When you check for Polygon on the network list of your MetaMask wallet, you won’t find it there. When trying to set up Polygon on your MetaMask, you will find this article informative and very helpful. It’s no news that Polygon has gained much significance in the crypto industry. Polygon was formerly known as the Matic network before becoming famous for its lower fees, rapid processing, and spectacular scalability.

Since Polygon isn’t on the “network list” of your MetaMask wallet, you must personally add it to your MetaMask wallet. Setting up Polygon on MetaMask is a relatively easy task. This tutorial lets you learn the complete procedure quickly because it is explained in a way that anyone can effortlessly comprehend.

What is the Polygon Network? [MATIC]

Polygon is a platform focused on creating blockchain systems and networks compatible with Ethereum. Polygon is also called a layer 2 blockchain whose primary purpose is to assist Ethereum by adding to its scalability. These Layer 2 blockchains are tasked with working on pre-existing chains, thereby providing different kinds of advantages. One of the many advantages of the Matic network, or Polygon, is that it is a good alternative to the Ethereum network.

Ethereum is only able to process 14 transactions per second, and each transaction price ranges between $25 and $1000. This is because of the highly congested network. This issue is a prevalent challenge most users face when trying to transfer tokens or use Ethereum smart contracts on the Ethereum network. In some instances, the gas fees may increase rapidly and cost a lot of money, up to thousands of dollars.

Compared to Ethereum, a much slower and more expensive option, Polygon should be your preferred choice if you seek a swift, less expensive, and much better experience. Polygon is way faster than Ethereum because it can process about 65,000 transactions every second. This proves that Polygon is a much better alternative to Ethereum.

In processing transaction batches, Polygon (Matic Network) always uses its proprietary proof-of-stake (POS). By doing so, it results in a reduction in the total cost of a transaction. A typical case is where you pay a tiny bit of the fee that is to be paid every time you make a single transaction through Ethereum. Having gone through a quick overview of what Polygon is, we can now learn the steps for adding this Matic network to your existing MetaMask wallet.

New RPC URL: https://polygon-rpc.com or https://rpc-mainnet.maticvigil.com/

Chain ID: 137

Currency symbol: Matic

Block URL: https://polygonscan.com

Each field listed above has been further explained. Do well to read to understand the relevance of each piece of data.

Network Name: This field represents the network’s name, and in this instance, it represents Polygon. Input “polygon” into the field created to add it to your MetaMask.

RPC URL: in this field, a polygon node URL is required. Simply put, this is the address you will use whenever you want to transact using your MetaMask wallet.

Chain ID: in this field, you must type in a chain ID. The current chain ID of Polygon is “137.”

Currency symbol: The symbol of a cryptocurrency that is available on a particular network. The symbol for Polygon is MATIC.
