The leader tokens of the ETH ecosystem chain are usually considered to be the native token of Ethereum, ETH. In addition, tokens such as UNI and LINK can also be regarded as leaders in specific fields, as detailed below:

- ETH: Ethereum is an open-source public blockchain platform with smart contract functionality. ETH is its native Token, used to pay transaction fees on the network, provide staking rewards under the PoS consensus mechanism, and is the foundation for creating ERC-20 Tokens and other digital assets. It occupies a central position in the ETH ecosystem and is key to the operation of the entire ecosystem.
- UNI: Uniswap is a decentralized trading protocol based on Ethereum and is one of the earliest and largest DEX protocols in the crypto market. UNI is its governance token. Uniswap holds an important position in the decentralized trading space, with a large user base and high trading volume, making it a significant token in the decentralized finance (DeFi) sector of the ETH ecosystem.
- LINK: Chainlink is an oracle network based on the Ethereum blockchain, and LINK is its Token, used to pay Chainlink node operators to retrieve data from off-chain sources, among other functions. Oracles are an important bridge connecting blockchain with real-world data, and LINK plays a key role in solving blockchain data retrieval issues, being the leader Token in the oracle field of the ETH ecosystem.
