Thanks for your submission, could you please tell more about Tatum?
When is launched, for how long have been live?

Fair questions!

It came out of stealth ~2 years ago, and recently raised series A. Marketing hasn't started yet, so it's a bit under the radar.

We have a native RPC access as well as a universal blockchain API. Feel free to create an account if you want to test. There is a free tier, that's only rate limited - none of the advanced features are gated.

I recently heard about Tatum, and I already created an account on the platform. While Tatum has plenty to offer, its connection process is not the same as other node providers. It requires an API key to connect to its RPC node, which is not compatible with wallets such as MM. Unfortunately, we cannot accept Tatum at this time.
Thank you for understanding!

@arddluma, Again, thanks for your time in maintaining this list. It's a fantastic tool; I was reminded of it today after I met a user who mentioned it! And it wasn't the first time I heard someone mention it, so it's gaining traction.

For Tatum, Is the issue that access requires an x-api-key specifically? I ask because I know most RPC providers require some sort of secret key. For example some of my endpoints for my rpc latency testing tool:

quicknode: https://broken-icy-sun.discover.quiknode.pro/79f6cbd2ce4e09eae9000884b0a92946c17bbe43

Tatum actually does not necessarily require an api key to be included in a request: An IP address can be associated with an account. The two other methods do require an x-api-key specifically, but it can be in either a header or in the path as a parameter like this:

In any case, very cool tool, and I'll be referring customers to it when the 41 blockchains (and their testnets) we support don't provide the coverage they need. 👍
