Since May 21, 2026, a pump.fun creator can launch a coin paired to USDC as an alternative to SOL. It is an added option that leaves SOL-paired launches fully in place, and any coin already paired to SOL keeps working exactly as it did before. What changes is the asset the coin is priced against. A USDC coin is measured in dollars, so its starting market cap and the fee tiers tied to it are fixed dollar amounts, while a SOL coin's cap and tiers are measured in SOL, so their dollar value rises and falls with the price of SOL. The fee ceiling and floor stay the same either way, roughly 1.25% down to 0.3%, though the steps in between run on a separate, dollar-denominated table.
What a USDC-denominated launch is
As of May 21, 2026, a creator launching a coin can choose USDC as the paired token instead of SOL, and creating the coin stays free with either pairing (source: pump.fun fee page). The pairing sets what the coin trades and is priced against from its very first buy.
Everything after that works the way any pump.fun coin does. The coin trades on its bonding curve, and once it fills the curve it graduates to a canonical pool on PumpSwap, the same path a SOL coin takes through graduation. The pairing choice leaves that journey intact and simply changes the unit the coin is counted in.
Does USDC pairing replace SOL pairing?
This is the part that gets misreported: some coverage framed the update as pump.fun walking away from SOL, when in reality USDC pairing was added alongside it and existing SOL trading pairs stayed exactly as they were, so both options coexist for new launches (source: CryptoRank). A creator who wants SOL still launches with SOL, and USDC simply joins the same launch flow as a second choice, while any coin already paired to SOL carries on exactly as before.
What actually changes: dollars or SOL
The real difference is the denomination: because a USDC coin is priced in a dollar stablecoin, its starting market cap and the market-cap tiers that set its fee are fixed dollar figures, while a SOL coin's cap and tiers are set in SOL, so their dollar value floats with SOL. A coin paired to SOL effectively inherits SOL's price swings, so a drop in SOL reprices the coin even when its own demand holds steady (source: Crypto Briefing). Pairing to USDC replaces that link with a steady dollar frame.
The fees follow a similar shape for both pairings, since the bonding-curve fee runs at about 1.25% of a trade whether the coin is paired to USDC or SOL. After graduation, the canonical pool's fee still starts near 1.25% and slides down toward 0.3% as the coin grows, though a USDC coin runs on a separate, dollar-denominated schedule published on pump.fun's fee page. The fee-tiers guide lays out how those steps move as the coin grows, and the schedule applies to the canonical pool alone.
For a trader who wants exposure to pump.fun itself rather than to any single launch, PUMP, the platform's own protocol token, trades on BloFin as the PUMPUSDT Perpetual, a position on the token's price that sits apart from the coins minted on the platform.
The funding rate and the running cost of that position are set out on BloFin's fee page, the quickest way to see what a PUMPUSDT position is charging right now.
Why a creator or a trader might care
Both pairings are legitimate, because each measures the coin against a different thing. A USDC pairing gives a coin a steady dollar frame, so its market cap and the milestones people watch hold their level even as SOL moves. A SOL pairing keeps the coin tied to SOL, which is what most of the platform has always done. For a reader, the practical point is smaller than the headlines suggest: check what a coin is paired against before you read much into its price or its market cap, because a dollar number and a SOL number measure different things. The rest of how pump.fun charges you sits in the full fees guide.

Frequently asked questions
When did pump.fun add USDC-denominated launches?
On May 21, 2026. From that date, a creator launching a coin can choose USDC as the paired token instead of SOL, added as an option on the existing launch flow. Creating a coin stays free with either pairing, so the choice sits at the moment of launch and shapes what the coin is priced against from its very first buy.
Did pump.fun stop pairing new coins with SOL?
SOL pairing is very much still in place, and this is the common misread. USDC pairing was added alongside SOL pairing rather than in place of it, so SOL-paired launches remain available and existing SOL pairs carry on exactly as they were. A creator who prefers SOL still launches with SOL, and both options now coexist for new coins on the same launch flow.
What actually changes when a coin is paired to USDC instead of SOL?
The asset the coin is priced against. A USDC coin is measured in dollars, so its market cap and fee tiers are fixed dollar amounts, while a SOL coin is measured in SOL, so its dollar value moves with SOL's price. The pairing also puts the coin on a separate, dollar-denominated fee table, though the fee ceiling and floor stay the same either way.
Are the fees different for a USDC coin?
The fees differ only in the schedule between the extremes. The bonding-curve fee runs at about 1.25% of a trade for both pairings, and after graduation the canonical pool fee still starts near 1.25% and falls toward 0.3% either way. A USDC coin simply follows a separate schedule denominated in dollars, so the steps between the ceiling and the floor are set in dollar terms rather than SOL.
Does pairing to USDC remove SOL's price swings from a coin?
It removes the pairing's link to SOL's price. A USDC coin's dollar market cap holds its level even as SOL moves, while a SOL-paired coin's dollar value rides SOL up and down. The coin's own volatility stays, because that comes from its own demand on the bonding curve, so USDC pairing steadies the frame rather than the coin.
