CREATE OR BROWSE AUCTION
Any wallet can create a sealed-bid auction on BlindBid. Set your item, floor price, duration, and auction type — Vickrey, uniform, or first-price. Bidders browse live auctions and connect their Solana wallet to participate.
ENCRYPT YOUR BID WITH ARCIUM
Enter your bid amount. BlindBid uses Arcium's MPC network to encrypt it client-side before submission. Your bid is split across multiple Arcium nodes — no single node ever sees the full value. The encrypted commitment is then written to Solana.
BIDS SEALED ON SOLANA
All encrypted bids live on-chain as sealed commitments. Anyone can verify that bids were submitted — but nobody, including validators, miners, or other bidders, can read the values. The auction is fully transparent yet completely private.
TRUSTLESS REVEAL & SETTLEMENT
When the auction closes, Arcium nodes jointly compute the result using MPC — decrypting all bids simultaneously without ever revealing individual values to any single party. The winner and price are posted on-chain and settlement is automatic.
