Install Weave

To get started, you need to first install our Weave CLI.
brew install initia-labs/tap/weave
2

Configure Weave and Gas Station Account

With Weave installed, you need to set up and fund your gas station account. This account will be used to fund the various bots and processes involved in the rollup’s operations.
weave init
This will prompt you to either generate a new account to use as your gas station account or import an existing account’s mnemonic. Once you have created your account, you then need to fund it with some INIT tokens (for OPinit bots bridging transactions) and TIA (for submitting data to Celestia).
3

Deploy the Rollup

Now that you have configured your gas station account, you can proceed to deploy your rollup.
weave rollup launch
From the provided options, you can:
  • Select your VM
  • Choose your Chain ID and default gas token denomination
  • Choose your DA layer
  • Enable the price oracle
  • Set genesis accounts
If you want more information about a specific option, access the tooltip by pressing ctrl+T. And if you want to go back to the previous step, press ctrl+Z.
To ensure that you have tokens available to send transactions on your rollup, you should add at least 1 address you control to the list of genesis accounts when prompted.
Once you have selected all the options, Weave will automatically start the rollup. When everything is complete, you will see the rollup’s endpoint information, which includes the REST, RPC, and, for EVM rollups, JSON-RPC endpoints. The CLI will also create a magic link that you can use to add your rollup to InitiaScan.
# Example output
Rollup Endpoints:
• REST API: http://localhost:1317
• RPC: http://localhost:26657
• RPC-WS: ws://localhost:26657/websocket
• gRPC: http://localhost:9090

We recommend opening this in Chrome because some browsers may not support localhost access from a different host, or you can edit your browser's settings to allow it if necessary.
At this point, you can now interact with your rollup, send transactions, and deploy contracts on the rollup. However, for full functionality, you will also need to run the OPinit Executor and Challenger bots as well as the IBC Relayer.
At this stage, you can interact with your rollup and deploy contracts, as well as send transactions. However, to enable bridging INIT and other tokens from L1, setting up DA, and more, you will also need to run the OPinit Executor, Challenger bots, and the IBC Relayer. To do this, follow the steps below.
4

Start the OPinit Executor

The OPinit Executor bot is responsible for executing INIT bridging transactions between the Initia L1 and your rollup, submitting the rollup state output to the L1, submitting DA data to Celestia, and more. To start the bot, run
weave opinit init
This will prompt you to set up the bot’s configuration through a series of questions.
✓ Existing keys in /Users/tansawit/.minitia/artifacts/config.json detected. Would you like to add these to the keyring before proceeding? > Yes, use detected keys
✓ Which bot would you like to run? > Executor
✓ Please select an option for the system key for Oracle Bridge Executor > Generate new system key
✓ Existing /Users/tansawit/.minitia/artifacts/config.json detected. Would you like to use the data in this file to pre-fill some fields? > Yes, prefill
✓ Specify listen address of the bot ... localhost:3000
✓ Specify L1 RPC endpoint ... https://rpc.testnet.initia.xyz:443/
✓ Specify rollup chain ID ... demo-314
✓ Specify rollup RPC endpoint ... http://localhost:26657
✓ Specify rollup gas denom ... umin
✓ OPInit bot setup successfully. Config file is saved at /Users/tansawit/.opinit/executor.json. Feel free to modify it as needed.
✓ You can start the bot by running `weave opinit start executor`
Once all of that is complete, you can start the bot by running the following command.
weave opinit start executor
You should see the bot running in the terminal.

Start the OPinit Challenger

For production use, we recommend setting up the Challenger bot on a separate machine from the Executor bot.
The OPinit Challenger bot is responsible for monitoring the Executor bot’s output proposal and ensuring its validity. To start the bot, run
weave opinit init
Again, you’ll be guided through a series of questions similar to the Executor. The main difference is that you’ll be setting up the Challenger instead of the Executor.

If everything is working correctly, you will now have both the Executor and Challenger bots running.

Start the IBC Relayer

Finally, you need to set up the IBC Relayer bot. This bot relays IBC messages between the Initia L1 and your rollup. It is essential for oracle price updates and managing IBC bridging transactions, including compatibility with Minitswap.
weave relayer init
By default, Weave also allows you to set up the relayer for any whitelisted rollup. But in this case, we will be setting up the relayer for your local rollup.
✓ Select the type of Interwoven rollup you want to relay > Local Rollup (demo-314)
✓ L1 network is auto-detected > initiation-2
✓ Specify rollup RPC endpoint ... http://localhost:26657
✓ Specify rollup GRPC endpoint ... http://localhost:9090
✓ Specify rollup WebSocket endpoint ... ws://localhost:26657/websocket
✓ Select method to setup IBC channels for the relayer. > Subscribe to only `transfer` and `nft-transfer` IBC Channels (minimal setup)
✓ Select the IBC channels you would like to relay ... 2 IBC channels subscribed
✓ Do you want to setup relayer with the challenger key > Yes (recommended, open the tooltip to see the details)
✓ Relayer setup successfully. Config file is saved at /Users/tansawit/.hermes/config.toml. Feel free to modify it as needed.
✓ You can start the relayer by running `weave relayer start
Once all of that is complete, you can start the bot by running the following command.
weave relayer start
You should see the bot running in the terminal.
