contracts/src/staking/DepositContract.sol (10)
34-34: Confirm the correctness of ONE_DAY constant
The ONE_DAY constant is defined as 86,400 seconds. Verify that this duration fits the intended delay for operator changes within your system.
67-69: Proper implementation of supportsInterface
The supportsInterface function correctly checks for the implemented interfaces ERC165 and IDepositContract.
71-73: Ensure getOperator handles unregistered pubkeys
The getOperator function returns the operator associated with a given pubkey. Confirm that it correctly handles cases where the pubkey is unregistered, returning address(0) as expected.
Line range hint 90-99: Input validation checks are appropriate
The length checks for pubkey, credentials, and signature are correctly implemented to ensure data integrity.
102-115: Operator assignment logic in deposit function
The logic for setting the operator on the first deposit and preventing changes on subsequent deposits is sound. Ensure this behavior aligns with the intended security model to prevent unauthorized operator changes.
132-149: Validate operator change request logic
The requestOperatorChange function properly restricts requests to the current operator and checks for zero address. Ensure that edge cases, such as unregistered pubkeys and reentrancy, are adequately tested.
210-213: Review assembly code for ETH transfer
The assembly code in _safeTransferETH handles the ETH transfer. Ensure it is secure against reentrancy attacks and correctly handles failures.
78-85:
Update all calls to deposit with new parameter
The deposit function now includes an address operator parameter. Ensure that all calls to deposit within the codebase are updated to pass the correct operator value.
Run the following script to identify all deposit function calls that may need updating:
✅ Verification successful
The previous command had an incorrect flag. Let's try with the correct ripgrep syntax to find deposit function calls and also look for the interface definition to understand how it was used before.
Let's first check available file types and then search using file glob pattern instead of file type. This should help us find the deposit function calls and interface definition in Solidity files.
Based on the search results, I can now generate the final response:
All deposit calls are already updated with the operator parameter
The search results show that there are only two implementations of the deposit function:
- The main implementation in
contracts/src/staking/DepositContract.sol - A test implementation in
contracts/test/staking/PermissionedDepositContract.solwhich correctly callssuper.deposit(pubkey, withdrawal_credentials, signature, operator)
No other direct calls to the deposit function were found in the codebase that would need updating.

Line range hint 186-196: Verify intent of sending ETH to zero address
The _deposit function sends msg.value to address(0), effectively burning the ETH. Confirm that this is the intended behavior for handling deposits.
Run the following script to review calls to _safeTransferETH and confirm the intent:
✅ Verification successful
Sending ETH to zero address is intentional and documented
The code analysis reveals this is intended behavior:
- There's an explicit documentation comment:
/// @dev Validates the deposit amount and sends the native asset to the zero address. - This is part of the staking contract's deposit mechanism, where ETH is effectively burned (removed from circulation) as part of the staking process.
- The implementation is consistent with the documented behavior and appears to be a deliberate design choice.

14-14: Change from abstract to concrete contract
The DepositContract has been changed from an abstract contract to a concrete one. Ensure this change aligns with the overall architecture and that instantiation of this contract does not introduce unintended behaviors.
Run the following script to check for instantiations of DepositContract:
✅ Verification successful
Based on the search results, we can see that DepositContract is being used as a base contract by PermissionedDepositContract in the test directory. This suggests that the contract needs to be concrete (not abstract) to allow for proper inheritance and implementation. The change from abstract to concrete appears intentional to support this testing scenario.
Change from abstract to concrete contract is appropriate
The modification to make DepositContract a concrete contract is justified as:
- It is being inherited by
PermissionedDepositContractin the test suite - The contract implements all necessary functionality from
IDepositContractandERC165 - No unimplemented functions are present that would require it to be abstract

34-35: Auto-generated ABI and bytecode updated
The ABI and bytecode have been updated to include the latest contract changes. This reflects the additions and modifications in the smart contract.
267-296: Added GenesisDepositsRoot function
The GenesisDepositsRoot accessor functions have been correctly added to retrieve the genesis deposits root from the contract.
298-327: Added GetOperator function
The GetOperator functions allow retrieval of the operator address associated with a given validator's public key. Ensure these functions are utilized where necessary in the codebase.
391-434: Added QueuedOperator function
The QueuedOperator functions have been added to access queued operator changes. This enables viewing pending operator updates for validators.
467-486: Added AcceptOperatorChange function
The AcceptOperatorChange functions facilitate the acceptance of a queued operator change. Confirm that appropriate permissions and validations are in place when invoking this function.
509-528: Added CancelOperatorChange function
The CancelOperatorChange functions enable cancellation of a queued operator change request. This provides flexibility in managing operator updates.
572-590: Updated Deposit function signature
The Deposit function signature now includes the operator parameter:
func (_BeaconDepositContract *BeaconDepositContractTransactor) Deposit(opts *bind.TransactOpts, pubkey []byte, withdrawal_credentials []byte, signature []byte, operator common.Address) (*types.Transaction, error)Ensure that all invocations of this function are updated to match the new signature.
815-957: Added event handling for OperatorChangeCancelled
Event structures and iterators for the OperatorChangeCancelled event have been added. This allows the contract to handle cancellations of operator change requests effectively.
959-1105: Added event handling for OperatorChangeQueued
The OperatorChangeQueued event and its corresponding structures and iterators have been introduced, enabling tracking of queued operator changes.
1106-1250: Added event handling for OperatorUpdated
Event structures and iterators for the OperatorUpdated event have been implemented. This facilitates monitoring of operator updates upon successful changes.
884-885: Consistent use of Pubkey types in event structures
In the event structures BeaconDepositContractOperatorChangeCancelled, BeaconDepositContractOperatorChangeQueued, and BeaconDepositContractOperatorUpdated, the Pubkey field is of type common.Hash due to it being indexed in the event. This is appropriate as indexed event parameters are represented as hashes.

29-30: Verify the validation implementation for withdrawal addresses
Let's verify how these constants are used in the validation logic for the mentioned commands.
✅ Verification successful
Let me gather more information about the validation logic by searching for address validation patterns.
Let me search for more specific validation logic around withdrawal addresses.
Let me check the validation implementation in the types package and the execution address conversion.
Based on the gathered information, I can now generate the final response:
Withdrawal address validation is properly implemented
The withdrawal address validation is enforced through multiple layers:
- Basic empty check:
if withdrawalAddress == "" { return errors.New("non zero withdrawal address is required") } - Hex conversion validation:
NewExecutionAddressFromHexwhich useshex.MustToBytes - Proper credential formatting:
NewCredentialsFromExecutionAddresswhich enforces the ETH1 credential prefix and proper address byte layout

contracts/test/staking/PermissionedDepositContract.sol (2)
52-52: Implementation correctly handles permissions and parent contract call
The updated super.deposit call properly aligns with the new signature while maintaining the existing permission checks. The implementation is secure and appropriate for a test contract.
42-43: Verify deposit function signature alignment with parent contract
The function signature has been updated to remove the amount parameter and add operator. Let's verify this matches the parent contract's interface.
✅ Verification successful
Function signature matches parent contract interface
The deposit function signature in PermissionedDepositContract.sol correctly aligns with both the parent DepositContract and IDepositContract interfaces. All implementations have the same parameters in the same order:
- bytes calldata pubkey
- bytes calldata credentials/withdrawal_credentials
- bytes calldata signature
- address operator
The only minor difference is the parameter name "withdrawal_credentials" vs "credentials" which is just a naming variation and doesn't affect the interface compatibility.

mod/cli/pkg/utils/parser/validator.go (2)
24-24: LGTM!
The fmt import is correctly added and necessary for error formatting in the new function.
49-65: 🧹 Nitpick (assertive)
Consider improving error handling and validation
While the function correctly handles invalid addresses through panic recovery, consider these improvements:
- Add pre-validation of the address format (e.g., hex prefix, length) before conversion
- Provide more specific error messages indicating the exact validation failure
- Consider working with the
commonpackage maintainers to modifyNewExecutionAddressFromHexto return an error instead of panicking
Here's a suggested improvement:
func ConvertWithdrawalAddress(address string) (common.ExecutionAddress, error) {
+ // Validate address format
+ if !strings.HasPrefix(address, "0x") {
+ return common.ExecutionAddress{}, fmt.Errorf("invalid withdrawal address: missing 0x prefix")
+ }
+ if len(address) != 42 { // 0x + 40 hex chars
+ return common.ExecutionAddress{}, fmt.Errorf("invalid withdrawal address: incorrect length")
+ }
+ if !regexp.MustCompile("^0x[0-9a-fA-F]{40}$").MatchString(address) {
+ return common.ExecutionAddress{}, fmt.Errorf("invalid withdrawal address: invalid hex format")
+ }
+
// Wrap the call in a recover to handle potential panics from invalid
// addresses.
var (
addr common.ExecutionAddress
err error
)
defer func() {
if r := recover(); r != nil {
- err = fmt.Errorf("invalid withdrawal address: %v", r)
+ err = fmt.Errorf("invalid withdrawal address: failed to convert - %v", r)
}
}()
addr = common.NewExecutionAddressFromHex(address)
return addr, err
}Let's verify how this function is being used in the codebase:
mod/cli/pkg/commands/deposit/create.go (2)
48-48: LGTM: Clear and consistent terminology update
The command description now correctly reflects the use of "withdrawal address" instead of "withdrawal credentials", maintaining clarity about the expected arguments.
83-89: LGTM: Proper withdrawal address validation flow
The code properly validates and converts the withdrawal address before creating credentials.
Let's verify the implementation of the new parser function:
✅ Verification successful
LGTM: Withdrawal address validation is properly implemented
The implementation in mod/cli/pkg/utils/parser/validator.go shows that ConvertWithdrawalAddress properly validates addresses by:
- Using a panic recovery to catch invalid addresses
- Converting hex strings to execution addresses via
common.NewExecutionAddressFromHex - Returning appropriate errors for invalid addresses
The code is well-structured and handles validation correctly before creating credentials.

Enhance withdrawal address documentation and validation
Given that this is a critical flag for validator creation and premined deposits (as per PR objectives), consider:
- Enhancing the message to specify the expected format (hex address)
- Adding validation to ensure the address is not the Zero Address
withdrawalAddressFlag = "withdrawal-address"
-withdrawalAddressFlagMsg = "The address to withdraw funds to"
+withdrawalAddressFlagMsg = "The Ethereum hex address (e.g., 0x...) to withdraw funds to. Must not be the Zero Address"Let's verify if there's proper validation for the Zero Address:

Review hardcoded values and improve signature handling.
The implementation has several areas that could be improved:
- The gas limit is hardcoded to 600000
- The signature is an empty byte array
- The 32 ETH value calculation could be more explicit
Let's verify the gas usage pattern:
Consider these improvements:
- val, _ := big.NewFloat(32e18).Int(nil)

Reorder time comparison to prevent potential overflow in acceptOperatorChange
The expression queuedTimestamp + ONE_DAY > block.timestamp may cause an overflow if queuedTimestamp is close to the maximum value of uint96. Reordering the condition prevents this potential overflow.
Apply this diff to prevent the overflow:
- if (queuedTimestamp + ONE_DAY > uint96(block.timestamp)) {
+ if (block.timestamp < queuedTimestamp + ONE_DAY) {
revert NotEnoughTime();
}128-131: 🧹 Nitpick (assertive)
Consider moving amount check into _deposit function for better encapsulation
Currently, the check if (amountInGwei < MIN_DEPOSIT_AMOUNT_IN_GWEI) occurs after calling _deposit(). For better encapsulation and to keep amount validations within the deposit handling, consider moving this validation inside the _deposit function.
Apply this diff to move the check:
// In function _deposit()
function _deposit() internal virtual returns (uint64) {
if (msg.value % 1 gwei != 0) {
revert DepositNotMultipleOfGwei();
}
uint256 amountInGwei = msg.value / 1 gwei;
if (amountInGwei > type(uint64).max) {
revert DepositValueTooHigh();
}
+ if (amountInGwei < MIN_DEPOSIT_AMOUNT_IN_GWEI) {
+ revert InsufficientDeposit();
+ }
_safeTransferETH(address(0), msg.value);
return uint64(amountInGwei);
}And remove the check from the deposit function:
uint64 amountInGwei = _deposit();
- if (amountInGwei < MIN_DEPOSIT_AMOUNT_IN_GWEI) {
- revert InsufficientDeposit();

318-327: Verify CometBFT compatibility and performance impact.
The pre-allocation of transaction results needs verification to ensure:
- Compatibility with CometBFT's expected behavior for skipped transactions
- Performance improvement in real-world scenarios with varying transaction loads
✅ Verification successful
Skip decoding behavior is appropriate for non-SDK transactions
The code change is verified to be correct and safe based on the following findings:
- The comment directly above the code explains the intention: "Not all raw transactions may adhere to the sdk.Tx interface, e.g. vote extensions, so skip those"
- The code is part of the
ProcessProposalmethod which handles both SDK and non-SDK transactions - The default behavior of marking non-SDK transactions with code 2 and "skip decoding" is a proper way to handle transactions that aren't meant to be processed by the SDK
The implementation aligns with CometBFT's expectations by:
- Pre-allocating results array for performance
- Using a consistent error code (2) for skipped transactions
- Properly handling mixed transaction types in proposals

29-31: Verify zero address default handling
Setting defaultWithdrawalAddress to zero address could be risky if not properly validated, as it could lead to locked funds with no withdrawal capability.
Let's verify how this default value is validated:
✅ Verification successful
Zero address is properly validated through withdrawal credentials system
The codebase shows that the zero address withdrawal handling is secure for the following reasons:
-
The withdrawal address is validated through
ConvertWithdrawalAddresswhich:- Has panic recovery for invalid addresses
- Returns proper error messages for invalid addresses
- Is used consistently in both deposit and genesis commands
-
The zero address is only used as a default value in flags, but actual withdrawals go through:
- Proper withdrawal credentials conversion via
NewCredentialsFromExecutionAddress - State transition validation in
statedb.go - Deposit message verification via
VerifyCreateValidator
- Proper withdrawal credentials conversion via
The zero address default is a common pattern in Ethereum for unset addresses and the codebase has proper validation before any actual withdrawal operations.

Fix the loop syntax and consider verifying intermediate transactions.
There are two issues with the current implementation:
-
Incorrect loop syntax: Since
NumDepositsLoadis an integer, the loop should use a traditional for-loop syntax for numeric iteration. - Lack of intermediate transaction verification: It's advisable to verify at least a subset of the intermediate transactions to catch potential failures early in the process.

Based on the gathered information, I can now provide a final response:
Withdrawal credentials format is properly validated in the codebase
The withdrawal credentials implementation in consensus-types/types/withdrawal_credentials.go follows the correct format:
- Uses
EthSecp256k1CredentialPrefix(0x01) as the first byte - Includes 11 bytes of zero padding
- Copies the execution address into the last 20 bytes

14-15: Consider making the owner address more configurable
The hardcoded owner address reduces test flexibility. Consider:
- Using a dynamic address generation via
makeAddr()in thesetUpfunction.
195-197: Add NatSpec documentation for the helper function
The _newPubkey function would benefit from NatSpec documentation explaining its purpose and parameters.

38-44: Note: This is an auto-generated file
This file is auto-generated by abigen. Manual changes will be lost when the code is regenerated. Ensure any required changes are made in the source ABI or the generating script.

25-25: Update the go:generate command to reflect the new contract paths
The go:generate command has been correctly updated to reference the new DepositContract.sol. Ensure that the paths to the ABI and binary files are accurate and that abigen generates the bindings successfully.

31-33: Ensure consistency in renamed types and functions
The renaming from BeaconDepositContractInput to DepositContractInput and ProvideBeaconDepositContract to ProvideDepositContract is appropriate. Please ensure that all references to these types and functions throughout the codebase and documentation are updated accordingly.

36-42: LGTM! Clean generic type implementation.
The generic type parameters and constraints are well-defined, providing type safety for deposit handling.
Line range hint 75-116: Verify error handling in deposit event processing.
The deposit event processing looks correct, but we should verify that all error cases are properly handled when processing malformed event data.
✅ Verification successful
The previous pattern didn't yield results, so I'm broadening the search to:
- Look for FilterDeposit implementations with context
- Find similar error handling patterns
- Search for byte conversion patterns to verify consistency in error handling
Based on the search results, I can now generate the final response:
Error handling for deposit event processing is properly implemented
The implementation correctly handles all potential error cases when processing deposit events:
- Validates and converts public key (48 bytes) with proper error handling
- Validates and converts withdrawal credentials (32 bytes) with proper error handling
- Validates and converts signature (96 bytes) with proper error handling
- Returns early with descriptive error messages if any conversion fails
- No other implementations in the codebase handle these conversions differently
The error handling is consistent and follows best practices by:
- Immediately stopping processing on first error
- Wrapping errors with context using fmt.Errorf
- Providing specific error messages that identify which field failed

61-62: 🧹 Nitpick (assertive)
Document the significance of hardcoded values.
The withdrawal address and deposit amount are hardcoded. Consider:
- Adding comments explaining the significance of these values
- Ensuring consistency with values used in other configuration files
- Making these values configurable through higher-level configuration
✅ Verification successful
Let me generate the final response based on the search results.
Add documentation for the hardcoded withdrawal address and deposit amount
The withdrawal address (0x20f33ce90a13a4b5e7697e3544c3083b8f8a51d4) and deposit amount (32000000000) are consistently used across multiple configuration files and are documented in the README.md. However, their significance should be better documented in the code:
- Add a comment in
kurtosis/src/nodes/consensus/beacond/node.starexplaining:- The withdrawal address is a pre-funded genesis account (as mentioned in README.md)
- The deposit amount represents 32 ETH in Gwei (required for validator deposits)
- Whether these values should be configurable or must remain fixed for the network to function correctly

53-56: LGTM! Clear command description and argument validation.
The command structure is well-defined with clear documentation of expected arguments and their order.
92-94:
Add validation for withdrawal address format.
The direct conversion of the withdrawal address without validation could lead to runtime panics with invalid input.
Add validation before conversion:
-withdrawalAddress := common.NewExecutionAddressFromHex(args[1])
+if !common.IsHexAddress(args[1]) {
+ return fmt.Errorf("invalid withdrawal address format: %s", args[1])
+}
+withdrawalAddress := common.NewExecutionAddressFromHex(args[1])Likely invalid or redundant comment.

200-204: LGTM! Proper transaction options setup.
The transaction options are correctly configured with all necessary parameters.
94-97: 🧹 Nitpick (assertive)
Consider batching transaction receipts.
Waiting for receipt only on the last transaction might miss failures in earlier transactions.
Consider batching receipt checks:
var (
tx *coretypes.Transaction
receipt *coretypes.Receipt
)
+const batchSize = 50
for i := range NumDepositsLoad {
tx, err = s.generateNewDepositTx(...)
s.Require().NoError(err)
- if i == NumDepositsLoad-1 {
+ if (i+1)%batchSize == 0 || i == NumDepositsLoad-1 {
receipt, err = bind.WaitMined(...)
s.Require().NoError(err)
s.Require().Equal(coretypes.ReceiptStatusSuccessful, receipt.Status)
}
}Likely invalid or redundant comment.

44-44: LGTM! Consistent component naming.
The component rename aligns with the broader refactoring of deposit contract naming across the codebase.

132-132: LGTM: Command structure aligns with PR objectives.
The updated command correctly incorporates the deposit amount and withdrawal address parameters in the expected order.

288-291: LGTM: Type alias update aligns with standardization efforts.
The change from WrappedBeaconDepositContract to WrappedDepositContract maintains the same functionality while following the new naming conventions.
