Activity page shows all activities of everyone not just my own activity.

Thanks for all your points Midoelmelegy !

Thank you for taking time to read my comments.

I think it is better i keep all comments here. Found a new bug.

Anyone can see and edit unpublished items on any collection if they visit /collection/view/collection# try it. This should not be the case because i can delete or edit someone else collection prior to them publishing the item.

Also i was able to purchase the unpublished item owned by wallet (2) but now it is not showing up in the activity or the wallet. the transaction confirmed on etherscan.

The collection link: https://linkwellsystems.com:3005/collection/view/6200b56699c7ac3a85c4580c

The unpublished item link: https://linkwellsystems.com:3005/item/view/6204742d99c7ac3a85c45865

Transaction: https://rinkeby.etherscan.io/tx/0x436ae9854ac5494b3dfd7cf55cbcf97ff5e9ba9beeff0cf7e8ebef2c83827dca

Note: Unpublished items do not show up if i’m using the marketplace link then filter by collection, they only show if i use the collection/edit/collection# link.

Any plans to support existing nft cintracts like punks or Bayc?

Might be later not at the moment Midoelmelegy!

ok, but it is very important to be able to import existing nft to your marketplace.. even if this a separate customization with charges at least give options for that possibility.

It depends on the platform the script is written !

Testing before buying, managed to add collection and item, logged in another wallet and i managed to buy the item; however now no button to sell the nft i just purchased!?

The sell item option is not possible because of this bug below:

I logout from the wallet (2) that bought the item. I use wallet (1) which i used to create the item and collection in the first place.

I can see the item is automatically listed under wallet (2) for sale at the same price wallet (2) bought from wallet (1) which is 1 ETH. This means the nft is forever only going to be sold as the original price the creator sold it for initially unless someone makes a bid for a different price and the price is accepted by the seller i assume only then the price will change.

Please fix this as there is no way this works!!! Auto listing items for same amount means the users have no way to stop people from buying the nft from them at the same price they bought it at because it become immediately available for sale for the same price. The users also have no way to list the item higher than what they buy it for because its automatically listed for same price and they can’t change price or cancel the listing.

Update on my trials to increase the price through an offer:

I made an offer of 2ETH from wallet(1) to currently automaticaly listed item on wallet (2). I then logged out and logged in as wallet (2) and accepted the offer. i reloged in wallet one and see a buy button next to the offer i made earlier. I click buy button next to my offer and the transaction pops up ok and confirms.

Conclusion is correct item price now is 2 ETH and is also automatically listed for 2 ETH due to the bug i reported above.

Other bugs discovered is what i see on etherscan and dashboard are two different info:

https://rinkeby.etherscan.io/tx/0x9177d2872f13bb4cb21ff806473872db5f54b39cbe31339f6ee938fdd032460e Contract 0xc09e5d75d6bdc948286c26d4d0ee428bd613e2ee TRANSFER 1.44 Ether From 0xc09e5d75d6bdc948286c26d4d0ee428bd613e2ee To 0×2db821549ee6c572a318c2cfe80f06717cd30937 TRANSFER 0.5 Ether From 0xc09e5d75d6bdc948286c26d4d0ee428bd613e2ee To 0×8dfeee4d40cd2e9ad310cbd2fd2b544aa90191f7 TRANSFER 0.06 Ether From 0xc09e5d75d6bdc948286c26d4d0ee428bd613e2ee To 0xaceef0453de61b48cf0159749f192f5fc6a77298

what i see on dashboard is:

transfer: 2 ETH From: de ep To: Invest or Transaction Hash: 0×22897fc427f60bc0d28cffb9d788f5ec1f0fa3cdabb4cfdb07f1469db7e571ce Date: February 9, 2022 Admin_commission: 0.03 ETH

1. There is wrong data showing on frontend and backend. Admin commission should be 0.06 not 0.03. 2. I recommend removing the admin commission line from the activity because users already see how much was deducted in the transaction on etherscan and there is no need for user to see each admin commission on each sale.. too much information makes the table looks too long just to track one transaction. You should include admin commission % amount and royalty amount on the pop up when you click buy so the user can expect to see that reflected in the transaction details not the history.

For admin yes please keep the commission in the table as this data is only useful for admin use only just make sure to fix the bugs with the wrong data being shown that i mentioned above.

3. Also there is a typo. Commission is with double mm not single m.

Will check and update you ASAP!

how do you install this online? Do you have to use Vercel or Netlify? Or do you only use a fresh install of Ubuntu on a VPS? If that’s the case, How do you forward the “localhost:port#” for backend, frontend and adminpanel to an actual domain name or sub domains?

Hello Affendi ,Let me check and update you ASAP

As checked this is domain name settings when we buy domain name at that time we will set IPaddress in domain name settings, and we have used pm2 for backend and admin panel and for front end we used nginx settings…
