DYDX is the native token of the dYdX Chain, a separate blockchain network developed specifically for the dYdX platform. It is used within the dYdX Chain ecosystem for various purposes such as governance, staking, and participating in liquidity pools. The token is integral to the functioning of the dYdX Chain, facilitating transactions and incentivizing network participation. ETHDYDX typically refers to a wrapped or bridged version of the DYDX token that exists on the Ethereum blockchain. ETHDYDX aims to enable the token's use within the Ethereum ecosystem. This includes trading on Ethereum-based decentralized exchanges, participation in Ethereum-based DeFi protocols, and compatibility with Ethereum wallets and smart contracts.While ETHDYDX maintains the value equivalence with the native DYDX token, its use cases are adapted to the Ethereum network. It allows users to leverage the broader Ethereum ecosystem while holding a token originally from the dYdX Chain.
