Update to the Infura API Authentication

[StefH]

This message is being sent to communicate a very important change to the Infura service that will impact all users of the Infura API endpoints.

We recently published a blog post introducing the new Stats section of the Infura Dashboard. Along with the announcement, we provided the schedule to deprecate our legacy API authentication. Requests will start to require a Project ID generated from the new Infura Dashboard. More information on how to send requests using a Project ID can be found in our docs. Here is the timeline:

January 23, 2019, 20:00 UTC
Requests using Dashboard-generated Project IDs will be prioritized over legacy keys during periods of high traffic activity. Legacy keys may experience slower response times.

March 27, 2019, 20:00 UTC
Support will officially stop for all requests not sent using an Infura Dashboard-generated Project ID.

This transition will ensure that our service reliability and performance is consistent for all users. For more information about the changes please see the blog post linked above.

What do I need to do?
If you haven’t done so already, create an account at https://infura.io/register. Once you have created your account and logged in to the Dashboard, simply create a new project, and your Project ID (and associated Infura API endpoint URLs) will be generated. Replace the Infura URL in your code with the newly generated URL.

You may also create multiple projects to isolate traffic for multiple dapps/use-cases. Stats can be viewed in aggregate or on a per-project basis.

If you maintain a library that leverages Infura, please reach out directly to us if there is anything we can do to help you with this transition.

How do I know I am using the correct API endpoint URL?
Prior to July 2018, your Infura API endpoint would have looked like this:

https://mainnet.infura.io/[YOUR_KEY]

The updated API endpoint using the new authentication generated in the Infura Dashboard will look like this:

https://mainnet.infura.io/v3/[PROJECT_ID]
