Overview

tavern is a non-custodial interface for creating and trading experimental coins. Your wallet signs every launch, buy, sell, and claim.

The short version

A launch creates the token, its WETH pool, and a permanently locked liquidity position in one transaction. There is no later pool migration.

Instant markets

Trading starts as soon as the launch transaction confirms.

Permanent liquidity

The V3 position NFT is held by the protocol locker permanently.

Your wallet, your approval

tavern does not take custody of your wallet or trading funds.

For creators

Launch a coin

Add a name, symbol, image, and description. Optional links help people identify your project. The metadata is published to IPFS, then the token and market are created atomically.

  1. 01

    Describe

    Choose a unique identity and review every field before publishing.

  2. 02

    Configure

    Optionally enter an ETH amount for your initial buy and route creator rewards across supported wallets.

  3. 03

    Approve

    Your wallet submits one transaction that creates the coin and its market.

Markets

Trade a market

Every coin trades against WETH in its own Uniswap V3 pool. Quotes use the live pool state; the final amount can move before your transaction confirms. The immutable trade helper scopes sell approvals to this protocol version and returns native ETH directly after a sale.

Price
The current pool price for one coin.
Market cap
Current price multiplied by the fixed total supply.
Price impact
How much your trade moves the pool price.
Slippage
The maximum quote movement your transaction will accept.
Unrestricted ERC-20

Trading is open from the launch block with no token-level buy, sell, transfer, or wallet limits. Every token reports the zero address as its permanent owner.

Milestone

Graduation

A market graduates when its 30-minute time-weighted paired WETH principal reaches 4.2 WETH. Graduation records a milestone; trading continues in the same pool with the same locked position.

Threshold4.2 WETH

Graduation is not a quality signal and does not guarantee future price, liquidity, or demand.

For creators

Creator rewards

Every swap generates V3 fees in WETH and the launched coin. For the current deployment, 70% is credited to the creator side and 30% to the protocol treasury.

70%Creator rewards
30%Protocol treasury

Anyone can collect pending pool fees into the locker. Only the credited beneficiary can claim their balance. Creator-side rewards can be split across up to 10 wallets when the active factory supports reward routing. Those recipient wallets and their shares become permanent when the position is locked.

Before you transact

Safety and risk

Experimental and unaudited

These contracts run on mainnet and have not been audited. Using them can result in permanent loss of funds.

  • Names, symbols, and images can be copied. Verify the token address.
  • Prices can move quickly, and thin liquidity increases price impact.
  • Transactions are submitted by your wallet and may be irreversible.
  • RPCs, wallets, indexers, interfaces, and smart contracts can fail.
  • Displayed prices and balances are estimates, not execution guarantees.

Common questions

FAQ

Does liquidity move after graduation?

No. The same Uniswap V3 pool and permanently locked position continue trading.

Can the creator withdraw the locked liquidity?

No. The position NFT is held permanently by the locker. Only earned trading fees can be collected and claimed.

Does tavern hold my funds?

No. Your wallet submits each transaction directly to the relevant contracts.

Is this available on mainnet?

Yes. The current website is configured for Robinhood Chain mainnet and transactions use real ETH.
