One transaction, from your wallet. A launch is a call to the multiply router (0xB9De…5Acd), which builds the whole market on Doppler's Airlock: the token, the pool, the lock and the fee hook, with the shape every multiply coin shares. The router holds no funds and never touches a coin after its launch.
The token. A Doppler ERC-20 with fixed 1,000,000,000 supply, minted once. No mint function, no transfer tax, no pause, no blacklist. Its owner is the Airlock contract, which has no function to use that power. Burning is first-class: burn() reduces totalSupply.
The pool. The entire supply goes into a Uniswap v4 pool against USDG as a single one-sided position: an ask ladder starting at roughly $4,000 market cap. Every coin opens at the same valuation, whatever market or leverage it picked. Buys and sells are ordinary v4 swaps, routable by anything that speaks Uniswap. multiply.cash never custodies user balances.
The metadata. Name, ticker, the coin's seal and the engine settings (market, direction, leverage, take-profit) are pinned to IPFS and written into the token, signed by the launching wallet. Terminals and explorers read the logo from there; the keeper reads the engine settings.
The first buy. Optionally, a first buy in USDG is bundled into the launch through Doppler's Bundler: it is the pool's first swap by construction, so nobody can trade before the creator. The trading fee is waived on it except Doppler's slice.
