Config is a central contract for NUTS Platform configurations. Currently, it can be only updated by NUTS Platform admins. A more community-driven solution might come in the future release.

Config provides the following configurations:

• Address of Wrapped ETH token

  • All Instrument Escrows share the same Wrapped ETH token contract

  • Instrument Escrows convert ETH into Wrapped ETH token when user deposits ETH, and convert Wrapped ETH token into ETH when user withdraws ETH

  • All Instrument Managers share the same Escrow Factory to create Instrument Escrow and Issuance Escrow
