Ethereum: Getting invalid opcode: PUSH0 on ARB and not on BSC for the same contracts interactions
Ethereum: Invalid opcode error on the intelligent arbiter chain and binance
As a developer who works on ETHREUM-based DApps, you have probably encountered problems when you interact with the smart contracts implemented on both Binance Smart Chain (BSC) and the arbitrum. Such a problem that has affected the developers is the “Invalid OPCod” error, which can occur when using proxied contracts on these networks.
In this article, we will deepen the error of the “invalid opcode”, as caused by invalid options and will provide guidance on troubleshooting and solving problems in your BSC and ARB projects.
What is an invalid opcode error?
The “invalid opcode” error occurs when a contract tries to invoke an opcode code that does not exist. This can happen for several reasons, including:
- Opcodes defined incorrectly
- Opcodes or non -existent functions are called
- Arguments outside the range that have been transmitted
In the context of proxied contracts, this error often occurs when using the Ethereum Virtual Machine (EVM) -generated by a proxy contract.
Causes of invalid opcode error on BSC
On Binance Smart Chain (BSC), errors caused by invalid opcodes can be attributed to several factors:
* Incorrect opcode : If a contract defines an OPCOD code that does not exist in EVM, it will throw an “Invalid OPCode” error.
* Opcodes or non -existent functions : If a proxy contract resorts to a function or function that is not defined in bytecode, it will cause an “invalid opcode” error.
Causes of invalid opcode error on the referee
On the referee, the errors caused by the Invalid Opcodes can be assigned:
* Incorrect opcodes : Similar to BSC, incorrect opcodes can lead to “Invalid Opcode” error.
* Arguments outside the range : passing an argument that is outside the valid interval for a certain functional code or call will result in an “Invalid OPCode” error.
troubleshooting steps
To solve invalid opcode errors on BSC and Arbitrum, follow these troubleshooting steps:
1. Review of the contract code
Before implementing a contract to BSC or ARB, review the source code to ensure that all OPCOD codes are defined correctly and no crucial functionality is lacking.
2. Check if there are non -existent options
Verify that the contract defines all the necessary codes and functions before implementation.
####. Check the argument range
Make sure that the intervals of arguments for opcode calls match the expected interval. For example, if an OPCode requires a specific type of value (for example, UNT256), check that the contract by the contract includes this functional call with the correct arguments.
4. Use ethers.js or web library3
When you interact with smart contracts, consider using libraries such as Ethers.JS or Web3 to help validate and sanitize your code before implementation. These libraries provide functions such as:
- Code validation: checks syntax errors and invalid option codes
- Sanitization of arguments: It is ensured that the arguments are in the valid interval
5. Journal errors
When you encounter an “Invalid OpCod” error, connect it using a logging library such as Ethers.JS or web3 console. This will help you diagnose the problem more efficiently.
Conclusion
Invalid OPCOD errors can be frustrating when working on Ethereum-based DApps, but they are relatively easy to solve with the right troubleshooting tools and EVM Bytecode knowledge. Following these troubleshooting steps, developers can identify and solve problems that cause invalid options in their BSC and ARB projects.
