South Korea's Financial Services Commission missed the December 10 deadline for submitting won-pegged stablecoin regulation as tensions escalate with the Bank of Korea demanding veto power over issuance approvals and requiring bank-led consortia to hold 51%+ stakes in issuing entities. The FSC rejected both demands, citing a lack of global precedents and pointing to the EU and Japan, where fintech firms dominate issuance, while all cryptocurrency and stablecoin issuance remains illegal on South Korean territory. The ruling Democratic Party committed to introducing legislation by the end of January 2026, per President Lee Jae-myung's manifesto promises.
Jump Crypto's Firedancer client launched on Solana mainnet after three years of development and 100 days in production, written in C with modular tile-based architecture, demonstrating over 1 million TPS on commodity hardware versus the Rust-based Agave and Jito-Agave forks that historically dominated 95%+ of validators. The new implementation reduces single-client bug risk, threatening network liveness, as a hybrid "Frankendancer" client already captured 26% validator market share, signaling potential adoption trajectory. Firedancer uses low-level hardware access for fine-tuned optimization and splits validator tasks to run in parallel rather than monolithically, advancing Solana toward 1 million TPS goals alongside the proposed Alpenglow upgrade targeting 150-millisecond finality.
2025.12.16·links.tldrnewsletter.com·4 min read·TLDR Crypto Aave V4 introduces a hub-and-spoke liquidity architecture where liquidity is pooled in shared hubs and allocated to multiple spokes with distinct collateral and risk configurations. This allows new markets to launch using existing liquidity, making incentives far more capital-efficient and avoiding repeated bootstrapping from zero. Once a network establishes its first Aave V4 hub, that liquidity becomes reusable infrastructure for spinning up new markets, use cases, and expansions indefinitely.
a16z crypto's 17 predictions for 2026 center on stablecoins plugging into local payment rails and bank ledger upgrades from COBOL mainframes, crypto-native RWA perpification over skeuomorphic tokenization, and privacy becoming the most defensible moat, creating chain lock-in as bridging secrets is harder than bridging tokens. The firm expects Know Your Agent identity primitives to unlock agentic commerce, SNARKs hitting 10,000x overhead to enable real-time GPU proving for verifiable cloud computing, and secrets-as-a-service to provide programmable data access controls for institutions tokenizing real-world assets. Prediction markets will scale with AI agents as sophisticated traders and LLM oracles resolving contested outcomes, while crypto market structure legislation could eliminate legal distortions, forcing builders to optimize for cover over product strategy. Additional themes include staked media replacing claims of neutrality with verifiable commitments, decentralized quantum-resistant messaging eliminating private servers, and wealth management democratization through AI-personalized portfolios executing instantly on tokenized asset classes.
Ethena is countering Circle's ~$20M in profits from $4B+ USDC deployed on Hyperliquid by launching HyENA, a PerpDEX built on HIP-3 where USDe becomes the core trading collateral. Unlike USDC, USDe earns ~5% APY even while trading, routing value to users and LPs via yield, funding rates, market making, and liquidation fees. The strategy reframes stablecoins from extractive infrastructure to user-aligned financial primitives, positioning HyENA as a core Ethena product and a direct challenge to stablecoin-as-a-service models.
Cheap ETH swaps don't mean crypto is “done” scaling. Even Ethereum, Base, and Solana are nowhere near the throughput required for truly global, consumer-scale applications. A single viral app like HQ Trivia in 2018 handled ~2.38M concurrent users, implying a demand of ~238k TPS for a single trustless, verifiable, instant onchain experience, far beyond what any major chain can handle today without multi-hour settlement delays or extreme fees.
The real blocker for non-USD stablecoins isn't user demand for non-USD settlement, it's bank supply, constrained by post-2008 regulation that makes holding and market-making “non-reserve” FX inventory balance-sheet expensive, operationally messy, and capital-inefficient. As non-USD liquidity can be “trapped” by jurisdictional frictions and is treated as less stress-monetizable, banks rationally retreat to a USD hub-and-spoke model, leaving emerging market or non-major corridors in a structural liquidity vacuum. On-chain FX that depends on traditional bank market-making is structurally doomed, and non-USD stables need DeFi-native liquidity bootstrapping mechanisms.

Runway's GWM-1 is a world model that simulates physics and real-world behavior through frame-by-frame prediction. There are specialized versions for interactive environments (GWM-Worlds), robotics training (GWM-Robotics), and human avatars (GWM-Avatars). Runway positions GWM-1 as more general-purpose than competitors like Google's Genie-3, targeting applications in robotics, life sciences, and agent training. The company has also updated its Gen 4.5 video model to include native audio capabilities and long-form multi-shot generation, enabling users to create one-minute videos with consistent character and dialogue.
Designers often struggle with AI-prototyping tools because vague prompts produce cluttered, poorly organized interfaces with repeated elements, illogical content flow, and mismatched visual hierarchy. To improve results, use precise visual keywords, attach lightweight visual references or moodboards, conduct AI-powered visual analysis to formulate prompts, generate mock data for realistic content, and include code snippets from design systems. While these techniques enhance prompt specificity and output quality, they cannot replace the critical thinking and informed decision-making required for effective design work.
AI doesn't eliminate navigation in digital products but delegates it to invisible algorithmic agents that operate behind conversational interfaces, creating a "pharmakon"—a remedy and poison simultaneously. This delegation creates cognitive debt by removing formative practices such as searching, choosing, and discovering, while naturalizing algorithmic control under the guise of frictionless convenience. Meaningful resistance requires critical design therapeutics that preserve users' capacity for autonomous thinking, serendipity, and conscious engagement with tools that shape human cognition.
Amazon leverages dynamic pricing and deceptive interface design to influence buying decisions, including inflating reference prices to create the illusion of discounts. It also uses manipulative UX patterns in Amazon Prime sign-ups and cancellations that prioritize short-term gains over user trust, but such practices can harm brand value and increasingly carry legal consequences.

2025.12.16·go.clerk.com·Sponsor·TLDR Dev Developers can create secure-by-default features that integrate seamlessly into existing codebases by adhering to core design principles such as providing an API that closely resembles existing patterns, relying solely on public and stable APIs, and designing frameworks that cover broad bases rather than niche use cases. These design principles can be used to leverage AI to smoothly adopt frameworks at scale. The combination of thoughtful framework design and intelligent automation will be essential to protecting user data and maintaining trust at scale as code bases grow and security threats become more sophisticated.

An unsecured 16TB MongoDB database was discovered on November 23. The database contained 4.3 billion professional records, including LinkedIn-like data such as names, emails, phone numbers, job roles, employers, work histories, and social media accounts. It was secured two days after discovery, but prior access remains unknown. This exposed data could facilitate large-scale AI-powered social engineering, phishing attacks, CEO fraud, and credential stuffing by enabling automated personalized messaging and profile enrichment when combined with other breach data. Security teams should urgently monitor threat intelligence, improve email security to prevent AI-driven phishing, and train users to recognize advanced social engineering that exploits professional profiles.
A campaign attributed to likely Eastern European threat actors is distributing PyStoreRAT malware through GitHub repositories disguised as OSINT tools, GPT wrappers, and DeFi bots, using artificially inflated star counts and social media promotion to build credibility.

Four new phishing-as-a-service kits have emerged: BlackForce ($200-300, MFA bypass via Man-in-the-Browser attacks), GhostFrame (iframe-based evasion with 1M+ attacks), InboxPrime AI ($1,000 perpetual license with AI-generated emails mimicking Gmail behavior), and Spiderman (targeting European banks via Signal with OTP/PhotoTAN interception). These kits feature anti-analysis techniques, real-time credential exfiltration to Telegram, and spintax-based email variation to bypass signature detection. Organizations should implement phishing-resistant MFA, such as FIDO2, and monitor for the emerging Salty-Tycoon hybrid, which combines multiple kit techniques to evade detection rules.
A new group is running a phishing campaign that impersonates payment confirmations to trick finance-related staff into opening a ZIP file containing a malicious ISO image.
