hi, how to fix this?
Internal JSON-RPC error. { "code": 3, "message": "execution reverted: Crowdsale: weiAmount is 0", "data": "0x08c379a00000000000000000000000000000000000000000000000000000000000000020000000000000000000000000000000000000000000000000000000000000001943726f776473616c653a20776569416d6f756e74206973203000000000000000" }

OZ is even dropping this, since your code is in 0.8.4, you don't need SafeMath.

Hi i deploy Contract and start ICO . and send BNB to contract with gas 300.000
tx confirm but :

1. bnb dont send to wallet (deposited to contract)
2. token not porchesed

see this tx

hello, code is not working, always reverted, also there's wrong validations in the startICO function (softCap and minPurchase to be exact), it looks great but sadly it's broken, also SafeMath isn't required on Solidity 0.8+

The receive() function should check for contract supply too, because it just validate the date, not the available supply on contract.

Hi Freezy, I have cloned your code few times before and it worked fine. Today I am trying to use the old code and also this new one but every time the transaction gets failed.

Hello,

Thanks for contract we have issue everything works except bnb is not transferring to wallet address. Please help.

but I have this error
Internal JSON-RPC error. { "code": 3, "message": "execution reverted: Crowdsale: weiAmount is 0", "data":
even though I have filled in the rate as on your site

Hi.
Meta Mask showing this error when buying token and start ico:
ALERT: Transaction Error. Exception thrown in contract code.

Hey thanks for the presale contract,

I successful deployed it but when ever I send bnb to the contract address it fails and no error is emitted please can you explain what I did wrong

My token details
decimal:- 8
hardcap:- 500000000000000000000 (500 bnb)
softcap:- 50000000000000000000 (50 bnb)
minbuy:- 1000000000000000 (0.001 bnb)
Maxbuy:- 1000000000000000000 (1 bnb)
rate:- 100000000000 (1000 token = 1 bnb)

Thanks for your help @FreezyEx

Hey FreezyEx,

I'm trying to deploy your ICO script and keep getting the following - Error! Unable to generate Contract ByteCode and ABI .

I was wondering if you know what causing this. I've looked online but so far haven't found any fix for this. I'd really like to use this to launch my token.

Thanks

I just want to know why this _tokenDecimals = 18 - tokenDecimals; tokenDecimals is substracted from 18

How to interact with web3?

Hey Freezy. I very much appreciate the help so far. I've got the presale contract deployed but when i go to start the ICO i get the following transaction error - Fail with error 'availableTokens should be > 0 and <= totalSupply' .

I set the following settings on deploy for the rate (5 Trill per bnb) , address, token address, etc.
5000000000000,0x5B9cED86ecDc2d859D8126A08E429f07d9B15409,0xa43c607c836c250f851a50c385d4d906ea829c66

On startICO I set the following

0 | endDate | uint256 | 1624238552 - (Jun 20 2021 20:22:32)

1 | _minPurchase | uint256 | 100000000000000000 - (equal to .1 ETH.BNB)

Not sure why it's giving me the availableTokens error as supply is 1 quadtrill. I've looked this up and down and i see no reason that they contract is seeing my token with zero tokens available. I've read through the code and I know it's happening in the code below but i see no reason for the error.

uint _availableTokens = _token.balanceOf(address(this));
require(_availableTokens > 0 && _availableTokens <= _token.totalSupply(), 'availableTokens should be > 0 and <= totalSupply')

Thanks

Mike
