Bitcoinjs-lib: How to broadcast a transaction?

[vekexasia]

Hello,

I'm new to BTC and wouldn't want to screw things up. Lets say I can craft and sign a new tx with this library. How do I send it to the network?

Use this: https://blockchain.info/pushtx
or
https://blockr.io/tx/push
or similar.

(You can push with multiple sites and it's safe)

If you have a bitcoind node: sendrawtransaction, or use an API as @arunoda suggested

Hello @arunoda it seems i cant find an API for any of that.

just regular http form.

POST https://blockchain.info/pushtx

Half the links on this thread points to Coinbase's API on my end..
So just to be clear, your official recommendation is to use a third-party API to broadcast?

3rd party, 1st party, it doesn't matter, bitcoinjs-lib doesn't connect to the bitcoin network, so you need to use something else. But that something can be your own bitcoind node.

Ahh alright, makes more sense now. Still getting the hang of things :)

Hi.

I have a bitcoind but I don't know how to broadcast a transaction.

Thanks.
