Minting and burning fees

Current fee settings

Token	Minting fee	Burning fee
USD1	0%	0%
USD91	0.5%	0.5%
USD971	0.1%	0.25%
USD84	0.5%	0.5%

Notes

1. The above fees do not include gas fee.

2. Currently these fee settings are fixed and will be reviewed periodically to see if any update is needed.

3. USD971 minting and burning fee are different because the conversion frictions between AED and USD in practice are quite different. To be more specific, converting USD to AED is almost frictionless, but converting AED back to USD the fees or the margins are not that ignorable. So, setting both of them at 0.25% would be too high for minting USD971 while setting both of them at 0.1% would make burning of USD971 too cheap to generate some fair fee revenues for the protocol.
