Block is assembling the pieces to become a full payment network rivaling Visa/Mastercard. It already has millions of Square merchants and 60M+ daily Cash App users, and its new "Neighborhoods" feature can route payments directly between Block-owned accounts via Cash App Pay, bypassing card networks and charging just 1% while still profiting. Future phases could extend Cash App Pay to non-Square merchants (leveraging fraud data from Cash App's user base) and eventually make it an official debit network accepting all cards, positioning Block as a genuine fifth payment network.

New Jersey argues states retain authority over gambling law, and Kalshi says it can't be regulated by "50 different regulators." This comes amid a broader nationwide fight between states and the CFTC, which claims exclusive jurisdiction. Kalshi recently lost a related case in Nevada at the Ninth Circuit.
2026.09.04·links.tldrnewsletter.com·2 min read·TLDR Crypto Bitcoin's 90-day correlation with gold hit its highest level since 2020 during the latest Treasury bond selloff, with bitcoin gaining 22.4% in a week, as yields rose and the dollar weakened. Bitwise frames this as bitcoin trading like "amplified gold" amid currency-debasement fears. Bitcoin's correlation to the S&P 500 fell toward zero over the same period, but similar equity decouplings during bond selloffs have historically been short-lived rather than structural. Bitcoin has since pulled back from an $80K+ peak to around $77,600, with long-term holder supply clustered between $83K-$86K and an accumulation floor around $62K-$65K.

Hey Anon released Build 3.0, a ground-up rebuild of its DeFAI app centered on a modular protocol-selection layer that scopes AI agent access by user role: yield farmers can enable Aave, Yearn, Beefy, and Pendle; perps traders can select Hyperliquid, Jupiter, or Aster; and token deployers get Pumpfun and Raydium. The update overhauled the dashboard with editable widgets, added agentic wallet creation at sign-in, and split the research AI (Gemma) into a separate chat interface distinct from the main Anon agent. Background task execution was removed in favor of in-conversation processing, reducing agent operational footprint, while coverage spans TON, Solana, and 18 EVM networks. A mobile app is pending Apple review, and a browser extension and AI trading terminal are on the near-term roadmap.
2026.09.04·links.tldrnewsletter.com·3 min read·TLDR Crypto Wintermute categorizes RWAs as crypto's next structural liquidity channel, following VC/ICO, stablecoins ($120B net issuance in a single year), and ETFs/DATs ($63B net flows plus $115B treasury accumulation), noting that onchain tokenized value has tripled to ~$30B even as the stablecoin base contracted. At 18 months of age, the RWA channel shows trailing-12-month inflows of 0.9% of market cap, tracking ahead of DATs and just behind ETFs at the same stage. Prior channels delivered asset-specific buyers, while tokenization places capital inside the system, where purchases of tokenized Treasuries or equities can rotate into BTC or alts with reduced friction, aided by tokenized assets now being accepted as collateral across major venues and DeFi protocols. If historical timing holds, peak RWA inflows are still 2 to 3 years out, and balance-sheet holders as the dominant cohort suggest the resulting cycle runs longer and with less volatility than prior ones.
2026.09.04·links.tldrnewsletter.com·5 min read·TLDR Crypto Global remittance fees average 6.36% against a 3% UN 2030 target, and stablecoins address only the cheapest of three pipeline segments: a Dubai-to-Manila transfer uses a blockchain in 1 of 6 steps, with the remaining steps requiring FX working capital, compliance, local licenses, and payout rail access. Tokenized liquidity does reduce one structural friction: correspondent banking locks capital per country, while on-chain pools can rebalance across 50 markets in minutes rather than days. Félix Pago's $200M raise for US-to-Latin America USDC transfers via WhatsApp demonstrates that even free-distribution consumer apps still require a balance sheet to operate. Stablecoin fragmentation introduces a new correspondent layer, as Circle, Tether, Stripe Bridge, Sony, Klarna, Cloudflare, and Fiserv stablecoins don't interoperate cleanly, prompting a16z Crypto to lead a $10M round into Better Money for cross-stablecoin conversion, replicating on-chain the same intermediary function blockchains were meant to remove.

Goldman Sachs, Bank of America, and several other major financial institutions in the US are forming a consortium to jointly issue a dollar-backed stablecoin, targeting a 2027 launch. The collaborative model suggests the banks aim to share infrastructure costs and regulatory compliance burdens rather than build competing products in parallel. A coordinated TradFi entry from systemically important institutions would put the product in direct competition with USDT and USDC, which together account for the majority of global dollar stablecoin supply. The move reflects broader bank momentum toward stablecoin rails as US federal stablecoin legislation has provided clearer issuer requirements and institutional on-ramps.

Real-economy stablecoin payments were only about $390B in 2025, and B2B accounts for ~$226B of that, dominated by USDT and driven by small and mid-sized importers, not crypto-native firms. Asia is the current volume center, LATAM shows strong institutional B2B rails despite a declining US-Mexico remittance corridor, Africa is the least-served and highest-margin region due to thin payout coverage, and MiCA rules make EU-touching corridors route around USDT. Infrastructure is consolidating fast into incumbents, leaving genuine white space only in Africa payouts, intra-LATAM, Turkey/CEE, and mid-market Asia sourcing: corridors with the widest cost gap and the thinnest coverage.
2026.09.03·links.tldrnewsletter.com·6 min read·TLDR Crypto Argentina's stablecoin adoption traces to a 2001 banking crisis in which the government froze deposits and forcibly converted dollar accounts to pesos, wiping out roughly three-quarters of the peso's dollar value, with usage accelerating after 2019 capital controls capped official dollar purchases at $200/month. Today, 94% of peso crypto trading flows to stablecoins, the highest share of any major currency Artemis tracks, while downloads of the country's top 15 crypto apps rose 93% in 2024 and 1 in 5 Argentines now use crypto. After Argentina lifted most capital controls in April 2025, the official and parallel exchange rates converged to within ~4%, removing the structural arbitrage that originally made stablecoins essential for dollar access. Lemon wallet downloads climbed each quarter even as monthly inflation fell from 25.5% to 2.1%, and USDC contractor payroll share leveled off rather than dropped, indicating stablecoins have shifted from crisis hedge to standing financial preference.

Crossmint routes these transactions as "digital goods/media" rather than crypto purchases, a classification that bypasses standard credit card network crypto restrictions and qualifies buyers for rewards points or cash back they would not earn on a properly coded crypto transaction. Chase flagged the Visa transactions as incorrectly classified and has asked Visa to investigate, while the New York Attorney General's Office confirmed it is reviewing the matter. Crossmint has defended its classification approach as scrutiny from both a major bank and a state regulator mounts.
Robinhood Chain's daily fees doubled to $2.13 million, sending ARB up 25% to $0.1087 as the Arbitrum DAO's 10% licensing cut translates to roughly $192,000 per day at current rates. Chain DEX volume climbed 89.5% weekly to $1.56 billion, and TVL reached $738.5 million, though memecoin speculation rather than tokenized equity trading drives the bulk of that activity. The move lifted adjacent tokens across the L2 and DeFi sector, with CRV gaining 14.1% and OP rising 13.9%, while Bitcoin held near $78,000 and total crypto market cap stood at $2.72 trillion. ARB remains 95.5% below its January 2024 peak of $2.39, placing market cap at roughly $726 million despite the week's gains.

Ethlabs' Week 10 update covers three Hegotá hard fork workstreams across account abstraction, block time reduction, and fast finality. EIP-8141 (Frame transaction), a platform primitive enabling custom authentication schemes, spend-policy enforcement, and ERC20 fee payments, received "Scheduled for Inclusion" status for Hegotá, the strongest approval signal from Ethereum core developers, alongside the complementary EIP-8130 turnkey wallet interface. The team is advocating for a first block time cut from 12 to 10 seconds in Hegotá, framing the fork as the last practical window before a multi-fork delay to begin the chain's transition infrastructure for lower block times. Researchers shipped pseudocode formalizing all components of decoupled consensus, which separates finality from block production and is slated for the I* fork following Hegotá, where formal verification work is already producing small protocol adjustments on the path to reducing finality from the current ~15-minute average to a few minutes.

The proposal doubles the annual disinflation rate from 15% to 30%, removing approximately 18.9 million SOL from future emissions over six years and pulling Solana's 1.5% terminal inflation floor forward from 2032 to mid-2029. Kraken's primary validator switched from opposition to roughly 90% support six hours before voting closed, shifting ~8.1 million SOL, though the proposal would have passed at 69.4% support even without the reversal. Staking infrastructure operators Figment and Everstake voted against, as first-year yields fall from 4.93% to 4.34% and projections show 30 validators becoming unprofitable by year three, while ecosystem developers Helius and Jupiter supported the measure.
Aave spent 2026 assembling the pieces of a full-stack bank. These include V4's hub-and-spoke architecture (live since March, non-rebasing ERC-4626 accounting for institutional legibility), consumer product acquisitions (Family wallet and Stable Finance) folded into the Aave App (up to 9% deposit yield), Stable Vaults as white-label B2B yield infrastructure, Horizon's institutional RWA lending book (~$570M, targeting $1B+), and GHO stablecoin issuance (~$600M circulating). Aavenomics 3.0's non-discretionary token buyback (funded by DAO net revenue, ~$134M annualized) is converting all of this into direct AAVE supply reduction, meaning the token is mispriced.
2026.09.02·links.tldrnewsletter.com·6 min read·TLDR Crypto EIP-7999 creates separate gas markets for execution, data, and state, but these markets are coupled through block-level access lists that data gas prices and execution activity jointly generate. An Ethereum Foundation internship analysis constructs a joint equilibrium model, finding that a 300M execution gas target requires approximately 77M data gas target, consuming 85.5% of the 90M data cap under reference calibration and leaving minimal headroom. Execution elasticity is the dominant sensitivity parameter: a 1% relative reduction raises the required data target by 7.1%, and a 1.98% reduction pushes requirements past the hard 90M data limit. When data targets fall below the calculated thresholds, execution base fees compress to the 1 wei floor and execution markets underfill despite correct configuration, a failure mode that dynamic simulations may confirm persists long-term.
The ether.fi crypto card serves different user types. ETH holders can borrow against staked ETH without selling (~55% LTV via Aave v4), IT workers get 3% cashback on subscriptions via virtual cards, AI users get higher cashback on Anthropic/OpenAI bills via a referral code, freelancers route client USDC through a vault with a ~$30K daily cap, founders get tiered virtual cards for business spend, travelers get Visa Signature perks and up to 5% back at partner hotels, and privacy-focused users get a non-custodial vault (KYC still required, but no custodial fund control by the company).
OpenAI ($852B post-money, $40B ARR) and Anthropic ($965B post-money, $65B ARR) are each priced on a winner-take-all infrastructure thesis that mirrors how crypto VCs funded L1s last cycle, when the prevailing assumption was that the fastest, most capable layer would capture the bulk of economic value. Routing abstractions are eroding that logic: OpenRouter aggregates 400+ models from 80+ providers behind a single API, Stripe has agreed to acquire it, and DeepSeek's share of platform token volume doubled from 9% to 18% in six months, converting model selection into a per-task price and latency optimization. The Polymarket/Polygon split shows where value actually settles once infrastructure commoditizes, with Polymarket retaining $15.3M in protocol revenue over 30 days against $2.1M for Polygon's base layer, a 7.3x gap that reflects customer ownership residing with the application, not the chain underneath it.

2026.09.01·links.tldrnewsletter.com·2 min read·TLDR Crypto A researcher has published a point-by-point defense of their Poseidon2b hash function implementation for potential use in Ethereum, asserting it holds against the recently published "Skipping Class" algebraic attack. The paper's exploit targets state widths t=12-24 using a tensor MDS construction. The production instance runs t=4 with a complete external MDS layer, placing it outside the attack's scope. The best published cryptanalysis of the specific parameters (GF(2^128), x^7 S-box, 8 external/58 internal rounds) projects attack work at approximately 2^410, well above the 128-bit security target. The researcher backs the claim with pinned source code and executable audits, inviting targeted cryptanalysis of the exact configuration rather than generalized arguments about Poseidon as a family.
Techtree is a controlled evaluation platform from Regents Labs that isolates a single variable (the Skill) across a fixed model, harness, runtime, tools, and budget to produce evidence of whether an agent improvement is real. Each evaluation run outputs a signed, participant-attested proof bundle verifiable offline, solving the trust problem of accepting another agent's benchmark results without rerunning the eval. The v0.2 roadmap introduces "Environment Forge" to convert source evidence (chat logs, traces, and repositories) into qualified verifier environments, with later versions gating receipt access behind x402 payments and feeding forged environments into RL training via prime-rl. The longer-term plan opens improvement markets for Skill Climbs and Harness Climbs with onchain reputation for authors, building credibility rails for agent skill development and deployment.
2026.09.01·links.tldrnewsletter.com·5 min read·TLDR Crypto Coinbase launched four tokenized equity tokens (NVDAc, METAc, AAPLc, and GOOGLc) on Base for non-US users, built on B20, a Base-native standard for compliant onchain asset issuance. B20's multiplier system handles corporate actions by updating a single onchain value rather than rewriting ERC-20 balances, keeping AMM pool reserves unchanged during stock splits and dividends and preserving DeFi liquidity. A shared Policy Registry propagates compliance updates such as sanctions blocklists to every asset referencing it, and administrators holding the seize role can move tokens from flagged addresses to authorized destinations with onchain memos recorded atomically. The launch generated $10.8M in 24-hour volume and $3.06M in DEX liquidity across ~50 protocols including Aave, Morpho, and Aerodrome, as the tokenized public equities sector reaches $2.48B total with Ondo leading at $872.7M.
2026.09.01·links.tldrnewsletter.com·5 min read·TLDR Crypto Strategy holds 840,447 BTC at an average cost basis of $75,653, with Bitcoin trading near $79,007, placing the position roughly $2.8 billion (4.4%) in profit after a two-month acquisition pause. The firm has begun selling modest BTC quantities to fund preferred dividends and share buybacks, a departure from its longstanding "never sell" policy, while also raising $334 million via MSTR stock sales to preserve reserves. Saylor's Sunday post of a chart captioned "We're Back" has renewed speculation about an imminent purchase announcement, consistent with his pattern of social media signals preceding Monday morning buys. Fed Chair Kevin Warsh's inflation-driven rate-hike comments pulled Bitcoin to $76,877 by Friday, keeping Strategy's unrealized gain thin relative to the asset's October peak near $126,000.
MEV-X researchers and HSE University collaborators introduce "dislocation value," the total extractable profit when an AMM pool price diverges from the market, and demonstrate that any fee levied on arbitrage trades reduces total value capture across all six tested architectures, including Uniswap V2/V3, Balancer, and Curve. Pools optimizing fee revenue independently capture roughly 50% of maximum dislocation value, with the remainder split between external arbitrageurs and unrealized losses. At the standard 0.30% fee tier, pool capture falls to 42% on a 1% dislocation scenario. The proposed fix is AMM hooks that execute atomic internal arbitrage post-swap, letting pools charge zero on rebalancing operations while retaining normal retail fees and eliminating external searcher profit. This architecture converts liquidity providers into active arbitrageurs at the protocol level, redirecting the value leakage currently flowing to external searchers back to the pool.
A Public Citizen report tallies investor losses across Trump-linked crypto ventures at a minimum of $4.7 billion in 2025, against at least $1.4 billion Trump earned from the same projects. The TRUMP memecoin drives $3.2 billion of those losses. Roughly 1 million of 1.6 million retail buyers on decentralized exchanges remain underwater after the token fell from a $73.43 peak to approximately $2.73, with wallets from the first two trading days capturing nearly 90% of all retail-side gains. World Liberty Financial contributed $1 billion in additional losses, led by AI Financial Corp's $1.46 billion WLFI token purchase in August 2025, which left the Nasdaq-listed firm's stock down 91% to $0.642, while Trump Media's 9,477 BTC position accounts for another $450 million in losses. Trump's tokens were allocated rather than purchased, and his income flowed through licensing fees, meaning he deployed no capital while retail holders absorbed the drawdown.
