Installing the CLI
Setting up a vulnerable contract
Deploying a Trap on testnet
Connecting an operator to the Trap

Recommended System Requirements

2 CPU Cores
4 GB RAM
20 GB Disk Space

Trap Setup

1. Configure Enviorments

Drosera CLI:

curl -L https://app.drosera.io/install | bash

source /root/.bashrc

droseraup

Foundry CLI:

curl -L https://foundry.paradigm.xyz | bash

source /root/.bashrc

foundryup

Bun:

curl -fsSL https://bun.sh/install | bash

2. Deploy Contract & Trap

mkdir my-drosera-trap

cd my-drosera-trap

Replace Github_Email & Github_Username:

git config --global user.email "Github_Email"
git config --global user.name "Github_Username"

Initialize Trap:

forge init -t drosera-network/trap-foundry-template

Compile Trap:

curl -fsSL https://bun.sh/install | bash
bun install

forge build

skip warnings!

Deploy Trap:

DROSERA_PRIVATE_KEY=xxx drosera apply

Replace xxx with your EVM wallet privatekey (Ensure it's funded with Holesky ETH)
Enter the commamd, when prompted, write ofc and press Enter.

3. Check Trap in Dashboard

1- Connect your Drosera EVM wallet: https://app.drosera.io/

2- Click on Traps Owned to see your deployed Traps OR search your Trap address.

4. Bloom Boost Trap

Open your Trap on Dashboard and Click on Send Bloom Boost and deposit some Holesky ETH on it.

5. Fetch Blocks

drosera dryrun

Operator Setup

1. Whitelist Your Operator

1- Edit Trap configuration:

cd my-drosera-trap
nano drosera.toml

Add the following codes at the bottom of drosera.toml:

private_trap = true
whitelist = ["Operator_Address"]

Replace Operator_Address with your EVM wallet Public Address between " " symbols
Your Public Address is your Operator_Address.

2- Update Trap Configuration:

DROSERA_PRIVATE_KEY=xxx drosera apply

Replace xxx with your EVM wallet privatekey

Your Trap should be private now with your operator address whitelisted internally.

2. Operator CLI

cd ~

# Download
curl -LO https://github.com/drosera-network/releases/releases/download/v1.16.2/drosera-operator-v1.16.2-x86_64-unknown-linux-gnu.tar.gz

# Install
tar -xvf drosera-operator-v1.16.2-x86_64-unknown-linux-gnu.tar.gz

Test the CLI with ./drosera-operator --version to verify it's working.

# Check version
./drosera-operator --version

# Move path to run it globally
sudo cp drosera-operator /usr/bin

# Check if it is working
drosera-operator

3. Install Docker image

docker pull ghcr.io/drosera-network/drosera-operator:latest

4. Register Operator

drosera-operator register --eth-rpc-url https://ethereum-holesky-rpc.publicnode.com --eth-private-key PV_KEY

Replace PV_KEY with your Drosera EVM privatekey. We use the same wallet as our trap wallet.

5. Open Ports

# Enable firewall
sudo ufw allow ssh
sudo ufw allow 22
sudo ufw enable

# Allow Drosera ports
sudo ufw allow 31313/tcp
sudo ufw allow 31314/tcp

6. Install & Run Operator

Choose one Installation Method:

Method 1: Install using Docker
Method 2: Install using SystemD

Method 1: Docker

6-1-1: Configure Docker

Make sure you have installed Docker in Dependecies step.

If you are currently running via old systemd method, stop it:

sudo systemctl stop drosera
sudo systemctl disable drosera

git clone https://github.com/0xmoei/Drosera-Network

cd Drosera-Network

cp .env.example .env

Edit .env file.

nano .env

Replace your_evm_private_key and your_vps_public_ip

6-1-2: Run Operator

docker compose up -d

6-1-3: Check health

cd Drosera-Network
docker compose logs -f

No problem if you are receiveing WARN drosera_services::network::service: Failed to gossip message: InsufficientPeers

6-1-4: Optional Docker commands

# Stop node
cd Drosera-Network
docker compose down -v

# Restart node
cd Drosera-Network
docker compose up -d

Now running your node using Docker, you can Jump to step 7.

Method 2: SystemD

6-2-1: Configure SystemD service file

Enter this command in the terminal, But first replace:

PV_KEY with your privatekey
VPS_IP with your solid vps IP (without anything else)
if using a local system, then replace vps ip with 0.0.0.0

sudo tee /etc/systemd/system/drosera.service > /dev/null <<EOF
[Unit]
Description=drosera node service
After=network-online.target

[Service]
User=$USER
Restart=always
RestartSec=15
LimitNOFILE=65535
ExecStart=$(which drosera-operator) node --db-file-path $HOME/.drosera.db --network-p2p-port 31313 --server-port 31314 \
    --eth-rpc-url https://ethereum-holesky-rpc.publicnode.com \
    --eth-backup-rpc-url https://1rpc.io/holesky \
    --drosera-address 0xea08f7d533C2b9A62F40D5326214f39a8E3A32F8 \
    --eth-private-key PV_KEY \
    --listen-address 0.0.0.0 \
    --network-external-p2p-address VPS_IP \
    --disable-dnr-confirmation true

[Install]
WantedBy=multi-user.target
EOF

6-2-2: Run Operator

# reload systemd
sudo systemctl daemon-reload
sudo systemctl enable drosera

# start systemd
sudo systemctl start drosera

6-2-3: Check Node Health

journalctl -u drosera.service -f

!! No problem if you are receiveing WARN drosera_services::network::service: Failed to gossip message: InsufficientPeers

6-2-4: Optional commands

# Stop node
sudo systemctl stop drosera

# Restart node
sudo systemctl restart drosera

Now running your node using `SystemD`, you can Jump to step 7.

7. Opt-in Trap

In the dashboard., Click on Opti in to connect your operator to the Trap

8. Check Node Liveness

Your node will start producing greeen blocks in the dashboard
