Liquidity lending protocol reduces costs and speeds up bridging
Narni uses a novel liquidity lending protocol, which hosts liquidity pools of singular assets on different networks. As well as significantly speeding up and reducing the costs of transactions, it generates fee-based rewards for liquidity providers who add a single asset to the bridge.
Whenever a participant migrates assets between two cryptocurrency networks using Narni, the liquidity providers receive a share of a 0.2% fee in the native crypto/token they supplied. The APYs can be viewed here:
In addition to Arbitrum, Umbria currently provides the fastest and cheapest bridging from the Ethereum network to the Polygon network, Avalanche network, Binance Smart Chain and Fantom (and vice versa).
