Excerpt summary (featured): SolanaThe 2026 thesis is no longer just about ETF flows or an Alpenglow upgrade. The real demand driver is productivity-driven economic activity – US dollars and BUSD push bars, Deepin Networks (Helium, Render, io.net) and DEX volume from Jupiter and Raydium that now rival Ethereum L2s combined.
Most of Solana’s mid-May 2026 ETF coverage is focused on three stories: weekly ETF flows, an Alpenglow consensus upgrade scheduled for Q3, and bull/bear price targets for 2030. We’ve already mapped these drivers in our piece on Solana Alpenglow upgrade, ETF flows and price forecasts.
This article discusses the layer beneath the headlines – the three real economic flows that actually consume Solana block space and generate recurring fee revenue for the network. If you are trading SOL, these are the metrics that tell you whether the chain is there or not userAnd not just speculation.
1. Stablecoins on Solana: from payment path to settlement layer
Solana’s most underrated story of 2026 is Stable coin yield. As of Q2 2026, the total supply of stablecoins on Solana stands at over $13 billion, with USDC accounting for nearly 75% and PYUSD (PayPal’s stablecoin) growing faster than any other source on the chain.
Why does this matter for SOL holders? Three reasons:
- Fees are paid in SOL. Each USDC/PYUSD conversion incurs a base fee plus a priority tip denominated in SOL. Sustainable throughput of a stablecoin means a sustainable marginal supply of SOL from validators and routers.
- Integration with Visa, Shopify, and PayPal All have driven direct settlement traffic via Solana over the past 12 months, with PayPal expanding its trade pilot program to PYUSD-on-Solana for cross-border transfers in March 2026.
- Share TPS. Solana now processes approximately 35% of all on-chain stablecoin transfers globally by number of transactions – ahead of all of Ethereum L2 individually and approaching Tron’s share of small ticket transfers.
The point here is not that Solana “won” the payments. That is, the size of the payment has become Structural Contributor to the economics of the network, regardless of trader sentiment.

2. Deben: The quietest Solana Trench
Decentralized Physical Infrastructure Networks (DePIN) The vertical became the most defensive for Solana. The chain hosts the three largest DePIN projects by market cap:
- Helium – Fully migrated to Solana in 2023, now powering both Helium Mobile MVNO and IoT data networks. The number of subscribers exceeded 200,000 in early 2026.
- Introducing the network (RNDR) – A GPU compute network for AI inference and 3D rendering, with weekly task throughput increasing 4x year over year.
- io.net — Distributed GPU computation for AI training. The organization’s May 2026 integration with several large modeling labs pushed the weekly dedicated GPU hours past 8 million.
He adds Cell folders (Decentralized Street Mapping) and a long tail of smaller networks, DePIN now accounts for an estimated 6 to 8% of Solana’s daily transaction count. Most importantly, DePIN traffic is Non-discretionary – Sensors, miners and GPU nodes stabilize the chain regardless of the price movement of the cryptocurrency.
Solana wins this category for one reason: the cheap, fast, sub-cent-less end is the only environment where micropayments for sensor data or GPU seconds make economic sense. The Ethereum mainnet and most L2 languages are very expensive per transaction; Alternative L1 languages lack sharing of developers’ ideas and tools.
3. DEX Size: Jupiter, Raydium, Orca vs. L2 Stack
The third stop is Decentralized Exchange (DEX) Amount. Jupiter It remains the dominant pool with over 60% market share of Solana DEX flow, which is routed through it Radium, OrcaMeteora, Lifinity and a growing list of CLOB places.
During April and early May 2026:
- Solana DEX 7-day average trading volume: $7.8 billion
- total Ethereum L2 DEX size (a base + resolution + optimism Combined): $6.4 billion
- Solana share of total on-chain DEX trading volume (formerly Ethereum mainnet): ~38%
This gap closed steadily over 2024-2025 and reversed in early 2026 as memcoin and stablecoin pair activity remained focused on Solana while L2 volume was fragmented across pooled pools. Trader implication: Solana is the deepest non-CEX coin Liquidity A place for long-tailed tokens, which keeps the flow of demand – and associated fees/revenue prioritized – for recycling back into SOL.
Pair the macro view with the implementation: Phemex SOL/USDT perps offers transparent funding rates and tight spreads during the opening session in the US and Asia. For longer-horizon operations, Phemex Earn supports flexible SOL deposits so that idle inventory continues to operate.
How do these three flows combine?
Treat the three legs as one feedback loop:
- Stablecoins Consolidating the dollar-denominated settlement layer.
- Deepin Generates a number of non-optional, sticky transactions.
- Direct implementation size Converts the depth of liquidity into fees for auditors.
Each layer reinforces the other layers. The liquidity of the stablecoin makes DEX pricing tighter. The depth of the DEX attracts more stablecoin issuances. The DePIN order provides a base load of transactions during periods of low speculation. All of them drive revenue from priority fees paid at SOL.
This is the kind of cash flow story that ETF allocators eventually price in — but it happens on-chain nowbefore catching up with the broader narrative.
What this means for SOL traders in 2026
Some practical takeaways:
- See the weekly change in stablecoin supply on Solana. A high bid with stable price action is bullish. Low supply during high SOL is a vanishing divergence.
- Observe the size of Jupiter’s complex. Sustained daily volume of over $1 billion emphasizes organic activity rather than wash flow.
- The strength of the DePIN token is a leading indicator. When RNDR, HNT, and IO trend together, it indicates real economy demand for Solana block space independent of speculation.
- Combine with macro setting. Alpenglow upgrade and spot ETF inflows remain key catalysts; Utility metrics are the confirmation layer.

Instructions
Q1: Has Solana actually been used or is it mostly memecoin speculation? both of them. Memecoin trading is a real revenue contributor, but stablecoin payments (~$13 billion USD), DePIN settlement, and pool-oriented DEX flow combine to make non-Memecoin activity the majority of the daily transaction count as of Q2 2026.
Question 2: How do stablecoin conversions benefit the SOL price? Every USDC/PYUSD transfer incurs a base fee and pays a priority tip in SOL. Sustainable Productivity creates a continuous, non-speculative supply of validators, routers, and protocols that a SOL must have to work.
Q3: What is the best metric to track Solana fundamentals? Daily priority fee revenue (denominated in sol or USD) is the cleanest signal. It captures stablecoin flow, DEX volume, and DePIN settlement in a single number, and is published directly by multiple Solana dashboards.
