Launched in August 2020, Serum is a first-of-its-kind order book-based decentralized exchange that allows buyers and sellers to instantly trade cryptocurrencies on Solana at their specified price and negligible fees.
The Serum protocol is built on Solana - the fastest, and one of the cheapest blockchains that also has cross-chain support. Moreover, Serum is fully usable from Ethereum and seamlessly integrates with Ethereum dApps, allowing users to transact freely between blockchains.
SRM is Serum's native cryptocurrency, is used to pay fees on Serum and participate in its governance.
