hello noob question,

is it possible to do this type of thing

1) save msg.sender to private variable as "previous msg.sender" / to-be used for validation
2) save block.number or block.timestamp as "previous block.number or block.timestamp" / to-be used for validation

working on related to token development specific during transfers

i want to try and setup a contract to auto-ban those using those trading bots/snipers

Jul 18, 2021, 10:44 AM

not worth trying

as it would have false positives

99% of the time

Jul 18, 2021, 10:48 AM

T_T just when i finally got the idea so it might be a bad try

bec i got data how it behaves, multiple buys in same block.number or timestamp

coming from the same msg.sender but if it could have false positive then forget it lmao

Jul 18, 2021, 10:50 AM

you could do that

Jul 18, 2021, 10:54 AM

i dont know how to write it though

just the idea will study more

Jul 18, 2021, 10:55 AM

uint256 private lastTimestamp;
address private lastSender;

modifier toNotBeCalledAgain {
require (_msgSender() != lastSender && /* or || */ lastTimestamp != block.timestamp);
lastTimestamp = block.timestamp;
lastSender = _msgSender()
_;
}

@bronersick

only problem is, that it would add a lot more gas

and it is probably not worth it

like 40k per function call

Jul 18, 2021, 10:58 AM

shitt

the idea is to put the saving of previous timestamp/block/sender after it made a first txn, the validation in transfer is the second step

so it needs to pass first then do this modifier, then save information and then when it does a transfer again there it auto-bans

but if it requires 40k thats not worth it

Jul 18, 2021, 11:00 AM

depends, if you want it to only check block.timestamp it could cost 20k

if you don't want a contract to call the function multiple times

Jul 18, 2021, 11:01 AM

yeah i think block.timestamp works bec its impossible to make multiple txn in the same timestamp

Jul 18, 2021, 11:01 AM

if thats what you want

Jul 18, 2021, 11:01 AM

for human it is impossible*

though i dont understand how modifiers are called

are they like the ones you call in read or write

Jul 18, 2021, 11:02 AM

uint256 private lastTimestamp;

modifier toNotBeCalledAgain {
require (lastTimestamp != block.timestamp);
lastTimestamp = block.timestamp;
_;
}

function doSomething() external modifierHere {}

Jul 18, 2021, 11:02 AM

so its like a condition before performing the function

so i dont have to put code inside the function

Jul 18, 2021, 11:03 AM

ye before or after

Jul 18, 2021, 11:03 AM

wow got it easily understood

Jul 18, 2021, 11:03 AM

modifer After {
_;
// do something after
}

Jul 18, 2021, 11:03 AM

modifier lockTheSwap {
inSwap = true;
_;
inSwap = false;
}

for example brother, if this is the code for the modifier

its default to true right

code after _; - is something i dont get

where it says below inswap = false

Jul 18, 2021, 11:06 AM

when the function starts, inswap is set to true

on end it is set to false

Jul 18, 2021, 11:10 AM

and when it ends it goes back to false?

Jul 18, 2021, 11:10 AM

yes

Jul 18, 2021, 11:10 AM

wow ok

thank you

so these modifiers are interesting

Jul 18, 2021, 11:10 AM

then me too :P

just copy and paste

actually, i made a contract which doesn't need copy and paste

just calling a function

the only good thing its good at is testing small pieces of code

well if a token locker pays well

i might make one myself :P

Jul 18, 2021, 11:54 AM

it will surprise how well it pays

Jul 18, 2021, 11:55 AM

then gonna make one, might make some gimmicks like NFT representing a locked position

Jul 18, 2021, 11:56 AM

yes, change the game

Jul 18, 2021, 11:56 AM

and make it cheaper than dx sale like 0.03 ETH

then slowly make it higher :P

Jul 18, 2021, 11:56 AM

no wonder we see Elon as a genius

lol

Jul 18, 2021, 11:57 AM

have a few?

when it was $20

20 would be enough to not have to do anything anymore :P

Jul 18, 2021, 11:58 AM

lol still better than the pizza guy

Jul 18, 2021, 11:59 AM

well even if I can off ramp I prefer money digital and in crypto anyways :P

Jul 18, 2021, 11:59 AM

Zak do u know java spring cloud or anyone

Jul 18, 2021, 12:00 PM

I do kotlin

and vertx

Jul 18, 2021, 12:00 PM

Also, this would sell for a good amount of money. Even if you didn’t build a token locker. I’d even buy it from you if it simplified the process vs mine. Or if you’re feeling egalitarian, post it for free so people like myself can sell it lmao

I know someone that sold 100 line rug contracts for good money even though those are available on tokensniffer

Humans are truly lazy and just want to spend money man.

Jul 18, 2021, 12:03 PM

Now i want to create one that works like uniswap v3 lol, make nfts that represent locked tokens :P

and the solidity extension

and a nice theme :P

Jul 18, 2021, 12:10 PM

ohh lucky i run chromebook, can run linux beta

Jul 18, 2021, 12:11 PM

only contract will be rekt

Jul 18, 2021, 12:11 PM

i create token locker as well, well i just copy and pasted open source code,.. now i dont have to buy their "lockers" lmao

tho its a bit of work, i need to approve and spend manually from pancakerouter

to make it work.. i think its possible to add function though!

Jul 18, 2021, 12:12 PM

CMS jeets use Selenium scripts to upvote reddit posts and charge .6-1 BNB for it

Also freely available information.

Jul 18, 2021, 12:13 PM

this is exaclty what i want to do tbh.. its going to replace my day job

Jul 18, 2021, 12:14 PM

Rent in Nigeria is $8/month. If a single person buys a CMS post from them, they can feed their family and pay rent for a year.

Jul 18, 2021, 12:14 PM

aside from making tokens tho

i mean in my country, for IT engineers the pay is 20-30$ a day

its slavery

Jul 18, 2021, 12:15 PM

Which country?

Jul 18, 2021, 12:15 PM

for 9-12 hrs too

because fk india

overworking so we had to compete

Jul 18, 2021, 12:16 PM

I was looking for Solidity developers in PH but without success

Jul 18, 2021, 12:16 PM

well i was planning to leave anyways when i learn this selenium voting stuff and token creation profit

Jul 18, 2021, 12:16 PM

Yeah, learning how to bot reddit posts with Selenium can make you thousands of $$ per week. I followed a wallet that made $100,000 in a month with tokens although they did some highly unethical shit (one rug per day). Making money in this space is incredibly easy if you’re willing to put in the time and effort. Most people aren’t. If you can deploy a contract, you’re 95% ahead of everyone else.

Jul 18, 2021, 12:18 PM

i can deploy already hahaha but my problem is making it succesful

well i got a network of shillers

but the max i raised was for like only $200k mc

Jul 18, 2021, 12:19 PM

It's easy with node and puppeteer

Jul 18, 2021, 12:19 PM

Better work to make a good product and then you can make stable income

Jul 18, 2021, 12:19 PM

well i learn abit of marketing now too because of this its quite a good experience so far

Jul 18, 2021, 12:20 PM

very true

Jul 18, 2021, 12:20 PM

You can check Kardiachain ... and will see for what am talking

Jul 18, 2021, 12:21 PM

for crypto projects though, you also need to do web3 front-end part to make it a product

smart-contracts can only go far

so combination of web3 js , solidity, css = product

Jul 18, 2021, 12:21 PM

Cheaper than Bsc and have huge potential ... deployn projects on it without the need of huge investment

Jul 18, 2021, 12:22 PM

i saw becoswp promoted there last

Jul 18, 2021, 12:22 PM

That's a good project actually i like it

They already update the front end now is looking better

Good team working hard

Jul 18, 2021, 12:23 PM

most people get paid twice that per hour lol

nvm

Jul 18, 2021, 12:25 PM

philippines bro, its the reality

so like employers get the bigger piece of the cake and employees get the clean plate lmao

Jul 18, 2021, 12:25 PM

better to freelance

Jul 18, 2021, 12:27 PM

In other channel eth jobs ..is full with scammers

Jul 18, 2021, 12:27 PM

link pls

Jul 18, 2021, 12:27 PM

the dev discord doesn't have scammers

Jul 18, 2021, 12:28 PM

Ethereum Jobs

Jul 18, 2021, 12:28 PM

yeah fr

Jul 18, 2021, 12:28 PM

There is good Devs also but like 20%

Jul 18, 2021, 12:46 PM

hmm ya most of them probably work for startups/ only few freelance

Jul 18, 2021, 12:51 PM

Why didn't you tell the admins about them?

Jul 18, 2021, 12:55 PM

https://www.youtube.com/watch?v=hPJRFyl5SrM - haha and people buy those pdf smart!!

Jul 18, 2021, 12:55 PM

They ban the scammers but ...scammers change names use different accounts ...

So be careful ...no upfront payments only with milestone

Jul 18, 2021, 12:56 PM

the pancake router in testnet is different

what wallet address are u testing is it different from owner

there is code for exclusion

because the owner / contract creator is excluded from dividends

use testnet pancakerouter but it doestn work now

the GUI pancakerouter if you know hwo to use write contract

its hard to explain but you need other wallet to do the testing

you need to use router contract to add liquidity, do transfers and all bunch of stuff

if you understand this, then you should be good

i remember before i got honeypot from my own contract lmao

there can be shortcut which i am not familiar of though, thats just my opinion hopefully others can help you

https://pancake.kiemtienonline360.com/#/swap

i was using this GUI pancakeswap for testnet before, but for some reason its not working anymore

unable to add LP

or you can just remove these codes

i think you need to understand your code and remove the area where it excludes owner address to reeceive dividend

from there you can test it fully

i have not tried deploying this kind of contract sorry cant be of much help
