What is Polygon?
Polygon is an Ethereum sidechain (also called "Layer 2", Ethereum being the main Layer) that has orders of magnitude faster transactions and lowers fees. Here are some highlights:
0.01 MATIC can pay for approximately 20 transactions (1 MATIC is approximately less than 1 USD, but that can vary at any time)
Transactions take just a few seconds up to one minute to be confirmed
It has the most extensive user base of any other Ethereum Layer 2
The most popular Ethereum blockchain apps and games, such as Uniswap, OpenSea, Curve, Sandbox, Lens Protocol, and others, run on Polygon too
Securing Polygon tokens and NFTs in Zengo
You can send and receive the following Polygon tokens and NFTs directly to your Zengo Polygon wallet address and store them securely:
Polygon MATIC, WETH, DAI, USDT and USDC
And any Polygon NFT
Important note: Zengo protects you by filtering spam NFTs
You can distinguish Polygon from Ethereum assets by means of a network icon and if it is a token by the appended "(Polygon)" in the name.
Receiving Polygon tokens and NFTs
If you want to receive a Polygon token, make sure that you have selected the token that has the Polygon network icon and "(Polygon)" in the name.
Acquiring Polygon MATIC tokens to pay for transaction fees
Sending tokens on Zengo is free of charge, but a transaction fee must be paid to the polygon blockchain network like in any other service. On Polygon, those transactions fees are very low compared to Ethereum.
To pay for Polygon transactions you need to have the native Polygon MATIC token in your Zengo wallet. This is similar to how you need ETH to pay for Ethereum transactions.
You can obtain some native Polygon MATIC in the following ways:
Send Polygon Matic token over to your Zengo Polygon MATIC address from another wallet or exchange of your choice
Buy within Zengo using one of our on-ramp providers (coming soon)
Trade an ERC20 token for it in Zengo (coming soon)
Swap a Polygon token such as ETH, DAI, USDT or others for Polygon MATIC using Polygon's official bridge (guide below)
it is a free transaction and takes ca. 1-2 minutes, but you need to have some Polygon tokens
Bridge Ethereum (ERC20) MATIC to Polygon MATIC using Polygon's official bridge app (guide below)
it requires paying two transaction fees and takes up to 20-30 minutes
however you need only ERC20 MATIC on Ethereum
Below we will go into more detail on the last two options.
How to swap a Polygon token for Polygon MATIC
In order to swap a Polygon token for Polygon MATIC, you first need to have a Polygon token in your Zengo wallet.
You can acquire it by sending one of our supported Polygon tokens to your Zengo Polygon address, buying in Zengo (coming soon), or trade something for it in Zengo (coming soon).
Let's assume you already have one of the supported Polygon tokens in Zengo. First head over to the Polygon Swap page and connect your Zengo wallet on the Polygon network. For more details on how to use WalletConnect to connect to dapps on a specific network head briefly over to this article.
Once you're connected, you'll need to select one of your Polygon tokens (Polygon ETH in this case) and choose the amount of Polygon MATIC you want to receive. Then, you need to confirm two transactions from your Zengo wallet: 1) Approve and 2) Transfer
This transaction will take only a few seconds and does not cost anything. As a result you should receive Polygon MATIC and be able to pay for Polygon transactions 👍
How to bridge Ethereum (ERC20) MATIC and convert it to Polygon MATIC
In order to bridge ERC20 MATIC and convert it to Polygon MATIC you first need to have ERC20 MATIC in Zengo. You can acquire it by sending it to your Zengo address, buying in Zengo or trading something for it in Zengo.
Let's assume you already have some ERC20 MATIC in Zengo. First head over to the Polygon Bridge and connect your Zengo wallet on the Ethereum network. For more details on how to use WalletConnect to connect to dapps on a specific network head briefly over to this article.
Once you're connected, you'll need to select your ERC20 MATIC from the assets dropdown and type in the amount you'd like to bridge over. Then, you need to confirm two transactions from your Zengo wallet: 1) Approve access to your chosen token to be bridged and 2) Confirm the bridge transfer.
1. Approve access to your ERC20 MATIC in Zengo
2. Confirm the deposit in Zengo.
3. After the deposit is completed your Polygon MATIC will be underway.
ℹ️ Note: Once this final transaction is completed in ca. 20-30 minutes you should receive Polygon MATIC and be able to pay for Polygon transactions 👍

Frequently asked questions on Polygon.
What apps can I use on Polygon?
Polygon offers a wide range of services and apps you can use and many popular apps built for Ethereum works on Polygon but with the advantage of lower fees and speed: for example decentralized exchanges like Uniswap or NFT apps like OpenSea. You can also use social media apps like lens protocol and upgrade your Reddit avatar
I cannot see my Polygon Tokens. Why?
Zengo supports natively Matic, USDT, USDC, DAI and WETH but you can receive any polygon token on Zengo. To view all your tokens and be able to send them you can connect Zengo to any DEFI apps like a decentralized exchange (eg Uniswap).
I do not have Polygon Matic tokens. What should i do?
Read our guide above. You can either obtain those tokens by way of swap, bridge or purchase and trade (soon available in Zengo)
I cannot connect my Zengo wallet to a Polygon app. Why?
If you try to connect to a polygon app and it does not work, you need to make sure the Polygon network is selected on Zengo after you scan the QR code.
If that does not work even after doing the above, please head to the app connections screen ("Account" > "Connections"), find the app you are trying to connect to, disconnect the app and try again.
Can I use Zengo to deposit my NFTs on Polygon?
Yes. They will show in your NFT gallery.
