Step 1

First, if you don't have a wallet yet, you can download and install the MetaMask extension to your browser. Proceed to setup the wallet.

Do not give your seed phrase to anyone! Keep it safe!





Step 2

Next, we need to claim some test ETH on Sepolia, Arbitrum Sepolia, Blast Sepolia & Mode Sepolia.

You can use the faucets below to get ETH on these networks,

Google Cloud Web3 Faucet (Sepolia): cloud.google.com

QuickNode Faucet (Arbitrum Sepolia): faucet.quicknode.com/arbitrum/sepolia

QuickNode Faucet (Blast Sepolia): faucet.quicknode.com/blast/sepolia

QuickNode Faucet (OP Sepolia): faucet.quicknode.com/optimism/sepolia







Step 3

Next, head over to Brid.gg and connect your wallet.

Now bridge some ETH from Sepolia to Base Sepolia.

Press "Review Transaction" & confirm the transaction with your wallet.

Keep a small amount of ETH on Sepolia for gas fees.




Step 4

Now head over to T3rn Bridge & connect your wallet.

Set the "From" as Base Sepolia and set "To" as any network of your choice, then input an amount that's over the minimum required amount.

Now press "Confirm Transaction" & confirm with your wallet.

- Each transaction will earn you 1 BRN, So try to perform as many bridges between the different networks as you can.

- If you don't have enough ETH on Sepolia for gas fees, you can run this miner for a few minutes to get some more: sepolia-faucet.pk910.de/#/
