Conversation
Implement sync getAddress so setPhrase works, clear scan/LWS/rpc state on phrase change and purge, return unlocked balance from wallet-rpc getBalance, add getWalletBalanceDetail, and refuse transfers that exceed unlocked funds.
📝 WalkthroughWalkthroughThe Monero client now supports synchronous address derivation, phrase and wallet-state management, detailed wallet balances, unlocked-balance reporting, and transfer rejection when funds are not spendable. Tests, README status entries, and a patch changeset describe the updated behavior. ChangesMonero client hardening
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟠 High · up to The wallet reset change can replace an active request queue, allowing overlapping operations to select the wrong wallet and potentially return incorrect balances or perform transfers against the wrong account. The PR should not merge until reset serialization is preserved and the state-clearing behavior is covered by effective regression tests.

Test the wallet-state reset contract.
This test passes if resetWalletState() is removed. super.purgeClient() already clears phrase, so the assertion only verifies inherited phrase clearing.
Seed observable scan-cache and LWS-session state. Verify that both setPhrase with a new phrase and purgeClient clear that state.
As per coding guidelines, “Define verifiable success criteria for each task, write regression tests for fixes or validation changes where applicable, and verify each step of multi-step work.”

Keep the active wallet-RPC queue during a state reset.
resetWalletState() replaces Client.walletRpcLock while withWalletRpcLock() may still be running. A subsequent prepareWalletRpc() can then call ensureWallet() concurrently on the same endpoint. Because ensureWallet() changes the process-wide active wallet, the operations can execute balance or transfer calls against the wrong wallet. Keep the existing queue or serialize the reset behind it, and add an interleaving regression test.
