Exploring the Optimism Ecosystem! Top Dapps Introduction

Welcome to the Optimism ecosystem! Optimism, a Layer 2 scaling solution for Ethereum using Optimistic Rollups, offers faster transactions, lower gas fees, and EVM-compatibility. We’ll explore the top dApps thriving on Optimism in this article!

What is Optimism?

Optimism is a Layer 2 scaling solution for Ethereum, designed to enhance the network’s capacity by reducing fees and increasing transaction throughput. It operates on the principle of Optimistic Rollups, which allow for the execution of smart contracts and transactions off the main Ethereum chain (Layer 1), while still inheriting the robust security properties of Ethereum.

Optimism achieves this by assuming transactions are valid by default (hence “optimistic”) and only running computation through a fraud-proof mechanism in the event of a disputed transaction. This approach significantly reduces the amount of data that needs to be processed and stored on the Ethereum mainnet, leading to lower transaction fees and faster processing times compared to executing the same operations on Layer 1. However, this method also leads to a seven-day waiting period for withdrawals back to Ethereum.

As an EVM-compatible Layer 2, developers can deploy Ethereum smart contracts on Optimism with minimal changes, making it a highly accessible platform for scaling dApps. Additionally, as one of the earliest launched Layer 2 solutions, Optimism’s friendly development environment and its long-term development have cultivated a diverse and rich ecosystem. With a Total Value Locked (TVL) of $7.88 billion, Optimism ranks second among all Layer 2 solutions, only behind Arbitrum.

If you’re interested in dApps on Optimism but unsure where to start, let’s take a look at some amazing projects on Optimism!

Top DApps Within the Optimism Ecosystem

The Optimism is renowned for its extensive collection of DeFi projects but also hosts an array of other initiatives including bridges, social, tools, and NFT platforms. Here’s a snapshot of the standout projects that are shaping the future of the Optimism ecosystem:


Synthetix is a decentralized liquidity layer on Ethereum and Optimism that serves as a liquidity backend for some of the most exciting protocols in DeFi. 

By engaging in SNX staking, users not only earn interest but also gain the ability to borrow sUSD. This synthetic USD can be utilized across an extensive variety of Real-World Asset (RWA) Dapps within the Synthetix ecosystem, allowing users to trade in crypto, Forex, commodities, and more, all represented as crypto assets.

Synthetix currently supports eight Dapps, making it the highest TVL Dapp on Optimism, with approximately $274.33 million.

Velodrome, modeled after Solidly, is an Automated Market Maker (AMM) Decentralized Exchange (DEX) designed to enhance liquidity depth and minimize slippage for key token pairs within the Optimism ecosystem. 

Standing out in the crowded DEX landscape, Velodrome lures participants with its incentivized liquidity pools, creating an environment ripe for engagement and investment. Moreover, it empowers its users with governance capabilities through their token (VELO), allowing them to have a say in the protocol’s token distribution and decision-making processes. This strategic approach not only improves trade efficiency but also fosters a democratic ecosystem where users’ inputs shape the future direction of Velodrome.

Currently, Velodrome is the largest DEX on the Optimism network, boasting a TVL of approximately $130.08 million.

Worldcoin is a crypto project co-founded by Sam Altman, the CEO of OpenAI. This project aimed at creating a global digital currency that leverages unique biometric identification technology to ensure one person holds only one account. 

Just by scanning the eyeball with an Orb (iris scanner), users can obtain an exclusive human digital passport in the Worldcoin app. This app serves not only as identity verification but also allows users to manage and transfer digital assets, as well as receive Worldcoin tokens.

In a bid to expand its ecosystem and enhance scalability and transaction efficiency, Worldcoin announced its migration to the Optimism network in August 2023. This move is expected to benefit Worldcoin users with faster transactions and lower fees, further aligning with its mission to foster a more inclusive global financial system.

AAVE V3 is the latest iteration of the AAVE protocol, a DeFi platform renowned for pioneering liquidity pool lending services. This version introduces several enhancements aimed at improving user experience, security, and efficiency. 

Key features include gas optimization for lower transaction costs, increased scalability through cross-chain functionality, and new risk mitigation tools such as the Portal, which facilitates seamless asset transfers across supported blockchains. AAVE V3 also incorporates more sophisticated governance mechanisms and introduces “High-Efficiency Mode” for leveraged positions and “Isolation Mode” to limit exposure to new assets. 

These upgrades solidify AAVE’s position as a leading platform in the DeFi space, offering users more flexibility, security, and opportunities for earning interest on their cryptocurrency holdings.
