A report from Castle Labs says on-chain real-world-asset perpetuals have expanded from a niche segment into a meaningful slice of crypto derivatives trading in less than a year. Monthly volume was below $1 billion in October 2025 and rose past $120 billion by August 2026, with a peak of $147 billion in July 2026. The segment also reached as much as 20% of total on-chain perpetual volume, while open interest remained concentrated in a handful of platforms led by TradeXYZ and Variational. The report focuses on Variational’s newly launched swap product, which it presents as an alternative structure for trading RWAs on-chain. Unlike perpetuals, which rely on demand-driven funding rates to keep contract prices near the spot index, swaps charge a once-daily holding cost tied to real financing terms from traditional finance liquidity partners. Initial listed markets include US100, US500, XAU, XAG and USOIL. Since launch earlier this month, those markets have generated $3.8 billion in volume and reached a peak open interest of $245 million. Castle Labs also compares execution costs across Variational, TradeXYZ, Lighter and Ostium. In the report’s samples, Variational was the cheapest venue in most larger trade sizes across US100, US500 and XAU, though XAG remained less deep than other swap markets. The study argues that predictable carry costs and access to external TradFi liquidity may make swaps more suitable than standard perpetuals for on-chain RWA exposure.

Castle Labs published a research report on Sept. 10 comparing execution costs between Variational’s swaps product and traditional perpetual contracts. The report said Variational is currently the lowest-cost venue for listed assets across most trade sizes, with a $1 million trade in the US100 market costing just $47. It also highlighted rapid growth in the RWA perpetuals segment, where trading volume rose from less than $1 billion in October 2025 to more than $120 billion in August 2026. According to the report, RWA perpetuals now account for roughly 12% to 13% of on-chain perpetual volume, after peaking at 20% in July. Open interest in the category stood at $4.9 billion at the time of publication, with TradeXYZ and Variational together making up nearly 90%.

This week’s crypto project developments spanned court rulings, platform enforcement, protocol revenue, governance decisions, and product rollouts. A federal court in New York dismissed securities claims tied to meme coins in the Pump fun class action and threw out all claims against Solana Labs, the Solana Foundation, and related executives, while allowing RICO fraud and unlicensed money transmission allegations against Pump fun’s operating company and three founders to move into discovery. Prediction market platform Kalshi issued its first lifetime trading ban, permanently barring former U.S. Representative George Santos, fining him more than $70,000, and accusing him of placing large trades and making misleading public statements tied to a contract on whether he would attend Donald Trump’s State of the Union address. Robinhood Chain posted $4.32 million in 24-hour app revenue on Friday, the highest among chains tracked, while its meme market accounted for more than $1.468 billion in trading volume. Arbitrum DAO reported $6.19 million in revenue for the first half of 2026, with Robinhood Chain contributing roughly $360,000 in July licensing fees. Ethena’s Fee Switch vote passed unanimously, activating programmatic ENA buybacks, while Polymarket launched perpetuals and World open-sourced its zero-knowledge identity verification toolkit ProveKit.

ARK Invest researcher Lorenzo Valente said contract-level analysis of Robinhood Chain suggests only a very small share of activity can be directly tied to Robinhood’s own users. He said swaps routed from Robinhood Wallet through 0x’s Settler contract account for less than 1% of transactions on the network. Even after including harder-to-identify long-tail activity, his estimate rises only to around 5%. BlockTempo said its own spot check of the chain pointed in the same direction. In a 152-second sample window on Sept. 5, Robinhood Chain processed 19,959 transactions, or roughly 131 per second, from 5,377 sending addresses to 1,650 contracts. The largest share went to a swap router contract, followed by Arbitrum’s ArbOS system contract and Relay. The ranking also included OKX DexRouter, several Uniswap contracts, and multiple token contracts tied to meme coin launch platform PONS. The report said Robinhood Chain, launched on July 1, is a permissionless Layer 2 built with Arbitrum technology. It uses chain ID 4663, has 100-millisecond block times, no native token, and charges gas in ETH. According to the report, tokenized real-world assets account for only 0.28% of on-chain DEX trading, while nearly 90% of chain revenue has come from meme coin trading.

Real-world asset markets kept expanding in the latest weekly review covering Aug. 28 to Sept. 4, 2026, with on-chain RWA market value rising to $38.76 billion and the number of asset holders reaching 3.298 million, according to RWA.xyz data cited by PANews. Stablecoins also continued to grow, with aggregate market capitalization climbing to $303.21 billion and monthly transfer volume surging 48.83% from a month earlier to $7.17 trillion. On the policy side, the U.S. Securities and Exchange Commission proposed an overhaul of transfer agent rules that have seen little change since the late 1970s, aiming to address blockchain-based recordkeeping and tokenized securities. In Singapore, the Monetary Authority of Singapore opened a consultation on changes to the Payment Services Act that would create a formal stablecoin framework, including limits on interest payments and a path for limited cross-border recognition. South Korea’s Financial Services Commission, meanwhile, set out a three-stage roadmap for tokenized assets centered on Korea Exchange-led pilots. Corporate activity remained broad. Intercontinental Exchange took a stake in tZERO, the London Stock Exchange said it is working on tokenized UK shares with Payward, and 21 global financial institutions said they plan to form a stablecoin joint venture. Funding announcements also pointed to continued investment in settlement rails, remittances, and new collateral models tied to AI infrastructure.

Circle and edgeX have extended their alliance as Arc's mainnet launch approaches. edgeX will be the flagship perpetual market on Arc when mainnet goes live on Sept. 16, offering 24/7 FX trading from day one. The launch line-up includes a USD/JPY perpetual contract and more than 150 markets for US stocks, commodities and crypto assets, all using Arc-native USDC as margin and settlement. Arc is Circle's Layer 1 network built for stablecoin finance, featuring the StableFX engine, an institutional RFQ system and round-the-clock on-chain PvP settlement, with USDC as native gas. Under the deal, edgeX will be the exclusive platform to list FX perpetuals on Arc Chain. The team behind edgeX counts Circle Ventures among its investors; the exchange has generated over $900 billion in cumulative trading volume and supports 24/7 perp trading in equities, commodities, FX and crypto. Circle and edgeX had also previously worked on EDGE Chain's native USDC issuance and CCTP integration.

Crypto derivatives are moving away from an era dominated by perpetual futures. The article argues that options, long overshadowed by perps because of their complexity and weaker capital efficiency, have reached a turning point as open interest in crypto options has, for the first time, exceeded that of crypto futures. It traces the old structure of the market, from Deribit’s early options venue and Binance’s add-on options product to the rise and collapse of DeFi options vaults such as Ribbon Finance, Friktion, and Knox. A major catalyst, according to the piece, was the Oct. 10, 2025 selloff, when forced liquidations on exchanges exposed structural weaknesses in perpetual contracts, especially path dependence and liquidation mechanisms that could wipe out delta-neutral basis trades during intraday stress. Since then, new market structure has emerged: Derive rebuilt around a central limit order book with RFQ and portfolio margin, Nasdaq-listed IBIT options quickly surpassed Deribit in open interest, and Coinbase acquired Deribit, bringing a leading offshore venue closer to the U.S. regulatory perimeter. The article also stresses that this growth is concentrated in regulated, centrally cleared venues rather than DeFi. On-chain options still account for less than 1% of total volume. Even so, tighter basis yields, lessons from the FTX collapse, and the composability of on-chain settlement are presented as forces pushing the options market into a new phase.

Crypto options, long overshadowed by perpetual futures, are moving back to the center of the derivatives market. In the article, author Vaidik Mandloi argues that the shift is no longer a niche story: options open interest has, for the first time, surpassed crypto futures, helped by a sharp rise in activity on Deribit and the rapid launch of IBIT options on Nasdaq. Since the start of 2024, combined bitcoin options open interest across Deribit and IBIT has grown about tenfold to $80 billion. The piece traces that change back to several forces. Perpetual futures, once dominant because they were simpler and more capital-efficient, showed structural weaknesses during the Oct. 10, 2025 sell-off, when liquidation engines and auto-deleveraging exposed supposedly market-neutral traders to directional risk. At the same time, options infrastructure improved. Derive rebuilt around a central limit order book, RFQ functionality and portfolio margin, while regulated central clearing gave institutional traders a framework closer to traditional finance. Mandloi also points to shrinking basis-trade yields, down from 25% annualized in 2021 to 4.46%, lessons from the FTX collapse, and the composability of onchain settlement. Even so, the current boom is concentrated on regulated, centrally cleared venues rather than DeFi. The article’s core claim is that crypto options are benefiting from a real repricing of risk rather than a temporary burst of speculation.
