Arche network is a User-Defined Financial Contract Open Platform that committed to developing a user-friendly non-standard marketplace for customized transactions. It allows users to customize their financial contracts on the blockchain without doing any coding. In the traditional financial market, customized financial products require strong institutional endorsement and a high cost of operation. Behind such strong credit is a trillion-dollar financial market that is beyond the reach and participation of ordinary people. On the contrary, through smart contracts, we can customize the financial products with low cost and barriers. The cost of setting up and operating a financial contract generated through smart contracts is almost zero. There is almost no risk in the operation of such a product, the only risk is its basic blockchain framework(i.e. Ethereum network or Binance smart chain). On Arche, you can customize your own financial contract. After you set the relevant parameters and deposit the asset, a trigger condition or oracle will be provided by the contract to complete the transaction. You can also bring your financial products to the market quickly through the composability of other Defi protocols. There are more and more innovative and creative people join the blockchain industry and together build up this Lego-style Defi empire and contribute to the world of decentralized finance. Arche protocols will empower traders and developers to participate in the customized financial marketplace and provide user-friendly tools and community support.
