ERC1155 Token

ERC1155Token

Implements the ERC1155 token standard for transferring fCash tokens within Notional. ERC1155 ids encode an identifier that represents assets that are fungible with each other. For example, two fCash tokens that asset in the same market and mature at the same time are fungible with each other and therefore will have the same id. CASH_PAYER tokens are not transferrable because they have negative value.
