Optimism is a Layer-2 scaling solution for Ethereum that aims to significantly reduce gas fees and increase transaction throughput. One of the key features of Optimism is its support for decentralized exchanges (DEXes) that allow users to trade cryptocurrencies without the need for a centralized authority. The Optimism blockchain also supports stablecoins, which are cryptocurrencies that are pegged to a stable asset like the US dollar, and are designed to maintain a stable value.

Stablecoins have gained widespread popularity in recent years due to their ability to provide a stable store of value and reduce the volatility typically associated with cryptocurrencies. Stablecoins are also useful for traders who want to move funds quickly and cheaply between different cryptocurrencies, without being subject to price fluctuations.

On Optimism, stablecoins can be used on different DEXes, such as Uniswap, SushiSwap, and Curve. These DEXes use automated market makers (AMMs) to facilitate trades, which means that users can trade without needing a counterparty. This reduces the need for order books and provides greater liquidity to the market.

The relationship between stablecoins and DEXes on Optimism is important because stablecoins are often used as a trading pair with other cryptocurrencies. This allows traders to move funds between different cryptocurrencies without the need to convert back to fiat currency. Stablecoins are also used as a store of value and a hedge against market volatility, making them a crucial part of the cryptocurrency ecosystem.

The purpose of this dashboard is to explore the dominance of stablecoins inside the Optimism blockchain based on each DEX. By analyzing the usage of stablecoins on different DEXes, we can gain insights into the demand for stablecoins and the overall health of the Optimism ecosystem. This information can be used by traders, investors, and developers to make informed decisions about the use of stablecoins on Optimism.
