Cheapest, fastest bridging between Ethereum and Polygon, Binance Chain, Fantom, Arbitrum, Optimism and Avalanche

The Umbria Network bridge (Narni) is a capital-efficient, multi-chain asset bridge, which provides the fastest and cheapest bridging solution for a number of EVM-compatible chains including Polygon, Binance Chain, Avalanche, Arbitrum, Optimism and Fantom. This enables anyone to explore Web3, crypto, games and NFTs to the max across a galaxy of networks.

New opportunities

Bridging between numerous blockchains provides more flexibility for users allowing them to take advantage of the unique features of different networks. Umbria’s Narni Bridge facilitates a new set of opportunities for DeFi, NFT and GameFi users who require faster and/or lower-cost bridging.

Anyone who’s ever played a blockchain-based game on an Ethereum network alternative will no doubt have experienced the pain of slow bridging (newbies often aren’t aware that you need to bridge — aka transfer ETH to another blockchain). Many platforms don’t integrate a bridge — so players have to leave the game site — or recommend a native bridge that is very slow and expensive. It’s very disruptive to gameplay and negatively impacts the gaming experience. Then there’s opportunities lost. For example, many Zed Runners will tell you how they’ve lost out on purchasing the horse they just had to have on Opensea or Hawku as they didn’t bridge their ETH to WETH quickly enough and someone got their first (read here). Umbria’s bridge negates these issues.

The Narni bridge opens the door to games on a multitude of networks. Want to race chickens on Chicken Derby on Polygon? No problem. Interested in exploring an idle browser game on Avalanche? Want to Play2Earn on Fantom? We’ve got you covered.

Arbitrage opportunities

Umbria’s Narni bridge empowers crypto traders to easily take advantage of arbitrage opportunities by enabling them to quickly and cheaply move assets between networks.

Prices of crypto assets can vary from chain to chain. A trader using Umbria Network’s Narni bridge could purchase the asset on a blockchain where it’s cheaper, transfer it to a blockchain where it’s more expensive and then sell it at the higher price and make a profit from the price discrepancy between the two blockchains.

NFTs on alternative networks

Many projects are now electing to deploy their NFTs on alternative blockchains due to the advantages in transaction-cost and speed on these networks as compared to Ethereum. These improved efficiencies bring new opportunities. As well as providing cheaper mints for their communities, NFT projects launching on other networks can expand the utility of their NFTs beyond collectable art into other areas like games. However, if bridging costs are high this erodes the benefits of deploying on a cheaper network.

Seen an NFT on Arbitrum, Polygon or Avalanche, but only have ETH on Ethereum Mainnet? No worries, we’ve got you covered.
