libwallet 0.3.5

Dart client for libwallet — a multi-chain cryptocurrency wallet library with TSS (Threshold Signature Scheme) key management. Supports EVM chains, Bitcoin, and Solana via direct FFI to the Go library.

0.3.5

• Direct account signing: new Account.signMessage, signTransaction, signAndSendTransaction endpoints let wallet-host apps sign directly without routing through the Web3 pending-request/approve flow. Removes ~80 lines of async listener code from the typical Dart integration.
• View accounts (read-only): accounts.createView(type:, address:, xpub:) creates accounts with no backing wallet — suitable for watching a counterparty address or an HD tree (xpub, bitcoin-family). Balance and NFT queries work; signing is rejected. New Account.isViewOnly getter.
• Progress redesign: progress events are now a single 0..1 fraction instead of {count, running}. ECDSA wallet creation now emits fine- grained ticks during Paillier / NTilde safe-prime generation (one per prime found out of 4, per key) — previously the UI was blind for 20+ seconds per key share. Requires tss-lib v2.2.4+.
• Typed-API cleanup: removed dynamic returns and raw Map<String, dynamic> param inputs across the API surface. New typed models: SignedMessage, RemoteKeySession, RemoteKeyValidation, NftListing, WalletBackupEntry, RpcTestResult, UnsignedTransaction. Methods like transactions.signAndSend(UnsignedTransaction), wallets.backup(), remoteKeys.validate() now return proper model instances. Raw param maps on contacts.update, networks.update, tokens.update replaced with named parameters.
• Validation: reject wallet Curve values outside {secp256k1, ed25519}; reject account type/curve mismatches (e.g. solana on secp256k1, ethereum on ed25519). Bitcoin accounts now derive on BIP-44 coin_type 0 (m/44/0/0/i) instead of Ethereum's coin_type 60.

0.3.4

• Email 2FA: RemoteKey:new (and remoteKeys.create) now accept an email address in addition to phone numbers. Pass either number or email — the EllipX backend routes SMS vs email verification based on whether the value contains @.

0.3.3

• Bitcoin balance fix: modchain_assets returns balance as a decimal-formatted number ("0.00000000"), not int64. Decode via outscript.BtcAmount which handles both forms. Previously failed with: json: cannot unmarshal number 0.00000000 into Go struct field.
• Solana NFT fix: getAssetsByOwner (Helius DAS API) requires named JSON-RPC params, not positional. New Network.DoRPCNamed() helper. Previously failed with: invalid type: map, expected a string.
• Bitcoin UTXO decode: modchain_lookupTxoBIP32 response uses the same BtcAmount serialization for amt and balance fields. Type switched from int64 to outscript.BtcAmount across wlttx/bitcoin.go.
• EVM NFT lookup hardening: type assertions on the modchain_assets response in wltnet/nft.go could panic if any field was missing or the wrong type. Replaced with comma-ok form.
• iOS Dart Tests CI timeout bumped 45 → 60 minutes (Xcode build slow).

0.3.2

• iOS simulator support: build hook now detects iphoneos vs iphonesimulator SDK and downloads the correct binary. Previously the simulator would try to link the device-only binary and fail.
• Release now includes liblibwallet-iossimulator-arm64.a (Apple Silicon) and liblibwallet-iossimulator-x64.a (Intel Mac simulators) alongside the existing liblibwallet-ios-arm64.a device binary.

0.3.1

• Bitcoin HD address support: bitcoin-type accounts now derive multi-address HD trees under their account xpub. Balance queries call modchain_assets(xpub) which scans 0..lastI+20 child keys (BIP-44 style gap limit) server-side.
• New AccountApi.xpub(id): returns the BIP-32 extended public key.
• New AccountApi.nextAddress(id): returns the next clean receive (or change) address based on on-chain scan.
• New AccountApi.allAddresses(id): lists all HD addresses across receive and change chains with activity markers.
• Account.Address now points to m/0/0 (first receive address) instead of m/0 for Bitcoin-family accounts. BTC/LTC/DOGE/BCH supported.

0.3.0

• EIP-1559 transactions: Auto-selected when the chain supports it. New maxFeePerGas and maxPriorityFeePerGas fields on Transaction.
• ERC-20 transfers: New erc20_transfer transaction type. Pass a token XUID in Asset, recipient in To, and amount — libwallet encodes the transfer(address,uint256) call automatically.
• ENS / SNS name resolution: New client.names.resolve('vitalik.eth') API. Auto-detects .eth (Ethereum) and .sol (Solana) suffixes.
• Solana devnet: Routes to the correct Helius devnet RPC endpoint when using a Solana network with chainId: "devnet".
• Local dev: hook/build.dart now prefers a local testserver/liblibwallet.<ext> over downloading from GitHub Releases.
• Fix: macOS dylibs built with -headerpad_max_install_names so Dart can bundle them without relinking.

0.2.0

• Auto-download native binaries from GitHub Releases at build time
• CI testing on macOS, Android emulator, and iOS simulator
• 43 integration tests covering all API endpoints
• Full dartdoc on all model fields (~130 fields)
• Comprehensive README with usage examples

• 17 typed API classes covering all libwallet endpoints
• 15 model classes with full dartdoc
• Socket transport as legacy fallback
• Native asset hook for pub.dev binary distribution
