Pump.fun provides coin creation and trading on Solana. Its public creation form presents SOL, USDC, and Custom pairing choices. The trading feed also includes assets from other launch venues, so appearing in the app does not mean the coin was created through Pump.fun.
What is Pump.Fun
Email or social sign-in still involves a wallet. Pump’s sign-in modal says the same app login method brings the app wallet, while another method or an external wallet opens a different account. The displayed wallet choices conflict with a notice retiring web browser-wallet sign-in from Sep. 25, 2026.
That notice describes private-key import, while Terms Section 12.2(c) says Pump will never ask users to share private keys or recovery phrases. These conflicting instructions do not support a settled account-migration procedure.
How Pump.Fun Works
Ordinary coin purchases use curve trades without a conventional buyer allocation claim or vesting cliff. Pump’s synthetic-migration guide says curve buys and sells fail after completion until migration. The guide applies this pause to both v2 and v3 instructions, without promising a migration time.
Holder Rewards are conditional distributions with eligibility and costs, and the Terms say they may never be paid. Existing Cashback credits have their own claim mechanics.
Developments
Since its launch, Pump.Fun has expanded its support to include Ethereum Layer 2 networks Base and Blast, increasing its user base and functionality. The platform has become one of the most profitable apps in the crypto space, generating significant daily revenue.
Fees Associated with Pump.Fun
The Oct. 17, 2026 fee schedule adds a 0.45% web/mobile Platform Fee, or 0.40% with another user’s referral code applied, above applicable pool and network charges. It includes first buys and conditional-order execution. Terminal and third-party interfaces are excluded from this particular fee.
The ordinary SOL/USDC curve pool table lists 1.25%. Custom Creator fee guidance conflicts with the public configurable control and technical instructions, while Holder Rewards configurations have separate rules. No single total describes every route.
Summary
Mayhem is a separate launch configuration whose guide describes extra supply, possible agent trading, and particular exit risks. The current form’s toggle conflicts with an older guide saying the interface cannot select it.
The documented canonical migration sends liquidity to PumpSwap and burns the received liquidity-provider tokens. That does not make every pool or program rule immutable: technical documentation also describes global configuration and operation-disable authorities. A launch listing does not validate token quality or guarantee a liquid exit.
