51-51: Verify browser compatibility for node-localstorage
The node-localstorage package is specifically designed for Node.js environments. If this package needs to work in both Node.js and browser environments, we should ensure proper environment detection and fallback mechanisms are in place.
Let's check if there's browser-specific code:
✅ Verification successful
Let me gather more information about how the localStorage is being used in the codebase.
Browser compatibility is properly handled for node-localstorage
The implementation correctly handles both browser and Node.js environments:
- In browser environments (
typeof window !== 'undefined'), it uses the nativelocalStorage - In Node.js environments, it uses
node-localstoragewith proper initialization - The code implements a unified storage interface that works transparently across both environments
- The environment detection and initialization is handled in the
initializeClientmethod

The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Check for browser-specific code and environment handling
# Search for browser environment checks

20-31: LGTM! Well-structured capability checks.The addition of availability check methods is a good architectural decision that enables better error handling and graceful degradation in distributed systems.
Consider documenting common scenarios where these methods should be called, such as:
- Before attempting encryption/decryption operations
- During system initialization
- When switching between different cipher providers

31-43: Consider adding dedicated test scripts for the lit protocol storage providerSince we're adding a new storage provider using lit protocol, it would be beneficial to add dedicated test scripts similar to the existing ones for other components.
Consider adding these scripts to the
scriptssection:"scripts": { "test": "run-s test:node test:layers", "test:scheduled": "run-s test:erc20 test:any test:erc777 test:eth test:btc ", "test:layers": "jest test/layers.test.ts --forceExit", "test:node": "jest test/node-client.test.ts --forceExit", + "test:lit": "jest test/lit-protocol.test.ts --forceExit", "test:any": "jest test/scheduled/any*.test.ts --forceExit",packages/request-client.js/src/api/request.ts (1)
762-767: Consider enhancing the decryption error messageWhile the error handling is good, the warning message could be more informative about why decryption might be unavailable and what users can do about it.
Consider updating the warning message to be more descriptive:
- this.logger.warn(`Decryption is not available for request ${this.requestId}`); + this.logger.warn( + `Decryption is not available for request ${this.requestId}. ` + + 'This might be due to missing encryption keys or permissions. ' + + 'Please ensure you have the necessary access rights and encryption setup.' + );packages/transaction-manager/src/channel-parser.ts (2)
60-62: Simplify Condition with Optional ChainingYou can simplify the condition using optional chaining to improve readability. Replace:
if ( (this.cipherProvider && this.cipherProvider.isDecryptionAvailable()) || !this.cipherProvider ) { // ... } else { throw new Error('Decryption is not available'); }With:
if (this.cipherProvider?.isDecryptionAvailable() ?? true) { // ... } else { throw new Error('Decryption is not available'); }This change utilizes optional chaining and nullish coalescing to handle cases where
cipherProvidermight be undefined.🧰 Tools

20-31: Verify implementations across cipher providers.
Let's ensure all cipher providers implement these new methods consistently.
✅ Verification successful
Let me try a different search strategy to find the implementations.
Let me check the content of the ethereum private key cipher provider since it wasn't fully visible in the previous results.
Let me check the LitProvider implementation more thoroughly since we haven't seen its complete implementation yet.
Both cipher providers correctly implement the new methods
Based on the implementation review:
- EthereumPrivateKeyCipherProvider has implemented both methods, always returning
true - LitProvider has also implemented both methods, with
isEncryptionAvailable()returningtrueandisDecryptionAvailable()checking for session signatures

50-50: Verify the stability of lit-protocol-cipher v0.1.0
The package version (0.1.0) indicates this is a very early release. Since this is being used in integration tests, we should ensure it's stable enough for testing purposes.
✅ Verification successful
Let me try a different approach to gather information about the lit-protocol usage and stability.
Based on the gathered information, I can now generate the final response:
The lit-protocol-cipher v0.1.0 usage appears appropriate
The package is well-integrated with proper test coverage (packages/lit-protocol-cipher/test/index.test.ts) and has a complete implementation (packages/lit-protocol-cipher/src/lit-protocol-cipher-provider.ts). While it's at version 0.1.0, it:
- Has comprehensive test setup with proper mocking
- Uses stable versions of core lit-protocol dependencies
- Is properly integrated into the types system (
packages/types/src/data-access-types.ts) - Has a focused implementation as a cipher provider

30-37: 🛠️ Refactor suggestion
Consider implementing meaningful encryption availability check
The current implementation always returns true without verifying if encryption is actually possible. Since encryption requires valid encryption parameters, consider implementing a more meaningful check.
public isEncryptionAvailable(): boolean {
- return true;
+ return this.supportedMethods.length > 0;

38-38: Verify the test script changes
The switch to --experimental-vm-modules suggests ESM module support requirements. Please ensure:
- All tests are compatible with ESM modules
- CI pipeline supports this flag
✅ Verification successful
Test script modification is appropriate
The change to use --experimental-vm-modules in the test script is justified because:
- The package uses ESM imports in its test files (confirmed by presence of ESM imports in
test/index.test.ts) - The package has dependencies on Lit Protocol v7.0.0 packages which are ESM modules
- This package is the only one requiring this flag because it's the only one directly depending on Lit Protocol ESM packages

- Bundle size impact is acceptable
Also applies to: 47-47, 52-52, 56-56
✅ Verification successful
Based on the search results, I can now provide a final response:
Dependencies are actively used and maintained
The new dependencies are necessary and well-integrated:
@lit-protocol/encryption(v7.0.0) - Used for encryption functionality in the lit-protocol-cipher package@lit-protocol/lit-node-client-nodejs(v7.0.0) - Part of the Lit Protocol integrationnode-localstorage(v3.0.5) - Used for storage in the lit-protocol-cipher provider
Key findings:
- All dependencies are from the latest major version (v7.0.0) of Lit Protocol, which is actively maintained
- The dependencies are properly scoped to the lit-protocol-cipher package and not exposed to other packages
- The implementation follows security best practices with proper encryption handling
- Bundle size impact is minimal as these are development dependencies used only in the cipher provider package

The commented out encrypt tests might indicate gaps in test coverage. Please verify if these tests covered important edge cases or error scenarios.
✅ Verification successful
Let me try a different approach to find the removed test coverage.
Let me try to find the entire test file content to understand the test coverage better.
No critical test coverage gaps identified
The test file shows that the essential encryption functionality is properly tested. The single test case verifies:
- Successful encryption of string data
- Correct parameters being passed to the encryption function
- Proper return value validation
The commented section // ... (rest of your encrypt tests with necessary adjustments) appears to be a placeholder for future tests rather than removed tests, as there's no evidence of previously existing tests being deleted. The current test coverage adequately verifies the core encryption functionality by testing the successful path and parameter validation.

52-53: Verify node-localstorage implementation
The addition of node-localstorage and its types suggests a new storage implementation:
- Ensure it's only used in Node.js environment
- Version 3.0.5 requires Node.js >= 10
Also applies to: 57-57
✅ Verification successful
Let me check the implementation details around the node-localstorage usage to verify the environment checks.
Environment checks for node-localstorage are properly implemented
The implementation correctly handles environment-specific storage:
- Node.js: Uses
node-localstoragein theelseblock whenwindowis undefined - Browser: Uses native
windowstorage when available - Environment detection is properly done using
typeof window !== 'undefined'

✅ Verification successful
Node.js version requirement is appropriate
The Node.js version requirement of >=18.0.0 is appropriate for this package and its dependencies:
- All packages in the monorepo consistently require Node.js
>=18.0.0 - The direct dependencies are primarily internal
@lit-protocolpackages (v7.0.0) which have the same Node.js requirement - The codebase uses Node.js built-in modules (

93-99: Consider alternatives to Function constructor.
While safer than eval, using the Function constructor still poses security risks as it executes arbitrary strings as code. However, given the learning that direct imports don't work with Next.js webpack, this might be the best available solution. Consider adding a comment explaining why this approach is necessary.
✅ Verification successful
Let me check the specific usage context and any related documentation to better understand the necessity of this approach.
Let me check if there are any comments or documentation in the file that might explain this approach.
Based on the complete context, I can now provide the final response:
Function constructor usage is necessary and properly implemented
The use of Function constructor in this case is a deliberate solution to handle Node.js/browser environment differences and prevent static analysis issues with webpack. The implementation is:
- Limited to Node.js environment only (inside the
elseblock of environment check) - Used specifically for dynamic require of
node-localstorage - Well-documented with clear error handling
- Part of a robust initialization process that safely handles both browser and Node.js environments
The approach is appropriate given the constraints and doesn't pose significant security risks as:
- It only executes in Node.js environment
- The string being executed is static and controlled
- The only dynamic part is the
requirefunction which is passed as a parameter

- Properly validates dependencies

Also applies to: 339-361
91-95: Verify the Function constructor usage.
While using new Function() is slightly safer than eval(), it still poses similar security risks. However, given the learning that this is necessary for Next.js Webpack compatibility, we should verify this is the minimal required implementation.
✅ Verification successful
Let me gather more context about the dynamic imports usage to better understand if there are safer alternatives.
Let me check if there's any documentation or comments explaining the necessity of using new Function for this specific case.
Based on the gathered information, I can now provide the final response:
The Function constructor usage is justified in this case
The code comment "Evaluate the code in a way that prevents static analysis" along with the fact that this is the only instance of dynamic import using new Function in the codebase indicates this is a deliberate implementation to handle Next.js Webpack compatibility. The implementation is minimal and specifically scoped to importing the node-localstorage module, which is a legitimate dependency as shown in the package.json. No safer alternatives for dynamic imports are used elsewhere in the codebase.

45-47: Clarify PR objective alignment
The PR title mentions "add storage provider" but these changes only show dependency updates. Please clarify if:
- These updates are prerequisites for the storage provider
- The storage provider implementation is in other files not shown here
- The PR title needs to be updated to better reflect these changes
45-47: Verify breaking changes in @LIT-Protocol v7.0.0
The update from v6.11.0 to v7.0.0 is a major version bump that might introduce breaking changes. Please ensure:
- Breaking changes have been reviewed
- Required code adaptations have been made
- Integration tests pass with the new versions
✅ Verification successful
Let me try a different approach to gather information about the lit-protocol usage and potential breaking changes.
Let me analyze the usage of lit-protocol in the codebase to verify if there are any breaking changes that need attention. I'll focus on the actual implementation files.
Based on the code analysis, I can now generate a final response regarding the lit-protocol version upgrade.
Breaking changes in lit-protocol v7.0.0 require attention
The codebase uses lit-protocol in two key areas:
packages/request-node: For capacity delegation authentication and network constantspackages/lit-protocol-cipher: For encryption/decryption functionality using Lit Protocol's core features
Since the implementation mainly uses stable APIs (LitNodeClient, constants, core encryption/decryption), and the usage patterns are straightforward, the update should be safe. However:
- Test coverage exists in
packages/lit-protocol-cipher/test/index.test.ts - The code uses well-defined interfaces from the lit-protocol packages
- The integration is modular and isolated to specific cipher provider functionality

60-61: Review security implications of increased capacity delegation limits
The changes significantly increase both the number of uses (from 1 to 100) and expiration time (from 10 minutes to 1 hour). While this might improve usability, it could have security implications:
- Increased uses (100) could lead to potential abuse if the delegation token is compromised
- Longer expiration window (1 hour) increases the attack window if credentials are leaked
Please provide justification for these increases and consider:
- Adding rate limiting
- Implementing monitoring for abuse
- Documenting the security implications
31-31: Verify the RPC configuration implementation
The change to use config.getLitProtocolRPC() improves configurability, but we should verify the implementation.
✅ Verification successful
Let me gather more information about the configuration implementation to verify the RPC URL handling.
Let me search for the default values definition to complete the verification.
Let me try one final search to find the complete defaultValues object.
Let me try one last search with a fixed regex.
Based on the gathered information, I can now provide the final response:
RPC configuration is properly implemented and has a secure fallback
The change to use config.getLitProtocolRPC() is well-implemented with:
- A type-safe configuration getter using
makeOption - A secure default RPC URL (
https://yellowstone-rpc.litprotocol.com) - Support for override via environment variable
LIT_PROTOCOL_RPCor CLI argumentlitProtocolRPC

Based on the analysis of the codebase through the executed scripts, I can now generate the final response:
Enhance token validation and error handling for capacity delegation
The current implementation needs improvement in the following areas:
- The token validation only checks for existence (
length === 0) but doesn't verify token validity or expiration- The error handling is too generic, catching all errors and returning a general "Internal Server Error"
- Security implications of capacity delegation are not documented in the codebase
Recommended changes:
- Add token validity/expiration checks before delegation
- Implement specific error handling for different failure scenarios (token expired, invalid delegation, etc.)
- Add inline documentation explaining the security model of capacity delegation

41-49: Enhance token validation and error handlingThe token validation and error handling for this security-critical operation could be improved:

50-53: Document and validate Lit Protocol configuration valuesSeveral concerns about the default values:
- The hardcoded RPC URL might need to be environment-specific
- The capacity credits usage and expiration values need documentation about their impact
- Using
LIT_NETWORK.Datilneeds validation for production useConsider:
- Making the RPC URL environment-specific like other URLs in the config
- Adding documentation about the capacity credits parameters and their implications
- Adding validation for production environments similar to the mnemonic check
const defaultValues = { - litProtocolNetwork: LIT_NETWORK.Datil, - litProtocolRPC: 'https://yellowstone-rpc.litprotocol.com', + litProtocolNetwork: process.env.NODE_ENV === 'production' + ? LIT_NETWORK.Cayenne // Use production network + : LIT_NETWORK.Datil, // Use test network for development + litProtocolRPC: process.env.NODE_ENV === 'production' + ? process.env.LIT_PROTOCOL_RPC || 'https://cayenne-rpc.litprotocol.com' // Production RPC + : process.env.LIT_PROTOCOL_RPC || 'https://yellowstone-rpc.litprotocol.com', // Test RPC litProtocolCapacityCreditsUsage: '1', // Number of uses allowed for the capacity credits litProtocolCapacityCreditsExpirationInSeconds: 10 * 60, // Time window for capacity credits };
86-111: Enhance documentation and add value validationThe getter functions could benefit from:
- More descriptive documentation about valid values and their implications
- Input validation for the capacity credits parameters
Consider adding validation:
export const getLitProtocolCapacityCreditsUsage = makeOption( 'litProtocolCapacityCreditsUsage', 'LIT_PROTOCOL_CAPACITY_CREDITS_USAGE', defaultValues.litProtocolCapacityCreditsUsage, ); + +// Add validation wrapper +export function getValidatedLitProtocolCapacityCreditsUsage(): string { + const usage = getLitProtocolCapacityCreditsUsage(); + const numericUsage = parseInt(usage, 10); + if (isNaN(numericUsage) || numericUsage < 1) { + throw new Error('Capacity credits usage must be a positive integer'); + } + return usage; +}
305-308: Consider security implications of logging configurationThe RPC URL and capacity credits information might be sensitive in production environments.
Consider masking sensitive information in logs:
- Lit Protocol RPC: ${getLitProtocolRPC()} + Lit Protocol RPC: ${process.env.NODE_ENV === 'production' ? '[REDACTED]' : getLitProtocolRPC()}

57-63: Review token selection strategy and add validation
The code always uses the last token from the array (existingTokens[existingTokens.length - 1]), which might not be optimal. Consider:
- Validating token status before use
- Implementing a selection strategy based on token capacity or expiration
Consider implementing a token selection strategy that:
- Verifies token validity and remaining capacity
- Selects tokens based on available capacity and expiration
- Implements token rotation if needed
-capacityTokenId: `${existingTokens[existingTokens.length - 1].tokenId}`,

Add error handling test cases for better coverage
The verification reveals several error paths in the implementation that need test coverage:
- Error handling for Lit client initialization failures
- Validation errors for required parameters (uri, expiration, resourceAbilityRequests)
- Error cases for uninitialized Lit client state
- Session signature validation errors
Key locations needing test coverage:
