"details": "ConverterBase The converter contains the main logic for conversions between different ERC20 tokens. It is also the upgradable part of the mechanism (note that upgrades are opt-in). The anchor must be set on construction and cannot be changed afterwards. Wrappers are provided for some of the anchor's functions, for easier access. Once the converter accepts ownership of the anchor, it becomes the anchor's sole controller and can execute any of its functions. To upgrade the converter, anchor ownership must be transferred to a new converter, along with any relevant data. Note that the converter can transfer anchor ownership to a new converter that doesn't allow upgrades anymore, for finalizing the relationship between the converter and the anchor. Converter types (defined as uint16 type) - 0 = liquid token converter 1 = liquidity pool v1 converter 2 = liquidity pool v2 converter Note that converters don't currently support tokens with transfer fees.",
