Umbria Narni Bridge
Bridge Developer: Umbria Team
Brief description of the bridge
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.

What is Binance Smart Chain?
BSC is a dual-chain architecture that will empower users to build their decentralized apps and digital assets on one blockchain and take advantage of the fast trading to exchange on the other.https://www.binance.com/
What is Polygon?
Polygon is actually a layer-2 scaling solution whose main objective is to convey mass adaptation to the Ethereum platform. Polygon brings Layer-2 scalability to Ethereum with its multi-chain ecosystem. It drastically improves the overall efficiency and workings of the Matic network. The main aim is to create more and more solutions to scalability.https://polygon.technology/
What is Arbitrum?
Arbitrum is a type of technology known as an optimistic rollup. It allows Ethereum smart contracts to scale by passing messages between smart contracts on the Ethereum main chain and those on the Arbitrum second layer chain. Much of the transaction processing is completed on the second layer and the results of this are recorded on the main chain drastically improving speed and efficiency.https://arbitrum.io/
What is Avalanche?
Avalanche is the fastest smart contracts platform in the blockchain industry, as measured by time-to-finality, and has the most validators securing its activity of any proof-of-stake protocol. Also is an open-source platform for launching decentralized applications and enterprise blockchain deployments in one interoperable, highly scalable ecosystem. Avalanche is the first decentralized smart contracts platform built for the scale of global finance, with near-instant transaction finality. Ethereum developers can quickly build on Avalanche as Solidity works out-of-the-box.https://www.avax.network/
What is Optimism?
Optimistic Ethereum is an EVM compatible Optimistic Rollup chain. It's designed to be fast, simple, and secure. The Optimistic Ethereum network lets you send transactions, similar to Ethereum, but with two important advantages: *Near-instant transaction finality. You know almost immediately if your transaction took place or not. *Much lower transaction fees. Typically between a 1% and 10% of of the cost on L1. *Decentralization. All transactions are posted to L1 Ethereum, inheriting the strong security guarantees of Ethereumhttps://www.optimism.io/
What is Ethereum?
Ethereum is both a blockchain network, an application platform, and a full-fledged programming language. The goal of the project is to create and publish distributed applications that do not require third party trust.https://ethereum.org/en/

I wish I had found this bridge/project sooner. I wasted so much money and stressed out on other bridges. Now that I have found it though the sky's the limit. Umbria is the way to go!!!
It works faster than any other bridge I used so far. There are also more networks covered, than listed here. E.g. BSC, Fantom, Arbitrum, Avalance!
Fast, easy, cheap. With a live support. Would recommend!
Amazingly inexpensive and efficient bridge. Great APY on staking with no impermanent loss.
Fast, cheap and really good and fast support. Would recommend!
! Dev AaronG <--- guy was amazing :) very cheap and easily explained how to complete weth on polygon transfer to eth on Ethereum network

Umbria is the fastest and cheapest way to bridge ETH to Polygon. Our whole community has used it. Only had an issue with someone using Metamask but the discord support helped sort the issue immediately and all was good!
Easily the cheapest bridge to get on and off Ethereum mainnet from Polygon, BSC, Avalanche and more to come. Highly recommend.
Umbria's user interface is super friendly. More than that however, I would like to review Aaron G. With in moments of posting a question on discord he was immediately assisting me and resolving my issue. Very Very impressed with his customer service and problem solving abilities.
Cheapest way to bridge ETH from Mainnet to Polygon!
wonderful , cheap, fast, easy to use BRIDGE ever.
Cheapest bridge. Devs are responsive in the discord and help with any problems. More wallet options are coming but you can still use the bridge with non metamask wallets by sending directly to the bridge address
The best bridge, with the cheapest rates. Their APY on Eth is amazing as well. I recommend Umbria to all of my NFT buyers when bridging funds over to Polygon.
Best (in a sense of fast, and lowest fees) bridge between Polygon and Ethereum. No impermanent loss liquidity pools are also a great opportunity to generate yield. I made only positive experience with Umbria Narni Bridge!
Fast and easy to use. Helpful developer team who's quick to respond and help on their discord.
Fast and Inexpensive, but most importantly the discord was super helpful.

Cheapest and fastest way to bridge Ethereum and Polygon. Support is also very quick to respond. Highly recommended!
fast bridge, low fees and easy to use. Aswell as very helpful team!

Excellent fast bridge, great value. Secure. Great team.
Fantastic bridge. Great value and fast. Staking rewards are very good. Team is active and responds quickly on discord. A+
Used it a couple time, it was fast and cheap.
I was looking for a bridge and LP and found both with Narni. Took half off because of occasional hiccups. But the team is phenomenal and turns issues around very quickly. Patient, responsive and knowledgeable. I feel like I am in good hands with this team!
This is a fantastic service and I've never had a problem so far. I use it to convert Eth to Weth and its the cheapest and most reliable I've found. Also part of the discord and very transparent and a tight community. Keep up the great work!
By far the cheapest and fastest bridging solution between Ethereum and sidechains / L2s. The pooling rewards are insane as well.
Fast and inexpensive. Great response time from discord and direct access to Devs. Best chain to use in my opinion and more to come from their team!

Fastest, cheapest bridge from ETH to and from MATIC. I have used it many times in the past few months. Never had a problem, unlike the official MATIC bridge, which is slow and much more expensive. Great Discord too - there is help available if you ever do have a problem, and the devs are very friendly.
Super service. Cheap, fast and reliable with excellent backup team.
Really great service and easy to use. I did have an issue where my funds were delayed but i contacted the team and for resolved pretty quickly! Overall totally recommend to use them.
Found bridging from ETH Mainnet to Polygon network expensive until I found Umbriaâ€™s Narni bridge. Lots of support too in case any problems or user inexperience occur.
Works fine, I had a problem with ETH blockchain where my tx got Dropped & Replaced but I contacted Umbria team through discord and they solved the issue so fast
Super fast, works well and REALLY REALLY cheap
Significantly cheaper and faster than other solutions â€“ with a highly accessible and responsive team. By far the best cross-chain bridge around!
Fast, cheap and smoothâ€¦ A lot like myself. Tech support always available. Quality across the board.
This is the Cheapest and Fastest bridge between Polygon <-> Ethereum, BSC <-> Ethereum, Avalanche <-> Ethereum. I would know - I created it. We are currently rolling our Fantom, Solana, Cardano, and many more this year. If you ever use this bridge and need any support from the team, we are always available in the discord channel.
Definitely the best Polygon - Etherium Mainnet Bridge. Fast, cheap (really cheap compared to other bridges) and still projects (BSC f.e.) in the pipe. Long story short: my Bridge #1 for Polygon
bridging fees are super cheap and quite fast. if there is ever an issue they have a team to take care of it. I can't recommend them enough. it's a no brainer to use a bridge that has tech support.
Fast, easy, cheap. Very recommended
Fastest & cheapest bridge I know for transferring between ETH and Polygon.
Paul CollomVerified user
Amazing bridge, for Ethereum, Polygon and now Binance Smart Chain. Fast, Easy and way way cheaper than any other Bridge I have used.
Well, it works only with Ethereum and Polygon networks. Strange decision from developers to create bridge interface as a widget. It's very uncomfortable in use. But it works fine. All transactions was made successfully.
To start working with this bridge you should have installed wallet extension, such as MetaMask.
You can learn more about how to get started in this documents section.
1. You need to have wallet extensions installed for each network you plan to interact with. On this bridge available wallet is only MetaMask.
2. You need to have some amount in the native network token to pay the network fees.
3. Connect wallet to the bridge site.
4. Make sure this bridge supports the token you want to transfer and only then you should start the transfering process.
