In this Guide, we contribute to Drosera testnet by:
- Installing the CLI
- Setting up a vulnerable contract
- Deploying a Trap on testnet
- Connecting an operator to the Trap
- 2 CPU Cores
- 4 GB RAM
- 20 GB Disk Space

Deploy Trap:
DROSERA_PRIVATE_KEY=xxx drosera apply- Replace
xxxwith your EVM walletprivatekey(Ensure it's funded withHolesky ETH) - Enter the commamd, when prompted, write
ofcand press Enter.
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.
Open your Trap on Dashboard and Click on Send Bloom Boost and deposit some Holesky ETH on it.
drosera dryrun1- Edit Trap configuration:
cd my-drosera-trap
nano drosera.tomlAdd the following codes at the bottom of drosera.toml:
private_trap = true
whitelist = ["Operator_Address"]- Replace
Operator_Addresswith your EVM walletPublic Addressbetween " " symbols - Your
Public Addressis yourOperator_Address.
2- Update Trap Configuration:
DROSERA_PRIVATE_KEY=xxx drosera apply- Replace
xxxwith your EVM walletprivatekey
Your Trap should be private now with your operator address whitelisted internally.

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.gzTest 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# Optional: we don't install using docker
docker pull ghcr.io/drosera-network/drosera-operator:latest
drosera-operator register --eth-rpc-url https://ethereum-holesky-rpc.publicnode.com --eth-private-key PV_KEY- Replace
PV_KEYwith your Drosera EVMprivatekey. We use the same wallet as our trap wallet.
Enter this command in the terminal, But first replace:
PV_KEYwith yourprivatekeyVPS_IPwith your solid vps IP (without anything else)- if using a
localsystem, then replace vps ip withlocalhost
