zkSync 1.0 launched to mainnet in June 2020. It enabled fast, cheap, and scalable transactions. Here’s a list of things to do right now on zkSync 1.0 Mainnet.
Listing of an application on this post does not represent an endorsement by Matter Labs. Please do your own research and exercise caution prior to using any application. Always read signatures prior to signing a message.
First, move funds into zkSync via a bridge, gateway, or an exchange. If funds are being sent to a new zkSync account, make sure to send enough funds to cover the single-time account activation fee (see #2 below). Pease read this tutorial for instructions on using the zkSync native bridge,
Bridge: A bridge allows users to transfer assets between blockchains. The zkSync native bridge supports ERC-20 token transfers between Ethereum Mainnet and zkSync. Layerswap is a solution that allows users to deposit funds from a centralized exchange into zkSync.
Gateway: A gateway is a fiat on/off ramp that allows users to purchase crypto with fiat using a credit card or bank account. The gateways listed below support certain assets on zkSync. Gateways require Know Your Customer (KYC) credentials.
Exchange: Sending funds from an exchange that supports zkSync is the lowest-cost option because it avoids the need to bridge. The following exchanges support certain assets on zkSync. Please verify with an exchange prior to depositing or withdrawing funds.
When making a transaction for the first time, users will be prompted activate their account. This is a single-time operation and the process will vary based on the application used. The transfer tool within zkSync can be used to activate an account. To activate an account, follow the steps below as prompted.
Step 1: Go to the transfer tool here and connect a wallet.
Step 2: Paste in a transfer to address. You can even transfer to yourself.
Step 3: Set the transfer amount.
Step 4: Click “Authorize Sign Account Activation” and sign the first signature.
Step 5: Click “Sign Account Activation” and sign the second signature. This signature registers a key pair (ChangePubKey) for the zkSync wallet.
Step 6: Click “Proceed to Send on zkSync” and sign the third and final signature. This signature includes a gas fee for the Account Activation Fee and the Transfer Fee.
That’s it! There will be two transactions shown in zkscan. The first transaction type will display “ChangePubKey.” The second transaction type will display “Transfer.” Once the transaction is verified, the wallet is activated and ready for use.
zkSync 1.0 has native support for minting, transferring, and swapping NFTs. The minting process involves the uploading of content to IPFS in order to obtain a Content Identifier (CID). A step-by-step tutorial for minting an NFT on zkSync is linked here. Pinata Cloud is a pinning service that allows users to host files on a private IPFS node.
An NFT will be visible and can be transferred after the transaction reaches a verified status. This is represented by two green checkmarks and can take up to 7 hours after the minting process is complete. NFTs can also be withdrawn from zkSync to L1, but cannot be bridged from L1 to zkSync at this time.
Metadata Not Found: If a “metadata not found” error is encountered, try pinning the IPFS file. Make sure the CID of the metadata json file was submitted, not the CID of the image. Lastly, give the IPFS network some time to host the file across peers.
OpenSky is front end tool for minting NFTs on zkSync 1.0. It was created by community member neoc#0001. The tool automates the creation of the metadata json file needed to embed the preview image in the NFT. Users simply upload an image and provide a few optional details to mint.
Here’s how to mint an NFT using OpenSky.
Warning: OpenSky was created by a community member and is no longer being maintained. Errors may occur.
Step 1: Visit the tool here.
Step 2: Connect a wallet.
Step 3: Click on the “Mint” tab.
Step 4: Fill in the details. Everything is optional except for uploading an image.
Step 5: Click on “Mint.”
Step 6: Review and approve the signature. The gas fee for minting will be shown in the signature. That’s it! The status of the NFT will be displayed in the “Profile” tab.
zkCheckout is a tool for creating payment links on zkSync. The links can be used as payable invoices or requests for payment. zkCheckout can also be used to create a batch of transactions. This allows a sender to transfer tokens to up to 20 wallets using a single transaction. Developers can use the zkCheckout SDK to implement payments via zkSync onto any website.

Argent is a smart wallet managed by a smart contract instead of a private key. There is no mnemonic phrase. Rather, other wallets can be added as guardians that have the authority to approve transactions and initiate wallet recovery. Argent has taken the lead on bringing DeFi to L2 by integrating with zkSync. Users now have access to DeFi at a fraction of the cost compared to Ethereum Mainnet. Please read this article for step-by-step instructions for creating an Argent wallet.
Argent wallets created after July 2021 automatically claim a zkSync address during the wallet creation process. A zkSync address will need to be manually claimed for Argent wallets created before July 2021. Claiming a zkSync address involves an Ethereum Mainnet transaction and will incur a network fee. Please read this article for instructions on how to claim a zkSync address for accounts created before July 2021.

Here’s a zkSync ecosystem tracker to help track what’s available:
Matter Labs is currently working diligently towards zkSync 2.0, an EVM-compatible zkRollup. You can learn more on testing zkSync 2.0 here.
