How it works
- You write itYour letter gets encrypted right in your browser, to a future round of drand, a randomness network run by universities and companies around the world. The key for that round doesn't exist yet, so nobody can open it early.
- It waits on PolygonThe locked letter sits in the contract and you get the envelope as an NFT. It draws itself on chain, no server behind it.
- The day comesdrand publishes the key, anyone can open it, and once the text goes back on chain the envelope turns into the letter for good.
