DOP Trap

The drosera.toml file is configured to deploy a simple DOP trap. Ensure the drosera.toml file is set to the following configuration:

# Contract function will be executed when the trap is triggered
response_contract = "0xF9F26c467b13A4f805DAB58c0203CAc82bf8A753"
response_function = "responseCallback(uint256)"

To deploy the trap, run the following commands:

# Compile the Trap
forge build

# Deploy/Update the Trap
# Use the account whitelisted for use on the Drosera Holesky testnet.
DROSERA_PRIVATE_KEY=0x.. drosera apply

Note: The DROSERA_PRIVATE_KEY environment variable can be used to deploy traps. You can also set it in the drosera.toml file as private_key = "0x..".

After successfully deploying the trap, the CLI will add an address field to the drosera.toml file.

Congratulations! You have successfully deployed a trap!
