TWAP and Hybrid Oracles Deployment
Overview
To deploy a standard TWAP Oracle, as well as a hybrid oracle, you can use the TwapOracleFactorySNG
,
Deployment
Deployment of Spectra TWAP oracles as well as the hybrid oracle is done through the deployOracle()
method described below
/**
* @notice Deploys an oracle for a given principal token, pool, and oracle type
* @param _pt The address of the principal token
* @param _pool The address of the pool
* @param _impliedRate The implied rate. Relevant only for hybrid oracles
* 1e18 represents 100%, so for example an implied rate of 30%
*. is represesnted
* @return oracleAddress The address of the deployed oracle
*/
function deployOracle(
address _pt,
address _pool,
uint256 _impliedRate,
OracleType _oracleType
) external returns (address oracleAddress)
It deploys an oracle of _oracleType
for a market composed of a PT of address _pt
and of market address _pool
. The OracleType _oracleType
field allows you to choose the type of oracle you want to deploy. The _impliedRate
field is used exclusively for the Hybrid Oracle and ignored otherwise. The possible types are
enum OracleType {
PTIBT,
PTUND,
YTIBT,
YTUND,
LPIBT,
LPUND,
PTUNDHYBRID
}
The possible types specify the base asset (PT, YT, LP) followed by the quote asset (IBT, Underlying).
