blue-app-btc
Bitcoin wallet application for Ledger Blue and Nano S
This follows the beta specification at https://ledgerhq.github.io/btchip-doc/bitcoin-technical-beta.html - with the regular set of APDUs for standard wallet operations enabled.
Can be tested quickly tested with the Python API at https://github.com/LedgerHQ/btchip-python and Electrum (force noPin = True in getClient in plugins/ledger/ledger.py)
This application is compatible with the Ledger Bitcoin Wallet Chrome Application available on Github at https://github.com/LedgerHQ/blue-app-btc and on Chrome Web Store at https://chrome.google.com/webstore/detail/ledger-wallet-bitcoin/kkdpmhnladdopljabkgpacgpliggeeaf
Using the beta high level communication API (1.1.2+)
The high level communication API provides a set of functions to directly sign transactions in Chrome, Opera or Firefox with the U2F extension with no Chrome app installed.
To use this API, make sure that "Browser Mode" is activated in the Settings of the Nano S application. This setting is not compatible with the former communication API, and needs to be disabled to use the Ledger Wallet Chrome application
Usage
Include the necessary headers (copied from the js/ directory) in your web page
<head>
<script src="thirdparty/q.js"></script>
<script src="thirdparty/async.min.js"></script>
<script src="thirdparty/u2f-api.js"></script>
<script src="dist/ledger-btc.js"></script>
</head>
Create a communication object
var dongle = new LedgerBtc(20);
For each UTXO included in your transaction, create a transaction object from the raw serialized version of the transaction used in this UTXO
var tx1 = dongle.splitTransaction("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");
var tx2 = dongle.splitTransaction("...")
To sign a transaction involving standard (P2PKH) inputs, call createPaymentTransactionNew_async with the folowing parameters
inputsis an array of [ transaction, output_index, optional redeem script, optional sequence ] where- transaction is the previously computed transaction object for this UTXO
- output_index is the output in the transaction used as input for this UTXO (counting from 0)
- redeem script is the optional redeem script to use when consuming a Segregated Witness input
- sequence is the sequence number to use for this input (when using RBF), or non present
associatedKeysetsis an array of BIP 32 paths pointing to the path to the private key used for each UTXOchangePathis an optional BIP 32 path pointing to the path to the public key used to compute the change addressoutputScriptis the hexadecimal serialized outputs of the transaction to signlockTimeis the optional lockTime of the transaction to sign, or default (0)sigHashTypeis the hash type of the transaction to sign, or default (all)
This method returns the signed transaction ready to be broadcast
dongle.createPaymentTransactionNew_async(
[ [tx, 1] ],
["0'/0/0"],
undefined,
"01905f0100000000001976a91472a5d75c8d2d0565b656a5232703b167d50d5a2b88ac").then(
function(result) { console.log(result);}).fail(
function(error) { console.log(error); });
);
To obtain the signature of multisignature (P2SH) inputs, call signP2SHTransaction_async with the folowing parameters
inputsis an array of [ transaction, output_index, redeem script, optional sequence ] where- transaction is the previously computed transaction object for this UTXO
- output_index is the output in the transaction used as input for this UTXO (counting from 0)
- redeem script is the mandatory redeem script associated to the current P2SH input
- sequence is the sequence number to use for this input (when using RBF), or non present
associatedKeysetsis an array of BIP 32 paths pointing to the path to the private key used for each UTXOoutputScriptis the hexadecimal serialized outputs of the transaction to signlockTimeis the optional lockTime of the transaction to sign, or default (0)sigHashTypeis the hash type of the transaction to sign, or default (all)
This method returns the signed transaction ready to be broadcast
