Dollar-pegged stablecoins are an essential component of the crypto world. Traders can use them for a variety of transactions, knowing that the same quantity of stablecoin will have the same purchasing strength no matter what day it is. However, this is a misperception. With the US government and the Federal Reserve control over the US currency, the relentless printing of money happening these recent years certainly make the US dollar's value to fall, resulting in an obvious depreciation of stablecoins.
Our Solution
Dios Finance aims to address this issue by establishing a token backed by a diverse amount of assets and focused on supply expansion as well as control. We believe that DIOS token can maintain its purchasing power in the face of market volatility.

DIOSToken.recoverUnsupported(address,uint256,address) (contracts/DIOSToken.sol#902-905) ignores return value by IERC20(_token).transfer(_to,_amount) (contracts/DIOSToken.sol#904)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

VaultOwned.setVault(address) (contracts/DIOSToken.sol#855-859) should emit an event for:
- _vault = vault_ (contracts/DIOSToken.sol#856)
Emit an event for critical parameter changes.
Additional information: link
VaultOwned.setVault(address).vault_ (contracts/DIOSToken.sol#855) lacks a zero-check on :
- _vault = vault_ (contracts/DIOSToken.sol#856)
Check that the address is not zero.
