基本范例  (6)

使用其地址验证 OmiseGo 令牌的总供应量：

Wolfram Language code: omgtoken = First[BlockchainTokenData["OMGToken", "TokenAddress", BlockchainBase -> {"Ethereum", "Mainnet"}]]
Wolfram Language code: BlockchainContractValue[omgtoken, Typed["totalSupply", "uint256"], BlockchainBase -> {"Ethereum", "Mainnet"}]

检查某个持有人的 OMG 令牌余额：

Wolfram Language code: omgtoken = First[BlockchainTokenData["OMGToken", "TokenAddress", BlockchainBase -> {"Ethereum", "Mainnet"}]]
Wolfram Language code: sender = RandomChoice[First[BlockchainTokenData["OMGToken", "TransferList", BlockchainBase -> "Ethereum"]]]["Sender"]
Wolfram Language code: BlockchainContractValue[omgtoken, <|"Function" -> Typed["balanceOf", "address" -> "uint256"], "Inputs" -> sender|>, BlockchainBase -> {"Ethereum", "Mainnet"}]

检查 Token ID 为 883551 的 CryptoKitty 的拍卖情况：

Wolfram Language code: BlockchainContractValue["b1690C08E213a35Ed9bAb7B318DE14420FB57d8C", <|"Function" -> Typed["getAuction", "uint256" -> {"address", "uint256", "uint256", "uint256", "uint256"}], "Inputs" -> 883551|>, BlockchainBase -> {"Ethereum", "Mainnet"}]

调用函数 owner，给出地址：

Wolfram Language code: BlockchainContractValue["9850711951a84ef8a2a31a7868d0dca34b0661ca", Typed["owner", "address"], BlockchainBase -> "Bloxberg"]

获取 USDtz Tezos 通证合约的 storage：

Wolfram Language code: BlockchainContractValue["KT1LN4LPSqTMS7Sd2CJw4bbDGRkMv2t68Fy9", BlockchainBase -> "Tezos"]

用注释获取 USDtz 通证合约的通证总量：

Wolfram Language code: BlockchainContractValue["KT1LN4LPSqTMS7Sd2CJw4bbDGRkMv2t68Fy9", "totalSupply", BlockchainBase -> "Tezos"]
