I'm building a project that works with different cryptocurrencies (bitcoin, eth and tokens, ripple, litecoin, monero and others).
It's not a wallet, but part of the functionality is similar to an SPV wallet, in that the client contacts a server for balances, unspent TX and is able to push transactions on the server.
Ideally for now at least I'd rather not run a full node of each of the blockchains.
Does anyone knows a good service with support for multiple cryptocurrencies for this?
Thanks.
As already suggested by SFR10, Blockchair API is your best option for what you are looking for. Since you are making a soon to be a product project, then it is better to use resources that are premium as well yet maintaining the efficiency. If you only wanted some limited API calls and features, lookup for free APIs out there but you might not have the best result you first expected to have. Goodluck dude!
