Launch a token on Arc. Everyone gets paid in USDC.

Two ways to launch

Every token has a fixed supply of 1,000,000,000, trades against USDC, and opens at about a $2.5K market cap. You choose where trading starts.

A direct pool is seeded single-sided: the pool starts holding only your token, so launching needs no USDC from anyone. The price can only move up from the opening price — nobody can ever buy in lower than the first buyer.

Creator tax

Creators can add a tax from 0% to 10% on top of the 1% base fee. It is charged by a Uniswap v4 hook, so it applies everywhere the token trades — not just on TSUKIPAD.

• Both directions. Buys and sells are taxed at the same rate.
• Before and after graduation. A curve launch keeps its tax once it moves into its pool.
• Always taken in USDC. The hook never takes a slice of the token, so tax never becomes sell pressure on it.
• Fixed forever. Once a token launches, nobody can change its rate — not the creator, not TSUKIPAD.

Where fees go

Everything a launch earns — the base fee and the creator tax — is added together and split 70% to the creator side, 30% to the platform. The split is the same at every tax rate.

Referrals

A launch made through someone's referral link pays that person 10% of the launch's fees. It comes out of the platform's share, so the creator loses nothing. Referrals apply to direct-pool launches.

Uniswap pays pool fees on sells in the token itself. TSUKIPAD sells those for USDC before splitting anything, so every payout above arrives as USDC.

Who earns the fees

The creator side (the 70%) goes wherever the launch chose. This is set once, at launch, and cannot be changed afterwards.

The platform's 30% is paid the same way in every mode — in USDC, to the treasury.

Developer buy

Creators get no free supply. If you want to hold your own token, you buy it — in the launch transaction, from your own pool, at the opening price, the same price the first outside buyer would pay.

• Enter an amount of USDC when you launch. Leave it empty to launch holding none.
• The USDC you spend stays in the pool, so there is money to sell into from the first block.
• What you bought is shown on the token page, so buyers can see how much the creator holds.

Snipe protection

Bots try to buy in the same block a token launches. A bonding-curve launch charges a buy tax for its first five seconds that makes that unprofitable, then disappears. It quarters every second:

The creator, the fee recipient, and up to 16 wallets the creator lists are exempt, so a team can still buy at launch. Snipe tax goes to the platform in full.

Graduation

A bonding curve graduates the moment $9,350 has been raised. Nothing needs to be triggered — the buy that completes the curve also opens the pool.

• 17.98% of supply (179,800,000 tokens) and the raised USDC go into a Uniswap v4 pool at the curve's final price — about a $52K market cap.
• That liquidity is locked forever.
• Any tokens left over from rounding are burned, so supply matches what exists.
• The creator tax and the fee mode carry straight over to the pool.

Collecting fees

Fees build up inside the pool as people trade. They are paid out when someone presses Collect fees — or Buy back & burn now — on the token page.

What can't happen

Locked liquidity and fixed rules protect against the launchpad being abused. They do not make any token a good investment. Tokens can lose all their value.

Contracts

Live on Arc Mainnet, chain 5042. Pools run on Uniswap's own v4 PoolManager. Every TSUKIPAD token address ends in 272.

For integrators

For wallets, trading bots, screeners and explorers. Everything below is free and public: show TSUKIPAD tokens with their real logo, links and fees without the creator paying for a listing.

Recognising a TSUKIPAD token

Every token is deployed by one factory, 0x6C939437b344aC25fD577d7BB625E151457a1a4f, which emits TokenDeployed(token, pad, creator, curve, name, symbol). Only count it when pad is the launchpad or the bonding curve listed under Contracts. Anyone can deploy a token that claims to be TSUKIPAD; only the pads' records are authoritative.

Token API

No key, no rate card, readable from any origin. Returns 404 for any address TSUKIPAD did not launch.

GET https://www.tsukipad.com/api/token/{address}
GET https://www.tsukipad.com/api/token/{address}/image

/image returns the logo as a normal PNG, JPEG or WebP, cacheable indefinitely — metadata is immutable once a token launches. Use it directly as an image URL.

Showing the right tax

The creator tax is not built into the token contract, so a transfer-tax check will report 0%. It is charged by the pool's Uniswap v4 hook, 0x5dED8fc500d9a81A91D7B86D9003045f788120cc, on every swap through any router:

• A buy pays fees.buyBps in total: the 1% pool fee plus the creator tax, taken from the USDC paid in.
• A sell pays fees.sellBps in total, with the tax taken from the USDC received.
• The rate is fixed at launch, capped at 10%, and the hook has no owner. It cannot block sells or change a fee.

Pools and events

Every pool pairs the token (currency0) with USDC at a 1% fee and tick spacing 200, on Uniswap's own PoolManager. Useful events:

ArcLaunchpad  Launched(token, poolId, creator, feeRecipient, name, symbol,
                       metadataURI, totalSupply, liquiditySupply,
                       tickLower, tickUpper, liquidity)
TsukiCurve    Launched(token, creator, name, symbol, metadataURI)
TsukiCurve    Trade(token, trader, isBuy, usdcAmount, tokenAmount, fee,
                    tokensSold, usdcRaised)
TsukiCurve    Graduated(token, poolId, usdcToPool, tokensToPool, liquidity)
PoolManager   Swap(id, sender, amount0, amount1, sqrtPriceX96, liquidity, tick, fee)
