MARKET INFRASTRUCTURE / TOKENIZATION

Circle named 11 founding validators for Arc L1

Circle named 11 founding validators for Arc, its Layer 1, ahead of a Sept. 16 mainnet launch: BlackRock, The Depository Trust & Clearing Corporation, Galaxy, Global Payments, ICE, Mastercard, MoneyGram, SBI Group, Standard Chartered, Sumitomo Corporation and Visa, per the cohort announcement. Circle's own disclaimer calls Arc “an open L1 blockchain … operated by a permissioned validator set”.

BlackRock is “expected to deploy” its BUIDL fund on the chain, and the DTCC leg; tokenizing assets custodied at the DTC, begins in the second half of 2027. Circle raised $222 million in an Arc presale at a $3 billion fully diluted valuation.

Our take: The seat is the product, the product is insurance

The Clearing House Interbank Payments System launched in 1970, owned by the New York banks that used it, and membership was the asset. What the eleven acquired today is a governance seat on a rail their own flows will settle over, plus first look at the integration roadmap. Visa and Mastercard both took one. That prices the seat as insurance.

PRIVATE CREDIT / RWA

Wellington and Nomura Put Credit Onchain

Sentora opened a Morpho lending vault against Wellington Management's first natively issued onchain credit strategy, taking deposits in PayPal's PYUSD. The vault held 9,6 million PYUSD against a 10 million cap on Aug. 6. Wellington, which manages more than $1.3 trillion, runs the strategy; Midas issued the token, mWIN, on Aug. 5; Northern Trust custodies it; the vehicle is a Luxembourg securitization compartment owned by an orphan trust.

Sentora chief executive Anthony DeMartino warned that “in extreme tail events, such as a global financial crisis or COVID style market shock, total return could turn negative,” and told holders to “size their leverage accordingly.”

Our take: Building demand is costly

The vault's net APY was 8.31%: strip the incentives and it was 0.70%, with a PYUSD-denominated reward stream paying 7.61% APR covering the difference.

Money-market funds ran a version of this play through the 1970-80s; sponsors waived fees and absorbed expenses to publish a competitive seven-day yield, then let the waivers roll off once the assets were sticky. The subsidy bought distribution, and it worked.

Wells Fargo will launch tokenized deposits for corporate and commercial clients this fall

Starting with one dollar-to-sterling corridor for selected clients and widening through 2027. The two segments Wells Fargo is targeting held $424.3 billion in average deposits last quarter. It is also one of 17 banks on The Clearing House's onchain rail, which targets the first half of 2027.

Cloudflare Gives AI Agents a Stablecoin Balance

Cloudflare launched Cloudflare Wallets on Tuesday, giving agents that run on its network a stablecoin balance and a human-readable handle at cloudflare.pay. It closes a round trip the company started a month ago: its Monetization Gateway lets sites charge agents per request over x402, and Wallets is the account those agents pay from.

Account Wallets belong to the humans who fund them; Virtual Wallets are issued per agent by API key and capped by allowance, allow list and maximum transaction size.

x402 has settled 160.6 million transactions worth $41.2 million across seven chains, per Agent Economy, about 26 cents apiece — a tracker that warns its own totals include tests and infrastructure traffic.

Western Union and Rain Launch a Stablecoin Card in 37 Markets

Western Union and card issuer Rain launched Stablecard on Aug. 4, letting people receive transfers as USDPT and spend the balance at any Visa merchant or ATM. Western Union moved $107.4 billion in principal across 285.9 million consumer transfers last year; USDPT, the Anchorage-issued Solana token it launched in May, has 7.4 million tokens outstanding. Rain framed the deal on X as “$100B a year for 100M customers” moving onchain; the product covers 37 of the more than 200 countries Western Union serves.

Dinari Opens 724 Tokenized US Stocks to Eligible US Investors

Dinari opened tokenized US equities to American investors on Tuesday, saying 724 stocks and ETFs can be bought with USDC from self-custody wallets. dShares are backed by the underlying securities in qualified custody and carry voting rights, cash dividends and execution at the national best bid and offer, with the US launch adding dividends paid natively in the stablecoin.

Access runs through Dinari Securities, and is limited to eligible investors under US securities law. The capabilities that would make a tokenized share behave differently from a brokerage share; continuous trading, T+0 settlement, collateralized lending and margin, are all filed under what the company says it could support “over time,” subject to regulators.

Mastercard Extends Crypto Credential to X-Border Stablecoin Payments

Mastercard and Borderless.xyz began a live pilot on Wednesday applying Crypto Credential, the network's verification system for digital-asset transactions, to cross-border stablecoin flows, with Infinia, Walapay and Koywe as the first participants. The target is compliance arithmetic: every new counterparty relationship in a stablecoin payment network triggers a fresh round of verification, so the work grows with the network. Each provider still runs its own KYC and KYB checks under local rules.

RWAs Topped Half of Hyperliquid's Volume

Perpetuals tied to stocks, indexes and commodities out-traded crypto pairs on Hyperliquid for two straight weeks in July, a first for the venue. RWA perps did $25.1 billion in the week of July 13–19, or 52% of the platform's $48.2 billion, per Blockworks, with single stocks making up 61% of that.

ARK's Lorenzo Valente calculated that Hyperliquid's RWA market alone is larger than every other DEX's crypto perp volume combined. The growth is also covering a decline; total quarterly volume has fallen from roughly $1 trillion in Q3 2025 to about $550 billion in Q2 2026, per Token Terminal.

Crypto card spending set a fifth straight monthly record

Spending capped $748.7 million in July, up 19.1% on June and 144.7% year over year, across 8.77 million transactions from 158,857 active addresses, per Paymentscan. RedotPay handled $395.1 million of it, and flows into stablecoin neobanks crossed $1 billion for the first time.

Nomura's Laser Digital took a stake in ZIGChain's token

Parties agreed to structure and risk-govern a pipeline of onchain private credit products with ZIG Markets, which has originated more than $50 million with no defaults over ten months. ZIGChain is targeting $25 million of total value locked by September and $100 million by the end of November. The products will reach retail as well as institutions — wider distribution than most tokenized private credit, which gates to accredited investors.
