Auction in a SAFU all-in-one place to cut any NFT deal in a few clicks. Mobile, decentralized, blockchain-based.

OpenBiSea NFT marketplace is a smart contract, and iOS, Android and web UI app. It's a simple, step-by-step guided solution to buy, sell and make auctions (smart contract based) for NFT. The main core smart contracts are built on the Binance Smart Chain (BSC), polygon(exMATIC) and have an Ethereum bridge for NFT assets.

OpenBiSea is First easiest way to invest and manage your NFT.

How often have you been confused while using any crypto apps? For me the answer is: too often. Now on the market, to start with NFT, you have to: download a crypto wallet purchase crypto money there go to NFT marketplace website and connect the wallet to your account purchase NFT there and one more thing… you can not sell those NFTs in other marketplaces. OpenBiSea is an all-in-one mobile app where you can do all the above in a few clicks.

OpenBiSea - bridge between Ethereum and Binance Smart Chain Bridge smart contracts deployed in Ethereum blockchain can hold Ethereum-based NFTs and create the same NFTs on Binance Smart Chain. You can perform the same operation back. All NFT assets flow transparently and results appear automatically and are stored unchanged in the blockchain. This is the way to trade NFTs without high Ethereum fees but with the same ownership value on Ethereum.

Why blockchain? The existing marketplaces are not transparent enough. A human factor can result in manipulations with funds valuation. INVESTORS see a NFT value directly in blockchain before investing invest money to the NFT in one transaction check each NFT valuation 24/7 directly from blockchain verify investments value, growth rate 24/7 get OBS tokens based on blockchain smart contract logic CREATORS list NFT tokens and open auctions cancel auction at any time are sure that anybody can purchase with the highest price, based on smart contract logic get OBS tokens batch based on blockchain smart contract logic REFERRALS (people, who refer OpenBiSea to investors) Safe receipt of interest from invested money and OBS tokens based on blockchain smart contract logic
