TLDR Crypto 2026-04-09

An NYT investigation claims British cryptographer and Blockstream CEO Adam Back as the most likely identity behind Satoshi Nakamoto, citing stylometric analysis by linguist Florian Cafiero that found Back the closest match to the Bitcoin white paper among 12 suspects. Shared writing tics (e.g., double spaces between sentences, British spellings, hyphenating "proof-of-work," and identical technical phrasing like "partial pre-image" and "burning the money") form the core of the circumstantial case, alongside Back going largely silent on the Cryptography mailing list during the exact period Satoshi was active and re-emerging six weeks after Satoshi disappeared in April 2011.

The White House Council of Economic Advisers (CEA) released a study finding that banning stablecoin yield would boost traditional bank lending by only $2.1 billion, a 0.02% increase, with most of that benefit flowing to large banks rather than community lenders, and at a net welfare cost of $800 million. Even under extreme worst-case assumptions, the model produces only $531 billion in additional aggregate lending, a 4.4% increase relative to 2025 Q4 levels. The findings undercut the banking industry's argument that stablecoin yield poses a systemic threat, and arrive amid ongoing congressional debate over the GENIUS Act.

Polymarket will deploy CTF Exchange V2 over the next 2-3 weeks, introducing an optimized Order struct, EIP-1271 signature support for smart contract wallets, and builder codes that enable onchain order attribution. The platform is retiring USDC.e collateral in favor of Polymarket USD, a new 1:1 USDC-backed wrapper token. Frontend users receive automatic wrapping, but API traders and bots must manually wrap via the Collateral Onramp contract. Multi-language CLOB-Client SDKs in TypeScript, Python, and Go will handle the V1-to-V2 switch automatically, though bot operators must update their SDK version and re-sign orders using the new struct before cutover. All existing order books will be wiped during a short maintenance window, with the exact date announced at least one week in advance.

Tempo launched its Accounts SDK, letting developers add passkey-backed wallets to Wagmi/Viem apps via a single tempoWallet connector swap, with authentication handled through Face ID, Touch ID, or fingerprint, and no seed phrases or browser extensions required. The SDK ships with transaction simulation, fee sponsorship, batch transactions, and onramping, installable via accounts with multi-language examples on GitHub. The release is a rebuild of Porto on top of Tempo Transactions, designed for lower latency, reduced cost, and lighter integration overhead.

Brazil ranks 5th globally in both betting GGR and crypto adoption, processing $6-8B monthly with roughly 90% flowing through stablecoins across 25 million digital bettors. No regulated Brazilian platform currently offers prediction market-style contracts covering price discovery or non-sport events, creating a first-mover gap as new betting regulation takes effect. Gen Z crypto adoption grew 56% YoY, and online betting grew 135% YoY among users under 24, with a mobile-first user base that removes physical infrastructure costs from the equation. Brazil's combination of regulatory clarity, cultural familiarity with speculation rooted in the 1892 Jogo do Bicho lottery, and a $100B+ addressable market positions the country as a potential catalyst for prediction markets to move from a derivatives niche into a mainstream asset class.

x402, launched by Coinbase in May 2025 with roughly $0.0001 settlement costs on Base, has drawn production integrations from Cloudflare, Google, Stripe, AWS, and Visa, alongside $75B in USDC supply and sub-$0.001 L2 fees enabling sub-dollar payments for AI agents and micro-API businesses. Current adoption data reveals a volume gap: approximately 165M transactions have generated only $30M in cumulative volume over 10 months, with median payment sizes of $0.20 to $0.40 across roughly 3,900 active merchants. The payment rail mirrors TCP/IP in its value capture problem: x402 has no token, facilitators operate at roughly $5/month, and fee compression races toward zero, leaving the protocol itself thin for investors. Value accrues to settlement layers, orchestration platforms, and identity/trust infrastructure serving 70K+ onchain agents, with an $84T generational wealth transfer accelerating the move toward agents managing capital rather than executing isolated micropayments.

Prediction markets expose forecasting skill onchain but lack native capital formation mechanisms – copy-trading loses edge to execution lag and fund wrappers strip live signal, leaving no direct path for capital to back sharp traders. PredFi is a proposed financial layer built on three rails: allocation (direct capital formation around legible forecasters), collateral (pre-resolution positions treated as live economic value rather than capital trapped until settlement), and leverage (financial infrastructure forming around actively traded odds). The core reframe positions the event contract as a temporary container for a view, while the durable asset is the forecasting capability itself, specifically spotting mispricing, sizing conviction, managing exits, and repeating across cycles. The proposed end state is capital markets for judgment, where legible forecasting skill becomes something capital can organize around rather than passively observe.

Fewer than 20 tokens qualify as "investable," defined as projects achieving real business traction with tokenomics designed to capture value from that traction, placing assets like LINK and ONDO in a "project succeeds but token is irrelevant" quadrant despite undeniable protocol adoption. The three fastest-growing blockchain sectors, stablecoins, DeFi, and RWA tokenization, show minimal BTC correlation, yet exchanges, ETFs, and market makers have built their infrastructure around BTC trading, creating a structural disconnect between blockchain adoption metrics and broader token prices. Since the Iran conflict began on February 28, BTC has marginally outperformed gold and the Nasdaq, while most of the altcoin market remains lifeless, consistent with this mismatch. Gatekeeper adoption of token standards is a prerequisite for price action to reflect underlying adoption.

Ethereum dominates the tokenized commodities market with 95.9% market share, representing $5.1B in commodities tokenized on-chain.

Deposits for Aave V4 are growing at a similar pace to the initial V3 markets during their early phase.

South Korea's ruling Democratic Party proposed integrating tokenized real-world assets and stablecoins into the country's existing regulatory framework rather than drafting new legislation.

In Q4 2025, Europe, North America, and APAC (Australia, Japan, South Korea, and others) collectively led all regions at ~40% of RedotPay volume.
