⚠️ Potential issue

Address potential security and gas optimization concerns in the multi-call implementation.

The current implementation has several areas that need attention:

  1. No validation for array length matching between receiverArray and zrc20Array
  2. Multiple external calls in a loop could lead to high gas costs
  3. No checks for array length limits

Consider implementing these improvements:

 function callMulti(
     bytes[] memory receiverArray,
     address[] memory zrc20Array,
     bytes calldata messages,
     CallOptions memory callOptions,
     RevertOptions memory revertOptions
 ) external {
+    if (receiverArray.length != zrc20Array.length) {
+        revert("Array lengths mismatch");
+    }
+    if (receiverArray.length == 0) {
+        revert("Empty arrays");
+    }
+    if (receiverArray.length > 10) {  // Adjust limit based on gas considerations
+        revert("Too many calls");
+    }
+
+    uint256[] memory gasFees = new uint256[](zrc20Array.length);
+    // Batch all checks first
+    for (uint256 i = 0; i < zrc20Array.length; i++) {
+        (, gasFees[i]) = IZRC20(zrc20Array[i])
+            .withdrawGasFeeWithGasLimit(callOptions.gasLimit);
+        if (!IZRC20(zrc20Array[i]).transferFrom(
+            msg.sender,
+            address(this),
+            gasFees[i]
+        )) {
+            revert TransferFailed();
+        }
+    }
+
+    // Then batch all approvals and calls
+    for (uint256 i = 0; i < zrc20Array.length; i++) {
+        IZRC20(zrc20Array[i]).approve(address(gateway), gasFees[i]);
         gateway.call(
             receiverArray[i],
             zrc20Array[i],
             messages,
             callOptions,

🛠️ Refactor suggestion

Enhance environment variable validation.

The configuration directly uses process.env.PRIVATE_KEY without validation. Add checks to ensure the private key is properly set.

Add this validation before the config:

dotenv.config();

+if (!process.env.PRIVATE_KEY) {
+  throw new Error("PRIVATE_KEY environment variable is required");
+}
+

⚠️ Potential issue

Add compiler configuration to resolve pipeline failures.

The pipeline is failing due to missing Solidity compiler configuration. Add the compiler settings to support the required versions.

Apply this diff to resolve the compiler configuration:

+ solidity: {
+   version: "0.8.21",

💡 Codebase verification

Remove or document unused Solana dependency

The @zetachain/protocol-contracts-solana dependency appears to be unused in the codebase. Either:

  • Remove the dependency if it's not needed
  • Document its intended usage and implement the Solana integration
🔗 Analysis chain

Verify Solana contract integration requirements.

The addition of @zetachain/protocol-contracts-solana suggests new Solana integration capabilities. Ensure this dependency is required and properly documented in the project's README.

Run this script to check for Solana-related configuration and documentation:
