Teardown: Why is OP the first choice for DeFi protocols?

Everyone is talking about Optimism these days. Coinbase just announced that they will be launching a new L2 blockchain called "Base", built on the $OP Stack. So this article will introduce you to:
What is Optimism;
Why $OP is the top choice for DeFi;
Some DeFi protocols with huge potential;
What is Optimism?Optimism is one of the star layer 2 solutions on Ethereum. With many DeFi advancements on L2, Optimism is definitely at the forefront.
Similar to Arbitrum, Optimism uses Optimistic Rollups to increase transaction throughput and reduce gas fees. Developers are able to create scalable and efficient applications on top of Ethereum and benefit from the network’s existing infrastructure.
Yesterday Coin Base announced that they are launching a new L2 blockchain called "Base", built on the $OP stack, providing a secure, low-cost, development-friendly solution for anyone to build decentralized applications anywhere Staff friendly manner.
The collaboration is dedicated to upgrading the Optimism mainnet, Base, and other L2s to the initial superchain. And it is hoped that the super chain can develop into a vast network, maximize interoperability, share decentralized protocols, and standardize its core primitives.
What makes Optimism a top choice for DeFi?$OP focuses on compatibility with Ethereum. Any Ethereum dApp can easily integrate with Optimism and benefit from its scalability and reduced gas fees. This resulted in many popular dApps and DeFi protocols migrating to $OP.
Optimism has been on mainnet for some time and is battle-tested by several well-known projects, including Uniswap, Synthetix, and MakerDAO.
With major network upgrades coming soon, activity in the Optimism ecosystem is expected to reach new heights soon.
DeFi TVL on Optimism rose 41% last month, second only to Arbitrum. So let’s take a look at some interesting DeFi protocols:
VelodromeVelodrome is the largest and fastest growing DEX on Optimism.
In a way, it is a hybrid of Curve, Convex, UNIV2, combining multiple protocol layers in one center.
The exchange features an innovative liquidity pool called Velocity Pool, where liquidity providers can earn trading fees and revenue on their collateralized assets.
Velodrome also rewards users for participating in the ecosystem with the native token $VELO.
Velodrome allows many popular protocols, such as Lido and Frax, to incentivize their liquidity for their token holders
Velodrome's TVL has grown exponentially since early 2023 and now exceeds $277 million.
SynthetixSynthetix is ​​a decentralized asset insurance protocol that allows its users to mint and trade a variety of derivatives via synthetic assets called "Synths."
Synthetix is ​​at the forefront of the DeFi movement, with the potential to create a massive market for the tokenization of real-world assets on Ethereum.
Sonne FinanceSonne Finance is the first to offer a fully transparent and decentralized peer-to-peer lending solution.
SonneFinance’s TVL has been rising steadily since the start of 2023. It has also become one of the biggest bribers on Velodrome.
DeFi protocols worth paying attention toBullsToros Finance is a DeFi platform that gives users the opportunity to earn through Dynamic Vaults.
Perpetual ProtocolPerpetual Protocol is an on-chain perpetual futures DEX with deep liquidity and composability. With $17 million in TVL, Perpetual is prominent in the Optimism ecosystem.
PikaProtocolPika Protocol is a perpetual swap that allows users to trade forex and cryptocurrencies with up to 100x leverage and almost 0 slippage. Pika Protocol uses an automated market maker model that requires minimum liquidity to guide transactions.
