How Yongmaru works

Yongmaru launches meme tokens on GIWA. Every token starts on its own bonding curve inside one launchpad contract, and climbs it trade by trade until it reaches the ridge.

Three things work together:

One contract. The launchpad creates each token, holds its curve and is the market for it. There is no separate pool to find and no router in between.
A curve per token. Price comes from a constant-product curve against virtual reserves, so a token has a price from its first second without anyone adding capital.
A ridge. Once enough ETH has gone into a curve, the token is marked as having reached the ridge and becomes ready to move to an open market.

You keep your own keys and sign every transaction yourself. Nothing is custodied by the site.

§ 02

Launching a token

Choose a name (up to 48 characters), a ticker (up to 12) and an optional image and description, then confirm one transaction. The contract mints a fixed supply of 1,000,000,000 tokens: 800,000,000 go onto the curve to be sold, and 200,000,000 are held back for the move to an open market.

The creator gets no allocation. You can add ETH to the launch transaction to make the first buy, which lands in the same transaction, before anyone else can trade, and pays the same price and fee as any other buy.

§ 03

Trading

Buys and sells run against the curve with the standard constant-product formulas:

tokensOut = tokenReserve × ethIn    / (ethReserve   + ethIn)
ethOut    = ethReserve   × tokensIn / (tokenReserve + tokensIn)

The ETH side includes a fixed amount of virtual ETH that sets the opening price. It is never paid out and cannot be withdrawn. Every trade carries a minimum you will accept and a deadline, so a trade that would fill worse than you agreed to reverts instead.

§ 04

Fees

Each trade pays a fee, currently 1%. The cap of 2% is written into the contract, so no one can raise it past that. 30% of every fee goes to the token's creator, who claims it from the contract whenever they like. The rest goes to the platform.

§ 05

The ridge

When the real ETH in a curve reaches the graduation target, the token reaches the ridge. On most launchpads that freezes the curve. GIWA has no DEX yet, and freezing would leave every holder with nowhere to sell.

So here the ridge is a mark, not a stop. The curve keeps quoting and holders can always sell back. Once a DEX exists on GIWA, the liquidity and the 200,000,000 reserved tokens can move to it, one time per token.

§ 06

What the owner can do

The owner can set who receives the platform fee, change the fee within the 2% cap, and set the migrator once, when there is a DEX to migrate into.

The owner cannot touch the ETH in any curve, mint tokens, pause trading or block an address. There is no path in the contract from the owner to a holder's money.

§ 07

The testnet

Everything on this site runs on GIWA Sepolia, a testnet. The board, token pages, portfolio and leaderboard read the launchpad contract directly; test ETH comes free from a faucet and has no value, and neither do the tokens launched here.

While GIWA mainnet is on its way, the testnet draw is open: active wallets enter a random draw for the Yongmaru token airdrop at mainnet.
