pump.fun's API blocks browser origins; requests go through this relay (default r.jina.ai, ~20 req/min).
Any CORS-enabled mainnet RPC works — paste a Helius / QuickNode / Triton URL for higher limits.
Default: solana-rpc.publicnode.com (free, CORS-open). Swaps are routed by Jupiter (no router fee; covers pump.fun bonding curve, PumpSwap, Raydium, bonk) and signed locally in your browser. PumpPortal (0.5%) is only used if you enable the fallback.
