At token creation, the manager creates or adopts only an uninitialized canonical token/WETH pool and initializes it at the curve's terminal price. An already initialized or unsafe candidate is rejected. At graduation, the manager verifies that exact price again before settlement.

The production frontend validates pool and periphery bytecode and relationships before quoting or swapping. Buy swaps wrap ETH to router-held WETH in a multicall; sell swaps use an ERC-20 approval and unwrap WETH output to ETH.
