Detailed explanation of interaction on ZK series Layer2 chain

The huge wealth effect brought by the Arbitrum airdrop made the community users who received it revel in it, and also made the users who missed it feel annoyed, so they began to look for the next project that has not issued coins, hoping to be eligible for the next airdrop. Of the four former layer 2 kings: only two are left who have not announced airdrops. The market weight of Optimism and Arbitrum in the Layer2 ecosystem is already obvious. With the arrival of Layer2 summer, zkSync, Starknet and Scroll, the unreleased currency projects in the same track as Layer2, naturally have high hopes. This article will focus on sorting out each L2 interaction process and explaining the steps in detail. We look forward to the prosperity of industry users when L2 Summer arrives.

01. scroll interactive tutorial

1. First, get the Ethereum Goerli testnet token ETH. goerlifaucet.com/, goerli-faucet.pk910.de

Note that generally an account can only receive 0.1 TETH within 24 hours.

However, currently due to the impact of the Arbitrum airdrop, a large number of users choose to interact with addresses on many test networks, resulting in a tight quota for faucet collection. However, Layerzero launched testnetbridge to solve the problem of insufficient TETH quota. You can exchange mainnet ETH for TETH at the website as follows:

https://testnetbridge.com/

2. After receiving the test tokens, go to the Scroll official website and add Scroll Testnnetwork to Metamask.

https://scroll.io/alpha

After adding it, use the Scroll official cross-chain bridge to cross the TETH of the ETH Goerli test network to the Scroll Testnetwork

After crossing to Scroll, select Uniswap that has been integrated into Scroll to interact, including swap and liquidity staking.

The token contract query address on Scroll Uniswap is: blockscout.scroll.io/tokens

(1) Swap can conduct multiple exchanges every day to increase the number of interactions

(2) Liquidity staking requires several more attempts due to the lag on the Scroll test network.

zksync ERA interactive tutorial

After Zksync era was launched on the main network on March 24, the tokens received by faucet in the past could only be used to interact with the Lite test network. Currently, era interaction needs to connect to the zksync main network and use official or third-party bridges for cross-chain interaction.

After the cross-chain is completed, you can visit syncswap for regular interaction. Of course, you can also choose to interact on other DAPPs, or you can choose to mint related NFTs on the official website to achieve interaction.

Of course, you can also choose to interact on the lending agreement, but currently nexon has not been deployed on the zksync era mainnet. If you want to interact, you still need to use TETH test tokens.

Starknet interaction

1. First of all, because of the account abstraction and the fact that Starknet itself is ZKVM written by Cario, the ArgentX plug-in wallet needs to be installed. However, considering the centralization issue of ArgentX, it is recommended that the interaction can be carried out in small amounts and in batches.

The ArgentX wallet needs to be added to the extension in the Google store and set your own wallet password (it is recommended to create your own wallet and try not to import other wallet mnemonics or private keys into ArgentX)

2. After creating the ArgentX wallet, transfer ETH through the Starknet official cross-chain bridge.

https://starkgate.starknet.io/, complete the interaction by accessing different types of Dapp, mainly completing Defi swap and liquidity staking, you can also choose to purchase NFT, etc. to complete the interaction. Let’s take 10kswap as an example.

Of course, there are many types of Pool pledge pools, and the gameplay between different Swaps is also different. Users can interact with different Defi applications according to their own circumstances. The main purpose is to obtain ecological incentives for the community from the project. At the same time, users should also pay attention to the current The number of people interacting has increased sharply, and the speed of network transfers or transaction processing has been relatively slow. Each transaction has even been delayed to 20-30 minutes. If it is transferred from L2 to the L1 mainnet, it will take even longer.

Summarize

Although simple and crude airdrops can cause user fanaticism and market enthusiasm to surge in the short term, truly high-quality projects have long known that simple airdrops will not substantially help the growth of the project. We don’t know whether airdrops will be replaced, but in the early stage The incentive policy for seed users and the long-term planning and healthy development of the project are the cornerstone and foundation of truly building a good web3. In the web3 industry with gradually strengthening financial attributes and outstanding advantages, we hope that airdrops will attract users, but users will be frustrated by the project. Unique charm and long-term stay together.
