feat: revamp mnemonic and key file logic #123
Conversation
WalkthroughThe changes refactor key file generation and management across multiple components. The previous dedicated key file generator is removed, and its functionality is incorporated into configuration and initialization flows. Pointers are now used for key files with a new package offering a structured JSON-based key management approach. Simultaneously, constants and configuration paths have been updated, and the clipboard functionality alongside clickable UI elements for mnemonic display have been removed. Minor adjustments are also made in balance initialization and bot mapping. Changes

2873-2876: Enhance path security for sensitive files.While the file permissions are correctly set to 0600, consider adding path validation to prevent directory traversal attacks.
Add path validation before writing sensitive files:
+func isValidPath(path string) error { + if strings.Contains(path, "..") { + return fmt.Errorf("path contains invalid sequences") + } + clean := filepath.Clean(path) + if !strings.HasPrefix(clean, filepath.Clean(userHome)) { + return fmt.Errorf("path escapes user home directory") + } + return nil +} configFilePath = filepath.Join(userHome, common.WeaveDataDirectory, LaunchConfigFilename) +if err = isValidPath(configFilePath); err != nil { + return ui.NonRetryableErrorLoading{Err: fmt.Errorf("invalid config file path: %v", err)} +} if err = os.WriteFile(configFilePath, configBz, 0600); err != nil { return ui.NonRetryableErrorLoading{Err: fmt.Errorf("failed to write config file: %v", err)} }

models/opinit_bots/setup.go (2)
505-506: Minor user-facing message improvement.
The continuity of the message is fine. You might optionally explain how to retrieve the mnemonic from the key file to reduce user confusion.
1408-1409: Concise user prompt.
Appending “Press enter to go next step” is helpful. Consider clarifying the next step’s name for even better guidance.io/keyfile.go (1)
9-14: Add documentation for the KeyFile type and constructor.Consider adding documentation to explain the purpose and usage of the KeyFile type and its constructor. This will help other developers understand how to use this package effectively.
Add this documentation:
+// KeyFile represents a JSON-based key-value store for managing mnemonics. type KeyFile map[string]string +// NewKeyFile creates and returns a new empty KeyFile instance. func NewKeyFile() *KeyFile {models/opinit_bots/config.go (1)
62-102: Consider improving error handling.The function returns an empty key file pointer on error, which could lead to nil pointer dereferences if not handled properly by callers. Consider returning
nilinstead to make error cases more explicit.Apply this diff to improve error handling:
- return &weaveio.KeyFile{}, fmt.Errorf("failed to generate bridge executor mnemonic: %w", err) + return nil, fmt.Errorf("failed to generate bridge executor mnemonic: %w", err) - return &weaveio.KeyFile{}, fmt.Errorf("failed to generate output submitter mnemonic: %w", err) + return nil, fmt.Errorf("failed to generate output submitter mnemonic: %w", err) - return &weaveio.KeyFile{}, fmt.Errorf("failed to generate batch submitter mnemonic: %w", err) + return nil, fmt.Errorf("failed to generate batch submitter mnemonic: %w", err) - return &weaveio.KeyFile{}, fmt.Errorf("failed to generate oracle bridge executor mnemonic: %w", err) + return nil, fmt.Errorf("failed to generate oracle bridge executor mnemonic: %w", err) - return &weaveio.KeyFile{}, fmt.Errorf("failed to generate challenger mnemonic: %w", err) + return nil, fmt.Errorf("failed to generate challenger mnemonic: %w", err) - return &weaveio.KeyFile{}, fmt.Errorf("unsupported bot name: %s", botName) + return nil, fmt.Errorf("unsupported bot name: %s", botName)models/opinit_bots/bots.go (1)
50-56: LGTM! Consider using this map to simplify key name lookups.The map provides a clear relationship between bot names and key names. Consider refactoring the
BotInfosarray to use this map for key name lookups, which would reduce duplication and make maintenance easier.Example refactor for
BotInfos:var BotInfos = []BotInfo{ { BotName: BridgeExecutor, - KeyName: BridgeExecutorKeyName, + KeyName: string(BotNameToKeyName[BridgeExecutor]), // ... rest of the fields }, // ... similar changes for other entries }models/initialize.go (1)
234-238: Consider improving error handling for home directory access.While the error handling is present, consider wrapping the error with more context about why we need the home directory.
- m.HandlePanic(fmt.Errorf("failed to get user home directory: %w", err)) + m.HandlePanic(fmt.Errorf("failed to get user home directory for storing mnemonic: %w", err))models/minitia/launch.go (3)
2481-2549: LGTM! The mnemonic display changes improve security by removing clipboard functionality.The removal of clickable items and clipboard functionality reduces the attack surface by preventing potential clipboard hijacking. The simplified display using
RenderKeyis a cleaner approach.Consider adding a warning message about not taking screenshots of the mnemonic phrases, as they might be stored in cloud backups. Example:
viewText := m.WrapView(state.weave.Render() + "\n" + styles.BoldUnderlineText("Important", styles.Yellow) + "\n" + - styles.Text(fmt.Sprintf("Note that these mnemonic phrases along with other configuration details will be stored in %s after the launch process. You can revisit them anytime.", configFilePath), styles.Yellow) + "\n\n" + + styles.Text(fmt.Sprintf("Note that these mnemonic phrases along with other configuration details will be stored in %s after the launch process. You can revisit them anytime.\nWarning: Do not take screenshots of these phrases as they may be stored in cloud backups.", configFilePath), styles.Yellow) + "\n\n" + mnemonicText + styles.RenderPrompt(m.GetQuestion(), []string{"`continue`"}, styles.Question) + m.TextInput.View())
2924-2929: Improve error message clarity for end users.The error handling is robust, but the error messages could be more user-friendly.
Consider providing more descriptive error messages:
if err = launchCmd.Wait(); err != nil { if err != nil { - *streamingLogs = append(*streamingLogs, fmt.Sprintf("Launch command finished with error: %v", err)) - return ui.NonRetryableErrorLoading{Err: fmt.Errorf("command execution failed: %v", err)} + userMsg := "Failed to launch the rollup. Please ensure you have sufficient permissions and resources." + *streamingLogs = append(*streamingLogs, fmt.Sprintf("%s\nTechnical details: %v", userMsg, err)) + return ui.NonRetryableErrorLoading{Err: fmt.Errorf("%s\nDetails: %v", userMsg, err)} } }
1-3118: Consider splitting this large file for better maintainability.The file is quite large (3000+ lines) and handles multiple responsibilities. Consider splitting it into smaller, focused files:
- Key management logic
- Configuration handling
- Launch process
- UI components
Suggested structure:
models/minitia/ launch.go # Main launch coordination key_management.go # Key generation and recovery config.go # Configuration handling ui/ display.go # UI components prompts.go # User promptsThis would improve maintainability and make the code easier to test and review.

475-479: Approved for key file writing flow.
The logic of writing to disk and error handling looks correct.
491-491: Consistent retrieval of OPinit key file path.
RetrievingkeyFilePathin the same manner as above ensures consistency across the codebase.
492-495: Graceful error handling.
Good job handling the potential filepath retrieval error and invokingm.HandlePanic(...).
501-501: Consider defensive checks on string splitting.
Similar to the previous block, indexingaddress[1]could cause an out-of-range error ifstrings.Split(...)returns fewer than 2 entries.
515-517: Function refactor looks good.
Replacing mnemonic rendering with address rendering and removing extra parameters aligns with the new approach of focusing on addresses.
1390-1390: Conditional check for Oracle bot key presence.
Ensuring!oracleBotInfo.IsNewKey()is consistent with the feature logic.
1393-1396: Error handling for key file path retrieval.
This block is consistent with the approach used elsewhere.
1403-1403: Duplicate splitting concern.
As with previous code segments, indexingaddress[1]requires a length check if there's any chance the split might fail.models/opinit_bots/init.go (2)
1527-1535: Pointer-based key file usage for the Challenger.
Similar to the executor flow, switching fromKeyFileto*io.KeyFileplus calls toOPInitRecoverKeyFromMnemonichelps unify key management. This appears correct and consistent.
1454-1474: Migrated to pointer-based key file usage for the Executor.
The function signature now takes*io.KeyFileand callsOPInitRecoverKeyFromMnemonicfor each key. This approach is consistent with the new pointer-based logic across the PR. Ensure each call handles errors properly, and consider verifying that the correct mnemonic is returned bykeyFile.GetMnemonic(...).To confirm correct usage and references, check all invocations of
OPInitRecoverKeyFromMnemonic:✅ Verification successful
Pointer-based key file usage and error handling in executor initialization verified
- All calls to
cosmosutils.OPInitRecoverKeyFromMnemoniccorrectly use the pointer-based key file (keyFile.GetMnemonic(...)), and each call properly checks and returns errors.- The invocation in both
models/opinit_bots/init.goandmodels/opinit_bots/setup.gofollows the updated pattern consistently.🏁 Scripts executed

138-155: Verify the impact of empty balances on system functionality.The change to initialize operator and bridge executor addresses with empty balances might affect system functionality. Please ensure that:
- The operator has sufficient funds from other sources to perform operations.
- The bridge executor has sufficient funds to execute bridge operations.
Run the following script to check for any references to these balances in the codebase:
✅ Verification successful
Impact of Empty Genesis Balances Appears Minimal Based on Code References
- The search results show that both the operator and bridge executor balances are declared and used in the genesis accounts, but there are no explicit checks or balance validations (e.g., conditionals) that would fail if these accounts have empty balances.
- Test comments in
models/minitia/state_test.goreference non-empty values (e.g., "100operator" and "200bridge"), indicating that while tests document expected values, the runtime code inFinalizeGenesisAccountssimply assigns an empty balance formatted withls.gasDenom.- It’s implied that sufficient funding for these critical accounts is expected to be provided by subsequent processes. No immediate functionality issues arise from initializing these accounts with empty balances in the genesis state.

2536-2549: Improve error handling in View method.The error handling in the View method could be improved. Currently, if
os.UserHomeDir()fails, the error is handled byHandlePanic, but the method continues execution which could lead to undefined behavior.Consider returning early after error handling:
userHome, err := os.UserHomeDir() if err != nil { - m.HandlePanic(err) + return m.WrapView(state.weave.Render() + "\nError: Failed to get user home directory") }
3034-3036: Enhance service start error handling.The service start error handling could be improved to provide more context and potential recovery steps.
Consider providing more detailed error information and recovery guidance:
if err = srv.Start(); err != nil { - state.weave.PushPreviousResponse(styles.RenderPreviousResponse(styles.NoSeparator, "Failed to start rollup service", []string{}, fmt.Sprintf("%v", err))) + errMsg := fmt.Sprintf("Failed to start rollup service: %v\nPlease ensure no other instances are running and try again.", err) + state.weave.PushPreviousResponse(styles.RenderPreviousResponse(styles.NoSeparator, errMsg, []string{}, "")) }cmd/opinit_bots.go (1)

953-953: Address the TODO comment.The comment indicates a need to check for duplicate keys, but the implementation is missing.
Would you like me to help implement the duplicate key check functionality? This is important for preventing potential key reuse issues.
2438-2438: Consider making the sleep duration configurable.The hardcoded sleep duration of 1500ms might not be optimal for all environments.
Consider making this configurable:
+const defaultKeyGenerationDelay = 1500 * time.Millisecond + func generateOrRecoverSystemKeys(ctx context.Context) tea.Cmd { return func() tea.Msg { // ... - time.Sleep(1500 * time.Millisecond) + time.Sleep(defaultKeyGenerationDelay)
2773-2781: Improve error message specificity in EncodeToBase64.The error message could be more descriptive to help with debugging.
Consider providing more context in the error message:
func (sp *ScanPayload) EncodeToBase64() (string, error) { jsonBytes, err := json.Marshal(sp) if err != nil { - return "", fmt.Errorf("failed to marshal struct: %w", err) + return "", fmt.Errorf("failed to marshal ScanPayload to JSON: %w", err) }
2904-2906: Consider making the log buffer size configurable.The log buffer size is hardcoded to 10 entries, which might not be suitable for all use cases.
Consider making this configurable:
+const defaultLogBufferSize = 10 + func launchingMinitia(ctx context.Context, streamingLogs *[]string) tea.Cmd { // ... - if len(*streamingLogs) > 10 { - *streamingLogs = (*streamingLogs)[1:] + if len(*streamingLogs) > defaultLogBufferSize { + *streamingLogs = (*streamingLogs)[1:] }cmd/opinit_bots.go (1)
179-183: Standardize error wrapping pattern.The error wrapping is inconsistent. Line 179 uses
fmt.Errorfwith%v, while line 183 uses%w. Standardize on using%wfor error wrapping to preserve the error chain.- return fmt.Errorf("error generating keyfile: %v", err) + return fmt.Errorf("error generating keyfile: %w", err)
