Supported Bots

arb-assist currently supports two major Solana arbitrage bot implementations, each with its own configuration format and features.

SolanaMevBot On-Chain (SMB)

Overview

SolanaMevBot On-Chain is a high-performance arbitrage bot that executes trades directly on the Solana blockchain. arb-assist generates TOML configuration files optimized for SMB's requirements.

Key Features

• Flash Loan Support: Borrow capital for arbitrage without upfront liquidity

• Multi-mint Merging: Combine multiple arbitrage opportunities in single transactions

• Jito Bundle Integration: Submit transactions through Jito for MEV protection

• Spam Mode: Rapid transaction submission for competitive markets

Configuration Output

When mode = "smb" or mode = "both", arb-assist generates:

• smb-config.toml: Complete bot configuration

• Dynamic updates every 10 seconds (configurable)

• Automatic bot activation/deactivation

Example Configuration Structure

[bot]
merge_mints = true
compute_unit_limit = 600_000

[[routing.mint_config_list]]
mint = "TokenMintAddress..."
pump_pool_list = ["PoolAddress1..."]
meteora_dlmm_pool_list = ["PoolAddress2..."]
lookup_table_accounts = ["ALUTAddress..."]
process_delay = 400

[spam]
enabled = true
compute_unit_price = { strategy = "Random", from = 10000, to = 50000 }

[jito]
enabled = true
tip = { strategy = "Random", from = 3000, to = 12000 }

NotArb onchain-bot

Overview

NotArb is a Java-based arbitrage bot with advanced features for high-frequency trading. arb-assist generates JSON configuration files and supporting data files for NotArb.

Key Features

• JVM Optimization: Leverages Java's performance capabilities

• Protected Keypairs: Enhanced security for private keys

• Multi-region Jito: Submit to multiple Jito endpoints

• Dynamic Threading: Adaptive thread pool management

Configuration Output

When mode = "na" or mode = "both", arb-assist generates:

• notarb-config.toml: Main configuration file

• markets.json: 2D array of market addresses

• lookup-tables.json: Array of lookup table addresses

• notarb-attributes.json: Dynamic fees and settings

Example Output Files

notarb-config.toml:

{
  "jvm_args": ["-server", "-Xmx8192m"],
  "keypair_path": "${DEFAULT_KEYPAIR_PATH}",
  "flash_loan": true,
  "max_lookup_tables": 10
}

markets.json:

{
  "groups": [
    [
      "Market1Address...",
      "Market2Address..."
    ]
  ],
  "update_timestamp": 1753221082643
}

notarb-attributes.json:

{
  "cu_limit": 320002,
  "jito_enabled": true,
  "jito_min_tip": 28305,
  "jito_max_tip": 60000,
  "spam_enabled": true,
  "spam_min_fee": 11385,
  "spam_max_fee": 32000
}

Choosing the Right Bot

Use SMB-Onchain if you:

• Want the fastest possible execution

• Have limited server resources

• Prefer Rust-based tools

• Need mint merging capabilities

Use NotArb if you:

• Want JVM-based performance tuning

• Need multi-region Jito submission

• Prefer Java ecosystem tools

• Require advanced threading control

Running Both Bots

arb-assist supports generating configurations for both bots simultaneously:

mode = "both"  # Generates configs for both SMB and NotArb

This allows you to:

• Test both implementations

• Use different bots for different strategies

• Maximize arbitrage coverage

• Compare performance

Future Support

arb-assist is designed to be extensible. Future versions may support additional arbitrage bots. The modular architecture allows for easy integration of new bot types.
