How to use Argent wallet for zkSync? (L2 wallet guide)

Setting Up Argent Wallet for zkSync

1. Download the latest version of the Argent mobile app from the official App Store or Google Play store. Ensure the app version supports zkSync Era, as older builds may lack compatibility with the zkEVM-based L2 network.

2. Launch the app and select “Create new wallet” or “Import existing wallet” depending on your preference. If importing, verify that your seed phrase was generated on a compatible version—Argent does not support direct import of externally generated private keys.

3. During setup, choose zkSync Era as your preferred Layer 2 network. The wallet will automatically configure its RPC endpoint and token list to align with zkSync’s ecosystem standards.

4. Confirm your wallet address is displayed with the zkSync Era network indicator—this appears as a small purple icon next to the balance section. The address remains the same across Ethereum mainnet and zkSync, thanks to Argent’s account abstraction architecture.

Depositing Assets onto zkSync

1. Tap the “Deposit” button located in the asset view screen. Select ETH or any ERC-20 token supported by zkSync Era, such as USDC.e, DAI, or WBTC.

2. Enter the amount and confirm the transaction on Ethereum mainnet. This initiates a cross-chain bridge operation handled natively by Argent’s integrated bridge interface.

3. Wait for finality confirmation—typically 15–30 minutes for ETH, longer for certain tokens due to external bridge logic. You’ll receive an in-app notification once funds appear in your zkSync balance.

4. Note that deposits are irreversible and subject to Ethereum gas fees. Argent displays real-time gas estimates before signing, helping users avoid overpayment during peak congestion.

Executing Transactions on zkSync Era

1. Navigate to the “Send” tab and input the recipient’s zkSync-compatible address. Argent validates address format and network alignment before proceeding.

2. Choose the asset and amount. The wallet calculates fee in ETH, denominated in gwei, reflecting current zkSync Era pricing—often below $0.01 for simple transfers.

3. Review transaction details including calldata size, gas limit, and estimated L1 data cost. These values are fetched live from zkSync’s API endpoints.

4. Sign using your biometric or passcode authentication. Argent leverages smart contract wallets, so all operations are routed through your deployed account contract on zkSync.

Managing Security and Recovery

1. Argent uses guardian-based recovery instead of seed phrases. Add at least one trusted contact or hardware wallet as a guardian during onboarding—this is mandatory for zkSync Era usage.

2. Guardians can co-sign critical actions like changing guardianship or withdrawing large amounts. Each guardian receives push notifications for pending requests.

3. Monitor active sessions under “Security Settings”. zkSync-specific sessions are tagged separately from Ethereum mainnet ones, allowing granular control.

4. Disable unused dApps via the “Connected Apps” section. Argent maintains separate permission sets per chain, ensuring zkSync permissions do not affect mainnet access.

Frequently Asked Questions

Q: Can I use my existing Argent wallet address on zkSync without creating a new one?Yes. Argent deploys the same account contract address on zkSync Era as on Ethereum mainnet, preserving identity continuity across layers.

Q: Why does Argent require guardians for zkSync but not for basic Ethereum transactions?zkSync Era enforces stricter account abstraction rules for wallet initialization. Guardian setup is part of Argent’s compliance with zkSync’s security model for smart contract wallets.

Q: Are NFTs supported on zkSync via Argent?Argent currently displays only ERC-721 and ERC-1155 tokens minted directly on zkSync Era. Cross-layer NFT bridging is unsupported in the wallet interface.

Q: What happens if I lose access to both my device and guardians?Recovery becomes impossible. Argent does not store private keys or guardianship data centrally. Users must re-establish guardianship before losing all access points.
