Cookin is a fair-launch token launchpad on BNB Smart Chain. One transaction creates a token, opens its PancakeSwap V3 pool and puts the entire supply into it. There is no presale, no bonding curve, no graduation and no team allocation: the token trades on PancakeSwap, and on any wallet or aggregator that routes PancakeSwap V3, from its first block.

• Pick a name, symbol, logo, description and links. Name and symbol are fixed in the token contract; the logo, description and links can be edited later from the token page.
• Pick the pair: BNB, a stablecoin (USDT, USDC) or another major coin (CAKE, BTCB, ETH, SOL). Buyers pay in it, and your earnings are paid out in it.
• Optionally make a first buy. It executes inside the launch transaction at the opening price, before anyone else can trade, and does not pay the snipe tax (it still pays the normal 3%).
• Pay the $1 launch fee in BNB. The page sends a small buffer for BNB price movement; the launchpad refunds whatever is not needed.

The opening price is computed in the launch transaction from Chainlink's BNB/USD price, so a BNB launch opens at $5,000 whatever BNB trades at. Ticks come in steps of about 2%, so the actual opening value lands within about ±1% of $5,000. CAKE, BTCB, ETH and SOL launches are priced the same way with their own Chainlink feeds, and USDT and USDC count as $1. If a pair's Chainlink answer is more than an hour old, launches in that pair wait until it updates rather than opening at a wrong price. A stale BNB/USD answer also waives the launch fee, so stablecoin launches still go ahead.

The whole supply sits in one PancakeSwap V3 position that starts at the opening price and runs to the end of the price range. Buying moves the price up through it; it behaves like a constant-product market whose virtual reserve is the opening value. Selling can bring the price back down to, but never below, the opening price.

The position NFT belongs to the launchpad contract, which has no function that removes liquidity or transfers the NFT. Nobody, Cookin included, can pull it. If someone creates the pool ahead of a launch at a manipulated price, the launch moves the price back to the opening price before adding liquidity.

The buy tax is taken by the token as tokens leave the pool, so a buyer receives 97% of what the pool sends. Sells are never taxed, so anyone, the creator included, can always sell their whole balance. The token has no owner, no mint, no blacklist and no switch that can change the rates.

Buying on pancakeswap.finance or another app: set slippage to 4–5%. Many routers check the tokens that actually reach your wallet, which is 3% less than their quote, and reject the buy with the default 0.5% slippage. Sells carry no tax and work with normal slippage. The Cookin trade panel already accounts for the tax.

Snipe tax: in the launch block a buy pays 3% plus 90%. The surcharge falls in a straight line, one step per block, and is gone after 20 blocks (about nine seconds on BSC). Sells never pay it. All of it goes to the platform, so a creator sniping their own launch from another wallet gets none of it back.

The tax only applies to the official Cookin pool. A pool someone else creates for the same token elsewhere does not charge it.

Your 70% of the buy tax and of the pool fee builds up per token. Claim it from the token's page: the tax, which is held in the token, is sold into the pool in the same transaction and everything is paid to you in the pair asset (native BNB for BNB pairs). The claim takes a minimum price, so it cannot be sandwiched.

The fee recipient can hand the token's earnings to another address with setCreator on the token. Claim first: whatever is unclaimed at that moment goes to the new address.

Ownership of the launchpad sits with a 2-of-3 Safe, which can change the launch fee, opening value, snipe settings and listed pairs for future launches only, or pause new launches. It cannot touch existing tokens, pools, rates or locked liquidity.

Each token trades in one standard PancakeSwap V3 pool:

pool = PancakeV3Factory.getPool(token, pair, 10000)   // 1% tier
pair = WBNB (0xbb4CdB9CBd36B01bD1cBaEBF2De08d9173bc095c) or the pair token (USDT, USDC, CAKE, BTCB, ETH, SOL)
token.pool() returns the same address

• The contracts have not been independently audited yet.
• Creators may hold tokens from their first buy and can sell all of them at any time.
• Memecoins are volatile. A token can lose most of its value quickly.
• Always check the contract address; anyone can deploy a token with the same name elsewhere.
