"Blinks" is a feature that converts "Actions" on Solana into shareable links, allowing users to easily execute cryptocurrency transactions through various digital paths such as websites, social media platforms, and QR codes. With the newly introduced Blinks and Actions, Solana chain users can now transfer funds on Telegram, buy and sell NFTs on X, and stake in Discord without needing a DApp. Blink has become a powerful tool for Solana, bridging web2 and web3.
