Installation

Aztec Network Testnet

You need to have your own sepolia RPC or rent it from any paid provider, the free one will have limited access and can't be used.

1. Follow This Step If It's Your First Time Running Aztec Sequencer (Otherwise Just Next To Step 2):

sudo apt-get update && sudo apt-get upgrade -y

sudo apt install curl iptables build-essential git wget lz4 jq make gcc nano automake autoconf tmux htop nvme-cli libgbm1 pkg-config libssl-dev libleveldb-dev tar clang bsdmainutils ncdu unzip libleveldb-dev screen  -y

source <(wget -O - https://raw.githubusercontent.com/frianowzki/installer/main/docker.sh)

sudo groupadd docker && sudo usermod -aG docker $(whoami) && newgrp docker

bash -i <(curl -s https://install.aztec.network)

echo 'export PATH=$PATH:/root/.aztec/bin' >> ~/.bashrc

source ~/.bashrc

aztec-up alpha-testnet

2. Stop, Remove & Update Current Sequencer:

docker ps -a

docker stop [aztec-container-id] && docker rm [aztec-container-id]

rm -rf .aztec/alpha-testnet/data

aztec-up alpha-testnet

// OR use below if you need specific version (example: v0.87.2)
aztec-up -v 0.87.2

12. Now let's run Aztec Sequencer again if there is no error:

aztec start --node --archiver --sequencer \
  --network alpha-testnet \
  --l1-rpc-urls RPC_URL  \
  --l1-consensus-host-urls CONSENSUS_HOST_URL \
  --sequencer.validatorPrivateKey 0xPrivateKey \
  --sequencer.coinbase 0xPublicAddress \
  --p2p.p2pIp IP \
  --port 8081 

• Change RPC_URL with:

https://Your_Rented_RPC_URL

// OR

http://YourOWN_RPC_IP:PORT

• Change CONSENSUS_HOST_URL with:

https://Your_Rented_Beacon_RPC_URL

// OR

http://YourOWN__BEACON_RPC_IP:PORT

• Enter and wait until it fully synced, you can check the logs using:

docker ps -a

docker logs -f [aztec-container-ID]

13. Update Aztec Governance (Only for Validators):

docker ps -a

docker stop [aztec-container-id] && docker rm [aztec-container-id]

rm -rf .aztec/alpha-testnet/data

aztec-up alpha-testnet

If you are using CLI you can just add this line

--sequencer.governanceProposerPayload 0x54F7fe24E349993b363A5Fa1bccdAe2589D5E5Ef

Or if you use Docker Compose you can use this on your .env

cd .aztec/alpha-testnet

nano .env

ETHEREUM_RPC_URL=http:/your_IP:8545
CONSENSUS_BEACON_URL=http:/your_IP:3500
VALIDATOR_PRIVATE_KEY=0xPrivateKey
COINBASE=0xPublicAddress
P2P_IP=your_IP
GOVERNANCE_PAYLOAD=0x54F7fe24E349993b363A5Fa1bccdAe2589D5E5Ef

Save it and set Docker Compose:

nano docker-compose.yml

services:
  aztec-node:
    container_name: aztec-sequencer
    image: aztecprotocol/aztec:alpha-testnet
    restart: unless-stopped
    environment:
      ETHEREUM_HOSTS: ${ETHEREUM_RPC_URL}
      L1_CONSENSUS_HOST_URLS: ${CONSENSUS_BEACON_URL}
      DATA_DIRECTORY: /data
      VALIDATOR_PRIVATE_KEY: ${VALIDATOR_PRIVATE_KEY}
      COINBASE: ${COINBASE}
      P2P_IP: ${P2P_IP}
      LOG_LEVEL: debug
      GOVERNANCE_PAYLOAD: ${GOVERNANCE_PAYLOAD}
    entrypoint: >
      sh -c "node --no-warnings /usr/src/yarn-project/aztec/dest/bin/index.js start \
      --network alpha-testnet \
      --node \
      --archiver \
      --sequencer \
      --sequencer.governanceProposerPayload ${GOVERNANCE_PAYLOAD}"
    ports:
      - 40400:40400/tcp
      - 40400:40400/udp
      - 8081:8081
    volumes:
      - /root/.aztec/alpha-testnet/data/:/data

Run it by use this command:

docker compose up -d
