banksy-contract

Banksy smart contracts. several blockchain networks that will be added over time: first Ethereum then Solana, Polkadot, Binance , Tron, EOS etc.

Packages

The folders distinguish between different functional Packages

exchange_contract the contracts used to implement the trade
lend_contract the contracts used to mortgage NFTs to lend ERC20 tokens
split_contract the contracts used to split the NFT to ERC20 token
tutorials Some tutorials shared in internal development

NFT Storage

The data information and metadata of NFTs ( maybe images, videos, etc. ) is stored on the IPFS. Then, the Link to the metadata would be uploaded to the NFT contract as the uri, and keep permanently on Ethereum.

In terms of technology selection for IPFS implementation, we finally chose Filecoin IPFS after extensive market research.

NFT exchange

The exchange is completed in cooperation with on-chain and off-chain for gas efficiency. The whole process is as follows:

The seller sign a order that describe the information for sale about the NFT, the order and signature will be save off-chain. Then the sale will be showed on our website. the buyer also need to sign a order when select the NFT to purchase. Then the signs and orders of buyer and seller will be upload to exchange contract, and the transation will be perform on on-chain


banksy合同

银行智能合约。随着时间的推移,将添加几个区块链blockchain网络:首先是以太坊eth,然后是Solana、Polkadt、Binance、Tron、EOS等。

NFT存储

文件夹区分不同的功能包。

Package Description
NFT交换合同 用于存储NFT的合同
分割合同 用于将NFT分割成ERC20代币的合同
教程 一些教程在内部开发中共享
split_contract the contracts used to split the NFT to ERC20 token
tutorials Some tutorials shared in internal development

NFT交换

NFT的数据信息和元数据(可能是图像、视频等)存储在IPF上。然后,元数据的链接将作为uri上传到NFT合同,并永久保留在以太坊eth

在IPFS实施的技术选择方面,经过广泛的市场调研,我们最终选择了Filecoin IPFS

NFT exchange

为了提高气体效率,与链上和链外合作完成交换。整个过程如下:

卖家签署一份订单,描述NFT的销售信息,订单和签名将保存在链外。然后在我们的网站上展示销售情况。在选择NFT进行购买时,买方还需要签署订单。然后将买卖双方的签字和订单上传到交换合同中,交易将在链上执行
