Parameters

As you may have noticed, copychain never reads your private key. The tool relies on an external bot, which is the one that normally uses the ENCRYPTED_PRIVATE_KEY file.

my_pubkey

(required)

Your wallet pubkey address.

grpc_url

(required)

Your gRPC url.

grpc_token

default: None

Your gRPC token, if required by your provider.

grpc_type

default: yellowstone

Supports both yellowstone and thorstream gRPC.

grpc_light

default: false

Some gRPC providers block any subscription stream. Enabling this option should resolve the issue. Only enable it if you encounter an error message similar to this:

[2025-07-29T18:57:30.772Z ERROR] Geyser stream error: Status { code: InvalidArgument, message: "failed to create filter: Subscribe on full stream with any is not allowed, at least one filter required", source: None }

copy_pubkeys

default: []

Addresses of other wallets you want to copy. If empty, copy_all must be enabled.

copy_all

default: false

Copy (or monitor) every wallets.

Enabling this in run mode will copy all wallets. Not recommended unless you use it with automation or you know exactly what you’re doing.

---

[engine]

bot

(required)

Underlying engine to use: smb, notarb or copy . The later will use the same one as the copied wallet.

[engine.smb]

config

(required)

Full path to your initial SMB configuration file.

binary

default: ./smb-onchain

Full path to the smb-onchain binary file.

[engine.notarb]

config

(required)

Full path to your initial NotArb configuration file.

install_dir

default: .

Full path to the NotArb installation directory.

---

[sessions]

blacklisted_mints

default: []

A list of mint public key addresses on which sessions should never be started.

timeout

default: 5

Timeout in seconds after which this tool should stop copying a session. A higher value means the tool will continue sending transactions longer after the copied wallet has stopped. A value that’s too low may cause frequent "start/stop" session spam.

copy_jito_no_failure_only

default: true

When this option is enabled and Jito sending is active in your SMB config, the tool will only copy sessions where no_failure_mode = true. This is because Jito transactions with no_failure_mode = false only include successful instructions, making it very difficult for the tool to reliably track sessions without hitting timeouts.

fees_history_size

default: 40

Maximum number of past transactions to consider for Jito tips (or priority fees) calculation. Only used when the SMB tip strategy (or CU price strategy) is set to File. See here for more info.

---

[sending]

process_delay

default: 400

Same as SMB configuration process_delay for [[routing.mint_config_list]] .

The bot will send out a tx, wait for process_delay ms, then send again and repeat [...]

default_lookup_tables

default: []

Additional Address Lookup Tables (ALT, LUT, or ALUT) to include in each transaction. Even though this tool copies the ALTs used by other users, you can specify extra ALTs here.

This can be useful if you have your own ALT.

compute_units_limit

default: { source = "Copy" }

Compute units are set for each sent transaction using the following options:

• source :

  • Fixed : fixed compute units limit.

    • { source = "Fixed", value = 350_000 }

  • Copy : dynamically uses the same as the copied wallet.

• percentage : if you want 20% more compute units than the copied wallet, set this to 120 . Only used when source = "Copy".

  • { source = "Copy", percentage = 120 }

This configuration value affects only Compute Units, not CU prices. See below for automatic fees/tips configuration.

spam_compute_unit_price

default: { source = "Local" }

Available parameters are:

• source :

  • Local : uses the parameter defined in your bot configuration file.

  • Copy : automatically and dynamically adjusted based on copied wallets and fees_history_size. A strategy parameter (see detailed below) can be used to adjust your strategy.

  • Helius : uses Helius Priority Fee API (see more info below helius_fee_api).

• strategy: used when source = "Copy" . Defaults to Random. Can be:

  • Random, Linear, Exponential or ExponentialRandom : works the same as in SMB.

  • ExponentialRandomReverse : works the same as ExponentialRandom but biases numbers toward the higher end of the range instead of the lower end.

• count : number of transactions to send at once. Defaults to 1.

• percentage : adjusts the final amount. Default is 100, which effectively does nothing.

• minimum_lamports : minimum CU price in lamports. These are not compute unit prices. Defaults to 0. They will be used to compute priority fees (compute unit price x compute units requested) as shown on Solscan:

  

  2794 lamports in this case

• maximum_lamports : maximum CU price in lamports. These are not compute unit prices. Defaults to 1_000_000 , which is 0.001 SOL priority fees.

Here are some examples:

copy-config.toml

[...]

[sending]
spam_compute_unit_price = { source = "Copy" }

copy-config.toml

[...]

[sending]
spam_compute_unit_price = { source = "Copy", strategy = "Linear" }  # count defaults to 1

copy-config.toml

[...]

[sending]
spam_compute_unit_price = { source = "Local" } # uses your SMB configuration

jito_tip

default: { source = "Local" }

Same as spam_compute_unit_price, overrides [jito] tip_config.

Parameter source can be Local, Copy or Jito. When set to Jito, it uses the Jito Tip Floor API (see configuration details below jito_tip_api).

vendors_tip

default: { source = "Local" }

Same as spam_compute_unit_price, overrides each [sending_venders] tip_amount SMB configuration.

Parameter source can only be Local , Copy or Temporal.

vendors_compute_unit_price

default: { source = "Local" }

Same as Parameters, overrides each [sending_venders] compute_unit_price SMB configuration.

Parameter source can be Local, Copy or Helius. When set to Helius, it uses the Helius Priority Fee API (see configuration details below helius_fee_api).

jito_tip_api

default: None

• update_interval : in seconds. Defaults to 15.

• percentile : the percentile range to use. Can be a number (0-100) or ema50. Numbers are interpolated, so any value between 0 and 100 is valid. Defaults to { from = "ema50", to = "ema50" }.

Example:

copy-config.toml

[sending]
jito_tip = { source = "Jito" }

[sending.jito_tip_api]
percentile = { from = "ema50", to = 75 }

temporal_tip_api

default: None

• update_interval : in seconds. Defaults to 15.

• percentile : the percentile range to use. Must be a number in range [0, 100]. Numbers are interpolated, so any value between 0 and 100 is valid. Defaults to { from = 25, to = 50 }.

Example:

copy-config.toml

[sending]
vendors_tip = { source = "Temporal" }

[sending.temporal_tip_api]
percentile = { from = 25, to = 50 }

helius_fee_api

default: None

• api_keys : an array of Helius API keys. Requests will rotate between these to avoid rate limit, if needed.

• update_interval : in seconds. Default to 15.

• percentile : the percentile range to use, derived from Helius "low/medium/high/veryHigh" levels. Numbers are interpolated, so any value between 0 and 100 is valid. Default to { from = 50, to = 50} , which is equivalent to Helius medium level.

• lookback_slots : adjust the number of slots analyzed for fee estimation. See Helius documentation. Default to 150.

• account_keys : see Helius documentation. Default to SMB and NotArb programs address.

The account keys method provides a simpler alternative to transaction serialization when you need quick fee estimates or want to estimate fees before constructing the complete transaction.

Example:

copy-config.ctoml

[sending]
spam_compute_unit_price = { source = "Helius" }

[sending.helius_fee_api]
api_keys = ["xxx", "yyy"]
percentile = { from = 45, to = 55 }
