What is a rug pull?
The usual mechanics
Most rug pulls trace back to one of a few root causes: the deployer holds an oversized share of supply bought cheaply at launch (often via sniping their own token), a mint authority or admin key lets them create more supply or pull liquidity later, or presale/team allocations concentrate enough supply that a coordinated dump craters the price.
What a launch mechanism can actually prevent
Fuze addresses the specific mechanics it controls: no wallet (including the creator's) can buy a disproportionate, cheaply-priced share at launch — a per-wallet cap is enforced on-chain — and the escrow that holds funds pre-launch has no private key, so there's no admin key that could divert buyer funds. If a launch doesn't fill its goal, 99% refunds automatically.
What it honestly doesn't prevent
Fuze doesn't control what happens after a token is live and trading — normal holders (Fuze-launched or not) can still sell into a falling price, and nothing about the launch mechanism changes a token's long-term fundamentals or community behavior. "No sniping and no admin key at launch" is a real, verifiable guarantee; "this token will hold its value" isn't something any launch mechanism can promise.
