According to a tweet posted yesterday by Jane Manchun Yong, a technology and app blogger, NFT marketplace Rarible is aiming to add support for Solana (SOL). The tweet demonstrates that Rarible has already set up the backend for working on the Solana integration.
Less than a week ago, Rarible added support for Polygon (MATIC), adding to other networks it supports, which include Ethereum, Flow, and Tezos.
