# Contributing to Hash Wallet
Thanks for the interest. Before opening a PR, please read this.
## Project shape
Hash Wallet is a **friendly fork** of [Cake Wallet](https://github.com/cake-tech/cake_wallet). We periodically merge upstream changes and try to keep our divergence narrow. Every change you propose should be evaluated through that lens: will this make future upstream syncs harder, and if so, is the value worth the cost?
## Branch model
- `dev` is the integration branch — open PRs against `dev`.
- `main` is reserved for tagged releases.
- We do not use long-lived feature branches. Iterate on `dev` directly via small focused PRs.
## Build environment
See the build section of [`README.md`](README.md). Flutter version is pinned (`.tool-versions` + `Dockerfile`). Don't use a newer Flutter SDK — Cake's `hive_generator` / `build_resolvers` deps fail on Dart 3.10+ because the `_macros` pseudo-package was removed.
If you use `mise` or `asdf`, the right Flutter version will activate automatically.
## Generated code
Several layers use code generation (MobX stores, Hive type adapters, JSON serializers, configure.dart-generated wallet entry points). Regenerate with:
```bash
dart pub run build_runner build --delete-conflicting-outputs
```
For the wallet-types and pubspec generation:
```bash
dart run tool/configure.dart --monero --wownero --bitcoin --bitcoinCash \
--ethereum --polygon --base --arbitrum --bsc --nano --dogecoin
```
(That's the canonical Hash Wallet build flag set. Don't pass `--solana`, `--tron`, `--zano`, `--decred`, or `--zcash` — those packages were deleted.)
## Code style
- Match the surrounding style. We have not introduced new lints beyond Cake's.
- New observable state goes through MobX; persisted state through Hive.
- Don't add new top-level analytics. Hash Wallet ships with no telemetry by design.
- Don't import `package:cw_zano/`, `package:cw_tron/`, `package:cw_solana/`, `package:cw_decred/` — those packages are deleted. The corresponding `WalletType.*` enum values still exist in `cw_core/lib/wallet_type.dart` for backwards-compat but are never instantiated.
- Avoid adding `cake_*`-prefixed file or symbol names in new code. Use `hash_wallet`-prefixed where the symbol is ours, and leave Cake-prefixed names alone where they're inherited (so upstream merges still apply cleanly).
## What we generally won't accept
- Re-enabling Solana, Tron, Zano, Decred, or Zcash. The fork exists in part to drop these — opening that door defeats the purpose.
- New buy/sell provider integrations that require routing through Cake's `exchange-helper.cakewallet.com` proxy. Direct provider APIs are fine if we can register Hash Wallet / Such Software LLC as the partner.
- Lightning Network integration. Greenlight (and self-hosted alternatives) require running infrastructure we're not in a position to operate yet.
- Cake Pay re-enable. The infrastructure is Cake Labs's; we can't run it.
- New defaults that point at `cakewallet.com` hosts. We're moving away from depending on Cake's infrastructure — community nodes, our own proxies (`exchange-helper.such.software`, `prices.neroswap.com`), or both, are preferred.
- Anything that adds telemetry, push notifications via third-party SDKs, or remote bulletin services that the user can't audit.
## What we want
- Wownero polish (every paper cut counts — it's the reason this fork exists).
- Build reproducibility improvements (especially Docker / CI parity).
- Privacy-leaning defaults (own-node guidance, Tor/I2P integration improvements, fewer outbound calls).
- Wallet-core bug fixes — these we will happily upstream to Cake.
- Documentation, especially around the build pipeline and the Cake → Hash Wallet diff.
## Reporting bugs
Open an issue at https://github.com/Such-Software/hash-wallet/issues. Please include:
- Build artifact ID (the CI workflow names the artifact by commit SHA).
- Platform + OS version.
- Terminal output if you built and ran from a terminal — many error popups don't print to stderr; check `<appDir>/error.txt` (typically `~/.config/hash_wallet/error.txt` on Linux).
- Whether the bug also reproduces in the latest Cake Wallet build (so we know whether it's a Cake-upstream bug or a Hash Wallet regression).
## Security disclosures
See [`docs/SECURITY.md`](docs/SECURITY.md). Email `support@such.software` for anything sensitive; do not open a public issue for unpatched vulnerabilities.
## License
By contributing, you agree your contribution is licensed under the [MIT License](LICENSE.md), the same as the rest of Hash Wallet.

# cw_decred
Decred wallet module that bridges to the native `libdcrwallet` via FFI. Provides high‑level methods to create/load wallets, sync, query balances/transactions, build and broadcast transactions, and sign/verify messages.
## Features
- FFI bindings to `libdcrwallet` with an isolate‑based request/response model.
- Initialize, create, load, close wallets; watch‑only creation.
- Start sync with optional peer list; query sync status and best block.
- Query balances, list transactions and unspents, rescan from height.
- Create signed transactions and broadcast raw transactions.
- Export wallet seed; change wallet password.
- Address management (new external address, default pubkey, address lists).
- Message signing and verification.
## Getting started
Ensure the platform library is available:
- Android/Linux: `libdcrwallet.so`
- Apple: embedded `cw_decred.framework/cw_decred`
Initialize and load a wallet:
```dart
final lib = await Libwallet.spawn();
await lib.initLibdcrwallet('', 'info');
await lib.loadWallet(jsonEncode({ /* libdcrwallet config */ }));
await lib.startSync('wallet.db', '');
final status = await lib.syncStatus('wallet.db');
```
## Usage
Create, sign, and broadcast a transaction:
```dart
final signed = await lib.createSignedTransaction('wallet.db', jsonEncode({
// inputs/outputs and policy for libdcrwallet
}));
final txid = await lib.sendRawTransaction('wallet.db', signed);
```
## Additional information
- See `lib/api/` for the isolate wrapper (`libdcrwallet.dart`) and low‑level bindings.
- Errors are surfaced via the `PayloadResult` struct; some calls support `throwOnError` in higher‑level wrappers.

## cw_solana
Solana wallet module for Cake Wallet. Provides native SOL and SPL token support built on `on_chain/solana` with high-throughput RPC usage and safe transaction parsing.
### Features
- Connect to Solana RPC (Ankr/Chainstack/custom) via `SolanaRPC` over HTTP.
- Fetch SOL balances and aggregate SPL token balances across accounts.
- Parse and stream native and SPL token transactions (filters ATA-only and spam-like micro txs).
- Estimate fees per compiled message and enforce rent-exemption checks.
- Create/sign/broadcast SOL and SPL transfers; auto-create recipient ATA when necessary.
- Manage SPL tokens; fetch on-chain metadata (symbol/name) for unknown mints.
- Sign and verify messages.
- Node health checks for SOL and a known SPL token (USDC).
### Getting started
If you use hosted RPC providers, add a secrets file for keys (optional unless using those hosts):
```dart
// cw_solana/lib/.secrets.g.dart (DO NOT COMMIT)
const String ankrApiKey = 'YOUR_ANKR_KEY';
const String chainStackApiKey = 'YOUR_CHAINSTACK_KEY';
```
Connect and sync:
```dart
final service = SolanaWalletService(walletInfoBox, true);
final wallet = await service.create(SolanaNewWalletCredentials(name: 'My SOL', password: 'secret'));
await wallet.connectToNode(node: Node(uriRaw: 'api.mainnet-beta.solana.com', isSSL: true));
await wallet.startSync();
final sol = wallet.balance[CryptoCurrency.sol]?.balance;
```
### Usage
Send SOL:
```dart
final pending = await wallet.createTransaction(
SolanaTransactionCredentials.single(
address: 'SoL...',
cryptoAmount: '0.05',
currency: CryptoCurrency.sol,
),
);
final sig = await pending.commit();
```
Add an SPL token by mint:
```dart
final token = await wallet.getSPLToken('EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v'); // USDC
if (token != null) {
await wallet.addSPLToken(token);
}
```
### Additional information
- When using `rpc.ankr.com` or `solana-mainnet.core.chainstack.com`, the client reads API keys from `.secrets.g.dart`.
- See `lib/` for APIs: `SolanaWalletClient`, `SolanaWallet`, `SolanaWalletService`, and credential types.

## cw_tron
TRON wallet module for Cake Wallet. Implements TRX and TRC-20 token support on top of `on_chain` (Tron), with transaction history and fee estimation via TronGrid.
### Features
- Connect to TRON nodes over HTTP(S) via `TronProvider`/`TronHTTPProvider`.
- Fetch TRX balance and TRC-20 token balances.
- Estimate fees using bandwidth/energy and memo fee; accounts for available account resources.
- Create and sign TRX and TRC-20 transfers (supports send-all and optional memo).
- Broadcast signed transactions.
- Load account history (TRX and TRC-20), filtering spam and TRC10-only events.
- Manage TRC-20 tokens: add/remove tokens and fetch token metadata.
- Sign/verify messages.
- Node health checks for both native and token balance endpoints.
### Getting started
Provide a TRON RPC endpoint and a TronGrid API key. Add a secrets file:
```dart
// cw_tron/lib/.secrets.g.dart (DO NOT COMMIT)
const String tronGridApiKey = 'YOUR_TRONGRID_API_KEY';
```
Basic connect and sync:
```dart
final service = TronWalletService(walletInfoBox, client: TronClient(), isDirect: true);
final wallet = await service.create(TronNewWalletCredentials(name: 'My TRON', password: 'secret'));
await wallet.connectToNode(node: Node(uriRaw: 'api.trongrid.io', isSSL: true));
await wallet.startSync();
final trxBalance = wallet.balance[CryptoCurrency.trx];
```
### Usage
Send TRX:
```dart
final pending = await wallet.createTransaction(
TronTransactionCredentials.single(
address: 'T...',
cryptoAmount: '1.5',
currency: CryptoCurrency.trx,
),
);
final txHash = await pending.commit();
```
Add USDT (TRC-20):
```dart
final usdt = await wallet.getTronToken('TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t');
if (usdt != null) {
await wallet.addTronToken(usdt);
}
```
### Additional information
- History and token queries use TronGrid; set `tronGridApiKey`.
- See `lib/` for APIs: `TronClient`, `TronWallet`, `TronWalletService`, and credential types.

# cw_zano
Zano wallet module for Cake Wallet. Provides a Dart wrapper around the Zano wallet API with typed models and transaction helpers.
## Features
- Wallet lifecycle and status queries via `ZanoWalletApi`.
- Typed models for balances, transfers, recent history, and wallet info.
- Build and submit transfers; pending transaction modeling.
- Address and asset utilities, formatter helpers.
## Usage
See `lib/zano_wallet_api.dart` and `lib/zano_wallet.dart` for the high-level API. Typical flow:
```dart
final api = ZanoWalletApi();
final info = await api.getWalletInfo();
final balance = await api.getBalance();
// create transfer params and broadcast
```
Consult `lib/api/model/` for full set of supported request/response models.
