How to transfer trc20 token?
matinaci opened this issue · 6 comments
While we can transfer trc20 tokens via extensions but I could not find a code to transfer by python, do you have any idea?
er20 you can send via contract (trigger_contract)
how?
def SendTRC20(from_address, to_address, contract_address, amount, private_key, fee_limit):
from_address_zeros = (64 - len(from_address)) * "0"
_from_address = from_address_zeros + from_address
to_address_zeros = (64 - len(to_address)) * "0"
_to_address = to_address_zeros + to_address
amount = str(hex((amount)1000000)).replace('0x','')
zeros = (64-len(amount))"0"
amount = zeros + amount
parameter = _to_address + amount
fee_limit = 100000000
data ={"contract_address":contract_address,"function_selector":"transfer(address,uint256)","parameter": parameter,
"fee_limit":fee_limit, "call_value":0,"owner_address":from_address}
data = str(data).replace("""'""",'"')
response = requests.post("https://nile.trongrid.io/wallet/triggersmartcontract", data=data)
res = json.loads(response.content.decode())
transaction = res["transaction"]
private_key = private_key
transaction.pop("visible")
transaction = str(transaction).replace("""'""",'"')
data = {"transaction":transaction,"privateKey":private_key}
response = requests.post("https://nile.trongrid.io/wallet/gettransactionsign", data=str(data))
res = json.loads(response.content.decode())
res.pop("visible")
res = str(res).replace("""'""",'"')
data = res
response = requests.post("https://nile.trongrid.io/wallet/broadcasttransaction", data=str(data))
res = json.loads(response.content.decode())
txid = res["txid"]
return txid
Note : For using this function u have to set address in hexadecimal format.
from_address = string (address which sends the token (example:41E65C21794B63F72076CDCDCBFDFD6570D02FA8C3 ))
to_address = string (address which gives the token)
contract_address = string (token contract address which u use (example : "41c60f4fd695b75c7d6bb3d3a05704ae9ec7f519f7" WIN token))
amount = int (how much u send)
private_key = string (sender private_key)
fee_limit = int
I am using nile testnet so i use this api but in shasta tesnet u have to use https://api.shasta.trongrid.io/wallet/{function_name}
data = {"transaction":transaction,"privateKey":private_key}
response = requests.post("https://nile.trongrid.io/wallet/gettransactionsign", data=str(data))
res = json.loads(response.content.decode())
I keep getting errors in this part.
data = {"transaction": transaction, "privateKey": private_key}
response = requests.post("https://api.trongrid.io/wallet/gettransactionsign", data=str(data))
res2 = json.loads(response.content.decode())
[err]
res2 = json.loads(response.content.decode())
File "/Users/juwonhwang/opt/anaconda3/lib/python3.8/json/__init__.py", line 357, in loads
return _default_decoder.decode(s)
File "/Users/juwonhwang/opt/anaconda3/lib/python3.8/json/decoder.py", line 337, in decode
obj, end = self.raw_decode(s, idx=_w(s, 0).end())

raise JSONDecodeError("Expecting value", s, err.value) from None
json.decoder.JSONDecodeError: Expecting value: line 1 column 1 (char 0)
How can I fix this?
u used the mainnet api but maybe your wallet on testnet? Please check your private key and network then print the response because now u are getting none value
I am trying to transfer the TRC20 tokens on the mainnet to another wallet.

I got this value the first time, but I got an error from the second 'gettransactionsign'.
