The pool
After graduation a coin trades on a Uniswap V4 pool paired with ETH. Swaps go through the same trade panel in the app, and the pool is a standard V4 market that any V4-compatible router can reach.
The pool exists before it opens
A coin's pool is created in the same transaction as the coin, before a single trade happens, and stays dormant until graduation. Its rules, its fee behaviour and its extensions are set at that point.
Nothing has to be assembled at graduation, which removes the moment where most launches go wrong: there is no scramble to create a market, and no window in which someone holds the raise.
The swap fee
There is no platform rate here. What a swap costs is chosen by the creator at launch, within limits the pool contract enforces, and it cannot change over the coin's life.
- The recommended setup is the dynamic fee, which follows the coin's own volatility. Its suggested values step from 0.30% in calm markets to 1.20% when the price is moving hard.
- A creator can retune those steps, or drop them for a flat fee, which the form offers at 1% by default and accepts at any value.
- No fee can exceed 10%, except inside a declared sniper tax window, and the protocol always keeps an incompressible 0.03% of every fee.
The coin's page shows what it charges and which modules produce that number. Two coins on Frontier can cost very different amounts to trade, which is why it is worth reading before trading. See Trading fees.
Locked liquidity
The liquidity seeded at graduation is held by a protocol contract whose code contains no way to withdraw it. Not the creator, not the protocol team, not anyone. Only the fees it earns are ever collected.
Anyone can trigger that collection, so a creator is not waiting on the team to be paid. What is collected splits 75% to the creator and their community, 25% to the protocol.
Liquidity from anyone else
A V4 pool is permissionless: anyone can add liquidity to a graduated coin's pool. Liquidity added that way earns its own share of the LP part of each fee and is not subject to any Frontier rule. It can also be withdrawn by whoever provided it, unlike the position locked at graduation.
