You want to deploy NFT game / dApp on Side chain, then there are two biggest options right now: Polygon and Binance Smart Chain (BSC), both are basically Ethereum layer-2 blockchains. So how to decide which blockchain you should use? I think the most important is: Transaction Fee

As you may know, BSC is more expensive than Polygon, but how much times? As both chain are Ethereum layer-2, there is a very easy way to calculate this:

Go to both blockchain explorer of both Chain:

On each site, click on a random transaction and view the Gas Price of the transaction, for example at the time I write this post:

So we can see that the Gas Price for BSC is 5 Gwei, for Polygon is 1 Gwei

We also know 1 BNB = $486 and 1 MATIC = $1.42 (from

Then, the transaction fee on BSC compare to MATIC is: (486 / 1.42) * (5 / 1) = 1711 times more expensive.

Note that this value may change, there are two factors effects on this:

  • The price of 1 BNB and 1 MATIC
  • The AVG Gas Price of the chain: If more people using the chain the gas price become more expensive.
