Solana's "billions of daily transactions" are mostly not human commerce. The money pools in a few places — and the fastest-growing one is machines paying tiny amounts per API call.

What the transactions actually are
| Category | Evidence | Human vs bot |
|---|---|---|
| Validator votes | ~215M/day vs 154–182M user tx/day (Solana Compass, Sep 30–Oct 6 2026) | Protocol |
| DEX trading | ~37.6M tx / ~$16.1B in one tracked 24h; Solana >36% of global spot DEX volume in H1 2026, ~2x Ethereum | Mixed, heavy bot share |
| Arbitrage / MEV bots | Atomic arbitrage >50% of all Jito tips (74% peak); 90M+ successful arb tx/year at ~$1.58 avg profit | Almost entirely bots |
| Memecoins | Fell 40% → 16% of Solana DEX volume in H1 2026; pump.fun: 5.6M+ cumulative token deployments | Bot-heavy |
| DePIN | ~6–8% of daily transaction count | Machine traffic |
| Payments | Small fraction of chain activity; stablecoin swaps 19% of DEX volume | Mostly human |
Net: the majority of transactions are machine-generated; the majority of economic value comes from human-initiated trading flows that bots feed on.
How fees work
| Layer | Amount | Who gets it |
|---|---|---|
| Base fee | 5,000 lamports (0.000005 SOL) ≈ $0.00055 per signature, charged even on failure | 50% burned, 50% block producer |
| Priority fee | Averages ~0.000056 SOL (≈ $0.006); ~80% of user tx include one | 100% validator |
| Jito tips | Off-protocol bundle tips; >60% of priority-fee volume | Validators (minus Jito DAO's 5.7% TipRouter cut) |
Rent is a refundable deposit, not a fee — and a ~90% rent cut began activating August 2026.
Who collects the fees
| Product | The cut | Scale |
|---|---|---|
| pump.fun | ~0.02 SOL per token creation; 1% per bonding-curve trade; 0.25%/swap after graduation | Record week $10.03M; >$870M cumulative |
| Jupiter | 0% manual swaps; 0–0.5% Ultra mode | 30d volume $16.4B; >50% of Solana DEX volume |
| Raydium | 0.25% pool fee (12% buys RAY) | 30d fees $25.36M |
| Trading bots | ~1% per trade (Axiom, Photon, Trojan) | Axiom ~$42.4M in Q1 2026 |
| Fomo | ~$1 flat or 0.5% minimum per swap, gasless | $1.76M daily revenue on Sep 4 (beat pump.fun) |
| Jito | 5.7% of TipRouter tips to the DAO | ~$19.85M tips processed in Q1 2026 |
| RPC (Helius, QuickNode) | $49–$999/mo tiers | QuickNode launched x402 pay-per-use RPC in USDC |
| Birdeye (data API) | $39–$499/mo, or $0.001–$0.01 per call via x402, no API key | Solana-native token data |
The micropayment patterns that work
- x402 HTTP gate — 402 Payment Required, client signs a USDC transfer, facilitator settles. No API keys, no accounts. Coinbase CDP: $0.001/tx after 1k free.
- Offchain batch settlement — authorize per request, settle one USDC total on-chain. One routing service reports >$20K/month saved.
- Facilitator-less authorization — offline signed message verified on-chain; gas only (~6,800 lamports), zero markup.
- Program-level fee deduction — the program takes X% per instruction into a treasury (the pump.fun / Raydium pattern).
- Sponsored transactions — relayer pays gas, recoups inside the product fee ("gasless" UX).
The AI-agent angle, honestly framed
Solana leads x402 activity (~65% of agentic payments per the Solana Foundation; ~$14M weekly volume by Sep 2026; $600M annualized overall). But TRM Labs found only 0.6–7.5% of screened x402 value looks genuinely agentic — most is scripts and self-payments. The credible frame is programmatic micropayments, a fast-growing flow where the land grab is still early.
Where a new entrant should compete
First choice: an agent-native, per-call x402 service in a vertical niche — a single-purpose paid API (market data, wallet intelligence, compliance checks) at $0.005–$0.05 per call in USDC, shipped with a machine-readable skill file so agents discover and pay autonomously. ~90%+ margins after facilitator and chain fees; it monetizes net-new volume instead of stealing share.
Second choice: fee-undercut consumer trading in an underserved vertical (the Fomo playbook: gasless, ~0.5% fees). Proven, but needs distribution.
Avoid: general aggregators (Jupiter owns it), subscription RPC (price war over), facilitator-fee competition (race to zero), generic launchpads.
Caveats
- Post-Alpenglow, headline transaction counts fall ~55%+ with no change in user activity — historical "billions" figures need rebasing.
- No published per-category transaction-count shares for NFTs, payments, or liquid staking; no credible estimate of agents' share of transaction count.
- pump.fun's exact fee schedule has minor source conflicts; the 1% / 0.25% structure is the most consistently documented.
