Question:

What are the usage limits for metamask?

Sophia: 2 weeks ago

Metamask loads data from the blockchain into my browser, it's a light client.

How much data can I load until it stops. There must be some type of resource limit involved here...

I'm sure metamask doesn't want us using the client as a CDN to deliver large resources.

Metamask uses Infura for its backend to interact with the blockchain. Currently Infura does not enforce any limits right now. But please do give us a heads up if you're launching a huge dApp or doing a token launch, so we can help you guys out with it.
