Is it possible for an account in algorand to cover transaction fees for a transaction if that account it neither sender or receiver?

Question

recently I've been fiddling around Algorand.

I was going through the documentation & am wondering.

How is it possible for an Algorand Account to cover transaction fees for a transaction.

if it's neither sender or receiver?

Answer 1

This is really an Interesting question,

I was also thinking something similar.

I actually found Algorand do have a fee pooling mechanism.

Before you do it you'll need to understand how Atomic transactions work.

For this you can check out algorands documentation here

In simple words it ensures either a transaction is executed fully or it fails.

this allows to enable use cases like

• Circular Trading
• Group Payments
• Pooled Transaction fees
• Distributed payments

to execute and atomic transaction you'll need to group all the transactions & set transaction fees higher.

Like before you compose an object set transaction fees to something like 2000

txn.fee = 2000

and the transactions you want to make it free for would have to set transaction fees at 0.

txn.fee = 0

this will allow you to cover transaction fees for other accounts.

This is bit confusing but becomes much clear from this conversation on algorands forum
