Hello @alexanderhawl , do you see any errors in browser console too?

[alexanderhawl]

just only revert. But I replay it in blocksec phalcon exploer, it says invalid opcode MCOPY.

Can you share error screenshot?

This might not be related to cancun VM as if I compile using Shanghai EVM version and deploy to Remix VM(Shanghai) method call still fails

Also, address(this).balance returns the ETH balance of contract not the token balance

I tried the code in foundry, the evm_version is shanghai, it also reverts.

I used blocksec phalcon to fork a eth mainnet, transaction always went well no matter the compiler is cancun or shanghai. But if I selected remix vm cancun or shanghai, it reverted.

Difficult to deduce what's wrong

[alexanderhawl]

I found the error reason, in the remix vm , the token address is not a contract, so the balanceOf function is error. the res variable is 0x. So the abi.decode revert. Thanks your response.

okay. That's great. Hope you can fix it now. Closing this.
