Mastercard Buys Its Way Into Stablecoins, and Uniswap Turns Idle Crypto Into Yield

Bitcoin and Ether both nudged higher this week without doing anything dramatic, even as a record-breaking data point suggests US institutions still aren’t fully back in. Underneath it all, a handful of larger-cap names are putting up the kind of moves the majors haven’t managed in weeks.

Market-Moving News

Three things worth your attention this week. A card network bought its way into stablecoins, Uniswap turned idle crypto into a yield product, and Bitcoin keeps trading cheaper on Coinbase than anywhere else.

Visa Adds Stablecoins to 18B-Endpoint Payout Network

Visa is bringing stablecoin prefunding and payouts into Visa Direct through a new infrastructure partnership with Zerohash. Eligible clients will be able to fund payment accounts with stablecoins and send stablecoin payouts directly to recipients.

Zerohash will provide the technical and regulatory stack connecting wallets, blockchains, compliance systems, and settlement. Visa Direct reaches more than 18 billion eligible cards, bank accounts, and digital wallets across over 195 countries and territories.

Stablecoins Move Inside Existing Rails

Businesses traditionally hold fiat balances in advance to ensure cross-border payouts can be completed. Stablecoin prefunding allows clients to move digital dollars into Visa Direct around the clock instead of waiting for banking systems to open or transfers to clear. Recipients can also receive stablecoins directly when the service is supported.

The partnership does not activate stablecoin payouts across all 18 billion endpoints immediately. Access will depend on client eligibility, local regulations, and supported wallets.

Distribution Becomes the Advantage

Stablecoin companies have spent years building separate payment networks. Visa is taking another route by adding onchain money to infrastructure already used by banks, fintechs, and payment companies.

Zerohash operates regulated entities across major markets and supports dozens of blockchains and stablecoins. Visa has not yet disclosed which specific assets and networks will be available through this integration.

Take: The next test for you is whether stablecoins become a regular funding tool inside Visa Direct rather than a limited payment option. Real adoption begins when businesses use the service for recurring cross-border flows at commercial scale.

World Chain Streams Block Data Every 200ms

World Chain will activate streaming Block Access Lists on August 17, becoming the first production Layer 2 to send full EIP-7928 data while blocks are still being built.

Its Flashblocks system divides each two-second block into updates delivered about every 200 milliseconds. Validators can begin checking transactions immediately instead of waiting for the finished block.

World Chain is targeting throughput of up to one gigagas per second, equal to one billion gas units.

Validators Get the Map Early

Block Access Lists record the accounts, contracts, and storage locations touched during execution, along with resulting state changes. The map shows which transactions depend on each other. Independent activity can be checked across multiple processor cores, reducing the sequential workload that slows block validation.

EIP-7928 can also support parallel disk reads, state-root calculations, and updates without re-executing every transaction.

Speed Faces a Production Test

World says testnet validation latency remained largely stable as throughput increased, suggesting faster networks may not require validators to buy stronger machines. The result is not guaranteed on mainnet. Heavy traffic, larger access lists, bugs, or network delays could create bottlenecks that controlled testing missed.

World Chain is enabling the feature through a runtime setting. Ethereum’s base layer has not adopted EIP-7928, which remains under review.

Take: The upgrade puts one question in front of you: can World Chain raise throughput without forcing validators into a hardware arms race? August 17 will show whether streamed verification survives production traffic.

Binance Affiliates Seek $473M From RedotPay Founders

Three Binance-affiliated companies are seeking $472.8 million from RedotPay’s co-founders in a Hong Kong lawsuit involving more than 470,000 crypto-card users.

Nest Trading, Distributed Technologies, and Chaintecs Consulting Singapore allege Gao Zhangpeng, Chan Wa Choi, and Yao Chao breached a 2025 agreement. The complaint claims RedotPay let customers fund its cards through Binance Pay in ways that redirected business from Binance Card.

RedotPay says the proceedings do not affect operations and that it is vigorously defending the claims. No court has ruled that the founders breached the agreement.

Customer Access Gets a Price Tag

The plaintiffs calculate their alleged losses at about $925 per customer. The figure shows how valuable distribution has become in crypto payments. Exchanges and card providers are no longer competing only on fees or supported tokens. Access to an established user base can decide which platform captures everyday spending.

The Dispute Reaches Beyond Damages

RedotPay has explored a U.S. listing that could raise more than $1 billion at a valuation above $4 billion. A $472.8 million claim may complicate investor reviews even if the company defeats it. The central question is whether RedotPay grew through permitted access or crossed restrictions inside the Binance agreement.

Take: The lawsuit gives you a hard number for what crypto companies believe payment customers are worth. Its impact will depend on whether the court sees RedotPay’s expansion as competition or a breach of contract.

One top fund manager put more than half of a $9 billion portfolio into a single little-known company.

Then his firm kept buying for 61 straight trading days. Now, with Washington moving to protect critical mineral supply chains through Project Vault, Whitney Tilson says
this company could be sitting on one of America’s most strategic assets.

Crypto Know-How: Why Owning the Rails Beats Renting Them

Mastercard's BVNK purchase is the largest acquisition a major card network has made in the stablecoin space to date. It's bigger than Stripe's $1.1 billion buy of Bridge last year, and it makes Mastercard the first big card network to own stablecoin settlement infrastructure outright rather than just plug into someone else's.

Here's why that distinction actually matters to you. A partnership means a company is renting access to another firm's rails, and it can walk away or get outbid. Ownership means Mastercard controls the roadmap, the pricing, and who gets access next.

When Visa announced its own stablecoin settlement pilot with Stripe's Bridge around the same time, it was the clearest sign yet that both of the biggest payment networks in the world now see stablecoins as core infrastructure, not a side experiment. The company that owns the rails usually ends up writing the rules everyone else has to follow.
