About

Provides an on-chain list of ilk types in the DSS system.

Useful for external contracts or web frontends which need to iterate over the on-chain ilk types and/or access information about a particular ilk.

• Modify the registry

  • add(address joinAdapter): Add a new ilk to the registry by passing the Join Adapter address. The adapter must be live on mainnet and can not already be included in the registry.
  • remove(bytes32 ilk): Remove an ilk from the registry if it's adapter has been caged.
  • update(bytes32 ilk): Update the flip and pip contracts in storage for a given ilk.

• Get information from the registry

  • list(): return a bytes32[] of available ilk types.
  • list(uint256 start, uint256 end): returns a bytes32[] of a portion of the complete list.
  • get(uint256 pos): get the bytes32 ilk type from an indexed position in the array.
  • info(bytes32 ilk): return information about an ilk
    • name: token name (string)
    • symbol: token symbol (string)
    • class: classification code of the ilk (uint256)
    • dec: token decimals (uint256)
    • gem: token address
    • pip: price feed
    • join: token join adapter
    • flip: ilk flipper
  • count(): return number of ilks as uint256
  • pos(bytes32 ilk): the location in the ilks array for this ilk
  • gem(bytes32 ilk): the address of the ilk's token contract
  • pip(bytes32 ilk): the address of the ilk's pip contract
  • join(bytes32 ilk): the address of the ilk's join adapter
  • flip(bytes32 ilk): the address of the ilk's flipper contract
  • dec(bytes32 ilk): the number of decimals for an ilk as uint256
  • name(bytes32 ilk): the name of the token (if available) as string
  • symbol(bytes32 ilk): the token symbol (if available) as string

• auth functions (available to MakerDAO governance)

  • file(bytes32 what, address): Update core contract values
  • file(bytes32 ilk, bytes32 what, address): Update ilk data values
  • file(bytes32 ilk, bytes32 what, uint256): Update ilk data values
  • file(bytes32 ilk, bytes32 what, string calldata): Update ilk data values
  • rely(address) and deny(address): configure auth users
  • removeAuth(bytes32 ilk): remove an uncaged ilk adapter
