How to Sell an NFT Without Gas Fees on OpenSea

Non-fungible tokens (NFTs) have exploded in popularity, but selling them on marketplaces like OpenSea can incur significant gas fees. This guide will teach you two methods to sell an NFT on OpenSea without paying gas fees:

Method 1: Using Polygon Blockchain

1. Connect Metamask to Polygon: Install the Polygon network on your Metamask wallet by adding the following network details:

   • Network Name: Polygon Mainnet
   • New RPC URL: https://polygon-rpc.com/
   • ChainID: 137
   • Currency: MATIC
2. Transfer NFT to Polygon: Send your NFT from your current blockchain (e.g., Ethereum) to a Polygon wallet address.
3. List NFT on Polygon: Create an OpenSea account and connect it to your Polygon wallet. Upload your NFT, select Polygon as the blockchain, and set the price in MATIC.
4. Avoid Gas Fees: Completing these steps using the Polygon blockchain eliminates the need for gas fees during the listing and selling process.

Method 2: Using Seaport Protocol

1. Install Seaport: Install the Seaport Protocol contract into your Metamask wallet. The contract address can be found on the Seaport website: https://seaport.xyz/.
2. Seaport Orders: Create a Seaport order in your Metamask wallet, specifying the NFT you want to sell and the price in ETH or MATIC.
3. Share Order: Share the order with potential buyers. Buyers can accept the order using the Seaport website or third-party applications that support Seaport.
4. Gas-Free Settlement: When a buyer accepts the order, Seaport will automatically match the transaction and facilitate the NFT transfer. This process bypasses the standard OpenSea exchange process, eliminating gas fees.

Additional Tips

• Consider using a gas-saving browser extension like MetaMask Swaps to minimize gas fees when interacting with smart contracts on Ethereum.
• Optimize the timing of your NFT sale by monitoring gas fee fluctuations. Generally, gas fees are lower during off-peak hours.
• Bundle multiple NFTs into a single sale to reduce the gas cost per item.
• Explore alternative marketplaces like LooksRare and X2Y2 that offer low or no gas fees for NFT transactions.
