How to use bitcoinjs-lib with Regtest? I was trying to use the bitcoinjs-lib (1) with my regtest network. More specifically I was trying to build a tx with TransactionBuilder but it gave me a 'transaction has no matching Script' exception. 

In a closed github issue (2) I find out that it's possible to specify the network (network.testnet), but I can't find any documentation related to regtest. I just want to create and broadcast a raw tx created with bitcoinjs to my regtest network. 

So, has anyone talked to a regtest network with bitcoinjs-lib successfully? If not, what other libs would you recommend for the satoshi client? Thanks.

Oops! Noob mistake.

I thought that testnet and regtest had different version prefixes (not compatible) but they are (the bitcoin wiki and bitcoin developers page doesn't clarify this, though). So I went into a npm package that added dogecoin and litecoin testnets compatibility with bitcoinjs-lib (it's called bitcoinjs-testnets).

But the solution in the second Github link that I posted works. 

Here I repost the text:


  Just want to give some feedback that may help new users in the future.
  I lost a lot of time debugging an issue that is probably extremely
  obvious to some, but it was not directly obvious to me.


var bitcoin = require("bitcoinjs-lib");
var keyPair = bitcoin.ECPair.fromWIF("mywif", bitcoin.networks.testnet);
var txb = new bitcoin.TransactionBuilder(); txb.addOutput("myaddress", satoshis);  // &lt;---- this will fail with "has no matching Script"



  Because of the error message I came to the conclusion that I was doing
  something fundamentally wrong creating the transaction. In the end, it
  turns out I just needed 


var txb = new bitcoin.TransactionBuilder(bitcoin.networks.testnet);



  Feel free to close this, just wanted to share my experience


I wish my noob experience has helped you! (pardon for my english).
