# What is a "Hidden bridge"?

Hidden Bridge is a special feature that has been developed for Venom Bridges on order to enable Venom users to transfer their tokens between EVM compatible blockchains in seamless and cost-efficient manner. When the cross-network bridging is happening, it happens via the Venom network, however it all happens in a seamless manner from the point of view of the user, as if the transfer were happening directly. If the user in question had to do the serious of transactions manually, the user would have to go over a series of transactions and cover the gas fee every time. But with the usage of Hidden Bridge technology the gas fee should be covered only once to complete all the bridging transactions necessary to achieve the ultimate goal.  

Also, what may be called a feature inside a feature of the Hidden Bridge is that the gas fee can be paid on an EVM compatible network which can be chosen by the user who undergoes the bridging transaction via the Hidden Bridge. So if, for example, the bridging is happening from BSC - via Venom network – to Fantom network, the user can choose, in native tokens of which network the fee will be paid. And as an additional advantage, it means that the user does not have to hold $VENOM in their wallet to complete the bridging transaction. The smart contract will execute all the bridging transactions and then will calculate and deduct the fee on the chosen network.
