# Native Bridge

## In the context of permissioned L1s?

## In the context of Rollups

**When needed:**

Trust-minimized cross-chain communication is possible across rollups with a common consensus and data availability (DA) layer, removing the need for third-party bridges for inter-rollup connectivity.

These rollups will maintain a native bridge with the DA layer, which will serve as a central hub linking all these chains together.

**When not needed:**

The rollups will be part of an ecosystem where there isn’t a need for each rollup to form individual  native bridges with each other in order to facilitate cross-rollup messaging or liquidity transactions.

**Drawback**

such a system is limited in functionality (number of tokens support, speed, chains connected) and there’s still a case to be made for messaging protocols for industry-wide connectivity,
