Themis ⚖

An oracle enabling Purchasing Power Parity on Ethereum to allow for a more equitable and dynamic pricing of products allowing you to send and receive payments normalized to the geolocation of the users.

Oracle Details

Response Schema

{
    0: string: ccIsoAlpha2
    1: string: ccIsoAlpha3
    2: uint256: exchangeRate
    3: uint256: ppp
    4: uint256: pppConversionFactor
}

Response Example

{
    'ccIsoAlpha2': 'IN',
    'ccIsoAlpha3': 'IND',
    'exchangeRate': 74929300,
    'ppp': 185530,
    'pppConversionFactor': 247606743957303,
}

Response Details

ℹ All baselines are in USD.

  • countryCodeIsoAlpha2 : This is the ISO Alpha 2 Standard Country Code. You can find the available country codes below.

  • countryCodeIsoAlpha3 : This is the ISO Alpha 3 Standard Country Code. You can find the available country codes below.

  • exchangeRate : Exchange rate of the currency vs USD. ℹ️ The original value is multiplied by (10^6) and returned by the contract. This is done to allow storing decimals on Ethereum.

  • ppp : This is the Purchasing Power Pairity. ℹ️ The original value is multiplied by (10^4) and returned by the contract.

  • pppConversionFactor : The exchangeRate and ppp property are used to compute the pppConversionFactor. ℹ️ The original value is multiplied by (10^15) and returned by the contract.
