Add immediate purchase capability alongside traditional bidding, giving sellers flexibility to offer instant sale options while maintaining auction dynamics. Key features: - Optional buy-now-price parameter in create-auction (0 = disabled) - buy-it-now function for instant purchases at fixed price - Automatic deactivation after first bid received - Separate tracking: buy-now-volume global and buy-now-purchases per user - buy-now-price must be >= starting-price (validation) - Buy now unavailable for seller's own auctions New data structures: - auctions.buy-now-price: uint (0 = disabled) - user-bids.buy-now-purchases: uint - buy-now-volume global counter New functions: - buy-it-now (public): Execute instant purchase - is-buy-now-available (read-only): Check availability - get-buy-now-price (read-only): View current price - generate-buy-now-receipt: Purchase confirmation Events & Logging: - log-buy-now event for purchase tracking - Enhanced auction-created event with buy-now-price - Updated user stats tracking for buy now purchases Error handling: - ERR_BUY_NOW_UNAVAILABLE (u6010): Buy now not available - ERR_BUY_NOW_EXPIRED (u6011): Beyond auction end - ERR_BUY_NOW_ALREADY_SOLD (u6012): Already purchased - ERR_INVALID_BUY_NOW (u6013): Price < starting-price This enhancement provides instant liquidity option while preserving traditional auction mechanics, improving user experience and market efficiency.
