Solana Order Book
A Solana order book is a decentralized ledger that records buy and sell orders for assets on the Solana blockchain. Unlike traditional order books on centralized exchanges, Solana's order book operates on-chain, providing transparency, trustlessness, and high performance. It is a key component of Solana’s decentralized finance (DeFi) ecosystem, enabling efficient and scalable trading.
