cannot get abi from etherscan contract

cannot get abi from etherscan contract - python

I am trying to compare the balance of address1 which I am printing out normally with the total supply of the tokens in address 2. In order to get the total supply I have to get the ABI of the contract and check the value of the total supply function.
For some reason I am unable to get the ABI of address 2 and it is not giving me any errors. The if statement at the end is just to check that one is less than the other

web3py with 0x API

I have been trying to perform a swap on Ropsten using the 0x API to get the best quote but every time I try to perform a swap the transaction fails without any feedback(at least from Etherscan) while the approve tx goes through fine.
I am probably missing something here, but I'm getting blind to keep staring at my code.

print(w3.toHex(tx_hash))
# Use only for testing the query
getQuote(DAI, slippage, USDC, sellAmount)
As you can see I am trying to swap USDC for DAI using the 0x API.
The first tx generated is approved
Etherscan approval tx
But the actual swap fails without any feedback
Etherscan swap tx
I honestly don't know what to try anymore...I've been digging both documentation and reading anything I could find on Stackoverflow without any luck.
Any help is greatly appreciate.

web3 python getAmountsOut execution reverted

I managed to set up this function that returns the token value in USD of a contract, everything works fine in some contracts, but in other contracts I get the error "execution reverted" when calling the function "getAmountsOut" does anyone have any idea what it can be? I get the contracts from the same place in bscscan and for some it works and for some it doesn't.
bsc = 'https://bsc-dataseed.binance.org/'
web3 = Web3(Web3.HTTPProvider(bsc))
panRouterContractAddress = '0x10ED43C718714eb63d5aA57B78B54704E256024E'
panabi = '[{...}]'

def get_price(self):
try:
# Base currency token instantiate and ABI
baseCurrency = web3.toChecksumAddress("0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56") # BUSD
# get symbol token
sellTokenContract = web3.eth.contract(self.token_to_buy, abi=sellAbi)
symbol = sellTokenContract.functions.symbol().call()
# Selling token instance and contract
tokenToSell = web3.toChecksumAddress(self.token_to_buy) # TOKEN PRICE
sellAmount = web3.toWei(1, 'ether')
# Calculate minimum amount of tokens to receive
amountOut = contractbuy.functions.getAmountsOut(sellAmount, [tokenToSell, baseCurrency]).call() # Error here
amountOutMin = web3.fromWei(int(amountOut[1]), 'ether')
print("Valor do token: ", str(amountOutMin))
str_format = "{:." + self.decs_usd + "f}"
return float(str_format.format(amountOutMin)), symbol
except Exception as ex:
print("ERRO:ver_preco:", ex)
return "", ""

https://bscscan.com/address/0xe786d5a4b985bfe5e371f8e94413cfb440f6618a
if anyone can explain to me why this error occurs in some tokens and not others, and how I can get error message details besides "execution reverted"

The latter specified token addresses fail with the error because there is no existing Pancakeswap pair contract for the specified address combination.
Another way of checking the existence of a pair contract is by calling the factory's getPair() function.
// returns the existing pair contract address 0x5f7A2a0A32C0616898cA7957C1D58BC92a7E2f6f
getPair(
// ZDC token specified in your question as OK
"0x5649e392A1BAC3e21672203589aDF8f6C99f8dB3",
// BUSD
"0xe9e7CEA3DedcA5984780Bafc599bD69ADd087D56"
)
// returns the zero address 0x0000000000000000000000000000000000000000
// because there's no pair contract for these specified tokens
getPair(
// DGZV token specified in your question as NOTOK
"0x9376E6B29b5422f38391A2a315623cB853c3c68e",

How to filter ETH transactions by address with web3.py

Is there a way to filter transactions by address?
I have tried to do that with matching address with transaction dict key-value pairs ('from', 'to') but it takes too long. Is there a way to do that faster?
For example it takes more than 1hour to analyse last 5000 blocks.
from web3 import Web3
from datetime import datetime
# Defining url for collecting ETH transactions
infura_url = "https://mainnet.infura.io/v3/xxxxxxxxxxxx"
# Making connections with infra url
web3 = Web3(Web3.HTTPProvider(infura_url))
print("Connection is successful:", web3.isConnected())
# Wallet Address
account = "0xaa7a9ca87d3694b5755f213b5d04094b8d0f0a6f"
# Checking the balance for that address (in WEIs)
try:
print("Input Address:", account)
balance = web3.eth.getBalance(account)
except:
# If its not a lowercase()
account = Web3.toChecksumAddress(account)
print("Input Address:", account)
balance = web3.eth.getBalance(account)
# Print balance in WEIs
print("Balance in WEIs:", balance)
# Converting account balance to ETH
balanceWEI = web3.fromWei(balance, "ether")
print("Balance in ETH:", balanceWEI)
# Defining start block and latest block
start_block = web3.eth.blockNumber-5000
end_block = web3.eth.blockNumber
for block_num in range(start_block, end_block):
current_block = block_num
# Get block with specific number with all transactions
block = web3.eth.getBlock(block_num, full_transactions=True)
list_of_block_transactions = block.transactions
for transaction in list_of_block_transactions:
to_account = transaction['to']
from_account = transaction['from']
if to_account == account:
print("To account:", to_account)
to_match = True
else:
to_match = False
if from_account == account:
print("From account:", from_account)
from_account = True
else:
from_account = False
if to_match == True or from_account == True:
print("Found Transaction with HASH:", transaction['hash'])
print("Found Transaction with HASH-HEX:", transaction['hash'].hex())
print("Found Transaction with value:", transaction['value']) # this value is always 0
print("Found Transaction with gas:", transaction['gas']) # this value is more than 0
print()
For example, if my address is:
# Wallet Address
account = "0xaa7a9ca87d3694b5755f213b5d04094b8d0f0a6f"
How can I get only blocks were transaction with that address exists (transaction from that address or to that address)?

getAmountsOut() function with Web3.py returns wrong amount

I'm stuck between a rock and a hard place on this one. When trying to sell a token, I ran getAmountsOut() function and got the wrong value of BUSD that I'm supposed to receive (cross-checked on pancakeswap with slippage = o%). About 100 BUSD less every time. However, I get the right value when trying to buy a token with BUSD. Any ideas on what to do? Thanks in advance!

What causes memory leak in this function

Memory leak
I have this function volumeCounter() that is in a loop (in function looper())that executes every 10 sec. It is receiving data via api. After that it stores it into a sqlite database. When ran for a few hours, the ram will rise. It is especially noticeable when there are 100 threads or more of this function running (one thread for each market like BTC-ETH). After commenting it out, memory usage did not rise.
My question is, what inside this function is causing memory to rise.
def volumeCounter(self):
pass_to_table = api.get_market_history(self.market, 100)["result"] #This is in json format.
for i in pass_to_table:
id_i = i['Id']
time_i = i['TimeStamp'].replace("T", " ")
type_i = i['OrderType']
total = i['Total']
price = i["Price"]
self.cursor.execute(
"""INSERT OR IGNORE INTO {} (id, price, total, type,time) VALUES(?,?,?,?,?)""".format(
self.table_prices), (id_i, price, total, type_i, time_i))
self.connection.commit()
Function looper() that is looping volumeCounter(). It is executed in __init__() at start.
Script looks like this:
key = 'public_key'
secret = 'secret_key'
api = Bittrex(key, secret)
class CryptoScanner:
def __init__(self, market, interval, mailAdrr, mailPass, volume):
# Spremenljivke
self.market = market
self.timeInterval = interval
self.path = "ann{}/{}".format(interval, market)
self.path_2 = self.market.replace('-', '_')
self.database = "{}/{}.db".format(self.path, self.path_2)
self.mailAdrr = mailAdrr
self.mailPass = mailPass
self.sez_length = 0
self.volume = volume
self.scan_mode = False
# Table names
self.table_prices = '{}_prices'.format(self.path_2)
self.table_prices_sum = '{}_prices_sum'.format(self.path_2)
self.table_volume = '{}_volume'.format(self.path_2)
self.table_volume_change = '{}_volume_change'.format(self.path_2)
self.looper()
Then the class object is made for every market with multithreading.
for i in api.get_market_summaries()['result']:
if "BTC" in i['MarketName'] and i['BaseVolume'] >= lower_boundary and i['BaseVolume'] <= upper_boundary:
string = i['MarketName']
d["{}".format(string[4:])] = "{}".format(i['MarketName'])
volume["{}".format(string[4:])] = i['BaseVolume']
threads = []
for i in d:
t = threading.Thread(target=CryptoScanner, args=(d[i], interval_sec, mail, password, volume[i]))
threads.append(d)
t.start()
print("Created thread {}".format(d[i]))
