Iam happy that the issue has been fixed, you’ve right you have to be in Testnet as mentionned in the news bar and your balance should be at least 0.1 Algo(you don’t have to opt-in to USDC), that was a good point and I will include that in the help-text so thank you [@JDTamerlan](https://forum.algorand.co/u/jdtamerlan).

Hi [@JDTamerlan](https://forum.algorand.co/u/jdtamerlan) and thank for trying Algolancer,
Iam just checking that and it works normally, please check again your Algorand address, it should be exactly 58 characters without any white spaces, or you can import all your Pera Wallet addresses directly by “Get Pera Wallet Address” button.

Thank you [@SilentRhetoric](https://forum.algorand.co/u/silentrhetoric) for your help.

[@Xxiled](https://forum.algorand.co/u/xxiled) I will update boxes manually each time NFTs collection will be changed, there is no risk at all because all what the contract should do is checking NFT’s validity from the box.

[@Xxiled](https://forum.algorand.co/u/xxiled) interesting, why should I do that instead of feeding my contract with just boxes?

Thank you [@scholtz](https://forum.algorand.co/u/scholtz) for the recommendation.

Okay [@scholtz](https://forum.algorand.co/u/scholtz) I think I have understand the idea from Arc72, to be honnest I think that implementing NFTs within protocol layer as standard assets is much better, especially if trading them is an option, however the tickets example was so helpful.

Amazing [@scholtz](https://forum.algorand.co/u/scholtz), is that possible using Pyteal?

Aaaah okay, I think I understand it now, created_application_id is what I missed, thank you for your help.

Hi [@scholtz](https://forum.algorand.co/u/scholtz), what do you mean please ? if possible to explain with some details Iam not very expert with Algorand.

Thank you I think I understand you now, and I think that nodelay will be perfect for my use case.
Yes Iam using Sandbox with last up to date catchup because I have to interact with real-like Algorand blockchain: my dApp use Pera Wallet to sign transactions so Sandbox should have blocks where dispend transactions are being processed.

Can you explain please?

Thank you [@NFNomad](https://forum.algorand.co/u/nfnomad), it supports all types of transactions?

Thank you [@PatrickB](https://forum.algorand.co/u/patrickb) for sharing this link, it looks a good solution, however it is also in React(JS) so the dApp should have and build transactions in React which is not my case.

Very understood [@ROAM](https://forum.algorand.co/u/roam), thank you so much for your help, hoping for more great communications like this one in the future, I appreciate your help.

Thanks [@ROAM](https://forum.algorand.co/u/roam), it was a great pleasure to talk with you, Iam new to this community and it seems from the beginning that it is wonderful, there is last thing and please feel free to ignore it if you see that it was long discussion, I just don’t want to create a separate topic for it: I can see many dApps in the forum, I’m wandering what is the best way to start developing dApps on Algorand and including liquidity provision mechanisms.
