# Tipping

## Overview

Every Nozomi transaction must include a tip — a standard Solana system transfer instruction to one of the Nozomi tip addresses. The minimum tip is **0.001 SOL**.

You only pay when your transaction lands. The tip is an instruction inside your transaction, so if the transaction fails, the tip is never charged. This means you can intentionally fail a transaction if, for example, you detect that someone else already captured the opportunity you were targeting.

## How Tips Are Used

| Delivery path      | What happens                             |
| ------------------ | ---------------------------------------- |
| Jito validator     | Entire tip is forwarded to Jito          |
| Harmonic bundles   | Tip is forwarded to Harmonic             |
| Staked connections | Tip pays for Nozomi's staked connections |

## Tip Priority

Nozomi queues transactions by tip amount — **higher tips land faster**. When multiple transactions compete for the same slot, the highest tipper wins.

## Compute Unit Price

The tip controls your priority within Nozomi's queue. Once Nozomi delivers your transaction to the Solana scheduler, the **compute unit price** determines its on-chain ordering.

Set your compute unit price to at least **1,000,000 micro-lamports** for competitive performance.

## Retries

Nozomi automatically retries your transaction until it is either confirmed or the blockhash expires. Higher-tipped transactions are retried more aggressively. You do not need to implement retry logic on your end.

## Tip Addresses

Send your tip to any one of the addresses below. **Rotate to a different random address for each transaction** — this avoids write lock contention on a single account and improves landing rates.

## Private Tip Addresses

For users who need dedicated tip addresses, Nozomi can generate private tip addresses that are exclusive to your project. These addresses are not shared with other users and provide additional isolation for your transactions.

Private tip addresses can be created from the Nozomi dashboard under the **Tip Accounts** page.

## Front-Running Protection

Nozomi offers a Front Running Protection mode that routes your transaction exclusively through a whitelist of trusted validators (Helius, Coinbase, etc.), preventing it from being seen by adversarial validators.

For additional protection on swaps:

* Set a strict slippage tolerance.
* Calculate and enforce `minAmountOut` in your transaction instructions.
