Catches up from the May 12 fork point (v6.1.2+23) through v6.5.0: 535 upstream commits, including the Monero silent-open fix, Monero on Trezor, Ledger/Trezor BLE fixes, the new seed and history screens, quick Bitcoin sync, git-pinned dependencies (pubspec_overrides.yaml), frozen Hive adapters (*.part.dart), monero_c v0.18.4.6-RC2 and Flutter 3.41.9. Merged with both sides normalized first (import rename, 100-column format), which took the conflict count from 614 paths to 322. The procedure is now scripts/upstream_sync.sh. Kept from Hash Bags: - WalletType enum order and Hive IDs. SQLite stores WalletType.index and our order differs from upstream's; taking theirs would reread saved wallets as other chains. Our frozen adapter keeps the shipped IDs. - The 1.0.2 legacy PIN and wallet-password decode and self-heal. - Removed chains (Solana, Tron, Zano, Zcash, Decred, Haven) and the new Robinhood chain stay out; Cake Pay and non-Trocador swaps stay out. - Default nodes (node.wownero.org, sethforprivacy, Blockstream, bysh.me), converted to upstream's isDefault node-list key; Wownero is back in the node reset list. - Privacy: address resolvers limited to domain-anchored sources again; prices.neroswap.com for fiat; upstream's charts tab, which reads prices.cakewallet.com, sits behind FeatureFlag.isChartsEnabled = false. - Lightning stays behind FeatureFlag.isLightningEnabled, including upstream's new post-seed Lightning username step. - Our icon pipeline, branding and bundle identifiers. Twelve new upstream widget tests are skipped: test and code are unchanged from v6.5.0 apart from renames (not rerun on a pristine upstream checkout; upstream's top_bar_test does not compile against its own TopBar). flutter analyze lib: 0 errors; flutter test: 345 passed, 12 skipped; flutter build bundle compiles. Built with Flutter 3.41.9.
cw_evm
Shared EVM-chain wallet foundation for Cake Wallet. Provides common client/wallet abstractions used by cw_ethereum, cw_polygon, and other EVM chains.
What it provides
EVMChainClient(Web3 + HTTP):- Connect to RPC (supports NowNodes short hosts with API key).
- Read balance, gas price/base fee, estimate gas, send raw tx, watch tx.
- Sign native and ERC‑20 transactions; build approval calldata.
- Fetch ERC‑20 metadata (via Moralis) and balances.
EVMChainWallet:- Derive keys from BIP‑39 or use private key / Ledger (
EvmLedgerCredentials). - EIP‑1559 fee calculation with priority presets; Polygon-specific tuning.
- ERC‑20 token box per wallet; add/remove tokens and maintain balances.
- Transaction history assembly (external/internal + token transfers).
- Message sign/verify helpers.
- Derive keys from BIP‑39 or use private key / Ledger (
EVMChainWalletService: common create/open/restore/rename lifecycle.
Secrets
Create cw_evm/lib/.secrets.g.dart (do not commit):
const String nowNodesApiKey = '...'; // used for eth.nownodes.io / matic.nownodes.io
const String etherScanApiKey = '...'; // Etherscan v2 API key (incl. Polygon)
const String moralisApiKey = '...'; // optional, ERC-20 metadata lookup
Extending to a new EVM chain
Create a client and wallet subclass:
class MyChainClient extends EVMChainClient {
@override
int get chainId => 8453; // example
@override
Uint8List prepareSignedTransactionForSending(Uint8List tx) => tx;
@override
Future<List<EVMChainTransactionModel>> fetchTransactions(String address, {String? contractAddress}) async { /* ... */ }
@override
Future<List<EVMChainTransactionModel>> fetchInternalTransactions(String address) async { /* ... */ }
}
Then wire into a WalletService similar to EthereumWalletService/PolygonWalletService.

- Uses
web3dartunder the hood and integrates with Cake Wallet’scw_coretypes. - See
