What is Sera?

Sera is a fully on-chain Central Limit Order Book (CLOB) decentralized exchange built on Ethereum. Unlike AMM-based DEXs, Sera enables traders to place limit orders at specific prices, providing:
  • Zero Slippage: Execute at your specified price or better
  • Capital Efficiency: No liquidity locked in pools
  • Professional Trading: Order types familiar to traditional finance

​
Key Features

Limit Orders

Place buy and sell orders at specific prices. Orders sit on the order book until filled or cancelled.

Market Orders

Execute immediately against existing orders on the book at the best available prices.

Order NFTs

Each order is represented as an NFT, enabling order transfers and advanced composability.

Sera is currently deployed on:
