# 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 one of the below addresses in order to have your transactions propagated though our network.

### Tip Address

```
svsMoWJBwLcs8JgfN8VaF111tAc199KpYeTKRwxRtip
```

## How it works

* User sends a sendTransaction request to one of the endpoints
* User transaction is then validated for completeness and tip existence
* 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
