New Delhi: Flipkart on Friday partnered Ethereum-based Blockchain platform Polygon to set up a centre of excellence (CoE) that will work on research and development of Web3 and metaverse commerce use-cases in India. Still in its early days, decentralised technologies are yet to become more mainstream. However, the partnership will be an opportunity to create a large impact and deliver on the promise of Web3 for all, the companies said in a statement.
