Pump.fun

Pump.fun is a permissionless token launchpad and trading platform built on Solana that lets anyone deploy a new SPL token and begin trading it within seconds — at zero upfront cost, with no code to write and no liquidity to seed.

What It Is and the Problem It Solves

Before Pump.fun, launching a token required technical knowledge (writing or forking a contract), bootstrapping a liquidity pool, and often coordinating a presale or private round — creating obvious vectors for insider advantage and rug pulls. Pump.fun collapses that entire flow into a web form: name, ticker, image, optional description. The protocol handles everything else, and every participant sees the same starting price.

Core Mechanism: The Bonding Curve

Every token launched on Pump.fun trades against a constant-product automated market maker — the same mathematical model used by Uniswap and most major DEXes. Two virtual reserves, one denominated in SOL and one in the token's supply, are multiplied together to maintain a fixed invariant. Every buy increases the price; every sell decreases it. Price impact scales with trade size, which creates consistent, manipulation-resistant pricing from the moment of launch.

The total fixed supply for each token is one billion units. At launch, 800 million tokens are deposited into the bonding curve contract. There are no team allocations, no vesting schedules, and no presale tranches — all early participants buy from the same on-chain curve at market price.

Graduation to PumpSwap

The bonding curve is not permanent. Once cumulative buys push the token's market cap to the graduation threshold (approximately $69,000, reached when roughly 85 SOL has been accumulated in the curve), the curve closes and the full liquidity pool migrates atomically to PumpSwap, Pump.fun's own decentralized exchange that launched in March 2025. At that point the token begins trading in a conventional AMM pool. The protocol retains ownership of the migrated liquidity; Pump.fun neither seeds additional capital nor withdraws it after graduation.

Fewer than two percent of all tokens launched reach graduation, meaning the curve itself is where the vast majority of trading — and losses — occur.

Key Features

Permissionless creation. Anyone can launch a token for free (0 SOL creation fee). The only cost is the Solana network transaction fee.

Instant tradeability. Tokens are live on the bonding curve the moment they are created; no listing process, no approval required.

Fair launch design. Fixed supply, no pre-mined allocations, and transparent on-chain pricing mean all buyers see the same curve from the first trade.

PumpSwap. The platform's native DEX handles post-graduation liquidity. PumpSwap canonical pools use a tiered fee structure that decreases with market cap — starting at 1.25% for small caps and compressing to 0.30% for tokens with 98,240 SOL or more in market cap. The fee splits between protocol (0.05%), LP providers (0.20%), and creator at higher market cap tiers.

Mobile application. A native mobile app is available on iOS and Android, recently reinstated in the US and India App Stores, enabling trading, leaderboards, and creator discovery from mobile.

Callout Rewards. A social incentive layer built into the app awards cash prizes to traders who publicly call tokens that subsequently perform well. The platform distributed $10 million in callout rewards in a single month as of September 2026.

Arc integration. The Pumpfun app supports trading Arc-supported tokens with USDC at near-zero fees, expanding the universe of assets accessible through the platform.

By the Numbers

Pump.fun launched on January 19, 2024, and grew rapidly during the Solana memecoin cycle that followed. By January 2025, more than six million tokens had been created on the platform. Cumulative protocol fees have exceeded $700 million, with peak daily revenue above $10 million during the height of memecoin activity in late 2024 and early 2025. Annualized revenue as of mid-2026 runs at approximately $480 million. DEX volume through PumpSwap exceeded $2 billion in Q1 2026 alone.

PUMP Token

In July 2025, Pump.fun launched a native protocol token (PUMP) via a public ICO that sold out in twelve minutes, raising approximately $600 million publicly and $720 million in a concurrent private round. The token's primary utility is a buyback-and-burn mechanism: fifty percent of all protocol revenue is used to purchase PUMP on the open market and permanently burn it. As of September 2026, approximately $457 million has been deployed through this mechanism. Total supply is one trillion PUMP; approximately 166 billion tokens have been burned to date.

Team and Background

Pump.fun was founded by Noah Tweedale, Alon Cohen, and Dylan Kerler, three English entrepreneurs who registered the domain in September 2023 and launched the platform on Solana mainnet in January 2024. No public audit reports are cited in Pump.fun's documentation.

Solana Ecosystem Fit

Pump.fun is among the most significant applications on Solana by fee generation and daily transaction count. Its bonding curve contract (6EF8rrecthR5Dkzon8Nwu78hRvfCKubJ14M5uBEwF6P) and the PumpSwap AMM (pAMMBay6oceH9fJKBRHGP5D4bD4sWpmSwMn52FMfXEA) are among the most-called programs on the network. By making token creation and trading nearly free and instantaneous, Pump.fun has driven substantial retail activity and onchain volume to Solana, while also concentrating the network's memecoin speculation risk in a single, highly liquid venue.
