OpenSea has launched its upgraded OS2 marketplace, introducing new features such as multi-asset support and a rewards program. The OS2 platform now facilitates trading of NFTs and ERC20 tokens across 19 blockchains, including Flow and ApeChain, enhancing its competitive edge against platforms like Blur and Magic Eden. A key addition is the 'Voyages' rewards program, which employs an XP system to boost user engagement. OpenSea's market share has climbed to over 40%, with 70% of active NFT wallets utilizing the platform. The anticipated release of the SEA token is expected to further drive user participation and solidify OpenSea's market position.
