TWAP Oracles Deployment

Overview

To deploy a standard TWAP Oracle, you can use the TwapOracleFactoryNG and TwapOracleFactorySNG , depending on whether your underlyiong market usestwocrypto-ng or stableswap-ng AMMs.

Deployment

Deployment of Spectra TWAP oracles is done through the deployOracle() method

    /**
     * @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 _oracleType The type of oracle
     * @param _initialOwner The address of the initial owner of the oracle
     * @return oracleAddress The address of the deployed oracle
     */
    function deployOracle(
        address _pt,
        address _pool,
        OracleType _oracleType,
        address _initialOwner
    ) 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 possible types are

enum OracleType {
        PTIBT,
        PTUND,
        YTIBT,
        YTUND,
        LPIBT,
        LPUND
    }

The possible types specify the base asset (PT, YT, LP) followed by the quote asset (IBT, Underlying).

Setting yourself as the _initialOwner allows you to upgrade the oracle implementation.

Deployment can be done through the common interface ITwapOracleFactory , since both TwapOracleFactoryNG and TwapOracleFactorySNG both implement it.
