Configure Settings

1. Go to Settings and set your preferred Network Environment - Testnet.

2. Enable your preferred networks to operate on by checking your selections.

If your wallet balance falls below the threshold on one of your enabled networks, that specific network will be removed.

Optional: Configure Your Network RPC URLs

Click configure your network RPC URLs and add RPC URLs for each enabled network, or skip this step and automatically use the default RPC URLs.

Configure Your Arbitrage Strategies

Click configure your arbitrage strategies, and expand for each network and asset to add your own strategies.

There are 5 fields for each asset.

1. Minimum Profit per Order

  • Specify the lowest acceptable profit that your executor should aim for when bidding on orders.

2. Minimum Profit Rate

  • Determine the lowest acceptable profit rate, as a percentage, for your executor when bidding on orders. This rate helps assess the profitability of an order relative to its size.

3. Maximum Amount per Order

  • Indicate the highest amount your executor is allowed to bid for a single order.

4. Minimum Amount per Order

  • Establish the smallest amount your executor should consider when bidding on orders.

5. Maximum Share of my Balance per Order

  • Specify the highest percentage of your total balance that your executor can allocate to a single order.

6. Save strategy
