LaserSell Benchmarks

Open-source benchmarks comparing Solana transaction build latency across LaserSell API, PumpFun SDK, PumpPortal API, and Jupiter's Metis API.

Benchmark Results

From the Exit Intelligence Stream server

TX build time as experienced by Exit Intelligence Stream users. When the stream detects an exit condition, it calls the LaserSell API over the co-located network to build the sell transaction. This is the latency that matters for automated exits.

What's Compared

Method	Build approach
LaserSell API	Single API call. Server builds the transaction
PumpFun SDK	Local build. Multiple RPC calls for on-chain state, then local instruction assembly
PumpPortal API	Single API call to pumpportal.fun
Jupiter's Metis API	Two API calls. Quote then swap

Setup

cp .env.example .env

Fill in your .env:

Key	Required for	How to get
BENCH_MINT	All methods	Any Pump.fun token mint address
BENCH_WALLET	All methods	Your wallet pubkey (read-only, no signing)
LASERSELL_API_KEY	LaserSell API	Your LaserSell API key
RPC_URL	PumpFun SDK	Any Solana RPC provider (Helius, Triton, etc.)
JUPITER_API_KEY	Jupiter	Free at portal.jup.ag

PumpPortal needs no API key. Methods auto-skip if their required key is missing.
