If your blockchain has just been deployed, there is only a genesis account in the blockchain system. You can check the genesis account through the http interface (Example for localhost and 36002):
The value of address in the returned result is the genesis account.
You can query any account through the getAccount interface.

HTTP Interfaces
Generating Public and Private Key pairs - Test
HTTP GET /createKeyPair
CURL command
curlgethttps://{endpoint}/createKeyPair
Function
Note: This interface is only for testing purposes. Do not use this interface in a production environment (SDK or command line used in production environment), because after calling this interface, if the node server is evil, the account's private key will be leaked. This interface only generates a public-private key pair and does not write to the entire network blockchain.

In the design of the smart contract module, we provide a sandbox environment for debugging contracts, and the state of the blockchain and contract is not changed during debugging. On Zetrix, we provide you with the callContract interface to help you debug the smart contract. The smart contract can be stored in the public chain, or it can be tested by uploading the local contract code by parameters. The callContract interface will not be sent. Therefore, there is no need to pay for the transaction fee.

Description
source_address
string
The source account of the transaction, which is the account of the transaction initiator. When the transaction is successful, the nonce field of the source account will be automatically incremented by 1. The nonce in the account number is the number of transactions executed by this account
nonce
int64
Its value must be equal to the current nonce+1 of the source account of the transaction, which is designed to prevent replay attacks. If you want to know how to query the nonce of an account, you can refer to getAccount. If the account queried does not display the nonce value, the current nonce of the account is 0.
fee_limit
int64
The maximum fee that can be accepted for this transaction. The transaction will first charge a fee based on this fee. If the transaction is executed successfully, the actual cost will be charged, otherwise the fee for this field will be charged. The unit is UGas, 1 Gas = 10^6 UGas

Assignment of Control Rights
When you create an account, you can specify the control assignment for this account. You can set this by setting the value of priv. Here is a simple example.
{
"master_weight": "70",//The weight for the private key of this address is 70
"signers": [//The weights assigned
{
"address": "ztxSigpdiWcW22hw54i9PEFk1s4WLEy5Rmh6K",

},
{
"address": "ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo",
"weight": 100 //The weight of the above address is 100
}
],
"tx_threshold": "8",//The weight required to initiate the transaction is 8
"type_thresholds": [
{
"type": 1,//The weight required to create an account is 11
"threshold": 11
},
{//The weight required to issue an asset is 21
"type": 2,
"threshold": 21
},
{//The weight required to transfer assets is 31
"type": 3,

{//The weight required to set metadata is 41
"type": 4,

}
Example
Next, we use ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E to initiate a transaction. This transaction has only one operation, that is, creating a new account ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo, and completing the account creation process by transferring Gas to the new account.
Assembling Transactions
Referring to the structure of Transaction Structure, the following three steps are required:
Obtaining the account nonce value
Assembling operations
Generating transaction objects
Obtaining the Account Nonce Value
In the structure of the transaction, it is necessary to confirm the serial number of the transaction in the transaction initiation account. Therefore, it is necessary to obtain the nonce value of the transaction initiation account through the getAccountBase interface, and increase the nonce value by 1 based on its nonce value.
The interface call is as follows:
HTTP GET https://{endpoint}/getAccountBase?address=ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E
or
curl get https://{endpoint}/getAccountBase?address=ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E
According to the structure of Operations Structure, Operation Codes, and Transferring Gas Assets structure, the json format of the generation operation is as follows:
In Obtaining the Account Nonce Value, the nonce value is 20, then the serial number of the new transaction is 21. According to the operation structure obtained in the Assembling Operations, the json format of the transaction is generated as follows:
This is done through the getTransactionBlob interface.
The interface call is as follows:
HTTP POST https://{endpoint}/getTransactionBlob
or
curl https://{endpoint}/getTransactionBlob -X POST -d "{\"source_address\":\"ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E\",\"nonce\":21,\"fee_limit\":1000000,\"gas_price\":1000,\"operations\":[{\"type\":7,\"pay_coin\":{\"dest_address\":\"ztxSX1SypC33doY4a5MYYr5zBZUvB33kKHdAo\",\"amount\":10000000,\"input\":\"\"}}]}"
Signing signatures is to sign the value of transaction_blob in getTransactionBlob with the private key of ztxSW512jUyDASna878ECgZ4QFyhh6AtEJP6E and generate a public key. For details, please refer to keypair. The resulting signature data is as follows:
According to the signature data obtained by Signing Signatures and the transaction_blob obtained by Serializing Transaction Data, the json format of the body in the submitTransaction interface is generated as follows:
HTTP POST https://{endpoint}/submitTransaction
or
curl https://{endpoint}/submitTransaction -X POST -d "{\"items\":[{\"transaction_blob\":\"0a246275516f50326552796d4163556d33757657675138526e6a7472536e58425866417a7356101518c0843d20e8073a2f0807522b0a24627551747336446654354b6176745639344a675a79373548397069776d62374b6f5557671080ade204\",\"signatures\":[{\"sign_data\":\"ACF64A7D41244AFC4465DBC225D616E0499776140D46BA7A84B1B6B263DAF1422904137E0181301F480F7114EC7CC5BBE4763EDA981E565EF81EF7705596CB0B\",\"public_key\":\"b00168eceea7900ddcb8f694161755f98590ba7944de3bfe339610fe0cacc10a18372dcbf71b\"}]}]}"
According to the hash obtained by the submitTransaction interface, confirm whether the transaction is executed successfully by the getTransactionHistory interface (check whether error_code under transactions is equal to 0).
The interface call is as follows:
HTTP GET https://{endpoint}/getTransactionHistory?hash=3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1
or
curl get https://{endpoint}/getTransactionHistory?hash=3f90865062d7737904ea929cbde7c45e831e4972cf582b69a0198781c452e9e1
