The mainstream protocols on Ethereum, from Uniswap to OpenSea, have promoted a surge in the amount of interaction on the Ethereum chain in the past year, but for ordinary users, it has made the experience worse. When I borrow $300 in Aave-v1 in order to complete the task of Rabbithole, it may cost $500 in gas fees alone at some point.

Matter Labs, who built zkSync, proposes an equally secure and much cheaper alternativezkSync 2.0——It has been launched on the Goerli test network of Ethereum for users to explore and conduct stress tests. The v1 version of zkSync went live on the Ethereum mainnet in mid-2020, processing millions of transactions securely and almost trustlessly, but at a fraction of the transaction cost. The cryptographic principles behind this exciting innovation are known as Zero Knowledge Proofs, which we explore in Part II. Having said that, this solution to improving scalability is called Zero Knowledge Rollups (ZKRs). Let's take a look at what ZKR brings to those who are unwilling to spend $50 Gas fee to transfer $20 ETH.

Test on the Goerli testnet - You can switch to the Goerli testnet in MetaMask's advanced settings or in the Rainbow wallet's settings.

How to get Goerli's test coinszkPortalYou can also choose to seek help from almighty netizens, or connectMudit(wallet version 2.0) to get a small amount of tokens for testing. These tokens have no value, and their faucet seems to be "dry" recently. You can also use
In short, you can search for many related methods.
Mute Switch
Mute SwitchA user on zkSync's Discord was kind enough to offer me test tokens, but the truth is that this person just wanted to know my wallet address.
zkScan
It is a full-featured automated market maker (AMM), providing an overview of L2 assets and the functions that AMMs should have: token trading, liquidity provision (LP) and transaction fee mining - users can pledge their LP tokens Coins to obtain transaction fee incentives. The user experience design of Mute Switch is similar to that of Uniswap and SushiSwap. If you want to make money from it, you can wait until its mainnet is released before interacting.
Inspired by Etherscan, the design of zkScan is not only simple and clear, but also more practical than Etherscan: you can see real-time block information, as well as the average block time, total transaction volume, total number of blocks, and total wallets Clearly displayed information such as addresses. At the same time, zkScan also provides the real-time price and market value of Ethereum, as well as its historical price trend.
Onramps (deposit)
"Funding" is still the key step that people need to take to enter the cryptocurrency world. Although it is controversial, this step actually gives people the power to choose the way of consumption. Banxa, Ramp Network, UTORG, and MoonPay are all listed by Matter Labs as zkSync-compatible applications. In the future, you can directly convert legal currency into tokens on L2 to save gas fees on L1. Users only need to link bank account information and wait for a period of time to complete the "deposit".
zkEVM protocol development
The health of the ecosystem depends on "nutrition" + diversity. The blockchain relies on the existence of the protocol to inject vitality into it. A large number of cooperation, experimentation and integration will surely bring beneficial chemical reactions.
zkSync 2.0 is the first EVM-compatible ZKR, built on top of zkEVM. In line with the principle of giving priority to Solidity, Matter Labs will develop Zinc, the native framework of zkSync, after the Solidity version is released.
If you are a developer interested in ecological exploration, you can check out the developer guidance document.zkSync DiscordEthereum's main network contains dozens of basic DeFi protocols, hundreds of NFT contracts, and thousands of test contracts, including Aave, Chainlink, ENS, Graph, Lens, Mirror, Orca, Rabbithole, Tally, Uniswap, Yearn, Zora and so on. If you want to port some protocols to zkEVM, please contact the existing team or at

18 and 41 times cheaper.
Checkout
Wallet v1, developed within Onramps, provides a native mainnet bridge that allows users to transfer funds from Ethereum L1 to zkSync L2, and we expect to have the ability to view token balances and transfer between wallets in the future.
CheckoutIf you donated in the past 4 rounds of Gitcoin Grant, there is a high probability that you made the transfer through zkSync, and 98% of the transfers were made through zkSync’s rollup scheme. cost savings.SDKAllows you to transfer funds to 20 different recipients at the same time, using
You can add an additional 70 customizable transactions at the same time.
Funding programs around the world can use Checkout to develop near-free, instant and secure payment channels, improving payment efficiency and transparency.
Foundry DNA
Wallet v1 gives you the opportunity to mint your own Digital Native Asset (DNA) NFT, provided you provide a unique content identifier addressed by IPFS.I would like to take this opportunity to show you what XEDRA wrote, and is the most exhaustive I've read to create on Polygonmusic DNA
guide. This guide also applies to any DNA and will remove any concerns you may have about your first experience. While there are concerns about the security and ownership of funds on Polygon, Polygon is still one of the lowest cost and most scalable options.
Of course, it must be admitted that any technology is not foolproof in the face of pirated technology that is also constantly "introducing the old and bringing forth the new", so please be careful not to play too big.
ZigZag
OrbiterCurrently supports cross-chain transfers of ETH and USDC between Ethereum, Arbitrum, Optimism, Polygon and zkSync. There is nothing more to say, cross-chain interoperability is cool, cross-chain bridges may be risky, I hope you can research it yourself.

zkDAO
On January 6, 2022, Matter Labs submitted a proposal to BitDAOproposalproposal, regarding BitDAO for "Accelerating mass adoption of cryptocurrencies and achieving financial autonomy
” Invested $200 million in zkSync. The proposal is currently passed. The $200 million investment will be split into 5 tranches of $40 million each, with subsequent tranches contingent on milestones and governance votes.
The allocation details are as follows:
1) Donation: 7.5% — Funding public goods and infrastructure development
Additional tools for L1 to L2 migration
(Traceable) Funding Actions, Submission of Proposals Required
zkSync native tool to support ZKR applications
2) Security/Audit: 7.5% — Support the development of high security instances and frameworks
Reduce the complexity of L1 to L2 migration
Create consensus and build common security standards
Events, workshops, hackathons between security experts and community members
3) Strategic investment: 70% — Use industry knowledge to deploy strategic investment
Help the development of projects in vertical fields through guidance + training + community support. Including DeFi, NFT, Gaming, Payment, Privacy, Interoperability, Oracle, Data Management, Data Analysis, File Storage, Airdrop, DAO, Digital Identity and Social
Once the security of the tool is mature, funds will be invested, liquidity will be added, and pledges will be made, and the proceeds will be reinvested
4) R&D: 5%
Research on zero-knowledge encryption + related hardware fields
5) Education: 5%
Developer Training on Scalability: Security, Compute, Data Availability
