Premium items up for sealed bidding
Crypto trusted privacy infrastructure. Try sealed auctions and experience true bid privacy.
Bids sealed with multi-party computation — no one sees your bid until the auction ends.
Fast confirmations and near-zero transaction fees for every auction interaction.
Trustless privacy layer for encrypted computation on-chain.
Winner pays second-highest bid — honest bidding is always rewarded.
When you place a bid, it is encrypted using Arcium's MPC protocol before being submitted on-chain. The encrypted bid is stored in a way that only the final auction resolution can reveal. This prevents front-running, bid sniping, and any form of bid manipulation.

“ArcBid finally makes on-chain auctions fair. No more front-running, no more bid sniping. Just pure encrypted competition. The Vickrey auction format combined with MPC encryption is a game-changer.”
