Tether Market Shift

DeversiFi offers its users thick orderbooks with deep liquidity by sourcing liquidity from centralised liquidity providers. 

However, some of the most liquid pairs on centralised exchanges are traded against fiat money, e.g. USD. Unfortunately, fiat money cannot be stored on Ethereum wallets like Metamask.

The implemented solution is to mirror the XXX/USD orderbook, but to use the ERC20 Tether (USDT) on the DeversiFi side to match and settle the orders, while keeping the fiat USD on the centralised side. This allows the user of USDT to match orders created using fiat USD and vice versa.

However the exchange rate of USDT/USD is almost never 1:1, so we adjusted the XXX/USDT price on DeversiFi by the current USDT/USD exchange rate. The price of the pair on DeversiFi therefore appears to be different from the centralised orderbook, but it is effectively the same.
