Which bot is better, SMB or NotArb?

It ultimately comes down to personal preference, as both have their pros and cons:

	SMB	NotArb
Easier to get started	☑️
3rd-party vendors	☑️ (full support)	✔️ (only FAST and Astralane)
USDC arbitrage	✔️ (3-hop)	☑️ (full support as base mint)
USD1 arbitrage	✔️ (3-hop)
Transactions optimization		☑️ (uses less CU)
Bot optimization	☑️ (faster to start, uses less machine resources)
More configurable		☑️

We recommend starting with SMB if you have to choose one.

Why is the output stuck? Nothing happens

You might see the output "stucked" like this for instance:

[INFO ] Starting copychain v0.2.0
[INFO ] License valid (7 days 21 hours left)
[INFO ] Monitoring [xxx]

There are two main reasons:

1. There is no activity on any wallet you are copying.

2. There are transactions occurring for one or more wallets you’re copying, but none of them meet the requirements to start a copy session:

   1. The copied wallet is sending with Jito using no_failure_mode = false and copy_jito_no_failure_only is set to true : due to how this tool works, it's strongly recommended not to set this to false

   2. The copied wallet is sending with Jito, but you have enabled = false in your [jito] SMB config section

   3. The copied wallet is sending with Spam, but you have enabled = false in your [spam] SMB config section and Parameters is set to false

How to be sure the bot is stopped?

You can run this command to make sure every processes are stopped:

pkill -ef -9 "copychain run"

I ran into an error

You forgot to change binary permission:

Subscribe on full stream with any is not allowed

[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 }

Transaction too large

error -32602: Invalid Request: ErrorObject { code: InvalidParams, message: "Invalid Request: base64 encoded too large", data: None } 

Transactions have capped size and throw errors if you they are higher. To reduce the size, you need to add Address Lookup Table (ALT) to the configuration entry Parameters.

Using nonces, sending with Vendors or using auto-unwrapper add additionnal accounts to your transactions and may result in this kind of error.

copy wallet not found for id XX

[2025-07-29T18:57:30.772Z ERROR] Internal error (1): copy wallet not found for id 154

Verify the absence of concurrent execution of other bots or separate CopyChain instances targeting the same wallet. Such redundancy may disrupt CopyChain's internal tracking methodology.
