I am trying to deploy this contract
https://github.com/juustesout/EtherRanger/blob/main/EtherRanger.sol
to BSC Testnet, and I get this error in return :
"revert
The transaction has been reverted to the initial state.
Note: The called function should be payable if you send value and the value you send should be less than your current balance.
Debug the transaction to get more information. "
this is an example of a failed transaction on BSC Testnet

I tried forking multiple contracts from BSC, working tokens, but I always get the same error. I tried adding 'payable' to the constructor function, as other StackOverflow posts suggest, but no go. I have been reading any number of posts through Google Search, but I am getting nowhere.
The contracts compile flawless, no errors, no warnings, but they just won't deploy.
Could someone check if they can deploy this contract on BSC Testnet ? It may be a setting on my Remix or something, I am at a loss, I cannot tell where the error comes from.
I don’t know anything about this contract but I guess the hardcoded addresses for the IBEP20 and others are the problem. You need to deploy these contracts too and then pass their addresses to the interface addresses in your constructor.
But to connect to the BSC test network, you need to find the drop-down menu with a list of networks at the top of the MetaMask

when I try to run the pickWinner function of my lottery contract, I get such an error. With getPlayers, I can add players and query with players. The address of the manager is visible, but I cannot run the pickWinner function by selecting the address of the manager. What could be the reason?
I did try different values but i did not find solution
You need to post the code so we can figure out the answer, but I can see your pickWinner function has a restricted modifier. If the modifier is preventing the transaction from executing, then the client (remix, metamask, etc) won't be able to estimate the gas.
Just as the title says, on opensea testnets mumbai and ropsten, it 'imports' the smart contract to create the collection, however on the polygon mainnet, the same contracts are working perfectly.
The NFTs even show in my wallet on the mainnet, the contract is verified on etherscan & I can mint.
Please check https://polygonscan.com/address/0xb6AF03FE32Ac3DffDd4F2661270DFEE00C15c3d9
Is there anything special I have to do for the mainnet opensea to accept my smart contract?
Thank you very much!!
I created a new smart contract and added
import "#openzeppelin/contracts-upgradeable/token/ERC721/IERC721Upgradeable.sol";
Now it seems to work, still, I fail to understand why on the testnet opensea, it worked without it...
Sometimes development makes no sense.
After I have deployed a contract, I'm able to interact with the setter functions, as well as with the getter functions. However, after a day goes by, when i try to interact with the same contract again, that is still open and loaded on my remix I get a "pending" message when I try to set and change some variables like a different address. When I try to call a get function also nothing happens. I don't know how to interact with my deployed contract again.
When I reload the contract using the contract address "at address", it properly loads the contract if I select the right smart contract (containing the getter and setter functions) from the dropdown menu in the "deploy and run" page. However, the same problem occurs, that is: when i try to set a variable the transaction is not mined (pending indefinetly), and the call functions also dont read the data.
In order for me to move forward with my project I need to be able to access and interact with the contract if I need to change a variable which currently doesn't work...
Anyone has an idea how to solve this (probably trivial) problem? Thanks!
I am studying how to make BEP-20 tokens. For this I copied the following contract in remix to be able to study it:
Contract in BscScan
If I copy the whole file and compile it in Remix, when I deploy it it doesn't show me any getters. No public view function appears. If I look at the contract displayed on the testnet, it doesn't have any supply of tokens either.
I separated the files and libraries for a better reading. And it is then, when I try to display it, that I get the following error:
VM error: revert. revert The transaction has been reverted to the initial state. Note: The called function should be payable if you send value and the value you send should be less than your current balance. Debug the transaction to get more information.
It gives me the feeling that this contract does not generate the tokens ... What am I wrong?
I managed to fix the problem. As I suspected, in order to deploy the contract I have to remove everything related to uniswap and cakeswap. This displays the contract correctly.
If you wanted to deploy the contract with the uniswap interfaces in injected web3, you would need the uniswap testnet.
I found a test address for cake here:
Binance Smart change tesnet
I finished the https://www.ethereum.org/crowdsale tutorial in Ethereum and intentionally left the crowdsale having failed its funding goal (sample code at the start of the page). I fired the "safeWithdrawal" function from within Ethereum-Wallet and it adds the transaction on to the blockchain. But at this point I do not know how to listen to the response. The ether I sent was not returned.
I would like the ether to be returned.
I would like to know how to listen to the event that should have fired. Or any feedback mechanism to know that the why / how the event fired.

Currently, the Ethereum-Wallet has no debugger built-in for smart contracts.
I suggest, you code up your example using the browser-solidity. It allows you not only to code and test the deployment but got most recently a debugger built in. Click the little bug.
The debugger used in browser solidity is remix which is both a javascript IDE but also a library which can be attached to your own javascript projects. It is possible that future releases of Ethereum-Wallet will also include remix, this would simplify your task pretty much.
But for now, the mentioned browser tool seems like perfectly suited for your needs.
