reading the ledger…
no peeking.no deleting
Seal a call about any coin. It is timelocked to the minute you pick: nobody can read it before then, not even you, and nobody can hide it after. Then it opens by itself and the chart grades it.

how it works
Sealed, then opened. Nothing in between.
01 · seal
Your browser locks it
The call is encrypted in your browser to a future round of drand, the randomness beacon run by the League of Entropy. The ciphertext goes on Solana in a memo, signed by your wallet, with a block time nobody can change.
02 · wait
The key doesn't exist yet
A round's key is a threshold BLS signature the drand network only produces when the round comes. Until then there is nothing to leak, bribe or subpoena. Not our server, not you.
03 · open
It opens by itself
At the minute, drand publishes the round and anyone can decrypt the call, us included. Price calls are graded on Coinbase and GeckoTerminal candles from your seal to the open.
- You can't hide a miss. With a hash commitment you choose what to reveal. Here the reveal happens without you.
- You can't copy a caller. Every call names its wallet inside the ciphertext. Resubmit someone else's and it opens void.
- Bold is scored, safe is not. Right, you win the move you called: 100·ln(target ÷ price at the seal). Wrong, you lose it. A target already behind the price scores 0.
- Our server is optional. The call lives on Solana and opens with drand. Any tlock tool can open it, or the button on every call page.
