Publish a public tender. Any wallet except the buyer can submit a bid, and every price stays a sealed hash until the submission deadline — enforced by the Hedgora smart contract, not by a promise.

// THE LIFECYCLE
Open to all
Sealed to
everyone
Every phase change is decided by block time inside the Hedgora contract. The website only shows the clock — it can't open a bid early, and neither can the buyer. Eligibility is described by the buyer and checked at evaluation, not on-chain.

ONLY A REVEALED BID CAN WIN · ANYONE CAN RECOMPUTE EVERY HASH IN THE BROWSER
Hedgora replaces “trust the portal” with cryptography: a commitment fixes each price before the deadline, proposals are encrypted in the bidder's browser, and the contract — not a server — decides when anything opens.
01
Sealed by math
Change one digit and the hash no longer matches. Copy someone else's and it fails too.
02
Encrypted proposals
AES-256-GCM in the browser before upload. The key is published only at reveal.
03
Deadlines in code
Phases follow block time. Late bids and early reveals simply revert.

// How it works
From tender to proof in four steps
01
Publish
A buyer posts the scope (on IPFS), budget range and deadlines on-chain.
02
Seal
Bidders commit a hash of their price; proposals are encrypted in the browser.
03
Reveal
After the deadline, bidders open their bids and the contract checks every hash.
04
Prove
The award and a link to its reason are public. Anyone can verify each revealed bid.
Safe by designYour price stays yours
Your price stays yours
Until the deadline says otherwise
Your amount, salt and document key never leave your browser before you reveal. Only the hash goes on-chain and only the encrypted proposal is uploaded — the buyer, the website and the RPC node see nothing readable.
Launch appOnly a hash on-chain
Your salt and key stay in a backup file you download, plus a copy in your browser.
Same rules for every bidder
No one can read a competitor’s price before the submission deadline.
Verifiable by anyone
The results page recomputes each commitment from the revealed values.
