NFT 10K LIST

Posted by Mike Gover

Required skills

List a 10k NFTs collection on opensea without paying gas fee using a smart contract.
My intentions are:
• deploy a new smart contract on Ethereum ( not paying gas fee, just like uploading one by one from opensea (lazy mint)).
• then, see all my 10k nfts on opensea without minting.
• after that edit my contract and see the changes in opensea.
Why?
Because I need the possibility to change some description, price and image after seeing all images on opensea.
Is that possible?

You can break LP Locked on DXSale? I doubt if anyone can

Posted by Crypto bz

Required skills

I have a Liquidity Pool locked on DXSale with an end date in December 2024.
I made a token on the BSC network. I created an LP on Pancake and blocked the liquidity pool on DXSale until December 2024.
The project does't exist anymore. I need help to break the lock. But nobody managed to do that. I believe it is impossible.
P.S.1:
This LP has a balance of 12 BNB ($5500). Since I don't believe anyone can break this lock, I'm willing to sell it to you for $2,500. Since you can hack, it's a good opportunity right? 100% profit after hack
P.S. 2:
I won't pay you upfront to buy new tools. Or whatever the reason.
