# Omchain Bridge

Omchain Bridge, developed by Omchain Foundation, is a cross-chain bridge that facilitates the transfer of assets and data across various blockchains. This bridge enhances user experience by increasing compatibility between different blockchain networks and expanding liquidity pools. It offers users the opportunity to benefit from the advantages of different blockchain networks. Technically, the Omchain Bridge enables the secure and efficient transfer of tokens and other digital assets from one blockchain to another, thus providing users with broader access and interaction in various ecosystems.

&#x20;You can access the[ <mark style="color:blue;">**Omchain Bridge**</mark>](https://app.omchain.io/bridge) through this link.

### How does Omchain Bridge work?

<figure><img src="/files/C7gyksrMu57NmN2fhMPv" alt=""><figcaption></figcaption></figure>

You can use the Omchain Bridge to transfer your OMCs and other supported tokens among supported networks.

Currently only the following networks are supported;

* **Omchain**&#x20;
* **Ethereum**
* **Binance Smart Chain**
* **Polygon**
* **Avalanche Network**

Select the sender network accordingly and destination network as **Omchain**. Later from the token section select **OMC** and connect your wallet.

The bridge will walk you through necessary steps shown below;

* ConnectWallet (either via Metamask Extension or a wallet that supports WalletConnect)
* Approve (this step is necessary for the Omchain Bridge contract to be able to bridge your assets)
* Enter the amount you would like to bridge
* Click on Send

Upon clicking on Send, your wallet will prompt a transaction request and upon your confirmation, the bridging process will start.

Once you are redirected to the transaction page, take note of the URL you are visiting, in case your transaction confirms later than expected so that you can close your browser and return when it's confirmed.

### Transaction URLs

The URL of each transaction is in the format of;

<mark style="color:green;">`https://app.omchain.io/status/source network ID/transaction hash`</mark>

For example; <https://app.omchain.io/status/21816/0xa9e3fce6db2cad66bb9667e6a53af84ece33851f9c933adfecb35fa8eb5ff52f> The **21816** in the source network ID part of the URL means that this bridge was started from the Omchain. And the **0xa9e...52f** part is the corresponding TX ID on the omchain. We can visit the transaction page on the Omchain any time we want, to see the status of the transaction.

### Confirming Transaction & Adding Network

Once your transaction is completed on the source network, you will also see on the transaction details page that the transaction is completed.

After that you can click on the **Add Network** button to change the network on your wallet to the destination network. If you don't have the RPC details for the Omchain, the **Add Network** button will prompt the network details and upon your confirmation, the network will be added & switched on your wallet.

Please make sure that you are using a wallet that supports the addition of custom EVM networks.

### Finalizing The Transaction

If you are bridging OMC to the Omchain, as soon as your deposit is seen, the corresponding amount of OMC will be sent to your wallet on the Omchain. You don't have to do anything else to receive your asset.

If you are sending different assets between the networks, you will have to click on the **"Receive"** button to interact with the deployed omLink contract in the corresponding network to finalize the transaction. After you click the Receive button, you will be prompted with a tx. Confirming that TX will deliver your ticket to the **Omchain Bridge** smart contract and your assets will be transferred to your wallet.

You can click on the **Add** button to add the token you are bridging to your wallet.
