How to Run a Aurora Node with the Aurora Protocol L3 Chain on Solana

This guide provides step-by-step instructions for running a Aurora node on your local machine.

---

Prerequisites

1. Docker: Install Docker and ensure it’s running on your machine.

2. System Requirements:

   • RAM: 8-16 GB

   • CPU: 2-4 cores

   • Storage: Varies depending on Aurora chain traffic over time.

3. Aurora Configuration Details: Obtain the following:

   • Parent chain RPC URL.

   • Chain information JSON.

   • Sequencer node URL (if applicable).

---

Step 1: Get the Docker Image

Download the latest Aurora node Docker image:

docker pull aurora/nitro-node:latest

---

Step 2: Create a Data Directory

Create a directory for persistent data:

mkdir -p /path/to/aurora-data
chmod -R 777 /path/to/flora-data

---

Step 3: Gather Required Parameters

1. Parent Chain RPC: Replace <Parent RPC URL> with the RPC endpoint of the parent chain.

   Copy

   --parent-chain.connection.url=<Parent RPC URL>

2. Child Chain Info JSON: Example JSON:

   [{
      "chain-id":10263,
      "parent-chain-id":421614,
      "chain-name":"conduit-orbit-deployer",
      "chain-config":{
         "chainId":10263,
         "homesteadBlock":0,
         "daoForkBlock":null,
         "daoForkSupport":true,
         "eip150Block":0,
         "eip150Hash":"0x0000000000000000000000000000000000000000000000000000000000000000",

         "petersburgBlock":0,
         "istanbulBlock":0,
         "muirGlacierBlock":0,
         "berlinBlock":0,
         "londonBlock":0,
         "clique":{"period":0,"epoch":0},
         "arbitrum":{
            "EnableArbOS":true,
            "AllowDebugPrecompiles":false,
            "DataAvailabilityCommittee":true,
            "InitialArbOSVersion":32,
            "InitialChainOwner":"0x39f15185A5db359BAEd62D7efA40C99f88f5Ed3d",
            "GenesisBlockNum":0
         }
      },
      "rollup":{
         "bridge":"0xA5A1E43f6a1D7F6aFc92516DA5B07A25C6f4D8E7",
         "inbox":"0x5eC840B65FA9b35539FC91938cBfDfEe78b3dCd0",
         "sequencer-inbox":"0xC030b2607B8b195b3F4A343123E8ad342dF8294c",
         "rollup":"0x2D4A586430dd38A05FE185715672b76A04e562b7",
         "validator-utils":"0x7a135bFC73FE67c1C32FA5C8048e2aF368708dBc",
         "validator-wallet-creator":"0xf16584F5f4Fbb692818c5a4C2e09CFf39C6F10F8",
         "deployed-at":110999521
      }
   }]

   Use this JSON with the --chain.info-json flag.

3. Chain Name: Set the name of the chain using --chain.name. Example:

   --chain.name="conduit-orbit-deployer"

4. Sequencer Endpoint: If running as a non-sequencer node, add:

   --execution.forwarding-target=<Sequencer RPC URL>

---

Step 4: Run the Node

Run the following Docker command:

docker run --rm -it \
-v /path/to/ndai-data:/home/user/.ndai\
-p 8547:8547 \
-p 8548:8548 \
ndai/nitro-node:latest \
--parent-chain.connection.url=<Parent RPC URL> \
--chain.info-json='[{"chain-id":10263,"parent-chain-id":421614,"chain-name":"conduit-orbit-deployer","chain-config":{"chainId":10263,"homesteadBlock":0,"daoForkBlock":null,"daoForkSupport":true,"eip150Block":0,"eip150Hash":"0x0000000000000000000000000000000000000000000000000000000000000000","eip155Block":0,"eip158Block":0,"byzantiumBlock":0,"constantinopleBlock":0,"petersburgBlock":0,"istanbulBlock":0,"muirGlacierBlock":0,"berlinBlock":0,"londonBlock":0,"clique":{"period":0,"epoch":0},"arbitrum":{"EnableArbOS":true,"AllowDebugPrecompiles":false,"DataAvailabilityCommittee":true,"InitialArbOSVersion":32,"InitialChainOwner":"0x39f15185A5db359BAEd62D7efA40C99f88f5Ed3d","GenesisBlockNum":0}},"rollup":{"bridge":"0xA5A1E43f6a1D7F6aFc92516DA5B07A25C6f4D8E7","inbox":"0x5eC840B65FA9b35539FC91938cBfDfEe78b3dCd0","sequencer-inbox":"0xC030b2607B8b195b3F4A343123E8ad342dF8294c","rollup":"0x2D4A586430dd38A05FE185715672b76A04e562b7","validator-utils":"0x7a135bFC73FE67c1C32FA5C8048e2aF368708dBc","validator-wallet-creator":"0xf16584F5f4Fbb692818c5a4C2e09CFf39C6F10F8","deployed-at":110999521}}]' \
--chain.name="conduit-orbit-deployer" \
--http.api=net,web3,eth \
--http.addr=0.0.0.0 \
--ws.port=8548 \
--ws.addr=0.0.0.0

---

Step 5: Verify Node Status

Check the logs to ensure the node is syncing:

docker logs -f <container_id>

---

Tips

• Persistent Data: Ensure /path/to/ndai-data exists for storing node data across restarts.

• Firewall Settings: Open ports 8547 (HTTP) and 8548 (WebSocket).

• Graceful Shutdown: Stop the node safely to save its state:

  Copy

  docker stop --time=300 $(docker ps -q)

You are now running a full Aurora node!
