Add stats calls for different blockchains. For more information see this page.

On the following:

• Stats on multiple blockchains at once
• Bitcoin-like blockchain stats
• Ethereum-like blockchain stats
• Ripple-like blockchain stats
• Stellar-like blockchain stats
• Monero-like blockchain stats
• Cardano-like blockchain stats
• Mixin-like DAG stats
• Tezos-like blockchain stats
• EOS-like blockchain stats
• Cross-chain token stats
• Omni Layer stats
• ERC-20 stats

🔖 Feature description

To make sure the user is sending a valid address(es) for a specific cryptocurrency. There should be somthing that is fast for validating but also strict.

🎤 Pitch

A solution is to use either DFA or NFA. Because NFA could be kind of time-consuming, I think that DFA is the best option.

DFA for the following crypto (must also support multi-signature addresses):

• Bitcoin
• Bitcoin Cash
• Litecoin
• Bitcoin SV
• Dogecoin
• Dash
• Groestlcoin
• Zcash
• eCash
• Ethereum

That is enough to start with.

Q: How can I test that the DFA is working for X crypto?
A: Use Database Dumps from Blockchair.

• I checked and didn't find similar issue

The functions in "client.go" needs tests of a happy day scenario. Use mockups for this task. Like from https://github.com/stretchr/testify. Should have a unit test coverage of +80% for the file.

See this page for what is request cost. Make somthing that could simulate the run of a fucntion(s), without actually sending the request, to calculate the request cost in total or for each request.

Please share your thoughts on how it can be implemented and questions in this issue.

What is this issue about?
Improve documentation on Gitbook. Users who want to contribute need a Gitbook account and will get an invite to the team as a writer. Just ping me in the issue for access.

Special notes:

Does this issue introduce a user-facing change?

The rate limit is not properly developed. Needs some adjustment to work properly. Blockchair does not support rate limit headers. Therefor it is hard to determend the correct rate limit for users not using an API key. Users with API key can call Premium API for stats. Should continue to support Concurrent and Sleep/WaitTime. Should not need any external modules/packages for this.

Key points:

• 1440 requests a day for users without API key
• 30 requests per minute for users without API key
• Soft limit of 5 requests per second on both free and paid plans
• The daily request counter is reset at 00:00 UTC every day.
