How to sell coins on the Polygon chain? How to add Polygon network to MetaMask wallet

php editor Apple has carefully compiled an article on how to sell coins on the Polygon chain. By adding the Polygon network to the MetaMask wallet, users can more conveniently conduct digital currency transactions and sell coins. The following will introduce you in detail how to add Polygon to your MetaMask wallet, allowing you to easily master the steps of selling coins.

#How to sell coins on the Polygon chain?

There are two ways to add the Polygon network to your MetaMask wallet. One is to add it manually, the default way. The other is to use the Polygon wallet interface to quickly add the Polygon network to MetaMask's network list.

Step 1: Add Polygon to MetaMask

1. Please click the [Switch to Polygon] button at the top to operate. Be sure to connect the MetaMask wallet.

#2. You will see the pop-up window of the MetaMask plug-in, showing the Polygon network details. Click [Approve].

3. The operation is completed. Polygon network has been added to MetaMask. Now, MetaMask needs to be switched from the Ethereum mainnet to the Polygon network. You can click [Switch Network] to perform the operation.

4. MATIC can now be seen in the MetaMask wallet.

Step 2: Use MetaMask to bridge MATIC to Ethereum

1. Enter the [Bridge] interface and click [Withdraw]. Select [MATIC Token] in the token list, enter the amount, and click [Transfer].

The system will automatically select [Plasma Bridge] as the transfer mode.

2. Read the important tips and click [Continue] when you are ready.

#3. You will also see the estimated gas fee for this transaction. If you are ok with the fuel cost, click [Continue].

4. Please verify the transaction details before clicking [Continue].

#5. The system will display a MetaMask pop-up window for you to confirm the transaction. Click [Confirm] to see that the tokens are being transferred.

You need to manually confirm the three transactions of Plasma Bridge transfer. The first withdrawal is from the Polygon wallet, which may take up to 3 hours.

#6. Reaching the checkpoint indicates that the transaction has been verified on the Ethereum blockchain. The challenge period can only begin after the second transaction is confirmed. This measure can improve the security of withdrawal transactions.

#7. After the challenge period is over, just click [Continue] to transfer MATIC tokens to the MetaMask wallet.

How about a Polygon chain?

Polygon, formerly known as MaticNetwork, is a blockchain scalability platform and framework for connecting and building Ethereum-compatible blockchain networks. The network also calls itself the “Internet of Blockchains for Ethereum,” as one of Polygon’s main missions is to aggregate scalable solutions to support the multi-chain Ethereum ecosystem.

The Polygon network is native to Ethereum and interoperable with all existing and even future Ethereum infrastructure, while providing a framework to interoperate with other layer 2 solutions, sidechains, and sovereign blockchains.

Therefore, Polygon Network is also classified as a layer 2 aggregator, aiming to create a multi-chain ecosystem of Ethereum-compatible blockchains with superior interoperability.

Layer 2 solutions refer to frameworks built on the underlying chain to relieve its stress and complement its fundamental pain points. Polygon is an aggregator based on Plasma, a layer 2 solution for Ethereum that provides a framework for building decentralized application (dApps) chains with enhanced security, scalability, and speed. Down. The Plasma framework is one of the driving developments behind the mass adoption of blockchain technology.

Polygon has its own Plasma implementation in so-called Polygon Plasma Chains. In addition to forming the framework for dApps, Polygon PlasmaChains can move transactions from the main blockchain into secondary chains for cheaper and faster transactions.

The content above is the editor’s detailed explanation of how to sell coins on the Polygon chain. Polygon aims to transform Ethereum into a complete multi-chain system or Internet of Blockchains, similar to ecosystems such as Polkadot and Cosmos, with the added advantage of Ethereum’s powerful protocol and security. In the early days, the ecosystem was called MaticNetwork, a simple scaling solution based on Plasma technology that processed transactions with low gas fees. Polygon has evolved into a more sophisticated platform, and the project has been working hard to build and launch a fully interoperable blockchain.
