Lower bidsrun longer.
The card auction where you pick how long the clock runs.
Reserve committed on-chain before any bid. Provably fair. Anti-snipe by default.
50% bid → 7 days. 99% bid → 24 hours. The bid % decides the clock.
SHA-256 hash + 32-byte salt anchored on Solana before anyone bids.
A bid in the final 60s extends the clock. No last-second steals.
LIVE SIMULATION
Watch a Lock-In Bid play out.
Card → bid % → clock locks → reserve anchors → live → close → reveal. Switch scenarios below.
THE MATH
Your bid % sets the clock.
Bid low and you get a long window — more time for someone to outbid you, but if nobody does, you steal the card. Bid high and the clock collapses — commit and close.
Long clock = more chances for someone to outbid you. But if nobody does, the card is yours below market.
Short clock = fast commitment. You're close to comp; you're telling the market you want this and you're willing to close it now.
PROVABLY FAIR
We can't move the reserve. You can prove it.
The seller's reserve is committed via SHA-256 hash + 32-byte salt and anchored on Solana before any bid is accepted. Reveal at close. Recompute in your browser. The math is the trust.
Anchored before bid #1
The reserve commit hash is written on Solana before the auction goes live. Once the txn is in the ledger, the seller cannot raise (or lower) the floor.
Hash + salt, not the number
What's anchored is SHA-256(reserve + 32-byte random salt). The number itself is private until close. Pre-image attacks are infeasible.
Verify in one click
At close the reserve + salt are revealed. Every auction page shows the reserve, the salt, and the txn hash so you can recompute the SHA-256 yourself.
