}

Fields

payment_token_contract_id: Option<Identifier>

By default, we use a token in the same contract, this field must be set if the document requires payment using another contracts token.

token_contract_position: TokenContractPosition

If we are expecting to pay with a token in a contract, which token are we expecting to pay with? We have this set so contract owners can’t switch out to more valuable token. For example if my Data contract

minimum_token_cost: Option<TokenAmount>

Minimum token cost, this most often should not be set

maximum_token_cost: Option<TokenAmount>

Maximum token cost, this most often should be set If:

• a client does not have this set
• and the data contract allows the price of NFTs to be changed by the data contract’s owner or allowed party. Then:
• The user could see the cost changed on them

gas_fees_paid_by: GasFeesPaidBy

Who pays the gas fees, this needs to match what the contract allows
