Good day guys,
I would like to know if there is another alternative for wallet api for bitcoin? Currently i'm using block.io but i am not convinced with their services and security. i was planning to use coinbase's BTC wallet api.
I hope to hear from you masters if there is any alternatives that I should try as a backup just incase block.io one day decides to go down... just need alternative BTC wallet API...
Thank you!!!!

You can use blockchain api or coinbase. In my opinion, should choose services that have a large user and good ecosystems!
