-One of Tanssi's core propositions for builders is that it provides Ethereum-grade economic security to every Tanssi-powered network, regardless of their TVL, userbase, or the specifics of the use case. Tanssi's design offers developers a shared security model, alleviating them from having to source enough economic security or negotiate with operators to run nodes opting-in for their networks.

In this model, different [vaults](/learn/tanssi/external-security-providers/symbiotic/#vaults){target=\_blank} associated with Tanssi provide economic security, and reliable operators can be allowed to provide their validation services to both, the vault and the Tanssi network.

+There are several ways to interact with the smart contract:
+
+1. Using the [Symbiotic CLI](https://github.com/symbioticfi/cli){target=\_blank}
+2. Using [Etherscan](https://etherscan.io/){target=\_blank}
+3. Using [Safe](https://safe.global/){target=\_blank} for multi-sig setups
+
+In any case, you'll need to sign the transaction using the account you intend to use for the node. You can choose between different options to do so:
+
+1. Using the account's private key directly (although this method is not recommended)
+2. Using a hot wallet, such as [Metamask](/builders/toolkit/ethereum-api/wallets/metamask/#install-the-metamask-extension){target=\_blank}
+3. Using a cold wallet, such as [ledger](https://www.ledger.com/){target=\_blank}
+
+The [following section](#setting-up-the-cli) outlines the steps for installing the Symbiotic CLI, if that's your method of preference.
+
+### Setting Up the Symbiotic CLI {: #setting-up-the-cli }
+
+The [Symbiotic CLI](https://github.com/symbioticfi/cli){target=\_blank} is a tool for interacting with Symbiotic's core smart contracts. It is written in [Python](https://www.python.org/){target=\_blank}, so you'll need to install the Python interpreter and [pip](https://pypi.org/project/pip/){target=\_blank}, Python's package installer:
+
+=== "Linux (Ubuntu/Debian)"
+
+    ```bash
+     sudo apt-get install python3 && \
+     sudo apt install python3-pip
+    ```
+
+=== "MacOS"
+
+    ```bash
+    brew install python3
+    ```
+
+Now, with Python installed, download the Symbiotic CLI and its dependencies:
+
+```bash
+git clone https://github.com/symbioticfi/cli.git && \
+cd cli && \
+pip3 install -r requirements.txt
+```
+
+Run the following command to check if the installation was successful:
+
+```bash
+python3 symb.py --help
+```
+
+The terminal should show a long list of the CLI available commands:
+
+<div id="termynal" data-termynal>
