How to connect to the app?

A quick 'getting started' guide for new users

Step 1: Setup Wallet

If you're new to DeFi, you will need to install and set up a non-custodial wallet, that allows you to directly connect and interact with the dApp. For the purpose of this guide, we will be using MetaMask as an example.
Follow this guide to install and set up your MetaMask wallet.

Step 2: ETH/MATIC for Gas

All transaction fees on Arbitrum are payable in ETH and all transactions on Polygon are payable in MATIC. You will need Arbitrum ETH/ Polygon MATIC in your wallet to start trading or liquidity provisioning on Buffer.
You can buy ETH/MATIC directly on Arbitrum using Uniswap(Arbitrum). Alternatively, if you hold ETH/MATIC on other networks, you can use cross-chain bridges to transfer ETH to Arbitrum or MATIC to Polygon.
You can use the following options for transferring ETH to Arbitrum or MATIC to Polygon:

Step 3: Connect to the dApp

Navigate to If you want to trade on Buffer, click on 'Trade', and if you want to provide liquidity to the USDC vault or stake your BFR tokens, then click on 'Earn Yield'
Click on the 'Connect' button on the top right-hand corner of the UI (if you’re on the “Trade” page, you can also click on the larger 'Connect Wallet' button on the lower right of the trading dashboard).
You can then select between different wallets - (MetaMask, Coin98, Trust Wallet, Wallet Connect, Rainbow, Ledger live, Omni, Imtoken). Select your wallet type and confirm.

Switching between networks

Once you’ve connected your wallet you will be connected to the Arbitrum network by default, if you want to interact on Buffer - Polygon, you can easily switch between the two networks on Buffer, by clicking on the network button on the top right-hand corner of the interface.
