In the Web3 era, decentralized finance (DeFi) has rapidly evolved, creating a pressing demand for interoperability, deep liquidity, low fees, and seamless user experiences. The 0x Protocol has emerged as a core infrastructure platform enabling this vision. But what makes this project unique? Let’s dive in.
How Does 0x Protocol Work?
0x operates on an "off-chain order relay, on-chain settlement" model:
Key Components:
- Makers: Create trade orders and provide liquidity.
- Takers: Match orders via APIs or DEX interfaces.
- Relayers: Transmit and manage off-chain order books.
- 0x Smart Contracts: Validate and execute trades on-chain.
Process Flow:
- Order Creation: Makers sign off-chain orders → share with Relayers or Takers.
- Order Execution: Takers submit signed orders to the blockchain → 0x contracts verify and swap assets.
This approach reduces gas costs, accelerates order matching, and simplifies DEX development.
