NEM SDK for Python3!

トランザクション生成用のJSONをcreateTransaction関数に渡すとバイト文字列が返ってきます。それをsignTransaction関数で処理すると署名データが得られます。ここまでをオフラインで実行できます。最後にオンライン環境でannounceTransaction関数でアナウンスすればトランザクションがブロックチェーンに記録されます。モザイク作成時のlevyとメッセージの暗号化は未実装です。

テスト用としてのみ使用してください。このコードによって損害が生じても責任は負いかねます。

実行例(トランスファートランザクション)

  • インポート --- import
import nempy
  • トランザクション作成 --- create transaction
params = {
	"transaction":
	{
	    "timeStamp": nempy.getTimeStamp(),
	    "amount": int(0.3*1000000),
	    "fee": int(0.15*1000000),
	    "recipient": "TC4WKOGT6V2B6O5LKBMBMBC6UBIARCSX7R4WPJCV",
	    "type": nempy.TransactionType.transfer_transaction,
	    "deadline": nempy.getTimeStamp(delta=3600),
	    "message":
	    {
	        "payload": "hello",
	        "type": 1
	    },
	    "version": nempy.Version.test,
	    "signer": "f0d94bcdc9aa20f893f22b84896959c4f87947c8d52acee92762afe8363364f3",
	    "mosaics":[
	    {
	        "mosaicId":{
	            "namespaceId": "nem",
	            "name": "xem"
	        },
	        "quantity": 100000
	    }
	    ]
	}
}
        
data = nempy.createTransaction(params)
  • 署名 --- sign transaction
signed_data = nempy.signTransaction(data, pvtkey="1411c9ff8dda47053133eeed943ea0365e81876b381fb205abc2aa391d6ad499")
  • アナウンス --- announce signed transaction
r = nempy.announceTransaction(signed_data, nis="http://23.228.67.85:7890")
  • 結果の確認 --- check result
print(r.json())

{
	"innerTransactionHash": {},
	"code": 1,
	"type": 1,
	"message": "SUCCESS",
	"transactionHash": {
		"data": "84792a6e23a8a4d1b889b5c60fcf248c91519da2e54aba6ab3d4af1096ce700a"
