Arbitrum usage guide and Layer 2 progress

As of September 6, the lock-up volume of all second-tier networks exceeded US$1 billion. (L2beat)

Arbitrum has launched Layer2 Summer, is it far?

On September 1, Arbitrum officially announced the launch of the mainnet test version of Arbitrum One. Uniswap, Sushiswap , Balancer, DODO and other applications have been launched simultaneously. Steven Goldfelder, the co-founder of Offchain Labs behind Arbitrum, revealed that Arbitrum will not issue tokens in the short term, and the recent vision does not include the token plan. The $120 million Series B financing is only equity financing. But DAO may decide to tokenize in the future.

Arbitrum Layer 2 network usage steps

  • Add Arbitrum One network. Automatically switch the network by visiting the Arbitrum Asset Bridge ( or manually add it through Metamask.
  • Transfer the Ethereum mainnet assets to the Arbitrum One Layer 2 network through the bridge ( Or use Celer’s cross-chain asset bridge cBridge ( to cross-chain assets from other networks (such as BSC, Polygon) to Arbitrum, and only need to pay a relatively cheap bridge fee.
  • Select the dapp application you want to use and perform related operations.
  • Withdraw funds from the Arbitrum One Layer 2 network to the Ethereum main network.

Arbitrum, Optimism and Ethereum fee comparison

  • Entry cost

Before using L2 applications, users need to recharge their assets on L1 to the L2 network through a “gateway” or “bridge”, and then they can interact with the L2 version of the application. Take the transfer of ETH to L2 as an example, the cost of entering Optimism is twice that of Arbitrum, and it is 10 times that of the transfer cost of the Ethereum mainnet.

  • Transfer cost

For transfers in the same network, the transfer cost on Arbitrum and Optimism is 40% of the Ethereum main network.

  • Dex transaction costs

Uniswap V3 is a DeFi transaction protocol currently deployed on the three networks of Ethereum L1, Optimism and Arbitrum. Taking the ETH-USDT trading pair as an example, the transaction costs on Arbitrum and Optimism are basically the same (the actual test cost is 4.3 and 4.4 US dollars), which is 7% of the Ethereum main network transaction cost.

  • Add liquidity cost

Take the addition of ETH-USDT liquidity in Uniswap V3 as an example. The Ethereum mainnet costs US$120, Arbitrum costs US$16 (13% of Layer 1 cost), and Optimism costs US$4.4 (3.6% of Layer 1 cost).

Recent progress of each Layer 2

Optimistic Rollup route

Advantages: EVM compatibility.

Disadvantages: There is a long challenge period.

  • Optimism recently released a new gateway interface, which allows users to transfer any tokens between the Ethereum main network and the Optimism layer 2 network. The emergence of Hop Protocol allows users to quickly withdraw USDC and USDT from Optimism to the Ethereum mainnet, which avoids the 7-day waiting time for Optimistic rollup withdrawals.
  • Metis is a fork of OVM that uses Optimism. It plans to establish a public testnet in September and release the mainnet in October. It further simplifies the transition of existing Ethereum applications to L2 through Polis middleware.


    100% EVM compatible , the project party does not need to rewrite the program when migrating. 74 projects have been deployed on the testnet, and 5 projects have been launched simultaneously on the mainnet. Previously announced that there are more than 400 projects supporting Arbitrum, leading the Ethereum Layer 2 track.

ZK Rollup route

Advantages: safety.

Disadvantages: not compatible with EVM.

  • zkSync 2.0 claims to have the security, high throughput and efficiency of ZK Rollup (ZKR), as well as EVM compatibility, so it is considered the best Ethereum expansion solution. Alex G, the co-founder of Matter Labs, the team behind zkSync, said that the design and implementation of zkEVM is actually a very difficult project. On their upcoming public testnet, they implemented zkEVM based on a compiler.
  • StarkWare has two main products: ZK-Rollup expansion network StarkNet and L2 expansion engine StarkEx. Among them, StarkEx can be regarded as an application scenario of StarkNet. At the end of July, StarkEx version 3.0 was launched on the mainnet, which focused on allowing L2 users to easily interact with L1. As of August 22, the total number of transactions settled by StarkEX exceeded 10 million, and the number of registered users exceeded 100,000. StarkWare has provided basic services for dydx, deversifi and Immutable X. The second-tier lock-up volume of these three projects ranks 1, 7 and 13 respectively. dydx and Immutable X have shown strong competitiveness in derivatives and NFT games respectively. Nethermind’s Warp team is using “EVM->Cairo Compiler” to convert ERC-20 contracts from EVM byte codes to StarkNet contracts for deployment on StarkNet. The next goal is to transfer arbitrary smart contracts from EVM language Yul to Cairo.
  • Loopring, as the first Ethereum second-layer network to implement the zkRollup solution, has recently ushered in a new wave of growth due to its support for NFT casting, trading and transfer functions.

Some agreements are helping Optimistic Rollup to solve the exit period problem. Matter Labs and Starkware are working hard to achieve the ability to perform EVM-like calculations in ZK Rollup. Rollup’s comprehensive strength is increasing, the amount of locked warehouses is growing rapidly, and more and more projects are migrating to the second-tier network, waiting for the arrival of Layer 2 prosperity.

How to understand Loot and its ecology

The total amount of Loot is 8,000, and the creator has reserved 222 for himself as a reward. Each loot contains 8 types of equipment, so there are 8 lines of words, each line represents a type of equipment, which are weapons, breastplates, helmets, waist armor, foot armor, hand armor, necklace and ring.

Fair casting

Different from the top-down ICO logic of “Issuer Produced by Issuer, User Purchased” in most NFTs, Loot has created a more decentralized NFT casting method. Users can cast Loot on Etherscan through Write Contract. , Except for gas fees, there are no additional holding costs, and anyone has the opportunity to participate in the casting and issuance.

NFT 高 高

Anyone can use Loot to connect and expand with other protocols, similar to DeFi stacks, and can continue to create and build on the basis of Loot. Loot allows different games and meta-universes to share a set of scalable attributes, creating the lowest level and even cross-chain NFT framework. According to information compiled by Loot, 41 projects have been reassembled or built on top of Loot. Everyone can recreate around simple texts. The gameplay that has appeared so far:

  • Use the program to automatically generate pictures based on character strings.
  • Generate the corresponding pixel character based on the character string.
  • Write a story for each equipment.
  • Guilds divided by items and attributes.

Any blockchain game can introduce props or characters in Loot, and can quickly capture a large number of user groups.

Holds interest in Loot

  • airdrop. Adventure Gold airdrops 10,000 AGLD tokens for each Loot bag. Adventure Gold itself is a game project that has not yet been developed. At present, AGLD has basically become the governance token of the entire Loot community.
  • In the future, Loot holders may obtain equipment or characters in the game, which can be used for rent or sale, thereby generating cash flow and turning them into interest-bearing assets.

Loot concept project

  • The founder of the Loot project, Dom Hofmann, launched a new project More Loot (MLOOT) with dynamic supply . The dynamic output of Ethereum is 1/10 of the block rate of Ethereum, about 250,000 per year, and the current upper limit is 1,316,005. The user is free to mint, and only gas fee is required. As of September 7, it had minted 86,696 and held 18,287 addresses.
  • On September 6, the founder of Yearn Finance was inspired by Loot to launch the adventure game Rarity in Fantom , in which players can create summoners and there is no limit to the total amount of Rarity. There are 11 characters in the game, namely, bard, bard, priest, druid, fighter, monk, paladin, ranger, patrolman, wizard, and wizard.
  • On September 3, the Chinese team developed the Chinese version of the Chinese Loot airdrop to Loot holders, providing all Loot holders with the “Chinese translation version” NFT of the original Loot held by them, which attracted the attention of the founders of AAVE .
