DUO is a decentralized, income-generating stable token backed by first-class financial engineering and market proven model. The design of the DUO Network requires a token whose value is implicitly linked to the growth and adoption of the Network. Mechanisms used to reward good behavior and promote expansion need to be tied solely to the success of the Network. A utility token owned by the DUO Network is required. The DUO Network Token is an ERC-20 compatible token issued on Ethereum, with limited supply. It is the primary token used for DUO Network’s smart contracts. DUO contract accepts ether as collateral and takes an ETH/EOS price feed (it’s usually quoted in EOS/ETH but a simple reversion will do the math), can provide Class A Token pegging to EOS value, and Class B Token with leveraged exposure to ETH/EOS price (or from another perspective, a bear leveraged exposure to EOS/ETH price). The DUO concept can be extended beyond price-stable tokens. The flexible design of the smart contract allows collateralized assets being extended from ether to any ERC-20 tokens, and the price feed from any trading pair.
