All Bids Sealed.
Until the Gavel Falls.
Bids are encrypted client-side and processed by Arcium's MPC cluster. Nobody — not even the auctioneer — can see competing bids until the auction closes.
Solana Genesis
Collection #001
A landmark piece from the founding era of Solana's NFT ecosystem. Historically significant and cryptographically rare. Bidding closes in:
Blind by Design.
Not by Promise.
Traditional auctions expose bids on-chain, enabling sniping and collusion. StealthBid uses Arcium MPC to make bid privacy a cryptographic guarantee.
Confidential
computing for
fair auctions
Arcium is a parallelized confidential computing network on Solana. It enables computation over encrypted data — so the auction settlement logic runs without any party seeing the bids.
StealthBid uses Arcium's MXE (Multiparty Execution) environment to run winner determination over sealed bid ciphertexts. The result is mathematically guaranteed blind auction — not just a policy.
Losing bidders never have their amounts revealed. MEV bots have nothing to front-run. Colluding bidders cannot coordinate because no bid is visible during the auction window.
No Sniping
Bidders cannot react to others' bids because no bid amounts are visible during the auction window.
No Collusion
Bidder rings cannot coordinate because there is no information to coordinate on — all bids are sealed.
No MEV Leakage
Validators and searchers cannot extract value from bid information — there is none to extract.
