How to Buy, Mint and Sell NFTs on Polygon in 2026: Wallet, POL Gas and Fees

To buy, mint or sell an NFT on Polygon you need an EVM wallet set to Polygon Mainnet (chain ID 137) with some POL for gas. You also need a marketplace that still supports Polygon. OpenSea lists Polygon among its supported chains, and its help center gives a 1% fee on NFT sales. Older guides tell you to pay gas in MATIC and to buy on Magic Eden. Both pieces of advice are out of date. Polygon PoS has used POL for gas since September 2024. Magic Eden said on Feb. 27, 2026 that it would stop supporting Polygon assets.

What changed

Gas is paid in POL, not MATIC

Polygon Labs says that "since September 2024, every transaction that takes place on Polygon PoS has used POL as the native gas token" (Polygon blog, Sept. 3, 2025). The same post says about 99% of MATIC on the network had been converted to POL by then. Holders who still have MATIC on Ethereum can convert it 1:1 through the Polygon Portal.

If your wallet still shows "MATIC" for Polygon, you most likely added the network before the switch. Change the currency symbol in the network settings to POL, using the values below.

Magic Eden has left Polygon

Decrypt reported on Feb. 27, 2026 that Magic Eden CEO Jack Lu said the marketplace would stop supporting Ethereum-compatible assets, including those on Polygon and Base, and would keep only Solana assets. Trading was set to end in under two weeks, and the wallet would drop those assets at the beginning of April 2026. Guides that walk you through buying Polygon NFTs on Magic Eden, or that recommend the Magic Eden wallet for Polygon, no longer apply.

Set up the wallet

Polygon's support page lists these values for adding the network by hand:

• Network name: Polygon Mainnet
• Chain ID: 137
• Currency symbol: POL
• Block explorer: https://polygonscan.com/
• RPC URL: pick one from Polygon's RPC endpoints page (for example https://polygon.drpc.org). Polygon notes that public endpoints are free but may be rate-limited.

Any EVM-compatible wallet, such as MetaMask, accepts these values. Hold a small amount of POL on Polygon before you start, because buying, minting and approving all cost gas.

How gas works on Polygon

Polygon PoS uses EIP-1559 fee pricing. Polygon's developer docs describe two parts:

• Base fee: set by the network from how full the previous block was, and burned.
• Priority fee: an optional tip to the validator, capped so that base fee plus tip never exceeds your maxFeePerGas.

The fee you pay is the base fee plus the priority fee. OpenSea's help center says gas is not paid to OpenSea, OpenSea does not control gas prices, and failed transactions are not refunded. Read the gas estimate on your wallet's confirmation screen before you approve.

Buy an NFT

1. Connect your wallet to the marketplace and confirm the collection is on Polygon. Marketplaces such as OpenSea list many chains, and an Ethereum item with the same name is a different asset.
2. Buy at the listed price, or make an offer.
3. Approve the transaction in your wallet and check the gas line.
4. If the transaction does not show up, look it up on PolygonScan. Our PolygonScan walkthrough explains how to read the result.

Mint an NFT on OpenSea

OpenSea's help center (updated Aug. 22, 2025) splits minting in OpenSea Studio into two parts.

Deploy a contract

1. Open Studio, click Create new, then Create Collection.
2. Add a logo, contract name and token symbol, and choose an EVM chain (choose Polygon here).
3. Click Publish Contract and approve the transaction. This costs gas.
4. Optionally edit collection details and set creator earnings.

Create the item

1. Upload the media. Every item in a collection must use the same file type.
2. Name the item and set its supply. A supply of 1 makes it unique.
3. Optionally add a description, external link and traits.
4. Click Mint and approve in your wallet.

The contract name and token symbol cannot be changed after deployment, and NFTs cannot be moved between collections later. Check these before you publish.

Sell an NFT on OpenSea

According to OpenSea's help center (updated July 17, 2025):

• List from your profile, the item page or the collection page, then click List item.
• Set your own price, or match the collection floor or a trait floor.
• Listings can last from 15 minutes to 6 months.
• You can reserve a listing for a single wallet or ENS name (a private listing).
• On EVM chains, listings and offers need no gas except a one-time approval.

Fees, as OpenSea lists them

OpenSea says its fees "are subject to change at any time" and that it may waive fees on some sales. Older articles still quote a 2.5% sale fee, which no longer matches OpenSea's fee page.
