Fees: For example, I created a token on the stellar network, called NRO. is it possible for me to define my own fee amount? That is, a specific fee for my token?

[unknown] For example, we are creating a project called neurobanco. it's a social project which aims to create a social currency called NEURO COIN (NRO) Our goal is to help Unbanked / vulnerable people. • Recyclable Material Pickers • Truck drivers • Motoboys • Family farming • Cleanliness and conservation staff • Craftsmen & seamstresses • Chemical dependents • Refugees • Craftsmen and seamstresses • Fishermen Fees: is it possible for me to set up a spare fee for the fee charged by the stellar network? for example, I would like to charge a slightly higher amount for the transaction fee on the NRO currency / token, this spare fee we will use to maintain the infrastructure of the app's servers. Among other functions aimed at improving the welfare of the less fortunate. And finally, if it is possible to charge a spare fee. Where do I how can I configure this rate values ?? can you refer me a document on the subject? If it is not possible to do this, can you help me with any alternative? Even if this fee is paid in xlm, can I charge a slightly higher fee and retain that extra amount for the maintenance of my project? Thank you all!

Friend, thanks for the feedback! Exactly what I need to do in my project, are you a developer? If so, how much would you charge to develop this api for me? or these smart contracts?

All fees on Stellar are paid in XLM. It's not possible to pay them in other tokens. But maybe it would be possible to have a setup where you pay the XLM fee + extra tokens. This would maybe require having another signer that "approves" all transactions with a particular token only if they include a fee.

Could you share more information about your use case? I can't think of a good reason why someone would like to have extra fees.

I assume what you want is to charge some amount when moving the NRO asset.
Something similar to Paxos Gold's on-chain transaction fees 1.
For example: A sends 100 NRO to B and instead of B receiving 100 NRO, they receive 99 NRO, making it a 1% transaction fee.

If that's the case, Stellar doesn't provide a mechanism to do that natively. But it can be emulated if all transactions regarding the asset need to go through your system.

The way Paxos achieves that is by implementing the behavior in the smart contract that manages their token.

What you can do in Stellar is basically disallow transactions of your asset in the wallets and provide a mechanism in your services/api forcing the users to go through to operate with the asset. See Control Access to an Asset – Stellar Documentation for some references.
If that's the case when a user asks you for a transfer from A to B of NROs, you would be able to craft a TX with the operations that are necessary to do the TX and charge the fee.
For example, if A tells you it wants to send 100 NRO to B then you would craft the following transaction:

Ops necessary to unblock operations of NRO
Payment from A to B of 99 NRO
Payment from A to you of 1 NRO
Ops necessary to block operations of NRO

The proper signatures then need to be applied and published.

GilbertoMattiello No problem. I am a developer, but I am currently too busy to take on some extra work. You might be able to find someone else that can do that here. I don't know if there's a place where you can post "Help needed" posts. Maybe a mod/admin knows and can comment on it
