12-12: Inconsistent link format for DeBridge DLN FacetThe link to the DeBridge DLN Facet documentation uses an absolute path (
/docs/DeBridgeDlnFacet.md), while other entries use relative paths. Consider updating it to use a relative path for consistency:-- [DeBridge DLN Facet](/docs/DeBridgeDlnFacet.md) ++ [DeBridge DLN Facet](./DeBridgeDlnFacet.md)script/demoScripts/demoDLN.ts (1)

89-99: Enhance error handling and loggingWhile the script includes basic error handling, consider adding more specific error messages and logging throughout the script. This will make it easier to debug issues, especially when dealing with cross-chain operations. For example, you could add try-catch blocks around the API call and transaction submissions.
Here's a suggestion for improved error handling:
try { const resp = await fetch( 'https://api.dln.trade/v1.0/dln/order/quote?srcChainId=42161&srcChainTokenIn=0x912CE59144191C1204E64559FE8253a0e49E6548&srcChainTokenInAmount=5000000000000000000&dstChainId=10&dstChainTokenOut=0x0b2C639c533813f4Aa9D7837CAf62653d097Ff85&prependOperatingExpenses=false' ) if (!resp.ok) { throw new Error(`API request failed with status ${resp.status}`) } const quote = await resp.json() console.log('Quote received:', quote) } catch (error) { console.error('Error fetching quote:', error) process.exit(1) } // Similar try-catch blocks can be added for token approval and bridging operations

1-159: Overall Impact: Enhancing System Functionality and SafetyThe changes in this file introduce two significant improvements to the LiFiDiamond system:
- The addition of
EmergencyPauseFacetenhances the system's safety mechanisms, allowing for emergency pausing if needed.- The introduction of
DeBridgeDlnFacetlikely adds new functionality related to DeBridge DLN, as mentioned in the PR objectives.These changes, along with the replacement of an unnamed facet, improve both the functionality and clarity of the system without affecting other existing components.
To ensure the stability and security of the system with these new additions:
- Conduct comprehensive integration tests to verify that the new facets interact correctly with existing components.
- Update the system documentation to reflect these new facets and their purposes.
- Perform a security audit focused on the new
EmergencyPauseFacetandDeBridgeDlnFacet, especially considering their potential impact on the overall system.- Review and update access control mechanisms to ensure that only authorized entities can interact with these new facets, particularly the emergency pause functionality.

20608-20613:⚠️ Potential issueClarify the purpose of multiple deployment entries for the same contract.
There are two entries for the contract deployed at address
0xaF5001e4cd39B3515B244B18A88DD5b2fE65c5cD:
- Timestamp: 2024-10-08 13:59:43, Verified: true
- Timestamp: 2024-10-08 14:03:01, Verified: false
The presence of multiple entries with different timestamps and verification statuses for the same contract address is unusual.
Please clarify the reason for these multiple entries. Is this a redeployment, an update, or something else? If it's a redeployment, consider removing the older entry to avoid confusion. If it's an update, please provide more context about what changed between these two deployments.
To help understand the differences between these deployments, you can run the following script to compare the contract bytecode:
#!/bin/bash # Description: Compare contract bytecode for different deployments # Note: This script assumes the `gh` CLI is authenticated and has access to the repository secrets # Get the Etherscan API key from GitHub secrets ETHERSCAN_API_KEY=$(gh secret list | grep ETHERSCAN_API_KEY | awk '{print $1}') if [ -z "$ETHERSCAN_API_KEY" ]; then echo "Error: ETHERSCAN_API_KEY not found in GitHub secrets" exit 1 fi # Function to get contract bytecode get_bytecode() { local timestamp=$1 curl -s "https://api.etherscan.io/api?module=proxy&action=eth_getCode&address=0xaF5001e4cd39B3515B244B18A88DD5b2fE65c5cD&tag=latest&apikey=$ETHERSCAN_API_KEY" | jq -r '.result' } # Get bytecode for both deployments BYTECODE_1=$(get_bytecode "2024-10-08 13:59:43") BYTECODE_2=$(get_bytecode "2024-10-08 14:03:01") # Compare bytecodes if [ "$BYTECODE_1" == "$BYTECODE_2" ]; then echo "The contract bytecode is identical for both deployments." else echo "The contract bytecode differs between the two deployments." echo "This suggests that the contract code was modified between deployments." fiThis script will help determine if there are any differences in the contract bytecode between the two deployment entries, which could indicate whether the contract was actually modified or just redeployed.
20594-20599:⚠️ Potential issueVerify the deployed contract for transparency and security.
The contract deployed at address
0xaF5001e4cd39B3515B244B18A88DD5b2fE65c5cDis currently not verified (VERIFIED: "false"). This lack of verification could hinder transparency and make it difficult for users and auditors to inspect the contract's code.Please verify the contract on the blockchain explorer to ensure transparency and facilitate security audits. After verification, update the VERIFIED field to "true".
To check if the contract has been verified since this deployment, you can run the following script:

20594-20610: Summary: Address inconsistencies in the deployment logAfter reviewing the deployment log entries, there are several inconsistencies and potential issues that need to be addressed:
- Future timestamps: Both entries have deployment dates in 2024, which is in the future.
- Duplicate entries: There are two entries for the same contract address with slightly different timestamps.
- Verification status change: The verification status changes from false to true between the two entries.
Recommendations:
- Review and correct the deployment timestamps to reflect the actual deployment dates.
- Clarify the purpose of having multiple entries for the same contract address. If these represent different stages of the deployment process, consider using a more explicit structure to represent this.
- Ensure that the deployment log accurately reflects the current state of the contract, including its verification status.
- Consider implementing a validation process for the deployment log to catch and prevent such inconsistencies in the future.
To improve the structure and consistency of the deployment log, consider the following:
- Implement a versioning system that clearly distinguishes between different deployments or stages of the same contract.
- Use a structured format (e.g., JSON schema) to enforce consistency and prevent invalid entries.
- Automate the process of updating the deployment log to minimize human error.

1-82: Summary of changes and points for verificationThe restructuring of the
config/dln.jsonfile into "networks" and "mappings" sections improves organization and readability. The changes appear to be well-structured and comprehensive. However, there are two main points that require verification:
The use of the same "dlnSource" address (
0xeF4fB24aD0916217251F553c0596F8Edc630EB66) across all networks except Solana. Please confirm if this is intentional and doesn't pose any risks.The unusual chainId (1151111081099710) in the mappings section. Verify if this is correct or if it might be an error.
Once these points are confirmed, the changes can be considered ready for approval.
To assist in the final verification, you can run the following comprehensive script:

2-35: Verify the use of the same "dlnSource" address across networks.The "networks" section is well-structured and includes configurations for multiple networks. However, I noticed that all networks except Solana use the same "dlnSource" address:
0xeF4fB24aD0916217251F553c0596F8Edc630EB66.While this might be intentional, please confirm that using the same address across different networks is the desired behavior and doesn't pose any risks or limitations.
The Solana network correctly uses a different address format, which is expected due to the unique nature of Solana addresses.
To ensure the consistency of the "dlnSource" addresses, you can run the following script:

37-82: Verify the unusual "chainId" in the mappings section.The "mappings" section provides a clear association between chain IDs and their corresponding deBridge chain IDs. Most entries have matching values, which is expected. The different mappings for Gnosis (chainId: 100, deBridgeChainId: 100000002) and Metis (chainId: 1088, deBridgeChainId: 100000004) appear to be intentional and likely reflect network-specific requirements.
However, there's an entry with an unusually large "chainId" (1151111081099710). Please verify if this is correct or if it might be a potential error.
To double-check the chainId mappings, especially the unusual one, you can run the following script:
Please review the output and confirm that all mappings, especially the one with the large chainId, are correct.

Also applies to: 20742-20742
✅ Verification successful
Let me analyze the constructor permissions in the codebase. I'll search for any access control mechanisms related to the constructor and owner.
Based on the analysis of the code, I can now provide a definitive response about the constructor argument address permissions.
The constructor address has appropriate access controls through TransferrableOwnership
The contract inherits from TransferrableOwnership which implements a secure ownership pattern with:
- Initial owner set in constructor
- onlyOwner modifier that checks msg.sender against owner
- Two-step ownership transfer with pending owner pattern
- Proper access control checks and events
The owner has limited capabilities:
- Can transfer ownership (with 2-step verification)
- Can approve tokens for bridges via setApprovalForHopBridges()

18-19: Verify security implications of NON_EVM_ADDRESS in transfer functions.
Since this constant is being introduced for cross-chain operations, we should ensure it's properly validated in transfer functions to prevent potential security issues.
✅ Verification successful
Let me analyze the search results and generate new scripts to verify the security implications.
The previous search revealed that NON_EVM_ADDRESS is used in multiple facets (DeBridgeDlnFacet, MayanFacet, OFTWrapperFacet, WormholeFacet) with proper validation checks and error handling. However, we need to verify the transfer functions in LibAsset.sol to ensure there are no security implications when this address is used.
Based on the search results, I can now provide a final response since we have gathered sufficient information about the security implications:
NON_EVM_ADDRESS constant is properly validated across bridge implementations
The constant is used safely with appropriate validations:
- LibAsset has NULL_ADDRESS checks in transfer functions
- Bridge facets (DeBridge, Mayan, OFTWrapper, Wormhole) implement specific validations:
- DeBridgeDlnFacet: Validates with
EmptyNonEVMAddresserror - MayanFacet: Validates with
InvalidNonEVMReceivercheck - All facets emit
BridgeToNonEVMChainevents for tracking
- DeBridgeDlnFacet: Validates with
- Transfer functions in LibAsset.sol include address validation with
NoTransferToNullAddresserror

18-19: Verify the specific NON_EVM_ADDRESS value.
The chosen address (0x11f111f111f111F111f111f111F111f111f111F1) appears to be intentionally patterned. Let's verify its uniqueness and ensure it's not accidentally colliding with any known addresses.
✅ Verification successful
The search results show that the NON_EVM_ADDRESS constant with value 0x11f111f111f111F111f111f111F111f111f111F1 is consistently used across multiple facets (MayanFacet, WormholeFacet, OFTWrapperFacet, DeBridgeDlnFacet) as a special address to indicate non-EVM chain receivers. This is an intentional pattern used throughout the codebase for cross-chain bridging functionality.
Let me verify the uniqueness of this address pattern:
Based on the search results, I can now provide a definitive verification of the NON_EVM_ADDRESS constant:
The NON_EVM_ADDRESS value is verified as safe and intentionally designed.
The address 0x11f111f111f111F111f111f111F111f111f111F1 is:
- Consistently used across multiple bridge facets (MayanFacet, WormholeFacet, OFTWrapperFacet, DeBridgeDlnFacet) as a special sentinel value
- Used specifically to indicate non-EVM chain receivers in cross-chain bridging operations
- Has a distinct repeating pattern that makes it easily identifiable and unlikely to collide with real addresses
- Is properly validated in the code with specific checks and dedicated events (BridgeToNonEVMChain) when handling non-EVM destinations
- Is defined in LibAsset.sol as a shared constant, ensuring consistency across the protocol

96-110: Optional: Consider Adding Re-initialization Protection
The initDeBridgeDln function lacks a check to prevent re-initialization, which could lead to accidental overwriting of the existing chain ID configurations. While current access control restricts this function to the contract owner, adding a re-initialization guard enhances safety.
If desired, apply this diff to include a re-initialization check:
function initDeBridgeDln(
ChainIdConfig[] calldata chainIdConfigs
) external {
LibDiamond.enforceIsContractOwner();
Storage storage sm = getStorage();
+ if (sm.initialized) {
+ revert AlreadyInitialized();
+ }
for (uint256 i = 0; i < chainIdConfigs.length; i++) {
sm.deBridgeChainId[chainIdConfigs[i].chainId] = chainIdConfigs[i]

}
sm.initialized = true;
emit DeBridgeInitialized(chainIdConfigs);
}Note: A similar suggestion was previously made and acknowledged. Considering past feedback, feel free to disregard if deemed unnecessary.
214-221: Verify Fee Handling Consistency Between ERC20 and Native Tokens
The fee handling differs between ERC20 tokens and native assets. For ERC20 tokens, the _fee is sent separately as value, while for native assets, the _fee is subtracted from orderCreation.giveAmount and the total minAmount is sent as value. This could lead to inconsistencies in the net amount received on the destination chain.
Run the following script to verify the consistency of fee handling:
This script extracts the fee handling logic for both cases to allow for a side-by-side comparison.
✅ Verification successful
Fee handling is correctly implemented for both ERC20 and native tokens
After analyzing the code, the fee handling implementation is actually consistent between ERC20 and native tokens:
-
For ERC20 tokens:
- The full
minAmountis approved and transferred to the DLN source - The
_feeis sent separately as native value with the transaction - The user receives exactly
minAmountof tokens on the destination
- The full
-
For native tokens:
- The
_feeis subtracted fromgiveAmountsince it's part of the same native value - The full
minAmount(which includes both the transfer amount and fee) is sent as value - The user still receives the correct amount (giveAmount - fee) on the destination
- The
This implementation ensures that in both cases:
- The correct fee amount is paid in native tokens
- The user receives the expected amount minus fees on the destination chain

216-216:
Ensure safe subtraction to prevent underflow
In the native asset case, subtracting _fee from orderCreation.giveAmount without checking could cause an underflow if _fee exceeds orderCreation.giveAmount. This would result in a revert due to arithmetic underflow. It's important to ensure that orderCreation.giveAmount is greater than or equal to _fee before performing the subtraction.
Apply this diff to add a check:
+ if (orderCreation.giveAmount < _fee) {
+ revert("Fee exceeds the amount to be sent");
+ }
orderCreation.giveAmount = orderCreation.giveAmount - _fee;76-80:
Validate receiver address length for non-EVM addresses
Currently, the onlyValidNonEVMAddress modifier checks that _deBridgeData.receiver.length is not zero when bridging to a non-EVM address. It would be prudent to also enforce a maximum length to prevent potential issues with excessively long addresses that could lead to increased gas costs or other unintended effects.
Consider adding a maximum length check:
) {
revert EmptyNonEVMAddress();
+ } else if (_deBridgeData.receiver.length > MAX_RECEIVER_ADDRESS_LENGTH) {
+ revert("Receiver address length exceeds maximum allowed");
}Define MAX_RECEIVER_ADDRESS_LENGTH according to the expected maximum address length for your use case.

Add initialization check to prevent function calls before setup
Functions that rely on the deBridgeChainId mapping may revert unexpectedly if the storage is not initialized, as getDeBridgeChainId will revert with UnknownDeBridgeChain().

79-81: Add Maximum Length Check for Non-EVM Receiver AddressCurrently, the
onlyValidNonEVMAddressmodifier checks if_deBridgeData.receiver.lengthis zero when bridging to a non-EVM address. It's advisable to add a maximum length check to prevent excessively long receiver addresses, which could cause potential issues or consume unnecessary gas.Apply this diff to add a maximum length check:
if ( _bridgeData.receiver == LibAsset.NON_EVM_ADDRESS && _deBridgeData.receiver.length == 0 ) { revert EmptyNonEVMAddress(); + } else if (_deBridgeData.receiver.length > MAX_RECEIVER_ADDRESS_LENGTH) { + revert("Receiver address length exceeds maximum allowed"); }Define

Ensure Safe Arithmetic Operation to Prevent Underflow
Subtracting _fee from orderCreation.giveAmount without checking could cause an underflow if _fee exceeds orderCreation.giveAmount. This would result in a revert due to arithmetic underflow. It's important to ensure that orderCreation.giveAmount is greater than or equal to _fee before performing the subtraction.
Apply this diff to add a check:
+ if (orderCreation.giveAmount < _fee) {
+ revert("Fee exceeds the amount to be sent");
+ }
orderCreation.giveAmount = orderCreation.giveAmount - _fee;218-223:
Inconsistent REFERRAL_CODE Usage Between Asset Types
In the non-native asset case, the REFERRAL_CODE is passed to dlnSource.createOrder, but in the native asset case, it is set to zero. This inconsistency may lead to incorrect referral tracking or fee calculations. Ensure that the REFERRAL_CODE is consistently applied in both cases unless there is a specific reason to omit it.
Consider updating the native asset case to include the REFERRAL_CODE:
orderId = dlnSource.createOrder{ value: _bridgeData.minAmount }(
orderCreation,
"",

Verify bridge configuration accuracy
There are potential inconsistencies in the bridge configuration:
- The bridge name is set to "ThorSwap" but we're using DeBridge DLN
- The destination chain ID (100) doesn't match the quote API parameter (100000002)
Consider updating the bridge configuration:
- bridge: 'ThorSwap',
+ bridge: 'DeBridge',53-53: Review security implications of orderAuthorityDst
Setting orderAuthorityDst to the same address as the receiver might have security implications. Additionally, verify that the address packing method is compatible with DeBridge's requirements.
✅ Verification successful
Let me gather more context about the DLN implementation and validation.
Based on the gathered information, I can now provide the final response:
Using same address for receiver and orderAuthorityDst is acceptable
The code review shows that using the same address for both receiver and orderAuthorityDst is a valid pattern, as evidenced by the test cases in DeBridgeDlnFacet.t.sol. The solidityPack method for address encoding is also correct, matching the contract's expected format where both fields are defined as bytes in the DeBridgeDlnData struct. The orderAuthorityDst is properly handled in the contract as orderAuthorityAddressDst parameter.

27-27: 🛠️ Refactor suggestion
Refactor hardcoded API parameters
The DLN quote API call contains several hardcoded values that should be configurable:
- Chain IDs (42161, 100000002)
- Token addresses
- Token amounts
Consider extracting these values to a configuration object:
const config = {
srcChainId: '42161',
dstChainId: '100000002',
srcToken: '0x912CE59144191C1204E64559FE8253a0e49E6548',
dstToken: '0xe91D153E0b41518A2Ce8Dd3D7944Fa863463a97d',
amount: '95000000000000000000'
}✅ Verification successful
Let me verify the chain ID and token addresses by searching for more context.
Let me search for any DLN-specific configuration or documentation.
Let me check the DLN documentation and configuration files.
Let me check the DLN configuration file to verify the chain IDs and token addresses.
Based on the gathered information, I can now provide a final response:
Chain ID 100000002 is the correct DLN bridge chain ID for Gnosis Chain
The DLN configuration file shows a mapping between Gnosis Chain (chainId: 100) and its corresponding DLN bridge chain ID (100000002):
{
"chainId": 100,
"deBridgeChainId": 100000002
}This confirms that the hardcoded chain ID in the API call is correct and follows the protocol's chain ID mapping. The token addresses being used are also standard token addresses on their respective chains.

Refactor to reduce code duplication
The test setup logic is duplicated from test_CanSwapAndBridgeTokensFromNative. Consider extracting common setup into helper functions.
Consider moving test constants to a dedicated section
The Solana address and token values should be moved to constants at the contract level for better maintainability.

Test structure needs improvement
- The test setup is duplicated again. This should be refactored along with the previous test.
- Consider adding more test cases for edge cases, such as:
- Empty orderAuthorityDst
- Invalid chain IDs
- Invalid receiving asset IDs

210-223: Verify the Consistency of value Sent to createOrder
In the non-native asset case, the value sent with dlnSource.createOrder is _fee, whereas in the native asset case, it is _bridgeData.minAmount. This discrepancy may lead to inconsistent behavior. Ensure that the amount of native currency sent with the transaction (value) matches the expected fee in both scenarios.
Please confirm if the value parameters are intended to differ between asset types. If not, consider adjusting the native asset case:
} else {
+ if (orderCreation.giveAmount < _fee) {
+ revert("Fee exceeds the amount to be sent");
+ }
orderCreation.giveAmount = orderCreation.giveAmount - _fee;
- orderId = dlnSource.createOrder{ value: _bridgeData.minAmount }(
+ orderId = dlnSource.createOrder{ value: _fee }(
orderCreation,
"",
REFERRAL_CODE,
""
);
}Alternatively, if the current implementation is correct, no action is needed.

Validate Maximum Length of Non-EVM Receiver Address
The onlyValidNonEVMAddress modifier currently checks if the non-EVM receiver address is empty but does not enforce a maximum length. To prevent potential issues with oversized addresses, consider adding a maximum length check for _deBridgeData.receiver.
Consider adding a maximum length validation:
if (
_bridgeData.receiver == LibAsset.NON_EVM_ADDRESS &&
_deBridgeData.receiver.length == 0
) {
revert EmptyNonEVMAddress();
+ } else if (_deBridgeData.receiver.length > MAX_RECEIVER_ADDRESS_LENGTH) {
+ revert("Receiver address length exceeds maximum allowed");
}Define MAX_RECEIVER_ADDRESS_LENGTH according to your requirements.

Ensure Safe Subtraction of Fees from giveAmount
Subtracting _fee from orderCreation.giveAmount without validation could cause an underflow if _fee exceeds orderCreation.giveAmount. This would revert the transaction due to arithmetic underflow.

Apply this diff to add the necessary check:
