How Does Across Work?

Across is a [bridging function](http://across.to/) and provides incentives to relayers to offer short-term loans to users on L1. These loans are repaid to the relayer within two hours, from liquidity pools on L1. The pool is refreshed once funds from the canonical L2 transfer settle. Transactions are insured using UMA’s [Optimistic Oracle](https://umaproject.org/optimistic-oracle.html) (OO), which acts as a dispute resolution layer.
