#### 💻 Environment

Deployed and verified using remix

deployment link https://bscscan.com/address/0xda9c30737acb2ab72800e063e9ea792895d17df3 while it does show on sepolia https://sepolia.etherscan.io/tx/0x0562440256438ae77a6818474098fcdaa2a84f60610f7ea08fdd9099c24dcdd6

There may be an issue with your deployment. You can see that when reading as proxy https://bscscan.com/address/0xda9c30737acb2ab72800e063e9ea792895d17df3#readProxyContract , the name() and symbol() getters aren't working, but some other getters such as owner() work. I tried calling name() and symbol() from other tools such as Hardhat, but it gave an "execution reverted" error.

Also note that your implementation source code on bsc is different from your implementation on sepolia.

yes and it is deployed, as u can see in my previous transaction, I used the openzepplin contract wizard code, deployed and verified with remix, some more functions aren't working too, like eip712domain, I know nothing about hardhat, that's why I used remix plugin

I think this is caused by an incompatible EVM version being chosen in your Remix compilation settings resulting in opcodes that are not supported by the chain you are using.

The default EVM version in Remix is "Cancun", but BNB chain does not support Cancun yet. You would need to recompile with an older EVM version such as "Shanghai" and redeploy. See discussion in https://github.com/ethereum/solidity/issues/14972

I'm stuck, and they're both bscscan and openzepplin forum support not replying my query

do I have to deploy again?

I'll wait until bsc supports cacnun so I see
