TLDR Crypto 2026-03-13

Across Protocol put forward a first-in-crypto proposal to dissolve the ACX token structure entirely, offering a token-to-equity exchange at a 1:1 ratio with uniform share class across employees, investors, and public token holders. The stated rationale is that the token structure actively impedes enterprise BD – particularly with tier-1 crypto projects and traditional financial institutions – by forcing agreements to route through a foundation. On the product roadmap, Across is positioning "free bridging" as the inevitable standard for stablecoin issuers by end-of-2026, with the model already live with Native Markets for USDH and two additional undisclosed deals in the pipeline. Longer-term, the team is framing Across's intents-based architecture as foundational infrastructure for agentic payments.

Ripple is repurchasing $750 million in shares from investors and employees, valuing the firm at $50 billion. Following $100 billion in payment volume, the company is expanding into stablecoins and infrastructure via acquisitions like Hidden Road, signaling a strategic pivot away from immediate IPO plans.

Circle ran a controlled experiment allocating $30,000 in USDC to AI agents tasked with autonomously operating a hackathon, resulting in 204 project submissions, 1,352 valid votes, and over 9,700 comments. Agent behavior ranged across a wide spectrum: some delivered functional products, others disregarded instructions entirely, and a subset attempted collusion – surfacing concrete alignment and trust risks in autonomous financial systems. Circle published new research alongside the results, framing the experiment as evidence that the agentic economy requires formal guardrails before deploying agents with real capital authority.

The x402 protocol utilizes the HTTP 402 status code to enable machine-to-machine payments via USDC on Base. Supported by Cloudflare and Google, it facilitates sub-cent API transactions. This eliminates subscription overhead, allowing AI agents to autonomously purchase data and services without human intervention.

LMSR (Logarithmic Market Scoring Rule) is the automated market maker backbone of Polymarket, solving the thin-liquidity problem that renders traditional order books unworkable for niche prediction markets by having the protocol itself always quote prices. The pricing mechanism is mathematically equivalent to the softmax function used in neural network classifiers, guaranteeing that all outcome probabilities remain valid and sum to 1.0 regardless of trade flow. The liquidity parameter b directly bounds market maker loss at b x ln(n), capping the subsidy needed to bootstrap liquidity – a binary market with b=100,000 carries a maximum loss exposure of roughly $69,315. For traders, edge is formally quantified but sequential self-induced price impact degrades average fill quality, meaning position sizing must account for both informational conviction and effective market depth.

Reported AI agent payment volume via x402 is significantly overstated: Bloomberg cited $24M over 30 days, but Allium onchain data pegs the figure at ~$3M, and applying a wash trade filter developed by Artemis Analytics reduces the honest number to $1.6M. Current activity is concentrated in developer tooling – web scraping, browser sessions, image generation, and data enrichment – where x402's pay-per-query model lets agents access services without subscriptions or accounts. Despite the modest volume, infrastructure investment signals long-term conviction: Coinbase built x402, and Stripe, Cloudflare, Vercel, and Google have since integrated it, positioning for a future where agents are the default buyer. The article itself cost $0.47 to research using Allium's x402 endpoint.

Weekly crypto code commits dropped 75% to 210,000 since 2025, while AI-related repositories increased 178%. Major networks like Ethereum and Solana lost over 30% of active contributors. This talent migration toward AI infrastructure leaves blockchain development increasingly reliant on a smaller pool of veteran contributors.

Analysts from a16z and Artemis reveal that 81% of x402 transaction volume is artificial wash trading. While x402.org reports $24 million in monthly volume, Artemis data shows less than $2 million. These discrepancies highlight early-stage measurement challenges despite infrastructure support from Stripe, Google, and Cloudflare.

Luxor estimates that only 8% to 10% of the global Bitcoin hashrate, primarily in Gulf states like the UAE and Oman, is sensitive to oil prices.

PropAMMs (Proportional Automated Market Makers) represent one of the most significant advances in market microstructure in potentially decades.

Prime brokers are beginning to offer hedge funds and institutional clients access to Kalshi's event contracts, marking a notable step toward mainstream Wall Street adoption of prediction markets.

Kraken released the Kraken CLI, an open-source, single-binary execution engine providing AI agents and developers with direct, native access to crypto markets.
