# Uniswap V3 Base Launch > Launch a tax-free Base ERC-20 token on a full-range Uniswap V3 WETH pool with a selectable fee tier, staged launch buys, and starter strategies. - URL: https://docs.sumo.trade/launch-tokens/base-uniswap-v3-launch - Markdown: https://docs.sumo.trade/launch-tokens/base-uniswap-v3-launch.md - Docs index: https://docs.sumo.trade/llms.txt **Base Uniswap V3** deploys a tax-free Base ERC-20 launch token, creates a token/WETH Uniswap V3 pool at the fee tier you pick, mints a full-range liquidity position while public trading is still closed, runs launch-wallet buys, then opens public trading. Choose this launch method for a tax-free token on a Uniswap V3 pool. For launch taxes, wallet limits, or tax clog, see [Uniswap V2 Base Launch](/launch-tokens/base-uniswap-v2-launch); for your own LP fee and any quote token, see [Uniswap V4 Base Launch](/launch-tokens/base-uniswap-v4-launch). | | Base Uniswap V3 | | ------------------ | ------------------------------------------------------------------ | | **Pool type** | Uniswap V3 pool, token/WETH, fee tier 0.01%, 0.05%, 0.30% or 1.00% | | **Liquidity** | Full-range V3 position NFT owned by the dev wallet | | **Tax controls** | Not available - V3 launch tokens are tax-free | | **Bundle wallets** | Up to 200 | | **Holder cleanup** | Not available on Base | ![Base Uniswap V3 token launch buy setup](/images/base-uniswap-v3-launch-buy-setup.png) ## Prerequisites Before launching, make sure you have: 1. Token metadata ready: name, ticker, image, description, and social links 2. Total supply and token decimals 3. ETH on Base for deployment, pool setup, initial liquidity, launch buys, and gas buffers 4. A launch plan: target supply control, pool-token percentage, pool fee tier, and bundle wallet count 5. A wallet plan: use ready wallets from private keys, [Wallet Farm](/wallet-farm/overview), or another profile, or create new Base wallets / buy aged Base wallets through [Wallet Marketplace](/wallets/wallet-marketplace) during the wizard > **Base WETH Quote** > > Base Uniswap V3 launches use WETH as the quote token. Operators enter ETH amounts in the wizard; Sumo stores WETH quote metadata on the active profile. ## Launch Flow ### 1. Info Choose **Base Uniswap V3** in the Launchpad field, then enter the token and profile details. | Field | Required | Description | | ------------------------ | -------- | ----------------------------------------------------------------------------- | | **Launchpad** | Yes | Select **Base Uniswap V3**. The launchpad is locked after the draft is saved. | | **Profile Name** | Yes | Internal Sumo profile name used after launch | | **Token Name** | Yes | ERC-20 token name | | **Ticker** | Yes | ERC-20 token symbol, auto-uppercased | | **Total Supply** | Yes | ERC-20 total supply before decimals | | **Decimals** | Yes | ERC-20 display decimals, commonly 18 | | **Image** | Yes | JPG or PNG image, up to 2 MB | | **Description** | No | Public token description | | **X, Telegram, Website** | No | Public social links attached to the profile | ### 2. Buy Mode | Setting | Description | | --------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | **Launch plan** | Sets the supply the dev wallet keeps, the bundle and the snipe on one bar, with the cost strip under it; see [Launch Plan](/getting-started/launch-new-token#launch-plan). Dev keeps plus bundle: 1% to 99.99% (**Max 99.99%**). | | **Initial Liquidity ETH** | ETH supplied by the dev wallet during pool setup. | | **Initial Liquidity Tokens** | Percentage of total supply supplied to the pool. The remainder stays with the dev wallet. | | **Pool Fee Tier** | Fee charged by the Uniswap V3 pool on every swap: 0.01%, 0.05%, 0.30% (default), or 1.00%. Initial liquidity always uses the canonical full range. | | **Bundle cost** | Launch plan cost strip: initial pool liquidity, launch buys with the pool fee, each wallet's gas reserve, and the deployer's deploy reserve. CEX funding buffers are not part of it; they are added in **Funds needed**. | | **Market cap** | Launch plan cost strip (**MCap after** with a snipe): estimated from pool composition after launch buys, using the ETH/USD reference price. | | **Dev keeps** | Launch plan row: supply the dev wallet keeps beside the liquidity instead of buying, 0% to 99.9999%. It is the complement of Initial Liquidity Tokens: editing it also updates Initial Liquidity Tokens. | | **Bundle ยท at launch** | Launch plan row: the share the bundle wallets buy from the pool, without the supply the dev wallet keeps. | | **Bundle Wallets** | Number of Base wallets used for launch buys, up to 200. With 0 bundle wallets the launch only deploys the token and adds liquidity: there are no launch buys. With Token Supply launch-fee payment the fee then comes from the supply the dev keeps outside the pool, so that retained share must be at least the fee share of supply; otherwise use a Launch Ticket. | | **Funds Per Bundle Wallet** | ETH reserved per bundle wallet for gas. Minimum 0.01 ETH. | | **Injection Wallets** | Optional extra wallets, up to 100, funded with ETH for activity after launch. They do not buy in the launch. | | **Funds Per Injection Wallet** | Shown when Injection Wallets is above 0. ETH sent to each injection wallet during funding. Defaults to 0. | | **CEX Funding** | Optional Husher funding path for distributing ETH to launch wallets. | | **CEX Funding Buffer Per Wallet** | Extra ETH added per wallet when CEX funding is enabled. Minimum 0.01 ETH. | | **Advanced Controls** | Pool Setup Slippage and bundle supply jitter. | | **Trading slippage** | Default 1%, at most 10%. Becomes the new profile's default slippage for strategies and instant trades, changeable later in profile settings. | Token cleanup and holder wallets are not available for Base launches. If you want bundle tokens redistributed to holder wallets after launch, see [Uniswap V3 Robinhood Launch](/launch-tokens/robinhood-uniswap-v3-launch). ### 3. Wallets Add, import, or generate wallets for each required Base role. | Role | Description | | --------------------- | ------------------------------------------------------------------------------------------------------------------------------------ | | **Dev Wallet** | Deploys the token, creates the pool, mints the liquidity position, opens trading, and receives retained supply and the position NFT. | | **Bundle Wallets** | Execute launch buys before public trading is opened. | | **Injection Wallets** | Optional wallets funded with ETH for activity after launch. They take no part in the launch. | You can use ready wallets, create new wallets, or buy aged wallets at this step. Ready-wallet paths include importing private keys, pulling wallets from [Wallet Farm](/wallet-farm/overview), or reusing wallets from another profile. Additional paths include creating new wallets or buying aged inventory from [Wallet Marketplace](/wallets/wallet-marketplace). Tax, holder and sniper wallets are not used by Base Uniswap V3 launches. ### 4. Funding Save the draft before funding. If CEX funding is enabled, deposit the estimated Base ETH into the funding wallet, check the balance, then use **Fund** to distribute ETH through Husher. If CEX funding is disabled, fund the dev and bundle wallets directly and use **Check Balances**. The funding table tracks ETH requirements for the dev and bundle wallets. It supports address copying, allocation randomization, per-wallet allocation edits, and balance checks. The dev allocation and final bundle allocation are auto-balanced from the target. ### 5. Strategies Optionally add starter strategies to the profile before launch. You can configure [Counter Trade](/strategies/counter-trade), [DCA](/strategies/dca), and [Limit Order](/strategies/limit-orders) strategies by hand, or apply a strategy preset: Sumo ships built-in **Hyped**, **Standard**, and **Staircase** presets, and your org can save its own presets for reuse across launches and imports. Strategies are saved with the draft and can be reviewed after the token is live. ### 6. Launch Preview The preview action sequence is: 1. **Deploy Token** - Deploys the ERC-20 launch token from the dev wallet with the selected fee tier baked in. 2. **Create Pool** - Creates the token/WETH Uniswap V3 pool, sets launch-wallet exemptions, and mints the full-range liquidity position while public trading remains closed. The preview shows the **Position NFT ID** once minted. 3. **Launch** - Starts the durable launch runner for bundle-wallet buys with live buy progress, opens public trading, activates the profile, and submits ownership renounce. > **Background Launch Runner** > > Base launches do not hold the browser request open for every wallet buy. After you click Launch, Sumo records progress on the project and continues the launch-wallet buy runner in the background. ## Snipe After Launch Optional **Snipe after launch** wallets buy right after the launch lands, with their own sizing, delay, max premium, pacing and gas priority. Set **Snipe Wallets** to 0 (the default) and the launch is unchanged. See [Snipe After Launch](/getting-started/launch-new-token#on-evm-launchpads). On Uniswap V3 the entry price is only known once the launch lands, so the form shows no supply estimate, and there is no holder cleanup toggle. ## After Launch When all launch buys confirm and public trading opens, the profile becomes active and opens in Live Trading. The dev wallet holds the full-range position NFT, so the pool's trading fees accrue to it: collect them with **Claim LP Fees** from the [Treasury dashboard](/treasury/treasury-dashboard). To commit the liquidity, [Lock Liquidity](/treasury/lock-liquidity) locks the position NFT through UNCX, permanently or until a date, and keeps its fees claimable; [Burn Liquidity](/treasury/burn#burn-liquidity) gives the liquidity and its fees up for good.
