# Earn from Auction Trade
Souni’s goal is to build the best decentralized NFT trading and auction market on Binance Smart Chain.
Recruit the most well-known hero, equipment, item, and pet by being the no.1 bidder!
Auction Trade is a feature where users are allowed to submit an NFT to bid and sell it to the highest bidder. Through the auction, NFTs will increase in value significantly, seller will receive a commensurate profit, and buyer will receive a highly collectible NFT of great interest.
## Rules
✅ For sellers: Usually NFTs offered for auction will have collectible value such as scarcity, exclusivity, etc. However, other common NFTs can be auctioned as long as you want. The handling fee of 5% of the corresponding currency will be charged for transaction.
✅ For Buyers: Most NFT Marketplaces will not limit or set standards for buyers, everyone can participate in the auction as long as you have enough money to pay for that NFT.
