Is there any websocket ethereum provider? Except etherscan one. Maybe there are paid wss subscriptions?

Use Infura.io to connect to different blockchains. You will need an account and project id.

Steps to create an Infura.io Project and remarks

1) Open Infura.io page and sign up for an account. On your dashboard, you now can create a new project.

enter image description here

2) Change the endpoint to Kovan and directly copy the endpoint URL for connecting to blockchain.

3) The web socket URL is slightly different from the http interface — the correct pattern for web services is:

wss://kovan.infura.io/ws/v3/{your-infura-project-id}  

Please, be aware that your personal API key to use Infura should be secret. So, don’t give it away to anyone else.

  • Nothing special to access: var web3 = new Web3(Web3.givenProvider || 'wss://mainnet.infura.io/_ws');. You can track some of the websocket talk on their GitHub. Commented May 25, 2018 at 3:29

Have you tried Fiews?

https://fiews.io/

I use them for my Chainlink Node and they work great!

the best one for me is Fastlynode, they provide private node but for the moment they only provide private node for binance smart chain, you can use this discount code FASTLY20 to get 20% OFF
