If you want to sell your NFTs on the Opensea marketplace without paying crazy high gas fees with Ethereum then the Matic option is for you. After you have minted your NFT, there is an option on the item's page under
Trade to transfer to Matic mainnet. There is some setup involved first before you can use this option.
Please note: this feature is still under heavy development. If you get stuck or have any questions reach out to us on Discord!
- Metamask: https://metamask.io/
- Ethereum in your wallet (gas fees)
1. Getting Matic
You can either buy Matic off a centralized exchange like Binance or exchange some Ethereum for it using a decentralized exchange like Uniswap. There's a gas fee to do the swap, hopefully it's not too much. If Uniswap asks if you want to add MATIC to Metamask say yes and add token, your balance will then appear in your wallet.
2. Switching Metamask Networks
The easy way to do this is to go to https://quickswap.exchange/ and then click
Switch to Matic at the top right next. This will open up Metamask with Matic's URL configured for you. You can verify the settings or do this manually as well: https://docs.matic.network/docs/develop/metamask/config-matic/.
3. Move funds to Polygon Network
Next we have to move the Matic from ETH mainnet to Polygon network (Layer 2). Go to https://wallet.matic.network and login via Metamask. Now click the button
Move Funds to Matic Mainnet.
FROM section, change from Ethereum to Matic token. Add however many you want to transfer to the Matic network then hit transfer. This process will typically take 7-8 minutes and cost some gas. Hit continue and wait.
4. Transfer NFT to Matic Network
At this point you are ready to transfer any NFT that you mint to the polygon network. If you already minted something, head over to the asset's page directly or from your profile on the Webaverse website.
Make sure your Metamask is set to Matic network, then:
- Open Metamask and click the network button
- Select Matic Network (configured from step 2)
Then head to the page for your asset and underneath Transfer hit
Transfer to polygon. It will open up Metamask to sign the transaction.
After you signed the transaction, wait a few moments for the opensea page to be updated. Check https://opensea.io/account?tab=activity to see when it shows up.
5. Selling on Matic Opensea
Go to https://matic.opensea.io/ and click login on the top right to sign in with your Metamask. To sell something in the Webaverse ASSET store you just need to go to My Account located at the middle top of the screen. Find something you want to list and hit sell to set a price.
Your item will now be discoverable in the ASSET tab with the Webaverse logo on https://matic.opensea.io. Cheers!
