6.1.0

added

  • taproot support for payments (p2tr) and PSBT. See taproot.spec.ts integration test for examples. (#1742)

6.0.2

fixed

  • p2sh payment now uses empty Buffer for redeem.output when redeemScript is OP_FALSE (#1802)
  • Fix ripemd160 hashing fallback issue (#1812)

6.0.1

  • No changes to public API

6.0.0

removed

  • bip32: Removed the re-export. Please add as dependency to your app instead.
  • ECPair: Please use bip32 moving forward. ecpair package was created for those who need it.
  • TransactionBuilder: Any internal files used only in TB (classify, templates, etc.) were also removed.

added

  • taproot segwit v1 address support (bech32m) via address module (#1676)
  • hashForWitnessV1 method on Transaction class (#1745)

fixed

  • Transaction version read/write differed. (#1717)

5.2.0

changed

  • Updated PSBT to allow for witnessUtxo and nonWitnessUtxo simultaneously (Re: segwit psbt bug) (#1563)

added

  • PSBT methods getInputType, inputHasPubkey, inputHasHDKey, outputHasPubkey, outputHasHDKey (#1563)

5.1.10

fixed

  • Fixed psbt.signInputAsync (and consequentially all Async signing methods) not handling rejection of keypair.sign properly (#1582)

5.1.9

fixed

  • Fixed errors for psbt.txOutputs getter (#1578)

5.1.8

fixed

  • Throw errors when p2wsh or p2wpkh contain uncompressed pubkeys (#1573)

added

  • Add txInputs and txOutputs for Psbt (#1561)

changed

  • (Not exposed) Added BufferWriter to help ease maintenance of certain forks of this library (#1533)

5.1.7

fixed

  • Fixed Transaction class Output interface typing for TypeScript (#1506)
  • Add weight() to Block class, add optional includeWitness arg to Transaction byteLength method (#1515)
  • Match the old TransactionBuilder behavior of allowing for multiple instances of the same pubkey to be in a p2ms script for PSBT (#1519)

added

  • Allow the API consumer to pass in the finalizer functions to allow for any type of transaction to be finalized. It places the most crucial part of transaction construction on the consumer, and should be used with caution. (#1491)

5.1.6

fixed

  • PsbtOutputExtended did not support using the address attribute properly. It is now fixed.

5.1.5

added

  • Psbt now has getFee(): number for use when all inputs are finalized. It returns the satoshi fee of the transaction. Calling getFee, getFeeRate, or extractTransaction will cache these values so if you call one after the other, the second call will return immediately.

5.1.4

changed

  • Psbt inputs using segwit scripts can now work with nonWitnessUtxo as well as the original witnessUtxo. The reasoning for this is that nonWitnessUtxo has all the information contained in the witnessUtxo, so rejecting signing even though we have all the info we need is unnecessary. Trying to sign a non-segwit script with a witnessUtxo will still throw an Error as it should.

5.1.3

changed

  • TypeScript types: Made Signer and SignerAsync use any for network since we only check for equivalence. (#1448)
  • TypeScript types: Made the args for addInput and addOutput for Psbt actually accept updateInput and updateOutput parameters. (#1449)

5.1.2

added

  • ECPair and bip32 objects now have a lowR boolean attribute defaulted to false. You may set it to true to ensure that the sign method uses low R values (#1442) (This is to enable low R usage in Psbt, since we decided not to give the low R flag to the Psbt class, since it makes more sense to be an attribute of the Signer interface)

5.1.1

changed

  • Name inconsistencies for Psbt class. (Quick fix)

5.1.0

added

  • A new Psbt class for creating, distributing, combining, signing, and compiling Transactions (#1425)
  • A name attribute to the Payment interface. P2SH and P2WSH are nested with '-' as separator, and p2ms is in the format of 'p2ms(m of n)'' all others are just hard coded. (#1433)

changed

  • TransactionBuilder: Migrate to stricter type checks during sign by switching to a single object parameter (#1416)
  • tests: Use regtest-client as separate library (#1421)

5.0.5

added

  • Added ECPairInterface Stack and StackElement interfaces to the main index.ts export (TypeScript only affected)

5.0.4

  • low R value support for ECPair, bip32, and TransactionBuilder (default off) via txb.setLowR() (#1385)

fixed

added

  • TypeScript support (#1319)
  • Block.prototype.checkTxRoots will check the merkleRoot and witnessCommit if it exists against the transactions array. (e52abec) (0426c66)

changed

  • Block.calculateMerkleRoot now has forWitness?: boolean which when true returns the witness commit (a652d04)

removed

  • Block.prototype.checkMerkleRoot was removed, please use checkTxRoots (0426c66)

4.0.5

fixed

  • Fixed bug where Angular apps break due to lack of crypto at build time. Reverted #1373 and added (6bead5d).

4.0.4

fixed

  • Fixed bug where Electron v4 breaks due to lack of 'rmd160' alias for ripemd160 hash. (#1373)

4.0.3

fixed

  • Fixed TransactionBuilder to require that the Transaction has outputs before signing (#1151)
  • Fixed payments.p2sh, which now takes the network from the redeem attribute if one is not given in the object argument (#1232)
  • Fixed Block.calculateTarget to allow for exponents up to 29 (#1285)
  • Fixed some low priority rarely occurring bugs with multisig payments and TransactionBuilder multisig processing (#1307)

added

  • Regtest network object to networks (#1261)

4.0.2

fixed

  • Fixed TransactionBuilder not throwing when payment type validation should fail (#1195)

removed

  • Removed rogue package.json from src/payments (#1216)

changed

  • ECPair.prototype.sign now returns a 64-byte signature Buffer, not an ECSignature object (#1084)
  • ECPair (and all ECDSA code) now uses tiny-secp256k1, which uses the libsecp256k1 library (#1070)
  • TransactionBuilder internal variables are now __ prefixed to discourage public usage (#1038)
  • TransactionBuilder now defaults to version 2 transaction versions (#1036)
  • script.decompile now returns [Buffer] or null, if decompilation failed (#1039)

fixed

  • Fixed TransactionBuilder rejecting uncompressed public keys to comply with BIP143 (#987)

2.1.0

From this release users should use the HDNode directly (compared to accessing .keyPair) when performing ECDSA operations such as sign or verify. Ideally you shoud not have to directly access HDNode internals for general usage, as it can often be confusing and error prone.

added

  • ECPair.prototype.getNetwork
  • HDNode.prototype.getNetwork, wraps the underyling keyPair's getNetwork method
  • HDNode.prototype.getPublicKeyBuffer, wraps the underyling keyPair's getPublicKeyBuffer method
  • HDNode.prototype.sign, wraps the underlying keyPair's sign method
  • HDNode.prototype.verify, wraps the underlying keyPair's verify method

2.0.0

In this release we have strived to simplify the API, using native types wherevever possible to encourage cross-compatibility with other open source community modules.

The ecdsa module has been removed in lieu of using a new ECDSA module (for performance and safety reasons) during the 2.x.y major release. Several other cumbersome modules have been removed, with their new independent modules recommended for usage instead for greater modularity in your projects.

Backward incompatible changes:

added

  • export address, for address based utility functions, most compatible, just without Address instantiation, see #401, #444
  • export script, for script based utility functions, mostly compatible, just without Script instantiation, see #438, #444
  • export ECPair, a merged replacement for ECKey/ECPubKey, invalid types will throw via typeforce

changed

  • address.toOutputScript, ECPair.prototype.fromWIF and HDNode.prototype.fromBase58 no longer automatically detect the network, networks.bitcoin is always assumed unless given.

  • assert was used for type checking, now replaced by typeforce

  • BIP66 compliant strict DER signature validation was added to ECSignature.fromDER, changing the exact exception messages slightly, see #448.

  • new HDNode(d/Q, chainCode, network) -> new HDNode(keyPair, chainCode), now uses ECPair

  • HDNode.prototype.toBase58(false) -> HDNode.prototype.neutered().toBase58() for exporting an extended public key

  • HDNode.prototype.toBase58(true) -> HDNode.prototype.toBase58() for exporting an extended private key

  • Transaction.prototype.hashForSignature(prevOutScript, inIndex, hashType) -> Transaction.prototype.hashForSignature(inIndex, prevOutScript, hashType)

  • Transaction.prototype.addInput(hash, ...): hash could be a string, Transaction or Buffer -> hash can now only be a Buffer.

  • Transaction.prototype.addOutput(scriptPubKey, ...): scriptPubKey could be a string, Address or a Buffer -> scriptPubKey can now only be a Buffer.

  • TransactionBuilder API unchanged.

removed

  • export Address, strings are now used, benchwith no performance loss for most use cases

  • export base58check, use bs58check instead

  • export ecdsa, use ecurve instead

  • export ECKey, use new export ECPair instead

  • Transaction.prototype.validateInput, use Transaction.prototype.hashForSignature and ECPair.verify

  • HDNode.fromBuffer, use HDNode.fromBase58 instead

  • HDNode.fromHex, use HDNode.fromBase58 instead

  • HDNode.toBuffer, use HDNode.prototype.toBase58 instead

  • HDNode.toHex, use HDNode.prototype.toBase58 instead

  • networks.*.magic, see the comment here

  • networks.[viacoin|viacointestnet|gamerscoin|jumbucks|zetacoin], import these yourself (see #383/a0e6ee7)
