Build your first app on Optimism!
This documentation is deprecated. Please use our new technical documentation.
in readme
the step below
git clone [email protected]:ethereum-optimism/optimism.git
cd optimism
yarn
yarn build
docker-compose build # need to specify the compose file or just cd ops dir
docker-compose up
In README we have a bit
Ethereum are required to replace certain EVM opcodes with custom behavior.
What would be the source material for this to know what actually happens here? Would be nice to link from README, so the reader does not need to guess.
Describe the bug
I get an error when I docker-compose up.
It seems to be a versioning issue, is there a solution?
output is

No error and working fine.
Is your feature request related to a problem? Please describe.
It takes a long time to do the docker-compose build step, as you acknowledge in the doc:
Now we just need to download, build, and install our Optimistic Ethereum node by running the following commands. Please note that docker-compose build will take a while. We're working on improving this (sorry)!
Describe the solution you'd like
Put a docker image on a registry.
I noticed there are a couple of broken links in the optimism-tutorial repo that needs to be fixed.
I followed the instructions to create a local Optimism network. Basically, I checked out the Optimism monorepo and ran the the following under the ops folder:
docker-compose up -d
I connected to the L1 hardhat network and saw the default 20 accounts (each with 5000ETH). I created a smart contract on the L1 network by connecting to port 9454 directly. Things worked all fine with the L1 network.
However, when I tried to create a smart contract on the L2geth network, I ran into the following error:
reason: 'insufficient funds for intrinsic transaction cost',
code: 'INSUFFICIENT_FUNDS',
error: ProviderError: invalid transaction: insufficient funds for gas * price + value
at HttpProvider.request (/Users/jou2019/workspace/hello-world/node_modules/hardhat/src/internal/core/providers/http.ts:74:19)
at GanacheGasMultiplierProvider.request (/Users/jou2019/workspace/hello-world/node_modules/hardhat/src/internal/core/providers/gas-providers.ts:312:34)
at processTicksAndRejections (node:internal/process/task_queues:96:5),
method: 'sendTransaction',
When I looked at the accounts and fund of the L2geth network, I saw a single account there (0x00000398232e2064f896018496b4b44b3d62751f in my case) with 0ETH.
Not sure if that is a bug or not. The instructions seem to indicate the 20 L1 test accounts should be created for both L1 and L2 with funds. Or maybe that single account with 0 fund is expected. I cannot find instructions how to move forward to "create" fund myself on the L2 network. Wonder if anyone can give me some help on how to move forward. Thanks a lot in advance.
I am unable to run the x-chain tests, getting this error:
1) Layer 1 <> Layer 2 ERC20 Transfers
"before each" hook for "should do the full flow":

yarn compile
yarn test
This is an issue because l2ethers.contracts is undefined. Was it refactored somewhere?
when run
crossChainMessenger = new optimismSDK.CrossChainMessenger({ l1ChainId: 42, // For Kovan, it's 1 for Mainnet l1SignerOrProvider: l1Signer, l2SignerOrProvider: l2Signer, });
throw

Hi team,
I am not able to understand that if the internal transaction is affecting the account balance of optimism? If yes, then how?
The tutorial points to optimismfaucet.xyz, that faucet does not exist anymore.
Describe the bug
That web page should direct to this tutorial.
To Reproduce
Expected behavior
I'd expect the link to lead to this tutorial.

Describe the bug
ETH balances for L2 accounts return zero balances when instantiated with either hardhat's default list of accounts, or the private keys of the local deployer and sequencer addresses.
To Reproduce
Steps to reproduce the behavior:
Expected behavior
We should have starting L2 ETH balances for accounts.
Screenshots
Additional context
This issue arose from several upgrades to Optimism repositories in use by optimism-integration.
Thus, the Waffle-ERC20-Example and Truffle-ERC20-Example repositories are also broken with this same bug.

Hello, been following this tutorial https://github.com/ethereum-optimism/optimism-tutorial and everything runs smoothly until the part where I have to run docker-compose build command inside ops folder. I also tried install the packages with yarn install --force , but without any result.
My yarn version is 1.10.1.
Attaching screenshot of the error I'm stuck at:
https://ibb.co/25qBxdz
As shown in the screenshot, the first errors appears at @eth-optimism/contracts package.
This link:
https://github.com/ethereum-optimism/optimism-tutorial/tree/main/l1-l2-deposit-withdrawal
in the readme is broken. It seems that directory no longer exists on main branch anymore.
I am not sure if its the correct channel please excuse me.
Hello Team,
I am Cyril Naves, a doctoral student of university cote d 'azur and I am working on blockchain consensus for private networks.
I would like to ask you some questions as part of my thesis work, please.
I am interested in building a private network with optimism. My questions are:
Can optimism be used to create private networks locally? If yes can you please point me to a tutorial?
Can smart contract be deployed on optimism local private network? If yes can you please point me to the tutorial please?
What is consensus supported by optimism it is Proof of work or Proof of Authority like in Ethereum?
Also can you let me know the TPS measured in optimistic ethereum if you had tested?
Thanks for your help,
Cyril
Is there a web3 python project that covers the same calls?
L2 => L1 transaction on miannet must wait 7 days and on Kovan it's 60s, on optimism local network it also should a short time.

Describe the bug
A clear and concise description of what the bug is.
Followed instructions in Step:1 of the The Official™ Optimism Tutorial https://github.com/ethereum-optimism/optimism-tutorial. Compiled Solidity into EVM bytecode without any issues and then moved onto compiling an Optimistic Ethereum contract with the command TARGET=ovm npx hardhat compile which throws an ERROR: 'TARGET' is not recognized as an internal or external command,operable program or batch file.
To Reproduce

Add any other context about the problem here.
Standard-Bridge-Standard-Token
Following the README, if you setup a script as standard-bridge-standard-token/scripts/deploy.js, then following through the tutorial then you can reach the end successfully.
Standard-Bridge-Custom-Token
Following the README, if you setup a script as standard-bridge-custom-token/scripts/deploy.js, then following through the tutorial you encounter an HttpProvider error because the .env variables are not getting loaded in until you add require('dotenv').config() to the top of the file.
We should standardize this process and make it not work in either tutorial until adding require('dotenv').config() or have both tutorials automatically inject it (exactly how it works in standard-bridge-standard-token).
I am not sure of the solution, therefore I am making an issue. However, going to investigate to see if I can inject it into standard-bridge-custom-token, given the time.
In a recent commit docker-compose-nobuild.yml was removed so the instruction on running a local node don't work.
change
docker-compose -f docker-compose-nobuild.yml up -t 3600
to
docker-compose -f docker-compose.yml up -t 3600
in tutorials README, at "Start an Optimistic Ethereum Node" paragraph.
following the tutorial, on testing you get

Inspired by the hardhat and truffle tutorials, I believe that there should be a basic tutorial on how to get started with Dapptools for Optimism.
The watcher hasn't been maintained for months, switching over to core utils would be a better example for devs.
