"Escape from Ethereum" seems to be the slogan of many users in the market, and the upgraded Ethereum has not brought you a better experience.
Since the deployment of EIP-1559 on Ethereum, the gas fee on Ethereum has only been limited to a certain range to avoid sharp rises and falls, but it has not met the expectations before deployment, that is, the gas fee has been reduced.
In addition to the soaring gas fees caused by the popularity of NFT some time ago, the experience of many current applications on the Ethereum public chain is not good, such as chain games, such as DeFi, etc., and the characteristics of these tracks are destined to attract more and more users. The more users settle in, the load on Ethereum is undoubtedly increasing. Therefore, it is no wonder that many developers and users are interested in quitting.
There are two main ways to "escape from Ethereum".
One is that what has already happened is to choose other public chains. For example, Solana, Avalanche Protocol, Polygon, etc., which are quite popular this year, are fast, gas fees are cheap, and the ecology is also developing well. Ethereum Evm machines have also been deployed. Developers and users on the original Ethereum can realize unlimited These public chains also have considerable development opportunities this year.
The other way is the transition from ETH to ETH2.0 earlier, that is, the Layer 2 solution. Many old users of Ethereum are more accustomed to activities on Ethereum considering their feelings and security, so Layer 2 is undoubtedly a better choice. With the temporary cooling of other public chains, the concept of Layer 2 seems to have entered the initial stage of explosion recently.
The purpose of Layer 2 is to move on-chain calculations to off-chain. The idea of the model is to put all complex calculation and transaction processes off-chain, and finally only store the results on the chain, saving transaction costs and time, thereby improving the transaction experience. At present, Ethereum’s Layer 2 expansion solutions generally include technical expansion solutions such as side chains, state channels (State Channel), Plasma, Rollup (ZK Rollup and Optimistic rollup), and Validium.
The reason why the next explosive segment may be the Layer 2 public chain track is that Arbitrum’s mainnet public beta version Arbitrum One has been open to all users for only 2 weeks. 1.5 billion US dollars of encrypted assets are on the chain, while the total locked value (TVL) of the entire Layer2 sector is only 2.2 billion US dollars, and Arbitrum accounts for 68%, which undoubtedly makes some sensitive people imagine that "this may be just the beginning ""It seems that the currency has not been issued yet" "Is it possible to have an airdrop"?
You should know that the official website of Arbitrum currently does not provide information on the application development team, and multiple third-party data platforms are also prompting that the application does not have a security audit report, just because he was named by the Ethereum official, many Bold users can't wait to leave their footprints on Arbitrum, hoping to get an airdrop opportunity later.
In addition, Optimism, another Layer 2 expansion solution, has also attracted the attention of the market.
Before Arbitrum, Optimism was known as the most influential Layer 2 solution. Optimism, formerly known as Plasma Group, is the development team behind the Optimistic Rollup extension technology. Rollup is a smart contract on Ethereum that connects the Ethereum main chain and L2. Rollup receives transaction data from the Ethereum main chain, sends it to L2 for calculation, and then receives the result of L2 calculation.
At present, its overall performance is also quite good. The cumulative transaction volume has exceeded 1.59 million times, and the number of user addresses has exceeded 70,000.
In addition, the related currencies of other Layer2 sections are also worth noting, side chain: matic/loom, Plasma: omg/leverJ (unissued currency), ZK Rollup: dydx/lrc/zks/hez/zkSync (unissued currency , focus on airdrop objects)/Aztec (unissued coins), Optimistic rollup: hbt/Arbitrum, Optimism (neither have issued coins, focus on airdrop objects), Validium/StarkEx: dydx/dvf/Sorare, ImmutableX (unissued coins) , others: celr/skl/nii, etc.
At present, the Layer 2 sector is very likely to become the next explosive sector, especially in the current situation where the market sector rotates so fast, friends who want to airdrop can interact with it, and attach the interactive tutorials of Arbitrum and Optimism.
Arbitrum
1. We first need to add the Arbitrum network to the Fox Wallet. There are two ways.
the first method:
Open "http://bridge.arbitrum.io/", then click "Add/Switch to Arbitrum Network", and add the Arbitrum network after the little fox allows and confirms the switch.
The second method:
Select "Custom RPC" on the Little Fox interface.
Fill in the following parameters in turn and save:
Network name: Arbitrum One (can also be customized)
Add RPC URL:
https://arb1.arbitrum.io/rpc
Chain ID: 42161
Ticker: ETH
Block browsing URL:
https://explorer.arbitrum.io
After the addition is successful, we see the "Arb1" network.
2. The next operation is to deposit L1’s Ethereum assets into L2’s Arbitrum, so we first switch the wallet to the ETH mainnet.
On the left side of the interface, we can see the balance of the ETH main network, enter the amount transferred to the second layer network Arbitrum, and then click "deposit".
It prompts that the process of receiving the account may take about 10 minutes, we click "PROCEED" (execute).
At this time, Little Fox will pop up the asset bridge cross-chain gas fee and the total transaction amount. After checking, we click "Confirm".
After the transfer is successful, we will see the transaction ID and L2 balance below:
Everyone should know that our interaction with winning airdrops is not just about transferring assets from L1 to L2. In addition to cross-chain, we must use dapp on the L2 network to complete the interaction.
If the most perfect operation plan is considered, the assets must be transferred back to L1 after interacting with the dapp on the L2 network.
3. Next, let's go to the Layer2 Arbitrum network interaction dapp and open the Arbitrum One portal:
"http://portal.arbitrum.one/", and find an Arbitrum ecological application to interact with.
The "COMING SOON" application has not been migrated to Arbitrum yet. We choose the one with the "LIVE" logo. The editor uses UNISWAP as an example:
Next, we click on the LOGO to enter UNISWAP and log in to the Arbitrum ONE (Arb1) Layer 2 network.
At this time, the interface will display Arbitrum's LOGO and the cross-chain assets after confirmation:
We choose to exchange assets, click exchange and confirm on Little Fox, we will find that the service fee of the second-tier network is quite cheap.
4. The last step is to transfer the assets of L2 back to L1, but it should be noted that there is a 7-day waiting period for the funds to be transferred back.
We go back to "https://bridge.arbitrum.io/", the little fox logs in to the Arb1 layer 2 network, and enters the number of spans returned.
Click the interface "withdraw" and "PROCEED" to execute, and confirm in the Fox Wallet.
So far, we have perfectly completed the interaction of the first Layer 2 solution Arbitrum.
Optimism
Continue to interact with the second item: Optimism.
1. First, let’s add the Ethereum Optimistic network to the Fox Wallet and open the website:
“https://chainid.link/?network=optimism”
2. Then we transfer the assets of the Ethereum mainnet to the Optimism layer 2 network and open the website:
"https://gateway.optimism.io/", then we click "Deposit", and the little fox wallet switches to ETH Mainnet.
After we enter the amount transferred to the second-tier network Optimism, click "DEPOSIT", and then the interface will display an interface for approving the transfer contract, which contains the amount and amount you want to transfer.
After confirming that it is correct, click "DEPOSIT", and allow and confirm the payment on the pop-up interface of Little Fox.
The entire cross-chain process may take 5-20 minutes, and you can check the progress on ETHERSCAN.
3. When we see the "DEPOSIT COMPLETE" prompt, it means that the asset transfer is successful, and we can go to UNISWAP to interact.
Open "https://app.uniswap.org/#/swap" and switch to the "Optimistic Ethereum" layer-2 network.
Then we select the asset to be exchanged on the interface and enter the exchange amount, then click "Exchange" → "Confirm Exchange".
At this time, the little fox pops up the exchange gas fee interface, and we can see that the gas fee of the Optimism layer 2 network is very low.
After we complete the exchange, we will do the last step of asset transfer from L2→L1.
Open "https://gateway.optimism.io/", and the little fox selects "Optimistic Ethereum".
We select the assets and quantity transferred from L2 back to L1 in the middle interface, and click "WITHDRAW" (take out).
The transaction will be executed automatically after the gas fee is paid in the Little Fox Wallet. Similarly, the transfer from L2 to L1 will take about 7 days.
