Key points
The main growth drivers for Solana in 2026 will be stablecoin payments, DePIN activity and DEX trading volume. These three factors create real demand for the chain, which is different from mere speculation.
Main takeaways: SolanaThe talking points for 2026 aren’t limited to ETF inflows or Alpenglow upgrades. The actual demand on the network is driven by the economic activity centered on the TPS, i.e. US dollars and BUSD This comes from the payment infrastructure, the DePIN network (Helium, Render, io.net), and DEX trading volume based on Jupiter and Raydium, which currently fully rivals Ethereum L2.
Our mid-May 2026 coverage will focus primarily on three things: weekly ETF cash flows, Alpenglow’s scheduled Q3 upgrade, and price forecasts through 2030. About that already Solana Alpenglow upgrade, ETF flows and price forecastsWe’ve got you covered in.
In this article, we focus on the real economic flows beneath the surface issues: the three main factors that actually consume Solana’s block space and generate recurring fee revenue. If you are an investor trading SOL, this is an indicator that allows you to check if the series is actually “used” rather than a speculative transaction.
1. Solana stablecoin: from payment infrastructure to settlement layer
Solana’s most underrated issue in 2026 is: Stable coin Transaction productivity. As of Q2 2026, the total supply of stablecoins within Solana exceeds $13 billion, with USDC accounting for nearly 75%, with PYUSD (PayPal’s stablecoin) growing even faster.
Three things that are important for SOL holders:
- Fees are paid by SOLIt works. All USDC/PYUSD conversions are SOL with base fees and priority burning. The constant flow of stablecoin transactions creates constant demand for SOL from validators and routers.
- Integration with major companies like Visa, Shopify, and PayPalReal-time payment settlement has been taking place on Solana for the past 12 months, and PayPal expanded its Solana-based PYUSD international transfer program in March 2026.
- Share TPS On the other hand, Solana currently processes approximately 35% of global stablecoin transactions on-chain. This is ahead of the Ethereum L2 in question and close to Tron in the area of micro transfers.
This does not mean that Solana “controlled” the payments market, but that the volume of payment transactions has become a structural part of the network’s economy.

2. DePIN: Solana’s quiet competitive advantage
**The Decentralized Physical Infrastructure Network (DePIN)** has grown to become the most defended area of Solana. Solana is home to the three largest DePIN projects by market cap:
- Helium – Support for Helium Mobile MVNO and IoT networks after full migration to Solana in 2023. Subscriber count exceeds 200,000 in early 2026.
- Rendering Network (RNDR) — GPU computing network for AI inference and 3D rendering, resulting in a 4x increase in weekly workload year over year.
- io.net — A distributed GPU computing platform for AI training. In May 2026, enterprise integrations with several large modeling labs resulted in more than 8 million hours of cumulative weekly GPU usage.
here Cell folders(Decentralized Mapping) and many smaller networks, DePIN currently accounts for approximately 6-8% of Solana’s daily transactions. DePIN traffic is inelastic because sensors, miners, and GPU nodes essentially settle on-chain, regardless of the market price.
Solana is ahead of the curve for one reason: only low-cost, ultra-fast payment environments make sensor data and Layer 2 GPU micropayments economically viable. The Ethereum mainnet and many L2 languages have high costs per transaction, and alternative L1 languages lack developers and ecosystems.
3. DEX Trading Volume: L2 stack competition with Jupiter, Raydium, and Orca
The third is DEX (Decentralized Exchange) Trading volume. JupiterIt is the main aggregation platform, collecting more than 60% of Solana DEX transactions. Radium, OrcaLiquidity is distributed across several exchanges such as Meteora and Lifinity.
From April – early May 2026:
- Solana DEX 7-day average trading volume: $7.8 billion
- Combined trading volume of Ethereum L2 DEX (Base, Arbitrum, Optimism): $6.4 billion
- Solana share of total on-chain DEX transactions excluding Ethereum mainnet: ~38%
This gap gradually narrowed in 2024-2025 and reversed in early 2026. This is because Memecoin and stablecoin trading is concentrated on Solana, while L2 trading volume is spread across multiple clusters. As a result, Solana serves as the primary platform for long-term token liquidity outside of CEX, with the resulting fees and prioritized revenue recycled back to SOL.

Interaction of three flows
If you look at these three as one feedback loop:
- Stable coinA dollar-based settlement layer is created.
- DeepinThis creates an inelastic and continuous transaction.
- DEX trading volumeConverts deep liquidity into auditor fees.
Each layer reinforces the other. Stablecoin liquidity tightens DEX prices, and DEX depth causes more stablecoins to be issued. DePIN ordering provides a stable floor for transactions even in times of low speculative trading. All of this forms the basis for the priority fee revenue paid at SOL.
This phenomenon may be priced in by ETF managers over time, but these changes actually happen on the chain.
Implications for SOL traders in 2026
Practical notes:
- Monitor weekly changes in stablecoin supply within Solana: If supply increases and prices remain stable, this is a positive indicator. Conversely, if supply falls when SOL rises, caution should be exercised.
- Checking Jupiter’s total trading volume: A consistent trading volume of over $1 billion per day indicates organic activity.
- DePIN code strength is a key indicator: If RNDR, HNT and IO are strong at the same time, it means there is actual demand for Solana block space regardless of speculation.
- Combined with macro events: Alpenglow Upgrades ETF flows remain key catalysts, but utility indicators act as confirmation.

Instructions
Q1: Is Solana actually being used or is it mostly Memecoin speculation?
Both exist. Although Meme Coin trading is a significant source of revenue, the total volume of stablecoin payments (total supply ~$13 billion), DePIN settlements, and DEX totals will make up the majority of daily transactions in physical activity as of Q2 2026.
Question 2: How do stablecoin conversions affect the price of SOL?
For each USDC/PYUSD transfer, the base fee and priority tip are burned and paid in SOL. Static transaction processing means that validators, routers, and protocols must continuously maintain SOL for the network to function.
Q3: What is the single best indicator for Solana Fundamentals?
Daily priority fee revenue (in Sol or USD) is the clearest indication. Stablecoin flows, DEX trading volume, and DePIN settlements are reflected in these numbers, which can be viewed in real-time across multiple Solana dashboards.
