MemoDueUses
DevnetMemoDue is a one-time sealed note on Solana: you encrypt in the browser, put ciphertext on chain, and share a link whose #k= fragment holds the AES key. You select the unlock time that waits on drand/tlock. Creator can reclaim rent or, after a grace period, a keeper can close for a tip — non-custodial, with a create fee to the treasury.
Sealed bids
Each bidder seals a bid until a shared reveal time. Auctioneers set the unlock; bidders keep their own links until then. No one can peek early — including the auctioneer — without the bidder’s key fragment.
Delayed press releases
Write the release once, lock it to the embargo time, and hand the link to journalists or partners. At unlock, everyone with the link can read the same text together.
Delayed content reveals
Trailers, chapter endings, album lyrics, or drop coordinates that must stay dark until a clock hits. The ciphertext is public; the meaning is not until unlock.
Password and credential handoff
Seal a temporary password, API token, or recovery phrase for a handoff at a set time. Share the link privately; after unlock the recipient reads it in-browser. Keep the fragment secret until you intend to share.
Coordinated product launches
Lock messaging, pricing, or feature copy so regional teams, press, and affiliates unlock the same words at launch. One create, many readers after the round.
Embargoed journalism
Sources and editors can seal a story package to an embargo clock. Recipients get the link early; reading waits on drand, not on trusting every inbox.
Classroom answers after the sitting
Publish the answer key as a sealed note timed to the end of the exam window. Students get the link when you choose; nobody decrypts early without the key.
Deal term sheets at announcement
Seal draft terms or a summary for counterparties and counsel, unlock timed to a public announcement. Useful for coordination — not a substitute for counsel or filings.
Delayed whistleblower package
Seal a report to unlock after a deadline you choose, then share the link with a trusted reader or outlet. Timed delay is clock-based; it does not prove events or protect identity by itself.
Gifts and surprise messages
Birthday notes, scavenger clues, or a message that should open on a date. Warm and simple: create, share the link, wait for unlock.
Open after a milestone date
Escrow-adjacent: seal terms or a release note to a calendar date you agree on. Honest limit — unlock is clock/drand, not an on-chain oracle for off-chain events (delivery, payment, or signatures).
Appoint a future reader
Create now, keep the key fragment yourself, and hand the full link later — or leave instructions for when someone should receive it. Content stays sealed until unlock and until they have #k=.
Puzzle and ARG clues
Drop sealed clues that open on schedule across a campaign. Players share links; the chain holds only ciphertext until the round publishes.
Timed personal reveal
A letter or instruction set to unlock on a future date — dead-man / inheritance-style timing. Not legal advice and not a will: clock unlock only; plan for who holds the link and what happens if it is lost.
Not legal advice. Unlock is clock- and drand-based, not an event oracle. Anyone with the full link (including #k=) can read after unlock — keep that fragment secret until you mean to share. Devnet only. See the FAQ.
