In this Etherscan Tutorial, we'll take a look at how the Etherscan API makes it easy for us to query the transaction history for an address. This will help us build a more reliable system. OpenSea is annoying. Their site goes down all the time, everyone complains about their fees, and you have to fill out an application and wait for days for a response if you want an API key.

Could you please share what you are using instead of IEX?
I have a very similar use case where I can now simplify my code. Thanks for sharing this video.

Great, but my destroy task is not working?
did you ever fix this? I'm having the same issue, can't seem to figure out why the tasks persist after @task.destroy is called.
cool video)
I get dat and time/label fields to load from the API request just fine, but the 'price' or 'close' is all null -- anyone have any tips to resolve this? (also if i try: data: data[data.length-2] i get 'close' undefined property runtime error) other than that great video series!
Thank you for the upload. Much appreciated.
Thank you!
Bro Just start it again
one of the best rails video. I do appreciate . Would you make another series for using rails 7 ? can be some clone or ecommerce. we would benefit from your knowlegde.
Onclick litener not working in rails 7
Event issue, not in my vs code
Thank you mate!
So, you are creating virtual box inside a virtual box?
That too was my take away. Initialized a linux server in the VB.
connect_internal': A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. - user specified timeout (Redis::CannotConnectError) i face this error during ActionCable broadcast a message , how i can can solve this ?
kindly anyone know give me answer
Great video, very thorough and complete. Really helped my understanding thank you
thank you
Great Content man. Really helped
Awesome tutorial, the whole series is excellent! Just for anyone who is folloing along and wondering why their program isn't behaving the same way: Setting up the NavBar at ~12:45: In Bootstrap5 ml (margin left) is replaced by ms (margin start), so the code would be as follows: <ul class="navbar-nav ms-auto"> Setting up the Sign out at ~17:20: In Rails 7 when changing the method from get to destroy, we no longer just call method. You can replace the method: :delete portion of the code with - data: { turbo_method: :delete }, so it should look as follows: <%= link_to "Sign out", destroy_user_session_path, data: { turbo_method: :delete }, class: 'nav-link' %> Good luck!
Where can i find part 11?
heyy, is this an app or a website? please reply

Please what terminal are you using? Because I’ve downloaded everything and still I don’t know what terminal to use
It really shouldn't matter what terminal you use. Are you referring to the terminal app, or the shell? He's using iTerm2 on macOS for the terminal app, and I assume it's bash for the shell, but it should be the same for zsh or whatever.
Dumb Question, but here it is Where are you adding prices?
Finally i understand this. Thanks man
how to open the console?
right click and see for the inspect button.
very helpful
Source code please🙏
Model.find() no longer accepts a callback :/ it's deprecated in Mongoose 7.x

Hi How could I change the name of the buttons "Update Project", "Create Project", etc., independently? Since the form that is rendered always brings the own name of the method, where could I change that?
