Enabling the SCT(Symverse Contract Template) APIs

SCT uses write and get methods differently. In the case of recording, a generic transaction is generated to process the SCT and the stored contract can be confirmed via the next (# JSON-RPC SCT).

To offer these APIs over the Gsym RPC endpoints, please specify them with the --${interface}api command line argument (where ${interface} can be rpc for the HTTP endpoint, ws for the WebSocket endpoint and ipc for the unix socket (Unix) or named pipe (Windows) endpoint).

For example: gsym --ipcapi sct --rpcapi sct --wsapi sct --ws --rpc

Enables the official sct API over the IPC interface
Enables the official sct API over the HTTP interface
Enables the official sct API over the WebSoket interface

The HTTP RPC interface must be explicitly enabled using the --rpc flag.

SCT20

SCT20 is a template that implements ERC20 Interface. You can use the same features as Total Supply, Transfer, Balance Of, Transfer From, and Approve.

SCT20_CREATE

Create an SCT20 contract.

Type : 20
Method : 0
Parameters :
1. Name: STRING - Contract(Token) Name
2. Symbol: STRING - Contract(Token) Symbol. The length should be from 3 to 10.
3. Amount: QUANTITY - Total Supply
4. Owner: DATA, 10 Bytes - address of the contract owner.

Example

// Create SCT20 Token whose name is "SymToken" and 
// symbol is "STK" and 
// total supply is 100 * 10^18 STK (="0x56bc75e2d63100000") and 
// contract owner is "0x00020000000000070002"
// Get SCT rlp encoded string
