The Umbria Narni Bridge uses a novel liquidity-provision protocol, to speed up, and lower the cost of cross-chain bridging.

The bridge facilitates cross-chain migration of assets by holding multiple assets on multiple chains, simultaneously, in liquidity pools. Unlike traditional cross-chain bridges, the Umbria Narni bridge is able to facilitate cross-chain transactions by receiving assets on one chain, and giving the respective asset on the destination chain.

The Umbria Narni bridge is different to other cross-chain bridges, because it does not rely on validator smart contracts, which can dramatically slow the bridging process. By removing the necessity for such validation, the Umbria Narni bridge can complete cross-chain transactions with an order of magnitude cheaper fees.
