As the demand for various blockchains for different web3.o technologies grow, so does the need for these blockchains to interact appropriately.

Blockchain is a distributed ledger technology that employs cryptography to guarantee data and transaction reliability and integrity. Blockchain networks enable various services such as secure databases, immutable ledgers, decentralized applications, decentralized finance, nonfungible tokens, and cryptocurrencies.

Bitcoin, Ethereum, Avalanche, Polygon, Solana, and Arbitrium are a few blockchain networks and cryptocurrencies that leverage various blockchain technology.

Crypto bridges provide the needed interoperability for these blockchains to interact with each other. One of the most popular crypto bridges today is the Polygon Bridge.

Note: Before proceeding, you will need Metamask. You will need to set it up if you don't already have it.

How to Bridge your Crypto from ERC 20 to Polygon

It would help if you had a suitable cryptocurrency wallet, such as Metamask, to bridge tokens from Ethereum to Polygon. Follow the instructions in this guide to establish a Metamask wallet if you don't already have one. Additionally, you'll need to get the Metamask browser extension and install it.

You need a compatible wallet like Metamask to bridge tokens from Ethereum to Polygon. You will have to download and register on the Metamask wallet if you don’t have one. Then download the chrome browser extension for your Metamask.

  1. Login to the Polygon website wallet and click the “Polygon Bridge” option.
  2. Then connect your crypto wallet by clicking on the Metamask option (after successfully creating a Metamask wallet for yourself).
  3. You must sign a message to link your Metamask wallet to your Polygon wallet. It is free to sign. Click “Sign" to continue after ensuring you are on the right Polygon website by confirming the website address.
  4. You will be redirected to the polygon bridge to swap your cryptocurrency and start swapping your ERC20 token to the Polygon network.
  5. Then click on “Deposit.” Choose the ERC token you would like to bridge to Polygon. Select the amount of the token and click on “Transfer.”
  6. A warning note then pops up on your screen. It informs you about the “do’s and don’t” on the Polygon bridge.
  7. Click “Continue” to proceed with your transaction.
  8. Then you will see the gas needed to complete your transaction. This depends on the number of people using the network at this point. If there is congestion on the network, the gas fee might be slightly higher than the usual amount. Click “Continue.”
  9. The next tab is for you to double-check your transaction details (the amount and the gas fees) before finalizing the transaction. Click on “Continue.”
  10. Then you will see a prompt similar to the “sign signature” prompt you saw when connecting your wallet. Check the details and click “Confirm.”
  11. You can monitor your transaction live on Etherscan.

PS: When bridging your crypto from the Polygon bridge back to the Ethereum network, it usually takes less than 2 hours to get your cryptos to arrive in your wallet.

Although the Polygon bridge has its annoyances, it is one of the most accessible and versatile DApps to bridge your crypto from the Ethereum blockchain to Polygon.
