Is there a single webpage that lists the current transaction fees for the major blockchains, like BTC, ETH, solana, avalanche, matic, BCH, BSC, etc?
There's no site like that but i guess this can also become an opportunity for someone to create fees comparison site. I never see this before. The only thing that you can do manually checked it by opening explorer from one to the another blockchain and you will see the comparison between those blockchains.
As far as i now it's also easy to create this site as you can use api to take the latest transaction fees from the blockchain.
