Mailchain has added support for Polkadot’s substrate protocol so that users can for send and receive rich-media HTML messages between substrate blockchain addresses through a simple, email-like interface.
The implementation supports Edgeware, which has the ‘Contracts’ Substrate Runtime Module Library enabled. This enables message metadata to be included in extrinsics and sent between substrate account addresses following the Mailchain specification.
There are many use cases for sending messages between blockchain accounts, including:
Users can make payments directly to addresses in response to an invoice.
Receipts or statements can be sent directly to payment addresses, making accounting, payment tracking, and proof-of-purchase easier. …
