Important notes

ETH on zkSync Era is not ETH on Ethereum. Both are called ETH, but each network keeps its own balance, and ETH on Ethereum cannot pay a fee on zkSync Era. To move ETH between them, use Bridge.
Add your tokens. FxWallet does not find zkSync Era tokens automatically. Search for the ones you hold or enter their contract address, and check the address on the project’s website: several tokens can share a name. See Add tokens and networks.
Approvals last until you revoke them. Approve only what a DApp needs, and revoke what you no longer use. See Token approvals.

Questions

In the help center

Which network do I choose to withdraw to FxWallet from an exchange?

zkSync Era, which some exchanges call ZKsync. In FxWallet the network is called zkSync Era: tap Receive and choose ETH on zkSync Era to copy your address. It is the same address as on Ethereum, so make sure the exchange sends on zkSync Era. See Deposit or receive crypto.

Does the ZK token pay the fees on zkSync Era?

No. FxWallet pays fees on zkSync Era in ETH. ZK is an ERC-20 token on zkSync Era, which you hold and send like any other.

Can I move my wallet from MetaMask or another zkSync Era wallet?

Yes. Import its mnemonic phrase: FxWallet derives EVM accounts on the same path as MetaMask (m/44'/60'/0'/0/n), so the addresses match. You can also import a single account by its private key, or follow an address as a watch wallet.
