This article was first published in March 2022 and summarizes more than 70 projects that have supported or will support zkSync.

In recent months, the zkSync ecosystem has also appeared (or expanded from other networks) DEX protocol SyncSwap, lending protocol Nexon Finance, Play-to-Earn game MiniMiniDungeon, game Crypto Maze, DeFi protocol Trustless, cross-chain Web3 At the same time, the blockchain security service platform Go+ Security and Verilog Solutions have also begun to provide security services and audit services for projects on the zkSync platform.

At the same time, zkSync released the V2 testnet update in June, adding the account abstraction function, which allows contracts instead of just external accounts to initiate Ethereum transactions. This function removes functions such as signature verification, Gas payment and replay protection from The core protocol is transferred to the Ethereum virtual machine, so that the contract itself will have verification and gas fee payment logic that miners need to verify. In addition, the new version enables Layer 2 to Layer 1 real-time messaging.

, in the short term, Optimistic Rollups may win in general EVM calculations, and ZK Rollups may win in simple payments, transactions, and other application-specific use cases, but in the medium and long term, as ZK-SNARK As the technology improves, ZK Rollups will win in all use cases.

zkSync developed by Matter Labs, as an expansion solution based on the ZK Rollups architecture, has launched the 1.0 mainnet mainly focusing on payment purposes and the general 2.0 testnet fully compatible with EVM. In zkSync 2.0, the L2 state is divided into zkRollup and zkPorter with off-chain data availability, both composable and interoperable. This month, zkSync also upgraded its 2.0 portal, which supports payment of network fees with any token, which greatly improves user flexibility.

The zkSync expansion solution has not only won the favor of a large amount of capital. As of November last year, Matter Labs has raised $58 million from a16z, Union Square Ventures, and Placeholder. Of course, it also attracts other ecological projects or infrastructure.

However, since zkSync 1.0 is not yet compatible with EVM, there are only about 10 projects that have supported or integrated zkSync, most of which are wallet and payment gateway projects, including Argent, ZigZag, Ramp Network, Banxa, wallet Numio, imToken, Orbiter Finance, MathWallet, payment gateway Sprintcheckout, The Graph. The AMM protocol Mute.io has launched the zkSync 2.0 test network. In addition, it is currently possible to participate in Gitcoin donation activities through zkSync. It is expected that zkSync 2.0 will promote ecological development in the field of DeFi and NFT after it is officially launched.

Fully open Layer2 account registration, now anyone can access its Ethereum zkSync network Layer2 wallet.

Numio Numio (already live)

It is a Layer2 mobile wallet application based on Ethereum and zkSync, which also integrates cryptocurrency purchase and exchange functions. According to the roadmap, Numio will later integrate other Layer2 solutions, as well as integrate NFT and DeFi functions, including mining and lending.

In addition, zkSync also supports logging in to zkSync through Wallet Connect or Ethereum wallets MetaMask, Formatic, Trezor and Ledger on its official wallet page, and then MetaMask, 1inch Wallet and MyKey will also support zkSync.

At present, a total of 15 cross-chain solutions or bridges have or will integrate zkSync, among which ZigZag and Orbiter Finance already support the cross-chain between zkSync and other blockchains.

ZigZagZigZag Bridge (already live)

Exchange is an order book DEX based on ZK Rollup. In addition, the ZigZag bridge function also supports asset exchange between Ethereum and zkSync, and a cross-chain bridge from zkSync to Polygon is also launched. However, the zkSync-Polygon cross-chain bridge is still in alpha mode and has not been integrated into the UI page. Currently, it can only be sent manually to address.

Ferrum Network

Via Protocol 

Via Protocol, will integrate its product suite with zkSync expansion solutions, including traditional pledge, VIP pledge, NFT pledge, multi-asset pledge, LP pledge, etc., and will also integrate its cross-chain aggregator InfinitySwap in zkSync.

According to the official website, Via.Exchange’s partners include NEAR, Biconomy, etc., and previously completed a $1.2 million pre-seed roundfinancingfinancing

, investors include Ravikant Capital and Shima Capital, etc.

Other bridge infrastructures that are preparing or are integrating zkSync include Automata Network, Connext, Celer, Composable Finance, Poly Network, Multichain, Nomad (a cross-chain communication solution, the token bridge has been launched on Ethereum and Moonbeam) and deBridge, which will not be discussed here. Let me introduce you further.

In addition, according to the content updated by zkSync last month, the bridges supporting zkSync will also include DAI Wormhole (built by Maker, which will allow users to transfer DAI between Layer2), Hop Exchange, and LayerZero.

Payment/Gateway/CEX (5)

Banxa, MoonPay, Ramp Network, Simplex, and UTORG, which provide fiat-to-crypto gateway solutions, will provide the ability to purchase cryptocurrencies directly on zkSync through various payment methods. Among them, Banxa and Ramp Network have already begun to support zkSync.SprintcheckoutLayer2 payment gateway based on ZkSync

is also live. Sprintcheckout launched a payment gateway for merchants that allows merchant customers to pay via ZkSync, accepting ETH or ERC-20 tokens as payment. There is no fee charged by the customer and a 0.5% Sprintcheckout transaction fee and ZkSync fee charged by the merchant on each transaction.LayerSwapIn addition, projects that can transfer cryptocurrencies from CEX to Layer 2

Transferring ETH or USDC from Coinbase, FTX, Binance, OKX, KuCoin, and Huobi to zkSync is also supported.

Block Explorer (3)

Matter Labs has officially launched zkSync block explorer and analysis platform zkScan before. In addition, Matter Labs also stated that it will also ensure that users can access zkSync data through Etherscan and Blockscout in the future.

NFT/ game

NFT/ game

• Since zkSync 1.0 is not EVM compatible, the only NFT functionality currently available is the built-in wallet minting functionality. Other NFT projects, games or marketplaces exploring building on zkSync 2.0 include:

• Mint Square (an NFT market based on Layer 2 ZK Rollup, which has previously supported NFT minting on the StarkNet Goerli test network, and will support zkSync 2.0 later)

• OpenStars (P2E space strategy game)

Other ecological projects exploring building on zkSync include Snapshot, Aragon that allows anyone to create and manage decentralized organizations, Forward Protocol, and clr.fund.

clr.fund is a Gnosis Chain-based quadratic financing protocol that effectively allocates matching funds to public goods in the Ethereum ecosystem. It combines quadratic financing, zk-SNARKs, minimized anti-collusion infrastructure (MACI) and Sybil attacks, working towards more democratization and greater funding of public goods.

zkSync has previously confirmed the shift to decentralization and publishing. In the latest update, zkSync stated that the current zkSync is completely run by the server of the zkSync team and is centralized. It is currently close to balance of payments. Of course, it will be adjusted according to the gas fee from time to time. its costs. However, zkSync will move towards decentralization and currency issuance in the future, and the current priority is to solve the scalability of Ethereum.

When zkSync is completely decentralized, an independent consensus mechanism and two different roles will be introduced. Among them, the verifier needs to pledge tokens, and the other role is Guardian, that is, the majority of nominated verifiers who pledge their token shares. part holders.

Risk warning: Most of the native projects based on zkSync are in the testing stage, and the project team and security audit information are not disclosed too much, so users are reminded to identify risks by themselves.
