Uniswap ETH Launch
Launch an ERC-20 token on Ethereum Uniswap V2 with WETH liquidity, private bundle buys, tax controls, and starter strategies.
Sumo supports Ethereum launches through Uniswap V2 Ethereum. The flow creates an ERC-20 launch token, prepares a WETH pair, opens trading with initial liquidity, executes private bundle buys, and transitions the pre-launch draft into an active trading profile.
Prerequisites
Before launching, make sure you have:
- Token metadata ready: name, ticker, image, description, and social links
- Total supply and token decimals
- ETH for contract deployment, pool creation, initial liquidity, bundle buys, and gas buffers
- A launch plan: target supply control, pool-token percentage, bundle wallet count, and optional tax settings
- One dev wallet, one tax wallet, and the configured number of bundle wallets
WETH Quote Asset
Ethereum Uniswap V2 launches are WETH-quoted. In the form, operators enter ETH amounts; Sumo stores the profile quote asset as WETH after pool creation.
Launch Flow
The Uniswap ETH launch uses the same six-step launch wizard as other launch methods.
1. Info
Choose Uniswap V2 Ethereum in the Launchpad field, then enter the token and profile details.
| Field | Required | Description |
|---|---|---|
| Launchpad | Yes | Select Uniswap V2 Ethereum. 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
Configure liquidity, supply control, wallet counts, and optional token controls.
| Setting | Description |
|---|---|
| Supply Control Target | Total supply controlled by dev-retained supply plus bundle wallet buys. Range: 1% to 99.99%. |
| Initial Liquidity ETH | ETH supplied by the dev wallet when opening trading. |
| Initial Liquidity Tokens | Percentage of total supply supplied to the pool. The remainder stays with the dev wallet. |
| Estimated ETH Required | Estimated initial liquidity, bundle buys, gas buffers, and CEX funding buffers when enabled. |
| Estimated Market Cap | Estimated from Uniswap V2 reserves after bundle buys, using the ETH/USD reference price. |
| Dev Supply | Read-only value derived from total supply minus pool-token percentage. |
| Bundle Buy | Read-only value derived from supply-control target minus dev-retained supply. |
| Bundle Wallets | Number of EVM wallets buying in the private launch bundle. Ethereum Uniswap V2 supports up to 80. |
| Funds Per Bundle Wallet | ETH reserved per bundle wallet for gas. Minimum 0.01 ETH. |
| 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 | Slippage, bundle supply jitter, and bundle priority fee in gwei. |
Tax Controls
Tax Controls are optional. When enabled, the launch token is deployed with tax, wallet-limit, and tax-clog settings.
| Setting | Description |
|---|---|
| Initial Buy Tax / Initial Sell Tax | Taxes applied during the initial tax period after the launch bundle finalizes launch taxes. |
| Final Buy Tax / Final Sell Tax | Taxes applied after the tax switchover block window. |
| Tax Switchover Blocks | Number of blocks before final taxes replace initial taxes. |
| Max Supply Per Wallet Limit | Optional maximum token balance per non-excluded wallet, as a percentage of total supply. |
| Tax Clog | When enabled, tax tokens accumulate on the token contract and can be swapped to ETH for the tax wallet. |
| Max Tax Swap Amount | Maximum tax-token amount sold in one automatic tax-clog swap. |
| Min Blocks Between Tax Swaps | Cooldown between automatic contract tax-token swaps. |
3. Wallets
Add or generate wallets for each required EVM role.
| Role | Description |
|---|---|
| Dev Wallet | Deploys the token, creates the pool, supplies initial liquidity, opens trading, and receives retained supply. |
| Tax Wallet | Receives tax proceeds and submits later tax or limit updates. |
| Bundle Wallets | Execute private bundle buys after trading opens. |
Holder, sniper, and injection wallets are not used by Uniswap ETH launches.
4. Funding
Save the draft before funding. Saving creates the pre-launch project, role wallet groups, optional funding wallet, and generated token metadata.
If CEX funding is enabled, deposit the estimated ETH into the funding wallet, check the balance, then use Fund to distribute ETH through Husher. If CEX funding is disabled, fund the dev, tax, and bundle wallets directly and use Check Balances.
The funding table lets you copy addresses, randomize bundle allocations, edit earlier bundle wallet percentages, reorder wallets within the same role, and verify ETH balances. The dev allocation and final bundle allocation are auto-balanced from the target.
5. Strategies
Optionally add starter strategies to the profile before launch. These strategies are saved with the draft and can be reviewed after the token is live.
6. Launch Preview
Review metadata, supply composition, wallet counts, funding rows, and starter strategies.
For Ethereum Uniswap V2, the preview action sequence is:
- Deploy Contract - Deploys the generated ERC-20 launch token from the dev wallet.
- Create Pool - Creates the token/WETH Uniswap V2 pair.
- Simulate Bundle - Simulates the private launch bundle before submission.
- Launch Bundle - Opens trading with initial liquidity, executes bundle buys, updates the project to active when landed, and submits ownership renounce.
After Launch
Once the bundle lands, the profile becomes active and opens in Live Trading. You can monitor trades, review launch logs, activate starter strategies, and manage taxes or limits from the supported launch-token controls.
