1. Mints the CCCs having the given mintCccs list as being associated with the address present inside the specified wallet. Optionally fee and broadcasting mode parameters can be specified.

   suspend fun mintCccsList(
       mintCccs: List<MintCcc>, 
       wallet: Wallet,
       fee: StdFee? = null,
       mode: BroadcastingMode? = null
   ): TxResponse
   

2. Returns the list of all the ExchangeTradePosition that the specified wallet has minted.

   suspend fun getExchangeTradePositions(
       wallet: Wallet
   ): List<ExchangeTradePosition>
   

3. Burns the CCCs having the given burnCccs list as being associated with the address present inside the specified wallet. Optionally fee and broadcasting mode parameters can be specified.

   suspend fun burnCccsList(
       burnCccs: List<BurnCcc>,
       wallet: Wallet,
       fee: StdFee? = null,
       mode: BroadcastingMode? = null
   ): TxResponse
