Wallet Security Basics for Everyday Web3 on zkSync
A straightforward security checklist covering approvals, contract addresses, signing, and backups.
Why this matters on zkSync
Good wallet security is mostly about reducing avoidable signing mistakes. A read-only balance check should never require a seed phrase, and unfamiliar approvals deserve extra scrutiny.
zkSync is an Ethereum scaling ecosystem with its own network context and token representations.
zkSync is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on zkSync 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.
zkSync: what to pay attention to
- Security: Check the active network, contract and destination before signing.
- Assets and tokens: Verify the asset contract on zkSync before assuming it matches another network.
- Costs: Compare network fees with bridge and liquidity costs for the complete route.
A zkSync checklist for this topic
- Read what a zkSync transaction or signature request actually authorizes before approving it.
- Treat unexpected tokens or links that appear in a zkSync wallet as untrusted until verified.
- Review and revoke permissions you no longer use on zkSync, especially unlimited approvals.
- Check the domain you are on before connecting a wallet for any zkSync action.
Bridge from zkSync
Compare network fees with bridge and liquidity costs for the complete route. On the Linea side: verify the token contract on Linea before moving it.
The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
