Root Cause

The contract uses Solidity ^0.8.13, and newer compiler versions may introduce opcodes like PUSH0 that are not supported on all Ethereum Virtual Machine (EVM) compatible chains, especially some Layer 2 solutions.

Impact

Deploying the contract on networks that do not support these newer opcodes will fail, rendering the contract unusable on those chains. This limits the contract's compatibility and accessibility.

Recommendations

• Specify EVM Version: Set the EVM version explicitly in the compiler settings to ensure compatibility:

  // In the compiler settings

  "evmVersion": "Berlin"

• Test on Target Chains: Before deployment, test the contract on all intended networks to ensure compatibility.
