5-5: Import statement updated correctly for ethers v6
The import statement correctly includes toBigInt, BigNumberish, and getNumber from "ethers", aligning with ethers v6 usage.
156-157: Ensure accurate comparison of contract addresses
In the conditional statements at lines 156 and 166, currentRng is compared with randomizerRng.target and blockHashRNG.target. Verify that the properties being compared are of the same type and correctly represent contract addresses.
Ensure that currentRng, randomizerRng.target, and blockHashRNG.target are all normalized to the same format (e.g., lowercase strings) before comparison to prevent any mismatches due to case sensitivity.
Also applies to: 166-169
212-212: Handle potential issues with staticCall in passPeriod
The use of await core.passPeriod.staticCall(dispute.id); simulates the call but does not actually advance the period. Ensure this is the intended behavior and adjust if necessary.
If the goal is to check whether the call would succeed before actually executing it, consider handling the simulation results appropriately. Otherwise, replace staticCall with a direct call to perform the action.
355-361: Verify BigInt arithmetic in delayed stakes calculation
Ensure that the arithmetic operations involving delayedStakesRemaining and delayedStakes correctly handle BigInt values to prevent type errors.
Confirm that all variables involved are of type BigInt and operations like subtraction and comparison are valid.
465-473: Ensure correct phase enumeration mapping
In the functions isPhaseStaking, isPhaseGenerating, and isPhaseDrawing, verify that the phase index obtained from getNumber(await sortition.phase()) correctly maps to the PHASES array.
Ensure that the phases are in the correct order in the PHASES array and that there are no off-by-one errors.
397-403: Check consistency in arithmetic operations with BigInt
At lines 401-403, mixed arithmetic operations involve coherentCount, repartitions, and drawnJurors.length. Ensure that all operands are correctly converted to BigInt before performing calculations.
Explicitly convert drawnJurors.length and repartitions to BigInt if necessary:
const drawnJurorsLength = toBigInt(drawnJurors.length);
const repartitionsNumber = toBigInt(getNumber(repartitions));592-592: Avoid redeclaring the variable dispute in loops
The variable dispute is redeclared in multiple loops within the same scope. This can cause confusion and potential errors. Consider renaming the variable or using block scoping (e.g., let instead of var).

// test/helpers/draw.helper.ts export class DrawTestHelper { static async setStake(wallet: HDNodeWallet, ...args): Promise<void>; static async expectFromDraw(drawTx: Promise<ContractTransactionResponse>, ...args): Promise<void>; // ... other helper methods }contracts/test/arbitration/staking.ts (1)
45-45: Consider using typed contract interactions consistently.While the updates to use
.targetare correct, consider using typed function calls consistently throughout the tests.For example, replace:
-await core["createDispute(uint256,bytes)"](2, extraData, { value: arbitrationCost }); +await core.createDispute(2, extraData, { value: arbitrationCost });This improves type safety and readability while maintaining the same functionality.

3-5: LGTM! The addition of resolveJsonModule aligns with type safety goals.
This change enables proper TypeScript type checking for JSON imports, which is particularly useful for handling contract ABIs and configuration files.
Let's verify the JSON imports in the codebase:
✅ Verification successful
LGTM! The addition of resolveJsonModule is well-justified by actual JSON imports
The codebase shows extensive use of JSON imports across multiple TypeScript files, particularly for:
- Contract artifacts from @kleros/kleros-v2-contracts
- Configuration files for courts and policies
- Test fixtures and templates
- Git information
This confirms that enabling resolveJsonModule is necessary for proper type checking of these imports.

36-36: Verify block number assumptions in tests.
The test cases use specific block numbers (5 and 9876543210) to test past and future scenarios. Let's verify these assumptions are reliable across different test environments.
Also applies to: 43-43
✅ Verification successful
Let me gather more specific information about the block number usage in the RNG tests.
Let me check the BlockHashRNG contract implementation to understand how it uses block numbers.
Let me try to find the contract in a different way.
Let me try one last search without file type restriction.
Based on the contract implementation and test file analysis, I can now provide the final response:
Block number test assumptions are appropriate and well-designed
The test cases use block numbers 5 (past) and 9876543210 (future) to verify the BlockHashRNG contract's behavior, which is correct because:
- The small number (5) ensures it's always in the past, testing the normal case where blockhash is available
- The large number (9876543210) is guaranteed to be in the future for any realistic test environment, properly testing the future block case
- The contract's implementation properly handles both cases, returning 0 for future blocks and using fallback mechanisms for past blocks

Let me verify the function signature and implementation to ensure the callers don't need updates.
Let me try a different pattern to find the function implementation.
Let me try one last search pattern to locate the function.
The bigint change is safe and properly handled
The function implementation shows that faucetFundingAmount is correctly used as bigint throughout the codebase:
- It's passed directly to the
deployFaucetfunction which expects bigint - Used in bigint arithmetic operations (
faucetFundingAmount / 5n) - All callers found earlier only pass the default value, letting

61-61: Verify consistent usage of .target across the codebase.
The change from .address to .target is correct for the updated ethers version. Let's verify this pattern is consistently applied.
✅ Verification successful
Let me analyze the results and generate additional verification scripts to get a complete picture.
The previous results show many instances of .address usage, but we need to see the .target usage to understand if there's a consistent pattern or if some instances of .address should actually be .target. This will help determine if there are any inconsistencies in the ethers.js v6 migration.
Based on the search results, I can now generate the final response since I have enough information to make a determination about the usage of .address vs .target.
Review of .address vs .target usage shows correct patterns
The codebase shows a clear and correct pattern in the usage of .address and .target:
.targetis used when interacting with contract instances (e.g.,core.target,disputeKit.target).addressis used appropriately for:- EOA addresses (e.g.,
wallet.address,deployer.address) - Storage/state variables (e.g.,
klerosCoreAddress) - Configuration and deployment records
- Direct address comparisons
- EOA addresses (e.g.,
The change from .address to .target in the reviewed line is correct and consistent with the codebase's patterns for ethers.js v6 usage.

The toNumber() conversion could potentially lose precision for very large numbers. Consider adding a range check or using a safer conversion method if large values are possible.
contracts/test/arbitration/draw.ts (1)
141-145: 🛠️ Refactor suggestion
Improve transaction receipt error handling.
The current implementation has multiple separate null checks. Consider consolidating them and using more descriptive error messages:
- if (tx.blockNumber === null) throw new Error("tx.blockNumber is null");
- const trace = await network.provider.send("debug_traceTransaction", [tx.hash]);
- const [disputeId] = abiCoder.decode(["uint"], ethers.getBytes(`${trace.returnValue}`));
- const lastBlock = await ethers.provider.getBlock(tx.blockNumber - 1);
- if (lastBlock?.hash === null || lastBlock?.hash === undefined) throw new Error("lastBlock is null || undefined");
+ const receipt = await tx.wait();
+ if (!receipt.blockNumber) {
+ throw new Error("Transaction was not mined: missing block number");
+ }
+ const trace = await network.provider.send("debug_traceTransaction", [tx.hash]);
+ const [disputeId] = abiCoder.decode(["uint"], ethers.getBytes(`${trace.returnValue}`));
+ const lastBlock = await ethers.provider.getBlock(receipt.blockNumber - 1);
+ if (!lastBlock?.hash) {
+ throw new Error("Failed to retrieve previous block hash");
+ }Likely invalid or redundant comment.

735-737: LGTM: Updated contract interaction patterns.
The contract creation and interaction patterns have been properly updated to use the latest ethers conventions, maintaining the same functionality while improving code consistency.
Line range hint 1-748: Verify consistent usage of updated ethers patterns.
The file has been updated to use the latest ethers patterns. Let's verify that all contract interactions follow the new conventions.
✅ Verification successful
Let me modify the search patterns to avoid using look-around assertions and verify the ethers patterns.
Based on the search results, I can see that there are still instances of .address being used in the code, while the file also uses the newer .target pattern. This inconsistency should be addressed. Let me verify if these .address usages are for signers (where it's correct) or for contract instances (where it should be .target).
Based on the context gathered, I can now provide the final verification response:
All ethers patterns are correctly used in this file
The usage of .address and .target is consistent with the latest ethers patterns:
.addressis correctly used only for signers/wallets (e.g.,juror.address,guardian.address).targetis correctly used for contract instances (e.g.,core.target,resolver.target)- Other ethers patterns like
parseUnitsandZeroAddressare also properly used

37-51: Consider adding error handling for token transfers.The changes correctly implement:
- Transition to bigint types
- Usage of .target instead of .address
- Native bigint operations
However, the token transfer could benefit from additional error handling.
Consider adding try-catch and event logging:
- await erc20.transfer(faucet.target, faucetFundingAmount); + try { + const tx = await erc20.transfer(faucet.target, faucetFundingAmount); + await tx.wait(); + console.log(`Successfully funded ${ticker}Faucet with ${faucetFundingAmount}`); + } catch (error) { + console.error(`Failed to fund ${ticker}Faucet:`, error); + throw error; + }contracts/deploy/00-home-chain-arbitration-ruler.ts (1)
36-41: Consider documenting the currency rate parameters.While the implementation is correct, the magic numbers in
changeCurrencyRatecalls (e.g.,12225583, 12) would benefit from comments explaining their significance and calculation.- await changeCurrencyRate(core, await pnk.getAddress(), true, 12225583, 11); + // Rate: 1 PNK = 0.012225583 USD (12 decimals precision) + await changeCurrencyRate(core, await pnk.getAddress(), true, 12225583, 11);contracts/test/arbitration/index.ts (1)
17-33: Consider extracting magic numbers into constantsThe test assertions look good, but consider extracting magic numbers (e.g., 256, 10000) into named constants for better maintainability and readability.
Example:
const JURORS_FOR_COURT_JUMP = 256; const ALPHA = 10000; const DEFAULT_TIMES_PER_PERIOD = [0, 0, 0, 10];Also applies to: 35-39

✅ Verification successful
Let me search for different patterns to verify the consistent usage of BigInt across test files. The previous command might have had syntax issues, so I'm breaking it down into more specific searches.
BigInt usage is consistent and properly implemented across test files
The verification shows consistent usage of BigInt literals (with 'n' suffix) across the test files, particularly in:
- Financial calculations (fees, deposits, stakes)
- Token amounts (ETH and PNK denominations)
- Mathematical operations
The arbitrationFee value of 1000n is consistent with other BigInt usage patterns in the codebase, especially in the test files where similar financial values are handled. No instances of potentially problematic BigNumber or ethers.utils number handling were found that could conflict with this implementation.

2-3: Approved: Necessary imports for updated ethers usage
The addition of toBigInt, BigNumberish, and AddressLike imports is appropriate for utilizing the latest features of the ethers library and enhances type safety throughout the script.
38-41: Approved: Correct argument types for approve function
Using AddressLike and BigNumberish for approvePNKFunctionArgs aligns with the expected types in the approve function of the pnk contract. This ensures type safety and consistency.
257-258: Approved: Correct usage of solidityPackedKeccak256

137-137: Ensure proper conversion for evidenceGroupID
Converting random bytes directly to a BigInt may lead to unintended values or errors. Consider using a hashing function or ensuring the bytes represent a valid number.
Run the following script to verify the value of evidenceGroupID:
✅ Verification successful
Let me analyze the codebase further to understand the usage of evidenceGroupID.
Based on the code analysis, I can now provide a final response:
Converting random bytes to BigInt is safe and appropriate for evidenceGroupID
The usage of toBigInt(ethers.randomBytes(32)) is a secure way to generate a random identifier because:
- The
ethers.randomBytes(32)generates a cryptographically secure 32-byte (256-bit) random value - Converting these bytes to BigInt creates a valid numeric identifier that can be safely used as an evidence group ID
- The evidence system in the contracts accepts and expects numeric IDs in string format
- This pattern is used only for generating unique identifiers, not for cryptographic operations
🏁 Scripts executed
The following scripts were executed for the analysis:
Script:
#!/bin/bash
# Description: Verify that the generated evidenceGroupID is a valid bigint.
# Test: Attempt to convert random bytes to bigint and check for errors.

💡 Codebase verification
Inconsistent usage of parseUnits with BigNumber found
Several files still use BigNumber.from(parseUnits()) which is inconsistent with the migration to bigint:
contracts/deploy/01-foreign-gateway-on-gnosis.ts:ONE_GWEI = BigNumber.from(parseUnits("1", "gwei"))contracts/deploy/04-klerosliquid-to-v2-gnosis.ts:ONE_GWEI = BigNumber.from(parseUnits("1", "gwei"))contracts/deploy/04-foreign-arbitrable.ts:ONE_GWEI = BigNumber.from(parseUnits("1", "gwei"))
These instances should be updated to use bigint directly without wrapping in BigNumber.from().

💡 Codebase verification
Let me analyze the results and generate a final response.
Remaining .address usages need to be updated to .target
The codebase still contains instances where .address should be updated to .target when dealing with contract instances, particularly in:
contracts/scripts/console-init.ts: const requesterID = await rng.requesterToID(disputeKit.address);
Note: Other .address usages are correct as they refer to:
- Wallet/signer addresses (e.g.,
wallet.address,deployer.address) - Deployment addresses (e.g.,
deployment.address) - Contract addresses stored in configuration (e.g.,
disputeKitClassicConfig.address)
