What is amount in case of mosaic transfer

Tech Support
#1

Hi,

What is the amount mentioned in the mosaic transfer? On nembex explorer, it’s showing it as to quantity and on nemtool is shows the amount as 0 even if it’s calculated from API response then it should be 1.

example,

{
“timeStamp”: 83163971,
"amount": 1000000,
“signature”: “05961cc8d0b55cc87a96f8c9dbcfda8b6188dc1f05c565e0c542d53992c35a03734986e67233d53caf6aa24978bcb55b45abe91a412a3c124ddf5c13e19e0f0d”,
“fee”: 100000,
“recipient”: “NDUJFAEVV6MUJNHMQBWINYQTFIKNTV7JQD7ZE4WR”,
“mosaics”: [
{
"quantity": 3,
“mosaicId”: {
“namespaceId”: “nemket.nemket2017”,
“name”: “entry”
}
},
{
"quantity": 1,
“mosaicId”: {
“namespaceId”: “nemket.nemket2017”,
“name”: “lottery”
}
}
],
“type”: 257,

“signer”: “83ea57df975db23a383bd1a89ecca9a5a5ba84d78a12248d678c539b5bd67279”
}

If mosaic array is not empty then amount is multiplier. If you want send exactly what in mosaic array amount should be 1000000, if you will set 0 then you send nothing 0 * quantities_in_mosaic_array.
If you will set 2000000 you will double quantities in mosaic array.

#3

It means from the above example amount is 1000000 then these 2 quantities of mosaics are transferred.

If the amount is 0, then 0 quantities of mosaics are transferred event if quantity with 1/2… exists in mosaics.

#4

How these mosaics quantity is calculated in XEM? User who created it can set it? or how?

Means 1 quantity of mosaic = How much XEMs/Amount?

#5

How these mosaics quantity is calculated in XEM? User who created it can set it? or how?
Means 1 quantity of mosaic = How much XEMs/Amount?

I’m not sure what you mean. Transaction sender is deciding how many mosaics want send

#6

Ok. Let me elaborate more on what I want.

I’ve only concern with how much amount/fees deducted from the sender’s account and how much added to the recipient’s account.

So, from the above response, my assumption is,

Deposit :
For 1st mosaic - 1000000 * 3 = 3000000
For 2nd mosaic - 1000000 * 1= 1000000
3000000+1000000 = 4000000
4000000 amount or 4000000/1000000 = 4 XEMs are deducted from signer’s account [83ea57df975db23a383bd1a89ecca9a5a5ba84d78a12248d678c539b5bd67279]

Credit :
4000000 amount or 4000000/1000000 = 4 XEMs are credited to recipient’s account [NDUJFAEVV6MUJNHMQBWINYQTFIKNTV7JQD7ZE4WR].

Fee deposited from signer’s account [ 83ea57df975db23a383bd1a89ecca9a5a5ba84d78a12248d678c539b5bd67279 ] =100000 or 1 XEM

Fee credited to harvester’s account [ ABCDEF…] = 100000 or 1 XEM

Please correct me if I’m wrong somewhere.

  • when mosaic array is not empty amount is multiplier
  • when mosaic array is empty amount is amount of XEM sent

In your example

Amount: 1000000

“mosaics ”: [
{
"quantity": 3,
“mosaicId”: {
“namespaceId”: “nemket.nemket2017”,
“name”: “entry”
}
},
{
"quantity": 1,
“mosaicId”: {
“namespaceId”: “nemket.nemket2017”,
“name”: “lottery”
}
}
],

So you sending exactly what is in mosaic array because amount = 1000000/1000000 = 1

So you sent:

  • 3 nemket.nemket2017:entry and
  • 1 nemket.nemket2017:lottery

Thank you so much. This is what I want!

And if the amount is 2000000, then 2000000/1000000 = 2
So from above,

  • 3*2 = 6 nemket.nemket2017:entry and
  • 1*2 = 2 nemket.nemket2017:lottery
#9

yes, that’s correct

#10

Thanks!
