# Base

Coinbase's Ethereum L2 — dual-venue Uniswap v2 + v3, native ETH gas.

Base is Coinbase's Ethereum L2. It uses native **ETH** for gas and trading, and is one of Novamp's dual-venue chains.

{% hint style="info" %}
💡 `🔵 Base` supports both Uniswap versions: zero-fee tokens launch on **v3**, and fee-on-transfer tax tokens launch on **v2**.
{% endhint %}

## How it works

Base supports both Uniswap versions, so Novamp routes each launch automatically:

| Token type                                      | Venue      | Contract                                  |
| ----------------------------------------------- | ---------- | ----------------------------------------- |
| **Zero-fee token**                              | Uniswap v3 | `NovampToken` seeded by the `V3Seeder`    |
| **Tax token** (fee-on-transfer, 0–10% buy/sell) | Uniswap v2 | `NovampTaxToken` seeded by the `V2Seeder` |

Either way the token trades on a real pool from birth, with the same guardrails (creator allocation + lock, anti-snipe presets, optional early-sell fee, liquidity lock/burn, optional atomic initial buy).

## How to use it

Connect an embedded or external EVM wallet, [switch to Base](/getting-started/switch-networks.md), and keep a little ETH for gas. Then discover and trade, or launch a zero-fee or tax token.

| Contracts    | Full verified Base set in [Contracts & addresses](/protocol/contracts-and-addresses.md); infrastructure Basescan-verified, tokens (v2 and v3) auto-verify via matching bytecode |

## What happens next?

Once you're on Base with ETH for gas, browse [Discover](/traders/discover.md) or launch a zero-fee or tax token.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.novamp.io/getting-started/chain-guides/base.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
