TLDR Crypto 2026-03-30

Bill C-25, the Strong and Free Elections Act, introduced March 26, groups crypto alongside money orders and prepaid cards as difficult-to-trace payment methods and would prohibit their use for donations across the entire federal political system, including parties, candidates, and third-party election advertisers. The move, announced one day after the UK placed a moratorium on crypto donations, sharpens a growing regulatory split with the United States where the FEC has permitted crypto donations since 2014 and crypto-backed super PACs spent over $190M during the 2024 election cycle.

Washington's Attorney General sued Kalshi on March 28, alleging the platform operates illegal gambling products under state law, one week after Nevada secured temporary restraining orders against both Kalshi and Coinbase, requiring the removal of sports, election, and entertainment event contracts. Kalshi is asserting exclusive federal jurisdiction as a CFTC-regulated derivatives exchange, a position CFTC Chair Mike Selig has publicly backed. Legal experts expect the state-versus-federal jurisdictional conflict to reach the US Supreme Court, where the ruling will determine whether prediction markets face a fragmented web of state gambling bans or unified federal oversight.

Whop, the digital products marketplace with 18.4M users and $3B in annual creator payouts, launched Whop Treasury, offering up to 6% APY with no lockups, built on USDT0 on Plasma, yield routed through Aave via Veda vaults, MoonPay onramps, and Tether's Wallet Development Kit, with XAUT diversification available and BTC/ETH support planned. The product follows Tether's $200M investment in Whop at a $1.6B valuation, making Tether both a capital backer and the primary infrastructure layer across stablecoin issuance, wallet tooling, and tokenized gold.

A new Ethereum Improvement Proposal raises the maximum deployed contract code size from 24KiB to 64KiB and initcode from 48KiB to 128KiB, preserving the existing 2:1 ratio. The primary motivation is developer usability: fewer forced proxy and contract-splitting patterns, reducing complexity, deployment overhead, and potential attack surface from multi-contract architectures. The change requires a hard fork, with existing contracts remaining valid and unchanged, while only post-upgrade deployments can use the higher limits.

Agentic payments volume remains minimal today but is attracting significant capital, with the category crossing from theoretical to top-of-mind within the past year. Stablecoins are not the sole viable rail, as domestic use cases favor cheaper, faster fiat rails and card networks, pointing toward multi-rail orchestration as the winning architecture, while integrated stacks spanning identity, authorization, execution, settlement, and risk management are expected to outcompete point solutions. Regulatory compliance is underweighted across the space, with teams that cut corners facing shutdown risk within 18-24 months. Commerce may prove one of the later markets to adopt agent infrastructure rather than an early mover, as evidenced by OpenAI's rollback of Instant Checkout in ChatGPT.

With roughly 40 live agentic trading platforms competing across three distinct user profiles (abstraction-seeking normies, control-oriented retail traders, and data-driven quants), no single platform is expected to capture all three segments within the next year. As raw agent intelligence commoditizes, the durable moat shifts to distribution: embedding agents inside existing platforms where users already trade, such as Robinhood, Revolut, and IBKR. Scoped permissions (trade but not withdraw), onchain reputation systems measuring execution quality, and high-throughput chains are the prerequisite infrastructure for the sector to mature.

Whop's integration is one of the biggest DeFi-to-fintech deployments to date, with the digital products marketplace (over $1B in creator sales last year) building treasury yield, onramps, and tokenized gold directly into its platform via Aave, Veda vaults, MoonPay, and Tether's Wallet Development Kit. Whop solves the end-to-end creator monetization problem (build, sell, manage, and now earn yield on revenue), positioning it to become the largest fintech in its category.

Polymarket expands taker fees to nearly all market categories on March 30, adding politics, finance, economics, culture, weather, and tech to the existing crypto and sports markets, with only geopolitics remaining fee-free and the change applying solely to markets deployed on or after that date. Fees follow a dynamic curve that peaks at the 50% probability midpoint and tapers toward zero at the extremes, with crypto markets carrying the highest effective rate at 1.56% (targeting wash trading and HFT), while limit order makers pay nothing and receive daily USDC rebates. Analysts project $570K-$950K in net daily protocol revenue, annualizing to $209M-$342M, positioning Polymarket alongside Pump.fun (~$1M/day) and Hyperliquid (~$2M/day) among crypto's top fee-generating protocols off a base of ~$9.55B in 30-day volume.

Senator Elizabeth Warren wrote to Commerce Secretary Howard Lutnick, requesting internal documents and communications tied to Bitmain Technologies, asking what the department has done to address potential national security concerns around the Beijing-based mining hardware maker and whether Trump family business ties have influenced those decisions.

Analysts anticipate an early April launch.

Polygon CEO Sandeep Nailwal reports 159.9M stablecoin transactions last week, another all-time high.

The move positions Kalshi to compete for institutional capital that has historically favored derivatives venues with leverage capabilities.
