If I want to create an asset out of my song, how can I add metadata to this asset?

To complement @Maugli ’s answer: you can store small amounts of data on-chain but most blockchains (including Ethereum) are not made to store large amount of data. This is because storing data has a huge cost (cost of disk) and storing data on chain has even more cost as it’s replicated by all (arch…

Hi, @anoushka , welcome! You can specify an URL when you create your asset. Also, you can create a hash256 value from your song, and specifiy it when you create your asset. This “proves” on the blockchain that you had access to this song at the time of asset creation. After asset creation you can …

If I add my meta data to that URL, will it be on the blockchain?

No, definitely not. It will be on the http server the url points to. See also ARCs/arc-0003.md at main · algorandfoundation/ARCs · GitHub and ARCs/arc-0069.md at main · algorandfoundation/ARCs · GitHub

then how do I keep it on chain?

Volume data should be stored separately, not on the blockchain. Only a pointer to the volume data – in your case a pointer to your song – should be stored on the blockchain.

[image] fabrice: if you are using ARC-69, ARCs/arc-0069.md at main · algorandfoundation/ARCs · GitHub , the metadata would be on-chain directly as long as it’s small enough (less than 1kB). If you’re using ARC-3, the metadata is off-chain in IPFS/arweave. So if I’m using IPFS, my data won’t b…

Your data will be accessible by the IPFS filename, stored on the blockchain. Blockchain data is PUBLIC, so others can read this filename, too.

So if I’m using IPFS, my data won’t be accessible on the blockchain by other accounts?
