Hook UVL is a token launchpad built on Ethereum mainnet and Uniswap V4. You can deploy ERC-20 tokens and attach on-chain hook mechanics — buyback & burn, dividends, fee splitting, staking rewards, gamified burns, and lottery-style swaps — without writing Solidity.

The platform has four main areas: Explore (discover launches), Launch (create a token),Portfolio (your launches), and per-token pages to view details and add liquidity.

• Install MetaMask (or another Ethereum wallet) and connect it via the button in the top navigation.
• Switch your wallet to Ethereum mainnet.
• Hold enough ETH for gas and for the launch fee (minimum 0.01 ETH sent with the launch transaction, plus any extra you configure as initial ETH).
• After the protocol is deployed, contract addresses must be configured by the team — until then, on-chain actions will not work.

Connect wallet

Click Connect Wallet in the navbar. Approve the connection in MetaMask. Your address is used to launch tokens, show your portfolio, and apply UVL fee discounts when you hold the platform token.

The Explore page lists tokens launched on Hook UVL. Each card shows the token name, symbol, hook type, supply, ETH raised, and when it was launched.

Click a card to open the token detail page. Use Explore to discover projects and see which hook mechanics they use.

Go to Launch and complete the three-step wizard. You must be connected and send at least 0.01 ETH with the transaction (configurable initial ETH can be higher).

Step 1 — Token config

• Name and symbol — your ERC-20 identity on-chain.
• Total supply — whole tokens (18 decimals applied on-chain).
• Tax % — optional transfer tax in basis points (0–100% UI maps to contract taxBps).
• Initial ETH — ETH sent with launch; minimum 0.01 ETH required by the UI.

Step 2 — Hook selection

Pick one of seven pool types (see Hook Types below). For Split Fee, add up to five recipient addresses and percentage shares that must total 100%.

Step 3 — Pool & launch

• Fee tier — 0.05%, 0.3%, or 1% Uniswap pool fee (common pairs use 0.3%).
• Initial price — starting ETH per token used to compute sqrtPriceX96 for the pool.
• Review — summary shows hook, tier discount, and estimated cost before you confirm in MetaMask.

After confirmation, you get a success screen with an Etherscan link. The factory deploys your token and hook and registers the launch on-chain.

Hooks are Uniswap V4 contracts that run custom logic on swaps (fees, burns, dividends, etc.). Choose one when launching:

UVL (V4LaunchToken) is the platform utility token. Holding UVL reduces your launch cost through tiered discounts shown in the navbar and on the final launch step:

When connected, your UVL balance and tier badge appear in the navigation bar if you qualify for Bronze or above.

Portfolio shows tokens you launched while connected with the same wallet used at launch time.

• Overview stats — tokens launched, ETH raised, active pools, and your wallet address.
• Launch cards — quick view of each project with link to Manage on the token page.
• Empty state — prompts you to connect or launch your first token.

Each launched token has a page at /token/[address]. There you can see token metadata, hook type, pool status, and use Add Liquidity to supply tokens and ETH to the pool (when the pool is initialized on-chain).

Open token pages from Explore, Portfolio, or by pasting the contract address into the URL after a launch.

Fees you may pay

• Network gas — paid to Ethereum validators for every transaction.
• Launch ETH — minimum 0.01 ETH (or more if you set a higher initial ETH amount); may be discounted with UVL tiers.
• Pool swap fees — go to LPs and hook logic per the fee tier you chose (0.05% / 0.3% / 1%).
• Transfer tax — if you set a tax % on the token, transfers may charge holders per your configuration.

Risks

• Smart contract risk — audits may not cover all edge cases; only launch amounts you can afford to lose.
• Impermanent loss — providing liquidity on Uniswap-style pools carries IL risk.
• Hook complexity — custom mechanics change how fees flow; read each hook description before launching.
• No financial advice — Hook UVL is a tool, not a recommendation to buy or sell any token.

Which network does Hook UVL use?

Ethereum mainnet. Your wallet must be on mainnet for launches and reads.

Do I need to code?

No. The launch wizard handles deployment and hook selection through the web UI.

Can I change the hook after launch?

No. Hook type is fixed at launch. For bespoke mechanics, request a custom hook before launching.

Why did my transaction fail?

Common causes: insufficient ETH, wrong network, rejected in wallet, or contract addresses not yet configured post-deploy. Check the error in MetaMask and on Etherscan.
