how can we get all the past events of the contract ?
I am trying like this :

on web3.js ( "web3": "^1.0.0-beta.34"):

// Add the web3 node module
var Web3 = require('web3');

// Show web3 where it needs to look for the Ethereum node.
web3 = new Web3(new Web3.providers.WebsocketProvider('wss://mainnet.infura.io/_ws'));

// Define the contract ABI
var abi =

// Define the contract ABI and Address
var contract = new web3.eth.Contract(abi, '0x5a3c9A1725BB82690ee0959c89abE96fD1b527ee');

// Fun console text, you can ignore this.
console.log('-----------------------------------');
console.log('Matching Smart Contract Events');
console.log('-----------------------------------');

const filter = { fromBlock: 0, toBlock: 'latest'}; // filter for your address
const events = contract.allEvents(filter); // get all events
console.log(events)

// contract.Transfer({}, { fromBlock: 0, toBlock: 'latest' }).get((error, eventResult) => {
// if (error)
// console.log('Error in myEvent event handler: ' + error);
// else
// console.log('myEvent: ' + JSON.stringify(eventResult.args));
// });

// contract.allEvents(fromBlock: 0, toBlock: 'latest', (e, res) => console.log(res))
on web3.py (web3==4.3.0) :


import requests
from web3 import Web3,WebsocketProvider

def main():
web3 = Web3(WebsocketProvider("wss://mainnet.infura.io/_ws"))
print (web3, "web3")
contract_address = "0x5a3c9A1725BB82690ee0959c89abE96fD1b527ee"
contract_abi =
contract = web3.eth.contract(address=contract_address, abi=contract_abi)
print (contract, "contract")

transferEvent = contract.eventFilter('Transfer', {'fromBlock': 0,'toBlock': 'latest'});
print (transferEvent, "transferEvent")

eventlist = transferEvent.get_all_entries()
print(eventlist, "eventlist")


# transferEvent = contract.eventFilter('Transfer', fromBlock = 0)
# transferEvent = contract.events.Transfer.createFilter(fromBlock = 0)
# print (transferEvent.get_all_entries())

if __name__ == "__main__":
print ("Script has started...")
main()
print ("Script has ended...")
