Overview 👀 ~ 6 min read

In this dashboard, I will answer this question from Flipside Crypto:

• Where do people go when they bridge to Optimism from Ethereum?
• What are the 10 most popular first destinations for users that have just bridged from Ethereum?
• What has this been for each day in the past month? How has this changed over the last three months?
• Last six months?

Introduction 💭

What is Optimism Ethereum?

Like other L2 solutions, the Optimism team saw an opportunity to be a new scaling solution for Ethereum without compromising security and decentralization as shown in the trilemma. Optimistic Ethereum is an EVM compatible rollup chain designed to be fast, simple, and secure, and allows users to interact with any Ethereum application at a fraction of the cost by using optimistic rollups.

You can think of optimistic rollups as a smart contract that bundles (or “rolls up”) transaction data and moves it off chain for faster processing. Optimistic rollups are distinct from zero knowledge (ZK) rollups, because they use a different method of verification: while ZK rollups rely on each batch of transactions to have their own ‘validity proof,’ optimistic rollups assume all transactions are valid. .[1]

What is Hop protocol?

Hop protocol operates effectively by leveraging Bonders, who, by providing liquidity, earn a fee. Technically, a user will send any amount of token to Bonders on the source chain, which is where the asset is being sent from. After that process, the Bonder will send the asset to the user’s counterpart on the destination chain.

Hop protocol plays a significant part in the transaction by ensuring that the Bonders have sent the tokens. No user will be happy if they send their token to Bonders, but they cannot reach the destination blockchain. Furthermore, the system employs a particular type of token called hTokens. These tokens also act as a technique to ensure that all transactions are accurately recorded. [2]

What is Across?

Across is a protocol for optimistic cross-chain bridges that allows users to complete transactions on different chains at a timescale that is very near to instantaneous. This is made possible by the fact that Across is a cross-chain bridge. This objective is attainable with the implementation of an optimistic oracle, bonded relayers, and single-sided liquidity pools, as these are the mechanisms by which this goal can be accomplished.

Methodology 🧠

To solve this questionI first needed some contracts For the transfers that were made through the Optimism native bridge, I considered the contract 0x99c9fc46f92e8a1c0dec1b1747d010903e884be1 and categorized the transactions into two categories: ethereum and non-ethereum. I found the addresses of all the users who bridged from Ethereum tables (ethereum.core.ez_eth_transfers and ethereum.core.ez_token_transfers). Then I considered their first transaction in the Optimism network, provided that the date of their transaction in the Optimism network is greater than the date of their transfer transaction in the Ethereum network. Then I used all the possible tables and based on the transaction ideas I had, I chose 3 of the most transaction destinations in each part. I did the same for Hob protocol and showed Ethereum and non-Ethereum transactions separately I used contract 0xb8901acb165ed027e32754e0ffe830802919727f for Ethereum transactions in Hob protocol. For non-Ethereum transactions in Hob protocol, I used the following contracts '0x3666f603cc164936c1b87e207f36beba4ac5f18a', -- usdc '0x3e4a3a4796d16c0cd582c382691998f7c06420b6', -- usdt '0x3d4cc8a61c7528fd86c55cfe061a78dcba48edd1', -- dai '0x22b1cbb8d98a01a3b71d034bb899775a76eb1cc2' -- matic

and at last for Across i used : Across Protocol: Ethereum Spoke Pool V2 Contract

'0x4d9079bb4165aeb4084c526a32695dcfd2f77381' -- Across Protocol: Ethereum Spoke Pool V2

Some Notes 📝

1. All the written explanations are based on the last 1 month and last 3 months and the last 6 months.
2. If the time period is changed, the descriptions may no longer fit the charts
3. In this dashboard, only the number of users and their transactions have been checked, and the volume of transactions or …etc have not been checked

🧐 For a better understanding of the charts, the groups are numbered as follows

• Group number 1 shows the vote on the velodrome platform
• Group number 2 shows doing a swap on the velodrome platform
• Group number 3 shows the Stake on the velodrome platform
• Group number 4 shows the add a liquidity on the velodrome platform
• Group number 5 shows doing a swap on the Sushi platform
• Group number 6 shows the events, which are divided into 3 categories: transfer, swap and approval
• Group number 7 shows the delegate
• Group number 8 shows purchases from an NFT collection

🕵️‍♀️ observations

past month:

• In the past month, after transferring ETH to the Optimism network, users have had many transactions in the form of approval events with the hob platform, and these transactions have been increasing since the beginning of October.

• Among other events that had a relatively high number of transactions, the transfer event in uniswap v3 and the swap in uniswap v3 can be examples.

• The number of daily users can also be seen in the charts in the same criteria and destinations with a smaller number.

• The total number of bridge transactions in the last month was 10.52k transactions

• The total number of Unique users that have bridge transactions in the last month was 9.16 k Unique users

past 3 months:

• In the last three months, after users transferred ETH to the Optimism network, their transactions were below 1000 transactions per day, and it is clear that in October, the transactions and daily users who were connected with hob increased.

• Among other events that had a relatively high number of transactions, the transfer event in uniswap v3 and the swap in uniswap v3 can be examples.

• The number of daily users can be seen in the graphs in the same criteria and destinations with a smaller number.

• The growth of users and transactions in the last 3 months happened in October

past 6 months:

• In the last six months, after transferring ETH to the Optimism network in September and August, users have registered swap transactions in the velodrome in the pools (vAMM-VELO/USDC) and (vAMM-Op/USDC). Swap was in these two pools in September and August.
• In general, it has been a popular destination for users of the velodrome platform for the past 6 months.
• The number of daily users has progressed with a relatively upward trend, with the difference that many users have started delegating and swapping in uniswap v3.
• The total number of bridge transactions in the last six months was 34.3k transactions.
• The total number of Unique users that have bridge transactions in the last six month was 28.7 k Unique users

Conclusion 🎉 this section

1. In the past month, there have been more destinations for users of Hop protocol and uniswap v3, swap operations have been common in uniswap v3, and since the beginning of October, these activities have been increasing.

2. In the last three months, after users transferred ETH to the Optimism network, their transactions were below 1000 transactions per day, and it is clear that in October, the transactions and daily users who were connected with hob increased.

3. In the last 6 months, after transferring ETH to the Optimism network in September and August, users have registered swap transactions in the velodrome in the (vAMM-VELO/USDC) and (vAMM-Op/USDC) pools.

• In terms of the number of daily users, less than 1000 users have been registered in the data, but on October 13, more than 1000 users have performed operations on the network after transferring their tokens.

past 6 months:

• In the last 6 months, after transferring ETH to the Optimism network, users have the same results as in the last 3 months, and the velodrome (vAMM-OP/USDC, etc.) and doing swaps in uniswap v3 is clearly visible, but a little later in June, a jump has been seen.

Summary 📋

1. In general, the number of users who transfer Ethereum is much higher than the number of users who transfer other tokens.
2. Destinations of users on swap platforms, in some cases uniswap v3 is more common, in some cases Velodrome is more common, the rest of the platforms are the first choice of few users.
3. Users who engage in activities such as delegate, vote, and stake after transferring assets are much less than activities and destinations such as swap.
4. Among the destinations of users who buy NFT, two NFT collections: optimism and NFT: project galaxy are more popular and common.
