Solana's May 2026 Ecosystem Roundup: RWA Hits $2.8B ATH, Stablecoins Reach $16.4B, ETFs Post Best Month Since Launch

The Solana Foundation's May 2026 ecosystem roundup catalogues a month in which several network metrics simultaneously reached new highs: tokenized real-world assets topped $2.8 billion for the first time, stablecoin supply hit $16.4 billion, and spot Solana ETFs posted their strongest month of net inflows since launch.

Multiple records across RWA, DeFi, payments, and infrastructure landed within the same calendar month rather than in sequence.

RWA Hits $2.8B All-Time High as Holder Base Expands

Solana's on-chain RWA market crossed $2.8 billion during May, a new all-time high per the Foundation, with 230,000-plus onchain RWA holders, itself a record. For the first time, tokenized stock holders alone exceeded 200,000.

The network's dominance in tokenized equities remained striking: Solana accounted for 97% of cumulative onchain tokenized equities spot trading volume across all chains, per the Foundation roundup. The Backpack Securities launch contributed to that trajectory, as did the earlier Orca permissioned pools infrastructure for compliant RWA trading.

Beyond equities, RWA issuance expanded into less conventional categories. OnRe Finance, a reinsurance protocol, grew to $178 million AUM and closed a $5 million Series A. ONyc, a New York commercial real estate product, reached $100 million in active market cap with 6,200 holders. RockawayX opened a $40 million USDC USDC RWA vault supply. Bullish, the NYSE-listed exchange, tokenized 151 million of its own shares on Solana.

Asset types now span reinsurance contracts, commercial real estate, listed equities, and commodities, well beyond the Treasury-bill tokenization that dominated early RWA adoption cycles. Per CoinEdition citing RWA.xyz, Solana holds 28.2% of all on-chain RWA asset holders globally as of early June, second only to Plume at 29.8%.

This follows the Q1 trajectory documented in Galaxy Digital's recent research, which placed Solana RWAs at $2.5 billion at quarter-end with 58% quarterly growth.

Stablecoin Supply Reaches $16.4B with New Issuers

Solana's stablecoin supply reached $16.4 billion in May, per the Foundation, with the month notable for the quality of new issuers rather than aggregate growth alone. Western Union launched USDPT, described by the Foundation as the first stablecoin issued by a U.S. national bank to become available on Solana. SoFi launched SoFiUSD (SoFiD), extending its stablecoin infrastructure to 15 million existing members. New fiat-referenced tokens for the Korean won (KRWQ) and Kazakhstani tenge (KTZE) also went live.

Mayan, the cross-chain bridge protocol, moved $2.5 billion in stablecoins during the month across 600,000-plus transactions and crossed one million external wallets bridged.

DeFi: Record Perps Volume, $1B Ethena Markets

Perpetuals volume hit a monthly record of $64.6 billion in May, per the Foundation. Kamino Finance KMNO$0.015-5.7% Kamino Finance's Ethena market reached $400 million in size within 24 hours of launch, described by the protocol as "the fastest market expansion in Kamino's history," and combined Ethena markets across Jupiter JUP$0.200-0.5% Jupiter Lend and Kamino crossed $1 billion. Solstice, a fixed-rate lending protocol, grew to $500 million in TVL.

On the liquidity infrastructure side, Raydium Raydium's CLMM and Meteora's limit-order integration with Orca Orca deepened DEX composability. Solana apps generated approximately $91 million in total revenue in May, leading all blockchains per DeFiLlama data.

Solana Spot ETFs Post $115.3M in May, Best Month Since Launch

US spot Solana ETFs drew $115.3 million in net inflows in May, the best month since October 2025, bringing cumulative AUM to $1.13 billion, per the Foundation. Zero outflow days were recorded across the month. That ETF performance arrived while Bitcoin ETFs shed $2.3 billion over the same period, per our earlier reporting.

Western Union Stablecoin, AirAsia MOVE, and Consumer Payment Integrations

Western Union's USDPT was among several mainstream financial integrations during May. Cash App, SoFi, and Flipcash expanded stablecoin access, and AirAsia MOVE, the airline's digital wallet, integrated Solana payments. Mastercard named Solana as one of eight blockchains for always-on card settlement via USDC and other stablecoins in a related announcement in early June.

The Collector Crypt collectibles platform crossed $1 billion in platform volume with a 40 million-user ComicBook partnership. Phygitals, which bridges physical goods to onchain tokens, reached $250 million in platform volume.

P-Token Cuts Compute Costs 96%; Arcium, OTL, and Validator Progress

On the protocol layer, the P-Token upgrade reduced token instruction compute costs by approximately 96% and freed 12-13% of additional block space, per the Foundation. Arcium's Mainnet Alpha processed 200,000-plus encrypted computations, expanding confidential computing availability for institutional use cases.

Firedancer, Jito JTO$0.634-1.1% Jito, and Anza continued parallel work on validator client diversification and performance. The Open Transaction Layer launched with 30-plus partners including Robinhood and MetaMask, as reported in early June, providing a shared coordination standard for on-chain finance infrastructure.

Web3.js 3.0 (Kit), Termina's historical simulation tooling, and Packet MCP for agentic transaction routing completed a developer tooling month the Foundation characterized as infrastructure-heavy.

Five Simultaneous Records Signal Broad-Based Network Growth

RWA value, stablecoin supply, tokenized equity holder counts, perps volume, and ETF inflows each set records independently in May rather than any single metric pulling the headline. The Galaxy Q1 2026 research that framed the RWA growth trend as a structural story now has a Q2 data point behind it.
