- Must have a
D'CENT Biometric wallet
. You can get it at D'CENT website : https://dcentwallet.com/Shop - D'CENT Biometric will be connected with your PC or Labtop using USB Cable(Micro USB 5-pin type).
All API functions return a
Promise
.
When function processing is completed, it is resolved. If an error occurs, it is rejected.
In either case, respond with a JSON object.{
"header": {
"version": "1.0",
"request_from": "",
"status": ""
},
"body": {
"command" : "",
"parameter" : {}
}
}
If D'CENT wallet isn't connected via USB, you'll get the following error:
{
"header": {
"version": "1.0",
"request_from": "wam",
"status": "error"
},
"body": {
"error": {
"code": "no_device",
"message": "D'CENT Biometric Wallet is not connected"
}
}
}
When executing a function that requires user authentication, an error occurs if the user cancels the authentication. The following shows the user cancel error in the Ethereum signed Transaction.

"request_from": "ethereum",
"status": "error"
},
"body": {
"command": "transaction",
"error": {
"code": "user_cancel",
"message": "user cancel"
}
}
}
dcent-cli-connector
provides functions for using D'CENT Biometric Wallet.var result
try{
result = await DcentCLIConnector.info()

Sets the maximum time the function will run. Once set the timeout Time, it is valid until the value is set again. The default value is 60 seconds.
You can set the timeout time by calling
setTimeOutMs ()
as shown below.
try {
await DcentCLIConnector.setTimeOutMs(60000) // 60 sec, The default value is 60 seconds.
} catch (e) {
console.log(e)
}
All functions except setTimeOutMs function are called and then respond with
