ROBINHOOD TO LAUNCH PERPS AND WEEKEND STOCK TRADING FOR US USERS

Robinhood announced plans to launch in-app perpetual futures trading for eligible US users in the coming months, covering bitcoin, ether, Solana, XRP, Dogecoin, ADA, LINK, and HYPE, with up to 10x leverage on bitcoin and ether and 3x on other assets, supported by Bitstamp at a 0.01% per-trade fee through year end. The company also plans 24/7 weekend trading for a curated list of US stocks and ETFs pending regulatory review, and launched Robinhood Agents, letting users build their own AI trading agents in the app, building on an agentic trading service from May that has drawn more than 150,000 users and now runs nearly 30 million actions a day.

EL SALVADOR LAUNCHES STABLECOIN APP ON BASE

Five years after mandating Bitcoin as legal tender, El Salvador is pivoting to stablecoins after BTC saw limited traction as a payment medium. The government is launching a digital dollar app built on Coinbase's Base network, targeting the remittance corridor where price stability matters more than the volatility Bitcoin carries. Remittances account for about 25% of El Salvador's GDP, making this a concrete test of whether stablecoin infrastructure can succeed where the BTC legal tender experiment stalled.

COMPUTE SOVEREIGNTY AND PROGRAMMABLE MARKETS

Simple Compute Market (SCM) introduces open-source infrastructure for programmable compute markets where sellers run sovereign storefronts, buyers negotiate prices peer-to-peer with seller nodes, and listings propagate through federated registries rather than a single controlled platform. The protocol unbundles roles that centralized marketplaces combine, enabling independent operators to run registries, storefronts, settlement services, and fulfillment systems while sharing interfaces that keep them interoperable. This design reduces compute dependency risk: high switching costs from opaque discovery and bespoke negotiation transform suppliers into structural lock-ins rather than interchangeable vendors. Arkhai is building an optional managed service layer on top of SCM while keeping the core protocol open source.

A GUIDE TO STRIPE'S STABLECOIN STACK

Stripe has released a modular stablecoin product stack covering card issuance, treasury management, global payouts, checkout acceptance, fiat on-ramps, cross-chain orchestration via Bridge, and programmable wallets via Privy, with businesses able to adopt individual components or the full suite. Live deployments include Shopify enabling stablecoin acceptance across 34 countries with automatic local-currency settlement for merchants, and Remote.com paying contractors in USDC across 60+ countries 2-3 days faster while cutting over 1% in FX costs. The stack also connects to open infrastructure through Tempo, a blockchain built for payments applications, and Open USD, an open standard for stablecoin issuance. These components collectively give enterprises a single vendor for building stablecoin-native financial products across both traditional and crypto rails.

BLOCKCHAINS CREATE NET NEW MARKETS

For most of financial history, new markets were constrained by listing committees, legal frameworks, and geographic fragmentation, which throttled how fast new risk units and instruments could emerge. Blockchains remove both constraints by making issuance permissionless and distribution global, and every major crypto category, from perps and spot DEXs to prediction markets and tokenized physicals, reflects value accruing to whoever controls issuance and exchange of net new markets. Hyperliquid exemplifies the dynamic: HIP-3 and HIP-4 let users launch derivatives on a shared global venue, onchain RWA perps reached a $1.4T annualized run-rate in July, and WTI found price discovery on trade.xyz during an oil shock while CME was closed. The addressable universe extends beyond existing assets to any risk that can be oracled and made two-sided, pointing toward expansion into compute futures, macro indicator perps, and markets that traditional finance never listed.

THE PRIVACY CABAL HAS GONE ALL IN ON QUANTUM

Quantus, launched September 9, is a proof-of-work chain that mirrors Bitcoin's 21-million-coin monetary policy while replacing ECDSA with ML-DSA lattice-based signatures (NIST FIPS 204) and adding Zcash-style shielded addresses. The project raised $2.42 million across two rounds at a $100 million valuation, with Balaji leading the second round and Naval Ravikant's fund and AngelList co-founder Babak Nivi also participating. The quantum risk thesis has grown specific: Google reduced the Bitcoin elliptic curve attack to under 1,200 logical qubits in March, NIST will deprecate elliptic curve signatures after 2030, and 6.04 million BTC (~30% of supply) sit in addresses with already-exposed public keys that BIP-360 cannot protect without a coin migration. The circulating market cap is about $2 million against a $1.26 billion FDV, with 73% of coins not yet mined and 26% locked by contract until September 2027.

WHAT HAPPENS WHEN STOCKS BECOME PROGRAMMABLE?

Tokenized stocks like xStocks operate as fully collateralized tracker certificates rather than direct equity, giving holders price exposure without shareholder voting rights. The price peg relies on authorized institutions arbitraging between underlying shares and tokens. On weekends when stock markets are closed, hedging constraints cause spreads to widen. Onchain equities unlock DeFi composability: existing lending protocols like Kamino accept selected xStocks as USDC borrowing collateral, and stock tokens can settle atomically against stablecoins in a single transaction. Developers can reuse existing wallet infrastructure and smart contracts to build thematic indices, structured products, and cross-protocol collateral tools on top of these assets.
