HanokFair token launches on GIWA

Every launch starts on a bonding curve and graduates into a Uniswap V4 pool whose liquidity is locked forever. No presale, no team allocation, no rug.

Quick start

How it works

Open the app

📈

Fair bonding curve

The entire supply is minted to a constant-product curve. Price rises as people buy and falls as they sell, and you can always sell back before graduation.

🎓

Automatic graduation

The buy that sells the curve out seeds a full-range Uniswap V4 pool at the exact closing price, in the same transaction. Nothing is left for a creator to get wrong.

🔒

Liquidity locked forever

Pool liquidity is owned by a contract that has no withdraw function. Not the creator, not the protocol, nobody can pull it.

💸

Creators earn on every trade

A creator tax of 1–10% is chosen at launch and fixed forever, paid in ETH before and after graduation, on top of a flat 1% platform fee.

🛡️

Snipe protection

The first ten seconds of trading carry a tax that starts at 99% and halves every second, so racing a launch with a bot is pointless.

🧩

Built to integrate

Everything is on-chain and readable without any Hanok backend. Quote, index and trade with plain viem calls or any Uniswap V4 router.

What is Hanok?

Hanok is a token launch protocol on GIWA Chain, the OP-Stack Layer 2 built with Upbit. A creator deploys a token in one transaction, the public buys it from a bonding curve, and once the curve is bought out the launch graduates into a Uniswap V4 pool with permanently locked liquidity.

The name comes from the traditional Korean house whose roof is made of interlocking giwa tiles: many small pieces that, together, form something solid.

Testnet

Hanok currently runs on GIWA Sepolia (chain id 91342). Contracts are unaudited and every token is a test asset with no value. See the mainnet roadmap.
