Introduction

The Optimism Network or Optimism is a second layer solution, which was created to solve the scalability problems of the Ethereum network. Optimism in the word means optimism, and the Optimism network was created based on this approach. The Optimism network uses Optimisitic Rollup to increase scalability. In this solution, the Optimism network collects and executes transactions in its network and sends them in a compressed form to the Ethereum network, causing the scalability, speed of transactions and their fees to be significantly reduced.

In the optimistic approach that the Optimism network uses, all transactions that are validated by network validators are considered valid and processed. This process ensures that transactions are not validated separately and their processing time is greatly reduced. Also, each member of the network or validators has up to one week to check the set of transactions and if a fake transaction is found, inform the network and receive a reward.

The Optimism network was created with the aim of solving Ethereum's scalability problems and making this network efficient. Optimism has built its design on four main pillars: simplicity, pragmatism, sustainability and optimism. These features allow the Optimism network to operate simply and effectively and provide various facilities to users and developers.

Sushiswap

Sushi Swap Decentralized Exchange is introduced as a fork of UniSwap Decentralized Exchange. In fact, this exchange is a modified version of UniSwap, which operates on the Ethereum blockchain. This decentralized exchange was created in 2020 by a person or two groups with the nicknames of Chef Nomi "Chef Nomi" and "0xMaki". Detailed information about the identity and characteristics of the creator or creators of Sushiswap is not available. Unlike older exchanges such as Binance, which make their own market, SushiSwap, based on its community-oriented nature, uses users as liquidity providers and rewards them with SUSHI tokens for doing so. Holders of this token are allowed to comment on legislation and set protocols. Also, a percentage of the transaction fee is considered for these people.

Uniswap

The Uniswap platform is a decentralized exchange (DEX) based on the Ethereum network, where people can exchange ERC20 tokens. In this exchange, there is no need for buyers and sellers to create demand and this is done through an equation, which automatically adjusts and adjusts the value. In this exchange, there is no need for authentication and everyone from anywhere in the world can trade in it. But what is UniSwap? In this article, we will introduce this popular DEX, its idea and goals, how it works, Uniswap services and services, introduction of UNI token, road map, collaborations, introduction of the production team and methods of buying and maintaining Uni token. Uniswap is an Ethereum-based decentralized exchange for trading ERC-20 tokens. Unlike many exchanges that are centralized and you have to trust intermediaries, this DEX is a tool for people in the community and people can use it to exchange tokens, so that there is no need for intermediaries and third parties; At UniSwap, you trust smart contracts. Also, unlike many other exchanges, UniSwap does not match the buyer and seller to determine the price and execute the trade. Here, a simple matching equation and liquidity pools are used.

Velodrome

The Velodrome platform is a decentralized exchange (DEX) based on the Optimism blockchain. Since the Velodrome decentralized exchange is based on the Optimis blockchain, it offers all the features of this blockchain to its users. In fact, this exchange allows digital currency market participants, users and traders to exchange their cryptocurrencies with each other using this exchange.

This decentralized exchange also functions as an automated market maker or an AMM based on the Solidity programming language. Decentralized exchange Velodrome is a spin-off from Solidity, an innovative DEX designed by Andre Cronje, the founder of Saline Finance, whose economic model is designed with VELO and veNFT tokens. In addition to this, the Velodrome platform will allocate 65% of all VELO tokens to the community, including airdrops to WeVE holders (30%), Optimism users (25%), DeFi users (25%) and liquidity providers ( 20%).

Methodology

• Three DEXs were used for this analysis: 1-Sushiswap 2-Uniswap 3-Velodrome

• The following tables were used to extract data:

  optimism.sushi.ez_swaps
  optimism.core.fact_event_logs
  optimism.velodrome.ez_swaps
  

• The swap data for Sushiswap and Velodrome were in specific tables, but for Uniswap, the following code was used:

  from optimism.core.fact_event_logs
    where origin_to_address in ('0xe592427a0aece92de3edee1f18e0157c05861564','0x68b3465833fb72a70ecdf485e0e4c7bd8665fc45')
      and event_name = 'Transfer'
      and tx_status = 'SUCCESS'
  

• The date filter of this analysis has been in the last 30 days until now

• The following code was used to extract pools in Uniswap:

  case contract_address
        when '0x85149247691df622eaf1a8bd0cafd40bc45154a9' then 'WETH-USDC'
        when '0x95d9d28606ee55de7667f0f176ebfc3215cfd9c0' then 'DAI-WETH'

        when '0xf1f199342687a7d78bcc16fce79fa2665ef870e1' then 'USDC-USDT'
  end as pool_name
  

• The following code was used to extract assets in Uniswap:
