The total fee comprises the operation fee and a predefined factor (0.02).
Total=operation∗0.02
The operation fee is as follows:
Deposit operation = 2 unit
Withdraw operation = 1 unit
Transfer operation = input*1 unit + output*2 unit
Where input and output represent the number of zk assets.
During the testnet phase, the Scuba protocol collects Scuba token as transaction fee. In the upcoming Mainnet, any tokens (USDT, USDC) can serve as transaction fee.
