I would like to check the code hash of an account from within my smart contract. Is this possible?

I have since learned that this isn't possible, and could only be done using an external oracle or other off-chain service. If this changes in the future I will update this answer.


There's currently no WASM intrinsic to do that. However, Newdex keeps a list of all smart contracts for anyone to check on-chain. See here for more details


Update Actually, you don't have access to account_object from the contract.

You can use account.code_version.

See https://github.com/EOSIO/eos/blob/0f6695cb8d31e3d2f318d1720e9d9ad23e1ce80d/libraries/chain/eosio_contract.cpp#L151

From cleos do: cleos get code <accountName>

    The question asks how to do it from within a smart contract, not how to do it with cleos. Sep 24, 2018 at 15:42
