How to take cryptocurrency?

It is necessary to take the crypt on the website. The question is, how can I do this without API other services? Let's say I want to add a crypt which may not be the IPA. Is to download the entire blockchain and auto program all the confirmation test or there is a simpler way?

Not really but thanks. It's the only way to do always.
In other cases, the "accumulated" crypt can silently go along with the service offline.

If you want no third-party services in any way.

You can simplify the decision and request the balance and transactions on the receiving purse through the open nodes (for broadcasting, for example, Infura), but no one will guarantee the reliability of the data. However, private keys from the wallet in any case you need to store.

IMHO the correct decision was written. Purses generate for yourself transaction through Infura, and check status via any public API to check balance (you trust of course).
