Where is the ERC 20 token code?

Question

I've read about and understand the idea behind the ERC20 Token Standard, but is there an official contract people can download and use? Or is it an official list of functions a smart contract should include in order to be up to standard?

Anyone know where I can find a polished and ready to go version of ERC20? I first read about it here: https://github.com/ethereum/EIPs/issues/20 And I also looked at this: https://theethereum.wiki/w/index.php/ERC20_Token_Standard

Or am I missing something super obvious?

Check out OpenZeppelin's implementation of a standard ERC20 token for an example that follows best security practices. — arseniy, May 04 '17 at 13:11
Yes, it is an agreed upon list of functions + events a smart contract must include to meet the standard. See the answer by Eth to this question: https://ethereum.stackexchange.com/questions/16714/what-are-the-key-criteria-for-meeting-the-erc20-token-standard. In the comments, we asked if there was an official list somewhere. So far, it seems like the Ethereum wiki and the github threads are the only 2 places that list these 6 functions + 2 events that make up the ERC20 standard, and the specific words in which they need to be written. For instance: "TotalSupply" not "TotalCoinSupply" — Tesa, May 29 '17 at 09:16

The ERC20 standard defines an interface, which is the name of the functions as well as their signature. Signature means a list of their arguments. It also defines what these functions should do. But it does not define how you implement it and thus it does not include any code.

For some suggested implementations, have a look at this GitHub repo: https://github.com/ConsenSys/Tokens

If that's your real name, you have the coolest name ever. – Sentinel May 04 '17 at 13:52

"It also defines what these functions should do." < This feels confusing to me, I think what Thorkil meant to say here is that "It also defines what each function returns". So basically it says, if you want to call yourself an ERC-20 you have to offer these functions that return these types of things. Other than that, do what you want! – Todd Vance Jan 22 '18 at 21:28
