Set up the Metamask browser extension and Stake

Open the Metamask settings, located in the drop-down (top-right menu options). Set the following property values:

• Network Name: Fleek Network Testnet

• RPC URL: https://rpc.testnet.fleek.network/rpc/v0

• Chain ID: 59330

• Currency symbol: tFLK

Before proceeding, make sure to have the Fleek Network selected as the metamask network. Once confirmed, visit the Faucet website

In the Faucet website, you have to click the Connect Wallet

Once Connect Wallet is ready, proceed to Mint tFLK and wait until the balance of the account in your Metamask increases. You need to have tFLK before proceeding. Be patient.

Once tFLK balance is available, click in the Stake button. You'll be required to provided the following details from your node:

• Node Public Key

• Consensus Public Key

• Server IP Address

You can get the details quickly by running the node details script in the terminal connected to your machine or server where the node is set up and running, as follows:

curl https://get.fleek.network/node_details | bash

Restart the service:

sudo systemctl daemon-reload && \
sudo systemctl enable lightning

sudo mkdir -p /var/log/lightning
sudo touch /var/log/lightning/output.log
sudo touch /var/log/lightning/diagnostic.log
sudo systemctl restart lightning.service
