Umbria Narni Bridge x Aavegotchi: First Look

The Umbria Narni bridge now supports the cross-chain migration of Aavegotchi token (GHST) between the Ethereum and Polygon networks.

Now there is a cheaper and faster way to transfer GHST tokens from Ethereum to Polygon and back again. Introducing the Umbria Narni Bridge, a cross-chain bridging solution which offers a superior user experience.

What is the Narni Bridge?

Tests conducted by the Umbria team have shown great improvement in bridging time and speed:

Bridging GHST using Polygon Official Bridge

Cost: $110 — $140

Speed: 48 Minutes

Bridging GHST using Umbria Narni Bridge

Cost: $50

Speed: 4 Minutes

Sounds great, but how does it work?

Bridging GHST tokens using the Narni Bridge

By default, the bridge assumes the user wishes to bridge between Ethereum and Polygon. If your Metamask wallet is connected to another chain the page will offer you a way to quickly and easily switch over to the Ethereum chain.

Otherwise, you can change the Send From → and → Receive On network selectors to the networks you are bridging between.

Use the asset selector to choose which asset to bridge and specify the amount you wish to bridge.

There are two ways to initiate the bridging transaction:

  1. You can bridge the funds using the Narni front-end using Metamask
  2. You can request a QR code to which you can send funds using the wallet of your choice.

We want to provide the option, but recommend that you use Metamask so you can track the progress of your transaction.

After the above steps, a final window will appear to confirm the transaction. You can choose the speed at which the transaction is processed using the fee slider.

When you are ready to finalize the transaction click SEND.

Then click Confirm in the Metamask popup window. You will immediately see the View Transaction button popup. You can click this button to see when your assets have reached the bridge.

After a few moments a pink check will appear. This signifies that the bridge has received the assets. A new section will appear below showing the progress of the bridge in sending the assets to the destination chain.

Another tick will then appear signifying that the bridge has sent the assets to your wallet on the destination chain.

You can click the View Transaction on Explorer button to see the blockchain record of this transaction. If you wish to configure your Metamask wallet to connect to the destination chain, click the ‘Connect to ________’ button at the bottom of the window.

Once you have clicked the connect button, you will see a new button appear. This button will trigger Metamask and show the asset in your wallet on the destination chain.

A Metamask popup will display to confirm whether it should track the asset. Click Add Token.

The asset will now appear in your Metamask.

Congratulations, you have successfully bridged GHST using Narni!

How to provide GHST liquidity to earn APY

To provide GHST liquidity, first go to: https://bridge.umbria.network/pool. You will see a list of available assets.

Use the Select Network selector to choose the correct network from the dropdown according to which chain you’re holding your assets on.

Select the asset you wish to pool by clicking on it in the window.

If you are not already tracking GHST in your Metamask wallet, you can click the Add to Metamask button. To add liquidity to the pool (pooling), click the Add Liquidity button.

Specify the amount of liquidity in the input box. You can select MAX if you wish to pool all of the GHST in your wallet (older versions of Metamask will break if you use too many decimal places, so stick to four decimal places).

Press the Confirm button in Metamask to finalize the transaction. After a few moments you will see your STAKE balance increase to reflect the liquidity provision.

Congratulations you are now earning additional GHST! 🎉

To unstake your liquidity click the Unstake button and sign the transaction on Metamask.

To see your GHST rewards for staking, click the history button

A window will pop up which shows all the rewards you’ve received for pooling GHST.

Now you can bridge GHST infinitely cheaper and faster AND earn APY on your tokens. WIN WIN.
