white paper

Decentralized United (DCU) is building an ecosystem of utilities that will revolutionize Defi. Along with DCU Smart Swap, which gives the unique opportunity for users to receive crypto cash back when using the swap (Trade2Earn), Decentralized United will bring a number of amazing utilities, some of which are unique for the crypto space. DCU Smart Swap, Root Layer Yielding, and Anonymous Bridge are only a small number of use cases that $DCU will build. DCU will have more and more utilities added to the $DCU ecosystem, including a unique smart blockchain, which will make it a one-stop shop for all your Defi needs.

Pragma version^0.8.15 (#9) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.15 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.
