Built a sealed-bid auction platform on the Stellar (Soroban) blockchain to eliminate bid sniping and create a fair, decentralized auction experience. The platform uses a commit-reveal mechanism, where bidders first submit a cryptographic hash of their bid during the commit phase and later reveal the actual bid amount once the bidding window closes. This ensures that no participant can view or react to competing bids before the reveal phase, preventing unfair last-minute bidding.

The entire auction process is managed by Soroban smart contracts, which securely escrow bidder funds, verify revealed bids against their original commitments, automatically determine the highest valid bidder, refund unsuccessful participants, and transfer the winning bid to the seller. By removing intermediaries and automating settlement, the platform provides a trustless, transparent, and secure auction system.

The application also features a modern web interface with Stellar wallet integration, allowing users to create auctions, place hidden bids, reveal bids, and track auction results through a seamless user experience.
