For now, the feature will only be available to a group of users selected by Instagram and will include:
• Support for Ethereum and Polygon (but later they promise to bring Flow with Solana);
• Wallets Rainbow, MetaMask and Trust Wallet, and soon Coinbase, Dapper and Phantom;
• The ability to share NFT in the main Instagram feed, Stories or in messages.
In the future, the company plans to add the same to Facebook and roll out more NFT-related features, but first they want to get some early feedback.
