Why do I need to approve my WBNB to the HOTROUTER address?

Coinfair’s unique BMM mechanism enables us to confidently distribute trading fees to users via DRS. In order to accurately execute DRS, we require users to authorize WBNB for HOTROUTER in advance, rather than relying on pre-calculations(This approve is only utilized when a user converts ERC20 tokens to BNB).

Furthermore, when the remaining authorized amount falls below 66% of the estimated requirement, users will be prompted to grant additional approve to ensure subsequent processes run more smoothly.

Will this approve create any security risks?

All Coinfair's smart contracts are open-source and fully transparent, allowing anyone to audit them. We guarantee that any WBNB you authorize will function just like any other token approve—solely for SWAP operations—ensuring there is no risk of loss to your assets.
