Raydium is the first AMM built on Solana to leverage a fully decentralised central limit order book for the Serum Decentralized Exchange.As an AMM inside Serum, Raydium has a first-mover advantage, and it will play a key role in bringing new and current projects and protocols into the ecosystem. Raydium and the RAY token will provide a foundation for facilitating further development with the ecosystem as a whole, as the protocol serves as a bridge for projects wishing to extend to Solana and Serum.On February 21st, 2021, Raydium launched its main net, with 555,000,000 tokens issued at genesis. Over the course of three years, 34% of all tokens will be issued as liquidity mining incentives. Raydium has set aside 30% of its tokens for collaborations and the growth of the Raydium ecosystem.
