Independent project
Sidoor is not Circle, Arc, Arc.io, or an official bridge. We link to official resources so users can verify the underlying systems, but this site is operated independently at sidoor.trade.
Bridge flow
The bridge uses Circle CCTP through Circle Bridge Kit. Users connect a browser wallet, approve USDC, and burn USDC on the selected source chain. The recipient for the Arc mint is the same wallet address the user connected. Sidoor does not ask for passwords, recovery phrases, or imported seed phrases.
Fees and timing
Sidoor charges a 1% service fee on bridge transactions, shown before confirmation. Arc availability is controlled by the underlying network and Circle route status. If the route is not open, bridged USDC can remain pending at Circle until the route opens.
