Here's the whole documentation about NFTs: https://docs.elrond.com/tokens/nft-tokens/

Replace /balance by /esdt

Good idea! I will try it now

AFAIK, the nonce must be increased after each transaction you made with your wallet ;)

Yep for sure! ;)

Ah maybe !

And the template will provide you an example https://github.com/ElrondNetwork/dapp-template of how to use dapp-core ;)

Hey! Here's your answer https://docs.elrond.com/developers/nft-tokens/#transfers-to-a-smart-contract ☺

const STR: &str = "this is a string" const BYTES: &[u8] = b"this is bytes" The STR use allocation, and thus increasing your gas fees. The BYTES is allocation free

https://docs.elrond.com/developers/best-practices/storage-mappers/ Use SingleValueMapper when: you need to read the whole array on every use the array is expected to be of small length Use VecMapper when: you only require reading a part of the array T's top-encoding is vastly more efficient than T's nested-encoding (for example: u64)

Here's a good introduction to develop a SC and link it to a web page: https://docs.elrond.com/developers/tutorials/your-first-dapp/

Thank you for your answer! I pass an egld balance (like 0.9) instead of a BigNumber in the transaction ahah

The more you are on-chain, the better is it, I think ? You can easily update attributes of an NFT: https://docs.elrond.com/developers/nft-tokens/#change-nft-attributes

Good question ! For the moment, I am working on setting the URI of the NFT to the server that generate the image. So the URI of my NFT would look like www.mywebsite.com/?eyes=blue&skin=purple ? I will try to host it on IPFS after ^^
