EASY Trick I did to save on Gas fee

USD to ETH High transaction fee

For instance, I like to invest initially $20 to buy cheap NFTs just to have an experience of it. However, most NFTs our transacted in Ethereum blockchain, and this requires ETH. But as well an expensive gas fee just by depositing ETH to your MetaMask Wallet. And in Binance, which is perhaps one of the platforms with the cheapest fees, you would need 0.002 ETH, about $6, just to fund your MetaMask wallet of $20 worth of ETH. Aside from the gas fee, you’ll need to pay when buying your first NFT then, nothing would be left. So I did this.

EASY Trick I did to save on Gas fee

Convert MATIC tokens to WETH

The way this would work is we’ll take advantage of the Polygon blockchain. Actually, MetaMask and OpenSea recommend using Polygon for beginners, as buying NFTs with it would not cost you more than a fraction of a cent. And with that, we’ll be getting “WETH” or “Wrapped Ether.” This could be converted back to ETH. Going back, instead of directly buying ETH or “WETH,” we’ll buy MATIC tokens, deposit it in MetaMask, and then convert it to “WETH”. This would let us save gas fees.

EASY Trick I did to save on Gas fee

Buy MATIC tokens in Binance

So, in Binance, on the Buy Crypto page, we’ll click on the ‘Buy.’ Then, fill up the details of like spend $20 and then choose the MATIC in ‘Receive.’ Next, hit ‘Continue.’ This would send you to a secured payment by Credit/Debit card, and fill up the details. After that, click ‘Continue’ and ‘Confirm.’ This will have a $0.4 fee then after that. Wait for the transaction to get thru then you’ll receive the MATIC tokens in your Binance Wallet.

Deposit MATIC tokens for Metamask

Next, we’ll deposit it to our MetaMask Wallet. So, in the Binance Wallet drop down, click on ‘Fiat and Spot’ and click the MATIC token. There you’ll put your Polygon Network MetaMask Address make sure you put the right one.

Get your Polygon Network address

To get your Polygon Network address, go to ‘’ And there, hover your mouse in the upper right header,’ Use Polygon.’ Then in the drop-down, click ‘Add Polygon POS Network in MetaMask.’ MetaMask would pop up, and click ‘Approve.’ Then ‘Switch Network.’ 

Withdraw MATIC from Binance to Metamask

Once you open the MetaMask Wallet, you can get the address and copy-paste that into Binance. Then, click ‘Network’ and select ‘MATIC.’ Just here, you can see the big difference in fees. Next, fill up the ’Withdraw amount,’ in my case, I sent 13.76 MATIC tokens. And with just 0.1 MATIC as the fee, which is around $0.13, I would only spend $0.53 to fund my MetaMask. With all this filled up, click ‘Withdraw.’ In order for this transaction to proceed, confirm it with the security code sent to your mobile number and email registered in Binance. Wait for a while, from 4-10mins then once the transaction is completed, you’ve just now transferred funds to your MetaMask wallet, costing only $0.53.

Convert MATIC to WETH

Then we just need to convert it to ‘WETH.’ So, go to ‘’ There, connect your MetaMask wallet, and then proceed in swapping the MATIC tokens to ‘WETH.’ In my case, I converted my 13.8 MATIC tokens into 0.624 ‘WETH.’ I clicked ‘Swap’ and once the transaction is complete the I’ll be receiving 0.588658 ‘WETH’ in my MetaMask wallet. Overall we spent $20.4, and we’ll receive $19 in our MetaMask wallet, which was way lot cheaper. With all that, we can now buy our first NFTs.
