Write a message on your cake, wrap it up, and send. The art and message won't be revealed until the date you specify. Messages can be updated infinitely! Only the latest message is visible, and only the inscription owner can add a new message. See example below:

By making use of the new recursive sat endpoints, only the latest inscribed message will be visible on the main inscription (although there will still be a record of every message when viewed in a block explorer.) HashCakes also make use of an on-chain text minter, allowing you to inscribe your text and set the reveal date directly from the inscription using Xverse wallet!

HashCakes are unique pieces of art, which makes them infinitely more special than any low effort eCard sent by email. Sure, nothing beats physical greeting cards, but can physical greeting cards be endlessly re-used or resold? Furthermore, traditional greeting cards need to be sent via snail mail. HashCards can be sent instantly and efficiently on the Bitcoin blockchain, making them better for the environment and the perfect last minute solution. They have all the same benefits and conveniences as eCards, but without the disappointment!

HashCakes aren't your typical NFT collection. They represent the start of something new, something we call the gift economy. In a gift economy, the more you give, the richer you are. Every time a HashCake is gifted, a new person is introduced to the gift economy, a person who may decide to return the favour as well as send HashCakes to their own network.


With utility like this, HashCakes may just disrupt the entire greeting card industry. Thats right, eCards are officially cool again 😎.
