Smart Contract Auction Platform

Why Choose This Project?

Traditional online auctions are centralized, opaque, and prone to manipulation, with delays in payment and item transfer. This blockchain-based auction platform leverages smart contracts to automate bidding, payments, and ownership transfer. It ensures transparent, secure, and tamper-proof auctions, where participants can trust that rules are enforced automatically without intermediaries.
