devnet = "https://api.devnet.solana.com"
mempool_endpoint = "wss://api.mainnet-beta.solana.com"

[private_key]
# Your wallet private key (Base58 format)

[jito]
endpoint = "https://mainnet.block-engine.jito.wtf"
bundle_endpoint = "https://mainnet.block-engine.jito.wtf/api/v1/bundles"
tip_account = "96gYZGLnJYVFmbjzopPSU6QiEV5fGqZNyN9nmNhvrZU5"

[mev_strategies]
enabled_strategies = ["arbitrage", "front_run", "back_run", "liquidation"]
min_profit_threshold = 0.005  # 0.5% minimum profit

[arbitrage]
enabled_dexs = ["raydium", "orca", "serum", "aldrin"]
min_price_difference = 0.01   # 1% minimum price difference
max_slippage = 0.003          # 0.3% maximum slippage

[front_running]
max_priority_fee = 0.01       # Maximum priority fee in SOL

target_profit_margin = 0.02   # 2% target profit margin

[back_running]
follow_distance = 1           # Blocks to wait after target transaction
profit_threshold = 0.015      # 1.5% minimum profit threshold

[liquidation]
monitored_protocols = ["mango", "solend", "port"]
