Buffer V2 Trading (Mainnet Beta) is now LIVE on Arbitrum

Today we’re super excited to announce that binary options trading is now enabled on Buffer Arbitrum Mainnet.

Why Mainnet Beta?

Thank you to the 4,500+ traders who participated in the public testnet! The feedback you all shared was precious. Buffer’s goal is to provide a world-class exotic options trading experience, and this feedback has directly helped us move towards that.

Although critical feedback has been addressed, Buffer V2 mainnet beta is a new protocol built from the ground up, and we’re continuing to improve. To build trust in the protocol and ensure that Buffer is functioning as expected, we set up the following features to manage risks:

  • Trade size limit: Max trade size can be 2% of the available liquidity. For example, if the liquidity pool has 100,000 USDC of available liquidity, the max trade size can be 2000 USDC.
  • Max utilization of vault: Max vault utilization at a time is capped at 64% of the total available liquidity

The initial cap will help confirm Buffer’s security in a mainnet environment. Buffer is also undergoing a professional security audit to ensure the underlying code’s security robustness. We believe a gradual deployment through cap increases is the most secure way to establish confidence in the protocol.

Getting Started with Trading Simple Up/Down Options!

Below are instructions to help you get started.

Step 1 — Add Arbitrum network to your browser wallet

Connecting to Arbitrum on Metamask

Step 2 — Choose the asset to open a position.

Supported Assets:


Step 3 — Choose the expiration date on the binary option.

You can choose the expiration date from the “Select Duration” box present on the right-hand side of the dashboard. The expiration time determines the payout %, and it is possible to choose an expiration from 5 mins to 24 hours.

Step 4 — Choose the amount to invest.

You can choose your USDC investment amount from the dashboard’s box on the right-hand side.

For Buffer V2 binary option, the minimum investment starts at 1 USDC. The investment amount will be deducted from your balance and returned with a profit if your position closes in the money (correct estimation of price movement). If the position closes in loss (an incorrect assessment of price movement), the investment amount will not be returned.

Advanced Features Enabled for Buffer Traders:

You will now find a new setting on the right-hand side of the Investment tab. Clicking on this wheel will unlock two new features:

  • Slippage tolerance: Slippage tolerance indicates the maximum acceptable difference you allow to get the transaction fulfilled;
  • Partial fill: Enabling this feature will partially fill your trade rather than being canceled in case of insufficient funds in the “write” pool.

Step 5 — Approve the transaction to open a position

Once you click the approve button, a pop-up will appear asking you to approve the transaction. You can keep default approval for all selected to remove this step from your future interactions.

Step 6 — Choose the direction — 🔺Up or 🔻Down.

Once you have decided on the expiration and investment, you need to determine whether the asset’s price will grow or fall. Once you have made the decision, you are ready to open a trade. Once a position is opened, you will need to wait until the end of the expiration time to receive the result.
