Infinite Approval setting: infiniteApproval
When the user swaps tokens with the widget for the first time, they have to grant Squid permission to route the tokens on their behalf.
By enabling the Infinite Approval setting by default, you authorize Squid to route an unlimited amount of them. In some instances, unchecking the Infinite Approval option can improve the user’s security since it limits the amount that is approved by Squid's Router contract.
Instant execution setting: instantExec
Instant execution is a feature coming in early 2023 that makes any transaction up to only 10 seconds long. A small fee is associated with this setting.
