crypto_wallet_util 2.0.3

A collection of utility functions for cryptocurrencies.

Changelog

2.0.3 - 2026-07-17

Fixed

• BTC address generation and validation now consistently honor the selected network, including legacy, SegWit v0, BIP86 Taproot, custom HRPs, and fail-closed handling for explicitly configured networks without a valid HRP.
• Taproot key tweaking now follows BIP341 lift_x semantics and is pinned to the official BIP86 address and scriptPubKey vector.
• Bech32, Bech32m, and CashAddr decoding now verifies checksum, network prefix, witness version and length, and canonical bit padding.
• BCH testnet uses bchtest plus testnet version bytes, and BCH validation requires a full network-matching CashAddr to avoid BTC/BCH legacy ambiguity.
• PSBT change detection infers the CashAddr network prefix from the input address instead of hard-coding bitcoincash, so BCH testnet CashAddr change outputs no longer abort transaction construction.
• PSBT.fromTransferPsbt selects the mainnet or testnet chain config from the extended key's BIP32 version bytes, so a standard testnet tpub (0x043587cf) parses and builds instead of being rejected by the mainnet config and crashing on a null wallet. BTC/BCH testnet BIP32 public version bytes were corrected to 0x043587cf.
• BTC PSBT construction remains backward-compatible with the non-standard testnet extended public-key version (0x04358a68, tpw...) emitted by 2.0.2, while malformed keys and genuinely unknown versions now fail closed.
• Taproot wallets keep the caller's WalletSetting by reference and derive the BIP86 path at sign time, so switching the setting's network stays consistent across existing and freshly derived wallets.

2.0.2 - 2026-07-02

Fixed

• PSBT: parse LTC P2SH / Nested SegWit addresses correctly by plumbing chain-aware version bytes and bech32 HRP through address encoding instead of hard-coding BTC mainnet values.
• GSPL: support LTC P2SH payment address parsing by detecting the script type (P2PKH vs P2SH) and resolving the correct network version bytes from the bip44 path coin-type segment.
• BTC / LTC chain configs: fill in distinct testnet NetworkType values (previously shared mainnet settings).

2.0.1 - 2026-06-12

Added

• SC (Sia): native Go FFI transaction bridge (ScGoFfiBridge) as a faster, opt-in alternative to the WASM bridge. The default create() is unchanged and still uses the WASM bridge (ScWasmRunBridge), so existing callers are unaffected. The native library is not bundled: the caller builds it for their platform (see lib/src/forked_lib/sia-wasi/build.sh), loads it, and passes it via ScTransactionBuilder.createWithFfi(DynamicLibrary).

Changed

• Minimum Dart SDK raised to >=3.11.0 (required by the wasd WASM interpreter that backs the default SC bridge). Consumers on Dart 3.7–3.10 must upgrade.

Removed

• Pruned dead code from the vendored bitcoin_base_hd fork that is never reached by this package (BTC/LTC/BCH only use ECPrivate):
  • the entire provider/ subtree (Electrum/HTTP API providers and the BitcoinTransactionBuilder / BCH builder) and utils/btc_utils.dart (~2.2k lines).
  • ECPublic.verifyTransactionSignature and ECPublic.verifySchnorrTransactionSignature (unused; their post-upgrade bodies had latent argument-shape issues).

2.0.0 - 2026-06-09

BREAKING

• Upgrade blockchain_utils from ^1.4.1 to ^6.0.0. Resolves the dependency conflict reported in #20 (consumers using bitcoin_base 7.x / xrpl_dart 7.x, which require blockchain_utils ^6.0.0).
• Minimum Dart SDK raised to >=3.7.0 (required by blockchain_utils 6.0.0).

Changed

• Migrated the vendored bitcoin_base_hd and xrpl_dart forks to the blockchain_utils 6.x API: relocated utility imports to the package barrel, Tuple/item1,item2 → Dart records ($1,$2), mask*/writeUintXLE → BinaryOps.*, bytesEqual/iterableIsEqual → BytesUtils/CompareUtils, Secp256k1*KeyEcdsa → Secp256k1*Key, BitcoinSigner/BitcoinVerifier → BitcoinKeySigner/BitcoinSignatureVerifier, BigintUtils.orderLen → BigintUtils.bitlengthInBytes.
• ECDSA / Taproot / message signing outputs verified byte-for-byte identical to the pre-upgrade implementation; XRP secp256k1 family-seed derivation and classic/X-address conversion pinned with characterization tests.
• Bech32Validations / SegwitValidations declared as mixin (Dart 3 language level no longer permits using a plain class as a mixin).

Notes

• No public API changes beyond the SDK floor; all 782 unit tests pass.
