Write
Draft the words that need time. A prediction, a promise, a letter.
TIME-CAPSULE LETTERS ON SOLANA
Sealed on Solana.
Write it now, reveal it later. Every letter will be sealed in one Solana transaction — unread by anyone, including us, until the block you choose.

What exists today, and nothing more. The contract address and the trade entry both arrive at launch.

03 · The developing line
Every letter crosses it once.
Under the safelight a negative becomes a print. Bench demo — values are generated at runtime, nothing here is chain data.

04 · Hanging prints
Five frames, one ritual.
Write, seal, wait, break, prove. Each print develops as you reach it.
Protocol as designed. The letter protocol ships in Phase 2 — these steps describe it, not a live service.

02
Seal
The letter is hashed and committed in one Solana transaction.
03
Wait
On-chain, unread. Nobody can open it early. Not even us.
04
Break
The block you chose arrives. The seal breaks and the letter stands revealed.
05
Prove
The reveal hash matches. The words were written before the world saw them.

After the break
Becomes public, by design
The letter, in full
When the seal breaks, the words, the hash and the block are there for anyone to read. That is the point.
06 · Readouts
Numbers a seal can keep.
Four readouts. Each one is a property of the mechanism, not a promise.

07 · Process trays
Commit, reveal, and nothing in between.
Tray 01 · commit
Commit
A letter is hashed before it ever touches the chain. What goes up is a fingerprint, not the words.
Tray 02 · reveal
Reveal
At the block you chose, the original is published and checked against the hash. A match is proof it was written first.
Tray 03 · access
Permissionless
No account, no custodian, no gatekeeper. A transaction is the whole ceremony.
Phase 2 · Letter protocol08 · Contact sheet
Three reasons to seal.
Frame 01
Call it before it happens. Let the seal prove you did.
Frame 02
Some commitments deserve a witness that cannot forget.
Frame 03
Write it now, for someone who will need it later.
