Is it widespread for the positioning to instantly ship the acquired cash to its superwallet (grasp node) upon X confirmations?
No. By no means and would usually be thought of very dangerous follow as in bitcoin you do not spend from addresses however from transactions, so “accumulating” in a single deal with would not actually work. Sending from that deal with would once more should reference all of the forwarded transactions. (There are particular instances like inexperienced deal with in its authentic implementation however no, that is a factor of the previous.)
And the way would u know when a cost is shipped to one of many derived addresses?
You watch the bitcoin community? Both by way of proxies or with a full node. Take a look at the perception.bitpay.com API.
Let’s assume the case with a derivation path of m/okay’/0/i, the place m is the grasp node, ever person has a okay node and that i is his i’th buy transaction.
I might strongly advise to carry that logic within the server, solely.
eCommerce appears like one central server, so there’s actually no huge have to fan out an excessive amount of within the HD pockets construction. You must also look into BIP44 on transaction discovery.
Your online business logic has to maintain monitor what objective an deal with has but when that web site by no means has to ship refunds, it might sometimes solely have an prolonged public key. Now if it receives to
m / 44' / 0' / i' / 0 / j
any bip44 appropriate pockets would discover and be capable of spend the funds for those who supplied it with not less than the xpriv key for
m / 44' / 0' / i' / 0
however sometimes
m / 44' / 0' / i'
One minor factor it’s important to maintain monitor of, is the hole between addresses that do not obtain a cost. In case your server observes a spot of greater than 20, you would need to assist your pockets to search out these funds if it is strictly bip44 which might solely bridge gaps as much as 20. In case your final transaction is to index 1220 and you do not see transactions to 1255 and 1257, you could possibly ship a satoshi to 1239 and your pockets would discover the remaining.
