balances.
A Base checklist for this topic
- Check the domain you are on before connecting a wallet for any Base action.
- Send a small test amount first when an address or route on Base is new to you.
- Verify the contract address on Base from an independent source rather than a ticker or a logo.
- Read what a Base transaction or signature request actually authorizes before approving it.
