libwallet 0.3.10

Multi-chain TSS cryptocurrency wallet client. Supports EVM, Bitcoin, Solana and Monacoin via direct FFI to the Go libwallet core.

0.3.10

• Solana ed25519 self-heal now actually runs (follow-up to 0.3.9): the self-heal path in 0.3.9 had a wrong type assertion against the signing context — it silently never triggered, so affected wallets kept failing every send attempt. Fixed to use wltintf.GetEnv(ctx). Additionally, added a pre-flight repair step in the Solana send path that decrypts one key share BEFORE building the transaction and patches acct.Pubkey in-memory, so the first send on an upgraded install succeeds instead of needing a failed-then-retry cycle. New exported helper wltwallet.EnsureEd25519Pubkey is a no-op when the wallet is already correct.

0.3.9

• Solana ed25519 pubkey fix (breaking for existing Solana wallets): ed25519 wallets created pre-0.3.9 stored the X coordinate of the Edwards point (big-endian) as the "public key" instead of the standard compressed encoding (Y little-endian with X's sign bit in the MSB of byte 31). Consequences: the displayed Solana address was wrong, balance queries hit a different address from the one the TSS signs with, and every sendTransaction failed with "Transaction did not pass signature verification". Fixed at wallet creation via ToEd25519PubKey().Serialize(). Existing broken wallets self-heal on the first sign attempt (which fails once, then the repair propagates to the wallet + linked accounts and the retry succeeds).
• On-chain tx history backfill (EVM): client.transactions.list() now includes on-chain activity, not just txs this install built. Triggered in the background on Account:setCurrent / Network:setCurrent / env init. First tries modchain_historyByAddress, falls back to Otterscan's ots_searchTransactionsAfter (erigon v3). New client.txHistoryUpdates stream fires when new rows land.
• Immediate balance refresh after sends: every Transaction: signAndSend / Account:signAndSendTransaction / mpurse_sendRawTransaction / solana_sign_send_transaction now nudges the background balance poller. Users see the new balance within ~1 s instead of up to 60 s.

0.3.8

• Background balance polling: new client.balanceChanges stream yields a BalancesChangedEvent (full {network, account, assets} snapshot) every 60 s when the current account / network balances change. Lifecycle-aware — pauses under Lifecycle:update('background') / paused, resumes with an immediate poll on foreground / resumed / active.
• RPC timeouts (reliability fix): all Network.DoRPC / DoRPCNamed calls are now bounded by a 30 s default deadline. A misbehaving upstream (dead Ethereum public RPC, stale Solana endpoint, etc.) can no longer wedge a goroutine forever. The balance poller uses a tighter 15 s cap. Callers that need a specific deadline can use the existing DoRPCCtx / DoRPCNamedCtx. Fixes an iOS CI hang.
• Network:testRPC extended: now accepts type = evm / solana / bitcoin and probes the right health method per family. EVM is still the default; RpcTestResult gained solanaVersion / solanaCluster / bitcoinChain / bitcoinBlocks fields + isEvm / isSolana / isBitcoin getters.
• Android 16 KB page alignment: CI now builds every Android .so (both the AAR and the Dart FFI set) with -Wl,-z,max-page-size=16384 and verifies it with readelf. Required for Android 15+ devices with 16 KB page size (Pixel 8+).

0.3.7

• Wallet-identity plumbing: new client.info.setWalletInfo(clientId:, name?, version?) registers the host wallet with libwallet. The clientId is sent as the Sec-ClientId HTTP header on every Crypto/WalletSign:* call, which the WalletSign backend uses to pick branded SMS / email copy, apply per-app rate limits, and tag audit logs. name / version are stored for future use (untrusted display strings, diagnostics). Called once at startup; backward- compatible (header not sent if not configured).
• EIP-6963 UUID fix: webview injection docs corrected — generate a fresh UUIDv4 per page load (spec requirement), do NOT persist across launches. rdns is the stable identifier dApps key off, not uuid.
• Drop Unix-socket transport fallback: FFI is the only supported transport now. Removed LibwalletClient.connect(socketPath) / .fromSocket(socket), JsonRpcConnection, request framing helper, and the socket-based testserver binary. Transport interface stays (test mocks still work) but has one implementation.

0.3.6

• WalletConnect v2: full wallet-side implementation. client.walletConnect covers pair / sessions / approveSession / rejectSession / respond / respondError / emitEvent / disconnect. Two sugar streams (walletConnectProposals, walletConnectRequests) deliver typed WcSessionProposal / WcSessionRequest objects. Sessions persist across restarts (SQL-backed); relay reconnects with backoff. Protocol pieces implemented: X25519 + HKDF + ChaCha20-Poly1305 envelopes, Ed25519 relay JWT auth, CAIP-10/-2 namespace handling, wc_sessionPropose / Settle / Request / Event / Delete. See doc/walletconnect_integration.md.
• Transaction simulation + decoding: new client.transactions.simulate. On EVM (erigon v3 backend), uses debug_traceCall with the callTracer to walk the full call frame tree and return every ERC-20 Transfer + Approval and every value-carrying CALL at any depth as TransactionSimulation.effects. Second pass with prestateTracer (diff mode) returns per-address native-balance deltas as balanceChanges. Top-level calldata decoded into decodedMethod + decodedArgs (native_transfer / erc20_transfer / erc20_approve / unknown). Revert reasons decoded from standard Error(string) ABI. Solana wraps simulateTransaction (logs + unitsConsumed + err). Bitcoin parses via outscript.BtcTx (inputs + outputs + fee).
• WebView injection: new client.web3.injectionScript(...) generates a JS blob exposing libwallet as window.ethereum (EIP-1193 + EIP-6963), window.solana (Wallet Standard), and window.mpurse (Monacoin — github.com/tadajam/mpurse). Full wiring walkthrough in doc/webview_integration.md.
• Bitcoin-family message signing (via mpurse): mpurse_signMessage signs with the TSS key over the standard "\x18Bitcoin Signed Message:\n" / "\x19Monacoin Signed Message:\n" / etc. prefix, returning the 65-byte compact signature (base64, Bitcoin Core signmessage format). mpurse_signRawTransaction parses the hex, matches inputs to the user's xpub via modchain_lookupTxoBIP32, signs each input, and returns the signed hex. mpurse_sendRawTransaction is a direct passthrough to sendrawtransaction. mpurse_sendAsset still errors (Counterparty server interaction is out of scope).
• Monacoin network support: bitcoinAddress recognizes monacoin chain id and emits the bech32 mona1... address via outscript.Out.Address("monacoin").
• Typed pending-request flow: PendingRequest is now sealed with one subtype per Web3 request kind (ConnectRequest, PersonalSignRequest, SignTypedDataRequest, SolanaSign* / Mpurse* / …, UnknownPendingRequest). The request event now carries the full request object so consumers can render the prompt on first paint without a follow-up Request/<id> fetch. New client.pendingRequests stream yields fully-parsed requests ready for pattern matching.
• Example package layout: new example/libwallet_example.dart CLI sample covering init / wallet create with live progress / account / balance / pendingRequests subscription. Satisfies pub.dev's example requirement.
• pubspec: description trimmed to 129 chars (was 212) to satisfy pub.dev's metadata scan.

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)
