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.

Documentation
Stake $UMBR and Earn with no Impermanent Loss
Liquidity providers of $UMBR in the Narni bridge will earn their share of a 0.3% fee, whenever anyone transfers assets cross-chain. The rewards earned will be paid in the assets used to bridge between networks.

Anyone can stake the below assets and earn their share of a 0.2% liquidity provider fee, with absolutely no impermanent loss. However, staking UMBR will result in 0.3% fee rewards of all assets used on the bridge.
