Minting NFT via smart contract
Hi devs!
I need to mint a NFT only if the token name equals one input utxo id.
I need to do that to ensure the uniqueness of the NFT, otherwise other people could mint the same token from outside the smart contract.
On Cardano there is the concept of minting script, which is a smart contract that guards the minting/burning of tokens for a particular policy....
Check if a box is guarded by a script
Hi devs,
I need to check if a box is currently locked (guarded) in a smart contract.
I basically need to distinguish when a box comes from a wallet and when it comes from a smart contract.
Is there an easy way to do it in ErgoScript?...

Hi, is there any way I can accomplish this?
I managed to run a test node following the docs(https://docs.ergoplatform.com/dev/start/testnet/#securing-the-api)
And then I tried to un-comment
knownPeers to make it an empty array.
I was trying to find a configuration option where I can somehow change the network Id or something.

Explorer-backend and frontend help
Okay, I'm new to all this so please bear with me.. I'm setting up the explorer-backend in support of my project. The reason I believe I need it is to take snapshots for airdrops to NFT holders. Problem is now that I've got chain-grabber syncing I'm not sure where I go from here. Do I need to install the explorer-frontend as well? Would anyone be able to explain how to actually take a snapshot of the chain and how I can isolate the wallets that hold NFTs from a specific project?

[Help needed - Ergo node wallet] wallet balance discrepancy in Ergo node wallet display, and block e
Hello. I am using an ergo node wallet for my mining payouts. Recently, I have received two new payouts, 1 ERG each. However, this is not reflected in the node UI wallet (only shows ~1 erg, which is the original balance).

Upon checking the block explorer, the wallet balance is correct (~3 erg). Payout dates of the 2 ergs from the recent payout are 4th and 6th September, 2022....
