Inherits:IFluidOracle, OracleError

Base contract that any Fluid Oracle must implement

State Variables ​

_infoName ​

short helper string to easily identify the oracle. E.g. token symbols

solidity
bytes32 private immutable _infoName;

_targetDecimals ​

target decimals of the oracle when scaling to 1e27. E.g. for ETH / USDC it would be 15 because diff of ETH decimals to 1e27 is 9, and USDC has 6 decimals, so 6+9 = 15, e.g. 2029,047772120364926 For USDC / ETH: 21 + 18 = 39, e.g. 0,000492842018675092636829357843847601646

solidity
uint8 private immutable _targetDecimals;

Functions ​

constructor ​

solidity
constructor(string memory infoName_, uint8 targetDecimals_);

targetDecimals ​

target decimals of the returned oracle rate when scaling to 1e27. E.g. for ETH / USDC it would be 15 because diff of ETH decimals to 1e27 is 9, and USDC has 6 decimals, so 6+9 = 15, e.g. 2029,047772120364926 For USDC / ETH: 21 + 18 = 39, e.g. 0,000492842018675092636829357843847601646

solidity
function targetDecimals() external view returns (uint8);

infoName ​

helper string to easily identify the oracle. E.g. token symbols

solidity
function infoName() external view returns (string memory);

getExchangeRate ​

Deprecated. Use getExchangeRateOperate() and getExchangeRateLiquidate() instead. Only implemented for backwards compatibility.

solidity
function getExchangeRate() external view virtual returns (uint256 exchangeRate_);

getExchangeRateOperate ​

Get the exchangeRate_ between the underlying asset and the peg asset in 1e27 for operates

solidity
function getExchangeRateOperate() external view virtual returns (uint256 exchangeRate_);

getExchangeRateLiquidate ​

Get the exchangeRate_ between the underlying asset and the peg asset in 1e27 for liquidations

solidity
function getExchangeRateLiquidate() external view virtual returns (uint256 exchangeRate_);
