Error! Unable to generate Contract ByteCode and ABI
Found the following ContractName(s) in source code : Address , Context , IERC20 , IUniswapV2Factory , IUniswapV2Pair , IUniswapV2Router01 , IUniswapV2Router02 , Ownable , SafeMath , SooNMooN
But we were unable to locate a matching bytecode (err_code_2)
For troubleshooting, you can try compiling your source code with the Remix - Solidity IDE and check for exceptions

Hi, please format your code, and you can have a look at this tutorial: Format code in the forum - General / Meta - OpenZeppelin Community

As for verifying contracts, I think you can use the plugin truffle-flattener, and for more details, you can have a look at this topic: Verifying a contract inheriting from OpenZeppelin Contracts

And you should share your contract address and compiler version.

i just found the solution and my contract is verified .
for beptoken20 , solution is here Verify Contract on bscscan.com - Binance Chain Docs

Sorry, I am not familiar with the BSC-Chain, but glad to hear that.
