Look up address balance for a wallet for Bitcoin on QuikNode
December 16, 2020
If you're running your own bitcoin node (such as bitcoind or bcoin) there is a chance you will want the ability to look up the balance of an address that you do not own. The first time this happens, you might create a watch-only wallet and add the address in question. This works, but then you need to add another one, if you've built a wallet and you're running a (non-spv) light client then this strategy won't scale - your bitcoin node will run out of memory.
That's why we've made an add-on available for customers who wish to access the bitcoin network, a simple address balance index. It allows you to supply a bitcoin address (such as 1LPE9YTzDBQF5vZNnKcTJejstfsS8Z6icx) and retrieve its current balance!
