File Update Behavior

Update Frequency

All files update according to update_interval in config.toml:

update_interval = 10000  # Updates every 10 seconds

Atomic Updates

Files are written atomically:

Write to temporary file
Validate contents
Rename to final filename
Old file is replaced

File Permissions

Generated files have permissions:

Owner: Read/Write (644)
Group: Read
Others: Read

File Locations

Files are created in the current working directory:

./smb-config.toml         # SMB mode
./notarb-config.toml      # NotArb mode
./markets.json            # NotArb mode
./lookup-tables.json      # NotArb mode
./notarb-attributes.json  # NotArb mode

Dummy Configurations

When no mints meet filter criteria, dummy configs are generated:

SMB Dummy Config

[[routing.mint_config_list]]
mint = "11111111111111111111111111111111"
pump_pool_list = []
lookup_table_accounts = []
process_delay = 1000000000

[spam]
enabled = false

[jito]
enabled = false

NotArb Dummy Markets

{
    "groups": [[]],
    "update_timestamp": 1753221082643
}

Custom Output Names

Configure custom output filenames:

output = "my-custom-name"

Results in:

my-custom-name.toml (SMB mode)
my-custom-name.json (NotArb mode)

File Server Endpoints

When file server is enabled (port > 0), files are available via HTTP:

Version Compatibility

SMB Compatibility

Version 0.11.5+: Full support
Older versions: Not supported

NotArb Compatibility

Latest GitHub release: Full support
Older versions: Check changelog

Validation

SMB Validation

TOML syntax must be valid
All pool addresses must be valid base58
Mint addresses must be valid SPL tokens
Compute limits within Solana bounds

NotArb Validation

JSON syntax must be valid
Market addresses must be valid
All numeric values within expected ranges
Required fields present

Error Handling

Malformed Output

If output generation fails:

Previous valid config retained
Error logged
Retry on next interval

Partial Updates

If some data unavailable:

Use cached values
Generate partial config
Log missing data

Best Practices

Monitor File Updates: Check timestamps to ensure fresh data
Validate Before Use: Bot should validate config before trading
Keep Backups: Maintain last known good configuration
Watch File Sizes: Large configs may indicate issues
Check Dummy Values: Presence indicates no opportunities found
