_Across Protocol differs from other bridges in the way that we’re able to perform near-instantaneous transfers. When you bridge assets from_ [_L2 to L1_](http://across.to/) _on optimistic rollups, you can expect a 7 day wait — not ideal, we know. When you use Across, you can expect to receive your funds in 1–2 minutes due to the speed of the relayers and our process of relayers giving funds to the user upfront, with the liquidity providers waiting through the challenge period and the relayers taking on 2 hours worth of liveness._

Across Protocol prides itself on speed. This may be apparent from our outward messaging, or perhaps you’ve done transfers on our [cross-chain bridge](http://across.to/) and have experienced it yourself. With this being said, it may still be unclear exactly _how_ we’re able to do this. This article aims to be your key to understanding exactly how we’re able to be _so fast._

Nice project and congratulations to the team for their efforts and dedication and highly appreciated the visionary thought of the project‬ ‪Thanks to the team again‬
