Mailchain is email for web3. Today, there is no direct way to communicate via blockchain addresses. Currently users are forced to make trade offs when they link email addresses and lose pseudo-anonymity, or join chat groups for broadcast messages where it's hard to keep track of relevant communication. Without communication as a first class citizen, many actions taken for granted on the Internet cannot take place in web3. Users can’t receive direct communications related to their savings, loans, and financial positions. They can’t receive information from projects they care about in the context of how they interact with them. They can’t contact others in their community, for example, to make an offer to purchase a digital collectible. Businesses can’t receive receipts for payments, or invoices. Developers can’t be reached in the event of security issues and can’t send out important communications to their users if there is an issue, upgrade, or decision to be made. Mailchain provides a cross protocol platform for sending and receiving messages between blockchain addresses. Users don’t need to reveal private keys or any other information about themselves. It’s as simple as using webmail.
