| alias | string | No | Contract alias when deploying a new contract to facilitate identification of different contracts. |
| note | string | No | notes for this transaction |
| amount | uint64 | No | When the contract is invoked, if the amount needs to be passed, pass this parameter. |
| fee | int64 | No | Your handling fee for this transaction, needs to be about the gas value *gasPrice of contract consumption |
| gasPrice | uint32 | No | unit gas pricing, default is 1 |

The EVM contract has two identifiers, one is contract address, the other is contract name, and they are the unique one-to-one correspondence. Due to the system design, the contract name must be used to operate the transfer operation, so this interface provides the mutual checking ability of the two.
