UTXOs

Given that:

• ETH is a token user wants to send
• OMG is a fee token

ETH	OMG
5	5
10	10
15	-
20	-

Strategy

Pick fee tokens first for the stealth inputs (because fee token is often used)

Send Amount (ETH)	Fee Amount (OMG)	Inputs	Stealth Inputs
5	3	5 ETH, 10 OMG	5 OMG, 20 ETH
35	8	20 ETH, 15 ETH, 10 OMG	5 OMG
35	15	20 ETH, 15 ETH, 10 OMG, 5 OMG	-
12	15	20 ETH, 10 OMG, 5 OMG	15 ETH
30	10	20 ETH, 15 ETH, 10 OMG	5 OMG
15	10	15 ETH, 10 OMG	5 OMG, 20 ETH

We also need to clarify two things:

• Do we prioritise larger or smaller inputs for stealth merge? 🤔
• How do we prioritise currencies for stealth merge? I propose we order currencies by number of UTXOs, given that each currency has an exit queue and this is what we are trying to shorten in the case of a mass exit.
