PumpPortal

PumpPortal is an unofficial, third-party developer API built on Solana that provides programmatic access to the Pump.fun token ecosystem and associated decentralized exchanges. Created by an independent developer known as thetateman on GitHub, it launched in 2024 to fill a gap left by Pump.fun having no official API. Pump.fun created a high-velocity token launch environment on Solana with thousands of new tokens daily, but developers building bots, trackers, or arbitrage tools had no programmatic interface. PumpPortal abstracts the complexity of Solana transaction construction, giving developers a simple HTTP or WebSocket interface with no libraries to install. The service offers two transaction APIs with different security models. The Lightning Transaction API (endpoint: pumpportal.fun/api/trade) handles signing server-side: developers generate a Solana wallet and API key through the portal, the private key is embedded in the key using AES-256 encryption and never stored on PumpPortal servers, and the backend signs and broadcasts transactions via dedicated Solana nodes, SWQoS providers, and Jito bundle relays for low-latency inclusion. The Local Transaction API (endpoint: pumpportal.fun/api/trade-local) is non-custodial: it returns an unsigned serialized transaction that developers sign with their own keypair and broadcast via their own RPC. PumpPortal never sees private keys in this flow. Both APIs support six exchange targets via a pool parameter: pump (Pump.fun bonding curve), pump-amm (PumpSwap, the Pump.fun AMM launched March 2025), raydium, raydium-cpmm, launchlab, and bonk, with auto for automatic routing. Tokens that fill the Pump.fun bonding curve graduate to PumpSwap by default since March 2025. A WebSocket data feed at wss://pumpportal.fun/api/data provides four event streams: subscribeNewToken (token creation events, free), subscribeMigration (bonding curve graduations, free), subscribeTokenTrade (all trades on specific tokens, metered at 0.01 SOL per 10,000 events), and subscribeAccountTrade (trades by specific wallets, same rate). A funded API key with at least 0.02 SOL is required for metered streams. The data service covers both Pump.fun and PumpSwap activity and is mainnet-only with no historical data. Trading APIs carry a 0.5 percent fee per transaction. The project has no disclosed team, company, or security audit, and no formal open-source license; community support is through a Telegram channel. PumpPortal is explicitly unofficial and is not affiliated with Pump.fun, Raydium, or any other DEX it routes to. The GitHub repository has 151 stars and 12 forks. PumpPortal is primarily used for latency-sensitive bot strategies: token snipers buying in the same block as a new launch, arbitrage systems, wallet monitors, and automated portfolio managers. It takes advantage of Solana-specific infrastructure including Jito MEV bundles for atomic execution and stake-weighted quality of service for transaction priority.
