Layer 2 Tutorial Series 1: Teach you to use several major Layer 2 applications

The soaring price of Ethereum and the continuous increase of on-chain activities caused by DeFi have made the gas fees denominated in both legal currency and Ethereum continue to hit new highs. This has also sparked heated discussions on Ethereum 2.0 and Layer 2 (L2). The sheer number of L2 protocols popping up quickly can be dizzying. There are actually applications, and the L2 applications that users can use are still a small number. The usage of some L2 protocols with practical applications is introduced below.

 

zkSync（zkRollup）

 

zkSync was created by Matter Labs based on ZK Rollup and now has Gitcoin Grants donations< /a>, Curve testnet, and payments for zkSync.

 

Step 1: Login to zkSync

 

First log in to the official website: https://wallet.zksync.io //, click on the link to the Ethereum mainnet wallet.

 

 

2. Choose to connect wallet and address.

 

 

The address signature is required during the login process.

 

3. After the login is complete, select deposit and unlock the token before transferring to the L2 layer.

 

 

4. After the deposit is completed, the balance will be displayed in the wallet.

 

5. In the transfer interface, you can see all transfer records.

 

It is worth mentioning that zkSync now provides the zkLink function, which can be created by the user's own design amount and token type. Similar to "QR code collection", users who click on the link can see the payment requirements and choose to pay.

Like other L2 protocols, tokens moved to L2 are transferred back to L1 layer, which is the Ethereum master The service fee of the network and the lock period are longer (affected by the congestion of the Ethereum network).

After digging into zkSync’s wallet, users can use it as a way to donate to Gitcoin, thereby avoiding high Gas impact.

 

xDAI (side chain)

 

Users who have heard of the recently popular blockchain game Dark Forest or the decentralized derivatives trading platform Perpetual Protocol should know about xDAI. As an EVM (Ethereum Virtual Machine) sidechain of Ethereum, xDAI also has practical use cases such as chain games and DEX.

 

The xDAI Bridge is introduced below. Through the following operations, users can directly transfer from the A address that already holds xDAI to the newly created Game or transaction address B sends xDAI without repeated operations.

 

1. Log in to https://bridge.xdaichain.com/ and connect to the Ethereum wallet Metamask.

 

 

single unlock) or Infinite Tx Unlock (unlimited unlock).

 

3. Click "Advanced", add the address that accepts xDAI and the amount to transfer from Dai to xDai. Press Unlock.

 

4. Confirm in MetaMask Unlock transactions.

 

 

5. Click transfer and confirm the transaction .

 

 

6. Once the transfer is successful, the user You will receive a series of notifications, the last step is "Transfer Complete".

 

7. The above method can only convert DAI to xDAI across accounts, and convert all other ERC20 tokens Transfer to the xDAI chain and use omni.xdaichain.

Matic Network (Plasma)

 

Other L2 protocols that have been put into use include Matic Network (Plasma), which consists of Polychain, Polymarket, a prediction market platform invested by 1confirmation and ParaFi, has already used the Matic protocol on its platform to reduce transaction fees on the Ethereum chain. Since Polymarket directly integrates Matic, users do not need additional operations. The NFT game Aavegotchi recently announced the delayed launch of the mainnet, and said that it will consider Matic Network as an L2 solution.
