# Lightspeed

The Lightspeed project is Solana Vibe Station's solution to landing transactions\
on the Solana blockchain as fast as possible. Lightspeed requires a tip\
instruction to a valid tip address in order to have your transactions propagated\
through our network. The minimum tip is 0.001 SOL (1,000,000 lamports).

### Tip Addresses

The standard Lightspeed tip address:

```
svsMoWJBwLcs8JgfN8VaF111tAc199KpYeTKRwxRtip
```

Public, constant, and always valid. This is the simplest option and requires no additional calls.

#### Stealth tipping

Lightspeed can also issue a dynamically generated tip address for you to use in place of the standard one. Because the standard address is public and constant, anyone watching the chain can identify a transaction as Lightspeed traffic just by seeing a transfer to it. A dynamically generated address carries no such marker, so your transaction does not advertise the route it took.

Tips sent to a dynamically generated address remain in that address until its expiry time has passed.

Stealth tipping is optional. Transactions are validated and routed identically whichever address type they tip — the only difference is what an outside observer can infer.

### How it works

* User sends a sendTransaction request to one of the endpoints
* User transaction is then validated for completeness and tip existence, against either the standard tip address or a valid dynamically generated one
* Lightspeed engine forwards to appropriate upstream peers based on tip amount and route specified by user
* User transaction then races among multiple different routes to be processed by leader validator
