Contract functionality is documented here: MetaRegistry

Github

The source code for the MetaRegistry.vy and MetaRegistryL2.vy contracts can be found on GitHub.

Each MetaRegistry is integrated into the chain-specific AddressProvider at ID = 7. To get the most recent contract, users are advised to fetch it directly from the AddressProvider contract.

For example, to query the MetaRegistry contract on Ethereum, one can call get_address(7) on the AddressProvider:

>>> AddressProvider.get_address(7)
'0xF98B45FA17DE75FB1aD0e7aFD971b0ca00e379fC'

Rate Provider

Contract functionality is documented here: RateProvider

Github

The source code for the RateProvider.vy contract can be found on GitHub.

Each RateProvider is integrated into the chain-specific AddressProvider at ID = 18.

For example, to query the RateProvider contract on Ethereum, one can call get_address(18) on the AddressProvider:

>>> AddressProvider.get_address(18)
'0xA834f3d23749233c9B61ba723588570A1cCA0Ed7'
