When a pump.fun coin graduates, it gets one official trading pool on PumpSwap, and pump.fun calls that the "canonical pool". The coin itself is an open token on Solana, though, so other pools can hold the same coin too, and those extra pools are the non-canonical ones. The two are priced on different terms: the canonical pool uses pump.fun's tiered fee, which starts near 1.25% and falls as the coin grows and pays the coin's creator a slice, while a non-canonical pool charges a flat 0.3% and pays the creator nothing (source: pump.fun fee page). So the same coin can cost you two different fees, depending on which pool your trade lands in.
What a canonical pool is
When a coin fills its bonding curve and graduates, pump.fun opens a pool for it on PumpSwap, and that pool, the one graduation created, is the canonical pool. It is the coin's official home for trading once the bonding curve is behind it. PumpSwap is pump.fun's own exchange for graduated coins, so the canonical pool is the single market pump.fun treats as the coin's real one, and it is the pool pump.fun's own front end points you to.
What the canonical pool charges
The canonical pool prices trades on a sliding schedule that tracks the coin's market cap. At a small market cap the total fee starts around 1.25% of the trade, and it slides down step by step as the coin gets bigger, reaching about 0.3% at the largest sizes. The full fee-tier table breaks out every step in that schedule.
Two things hold across the whole schedule. The fee splits three ways, into a creator share, a pump.fun protocol share, and a slice that returns to the pool as liquidity. The creator also keeps some of it, even at the top sizes where the total drops to about 0.3%, so in the canonical pool the creator always earns a share of every trade.
What a non-canonical pool is, and what it charges
A pump.fun coin is an open token on Solana, an on-chain asset that any software can trade and that stays independent of PumpSwap (source: Solana docs). Because the coin is open, anyone can set up another pool that holds the same coin and quote their own price for it, and on PumpSwap any pool for the coin apart from the one graduation created is called non-canonical.
The fee is where the two pools split apart. The same pump.fun fee page sets non-canonical PumpSwap pools at a flat 0.3%, and in that split the creator's share is zero. So a non-canonical pool can come in cheaper than a small graduated coin's canonical pool, though the money that would have been the creator fee is simply left off the trade.
How you end up in one pool or the other
The pool your trade uses is often chosen for you, because many front ends and aggregators route your order to wherever the price looks best. Jupiter, a major Solana routing layer, breaks a single order into pieces that execute across several pools at once to improve the fill, so your trade in a graduated coin can run partly or wholly through a non-canonical pool while you simply take the best available quote. And beyond PumpSwap, the same coin often trades on other exchanges entirely.
So the fee you pay, and whether the creator earns anything, follow the route your order takes as much as the coin you picked.
Why the difference matters
Both pools are legitimate. They are simply priced on different terms and pay different people. For a trader, a non-canonical pool's flat 0.3% can undercut a small graduated coin's canonical fee, though a thin non-canonical pool can also give worse pricing once you account for how little sits in it. For the coin's creator, only the canonical pool pays them at all. The takeaway is simple: the same coin carries more than one price, so check which pool a trade uses before you size it.
To trade the PUMP token itself, BloFin lists it as a single market: the PUMP/USDT pair quotes one price and one fee, and what that position costs is laid out on the fee schedule.
Where PUMP trading fits
PumpSwap pools set the fee on a graduated coin, but they are one venue among several, and the same token also trades on centralized exchanges. There it lists as a standard pair with a single order book and a published fee, which many traders find easier to size and to exit than a scatter of on-chain pools.

Frequently asked questions
What is a canonical pool on PumpSwap?
It is the official pool pump.fun creates for a coin when the coin graduates from its bonding curve. It is the coin's main market on PumpSwap, the one pump.fun's own front end routes to, and it uses pump.fun's tiered fee schedule that pays the creator a share of every trade across the whole range of market caps.
What is a non-canonical pool?
It is any other PumpSwap pool that holds the same coin apart from the one graduation created. Because a pump.fun coin is an open token on Solana, anyone can set up a separate pool for it and quote their own price, and pump.fun's fee page charges these a flat 0.3% on every trade that runs through them.
Why do two pools for the same coin charge different fees?
Pump.fun prices them differently: the canonical pool uses a tiered schedule that starts near 1.25% and falls toward 0.3% as the coin grows, and it includes a creator share, while a non-canonical pool is a flat 0.3% where the creator's share is zero, which leaves the same coin carrying two fee structures at once.
Which pool does my trade use?
It depends on the front end you use: some route straight to the canonical pool, while aggregators like Jupiter spread your order across whichever pools give the best price, which can include non-canonical ones, so the pool is often chosen for you rather than picked by hand.
Does the creator earn from a non-canonical pool?
The creator earns nothing from a non-canonical pool, because the creator's share there is zero. Only the canonical pool pays the creator, and it does so across its whole fee schedule, even at the largest sizes where the total fee is at its lowest, which is the reward for the coin having graduated.
