Hello there. Is there a limit of request for my dapp on Ethereum network?

Depends on your rpc provider

Your own node? Then none

I mean, I set up an dapp with web3 with default provider, I did not use any rpc provider.. i dont understand how it works. Is it not enough to set web3 with network name and ID?

There is no 'default provider'. You're probably using infura

I sign transactions with metamask

For an nft mint dapp

What about other functions?

Like static calls and stuff

Metamask use infura btw

I use hashlips-nft-minting-dapp as a template, no provider specified

Hmm can you share the code? I'm pretty sure its using infura as well

https://github.com/HashLips/hashlips_nft_minting_dapp

I think I understand now. So basically all static call I have to do will be called with Infura or Alchemy or whatever, but because minting is a transaction that needs to be signed , metamask take cares of it. Am I right?

Yep its connecting to metamask

Actually the dapp is using mm for static calls as well. You need to connect wallet to load anything

Thanks for taking time to answer to me. I really apreciate, mate! ❤️
