Such an attack would not endanger mainnet funds. Any potential attack would only target “Sepolia,” where test ether has no meaningful cost, but could leave blocks without transaction payloads and derail the infrastructure testing needed before Glamsterdam reaches Ethereum itself.

What is Glamsterdam?

Glamsterdam is Ethereum’s next major upgrade, designed to fit more activity into each block without overwhelming the computers that verify it. Together with changes to gas pricing, the upgrade is intended to support a block gas limit of about 200 million, creating room for more payments and trades before users begin bidding fees higher.

The upgrade moves the relationship between validators and specialized block builders into Ethereum’s protocol. Builders assemble transaction blocks and compete to supply them. Once a validator accepts the winning bid, the builder is expected to reveal the underlying transactions.

And that process becomes easy to abuse on a free test network. A malicious operator can submit bids far above every legitimate builder, win repeatedly and then withhold the promised payload.

Developers said existing safeguards typically fall back to locally built blocks only after several payloads go missing.

Potuz added that clients also need to identify and reject individual builders so an attacker cannot return under a new identity and continue winning.

“Corporate treasuries were a big buyer through 2025, and they have stepped back,” Glassnode said. “Their average entry, the Corporate Treasury Cost Basis, sits at $80.5K, about 6% above spot, so the group as a whole is under water.”

Bitcoin topped that level recently but failed to keep gains.

Data source Bitcoin Treasuries now puts public-company holdings at about 1.22 million BTC across 181 listed firms. Strategy remains the dominant buyer and holder, with about 845,050 BTC. Tokyo-listed Metaplanet is among the next-largest corporate stacks. As a group, those treasuries are still underwater at current prices.

“A reclaim of $80.5K would put the treasuries back in profit and remove one layer of overhead supply; until then their entry is one more ceiling,” Glassnode added.

Other demand indicators paint a mixed picture

U.S.-listed spot bitcoin ETFs have attracted billions of dollars since early August, signaling a rebound in institutional demand for the cryptocurrency. However, they remain roughly $1 billion short of turning positive on a year-to-date basis, according to data source SoSoValue.

The Coinbase premium indicator has remained mostly negative since May, aside from a brief move into positive territory on Sept. 5, according to data from CoinGlass. A negative reading means bitcoin is trading at a discount on Coinbase relative to prices on offshore exchange Binance, suggesting that U.S. buyers are showing weaker demand than traders elsewhere.

World has launched World Money, a new self-custody financial “super app” designed to bring stablecoin payments and digital-asset features into one place. The rollout began Thursday across more than 150 countries, though specific capabilities are expected to vary by region, according to World.

The new app supports sending supported digital assets—including stablecoins—to recipients using a World username. It also allows users to deposit eligible assets to earn rewards and to buy and sell digital assets through exchange integrations. World further says the experience is built around its identity layer while giving users direct control of their funds.

Key takeaways

• World Money rolls out in over 150 countries, with feature availability dependent on location.
• Users can send supported assets (including stablecoins) via World usernames, not just blockchain addresses.
• The app adds third-party “Mini Apps” such as Kalshi, Credit and Morpho.
• A partnership with Stripe enables top-ups and stablecoin purchases with Apple Pay for users in the US.
• World splits its identity and financial functions across two apps: World ID App and World Money.

What World Money includes at launch

World positions World Money as a self-custody super app that combines multiple financial functions: transfers, trading access, and rewards on certain deposits. The company says users can send supported digital assets to a recipient’s World username, with stablecoins among the assets initially covered.

In addition to peer-to-peer transfers, World Money includes a rewards component. Users can deposit eligible assets to earn rewards, a feature that continues the direction World App previously took with earning opportunities tied to blockchain assets.

For trading, World Money provides buy-and-sell functionality through exchange integrations, giving users a way to switch between supported digital assets without leaving the app environment.

“Mini Apps” and payments onboarding through Stripe

One of the most visible expansions is World Money’s support for third-party mini applications. World says users can access Mini Apps including Kalshi, Credit and Morpho. This approach mirrors the super-app idea of bundling specialized services into a single interface, while relying on external platforms for specific product functions.

World also highlighted a payments onboarding partnership. According to the company, integration with Stripe allows users to fund their accounts and buy stablecoins with Apple Pay, starting with users in the United States. That matters for adoption because fiat-to-stablecoin entry points remain one of the biggest friction points for users who do not already hold crypto.

World did not describe whether Apple Pay support will expand beyond the US as part of this initial rollout, so users outside the US should expect different funding options depending on local availability.

How World is reorganizing its product stack

The launch is also a structural change. World says that with World Money, its identity and financial services are now separated into two dedicated apps: World ID App for identity verification and credentials, and World Money for the wallet, payments and other financial features.

Existing users of World App and World ID App can reportedly use their existing accounts for World Money, which should reduce the migration burden for current customers and limit the risk of fragmenting user identities and balances across platforms.

World Money is operated by Tools for Humanity, the company co-founded by Sam Altman and Alex Blania that builds technology for the World network. Tools for Humanity’s involvement aligns with World’s broader push to connect identity to financial actions rather than treating payments as a standalone feature.

From World App to a two-app super app model

World’s move comes after more than a year of incremental expansion of World App. World App originally launched in May 2023, bringing together World ID with a crypto wallet, stablecoin transfers and token trading.

In October 2024, World introduced World App 3.0, describing it as a “super app for humans” and adding third-party Mini Apps plus a Vault feature for earning on assets. That indicates World has been testing the combination of identity, custody tooling and app-level distribution of third-party services before splitting the experience into two apps.

Later, World also experimented with traditional banking rails. In November 2025, it piloted virtual bank accounts in the US, and then expanded the idea a month later. World says those accounts can support paychecks and bank deposits that are converted into USDC, illustrating an intent to reduce the steps between payroll and stablecoin holdings.

With World Money now separated from the identity layer, the ecosystem looks to be evolving from a single “do everything” client into a clearer division: credentials and verification in one app, and financial activity in another.

Why the split and rollout matter for users

For everyday users, the most practical change is likely the user experience: sending assets through a World username, accessing third-party services through Mini Apps, and using mainstream payment rails like Apple Pay via Stripe. Those elements can make crypto interaction feel less like dealing with addresses and more like using familiar app flows—especially when the stablecoin payment layer is integrated directly into the wallet experience.

For investors and builders, the strategic question is whether World can maintain trust and usability while expanding self-custody financial features across geographies. The company’s decision to run identity and financial services through separate apps may help scale compliance, product development and onboarding workflows without forcing users to navigate unrelated functionality in a single interface.

As World Money becomes available in more countries, the next watch item is how quickly Stripe-based onboarding expands beyond the US and how feature availability differs by region. Users should also pay attention to which assets are considered eligible for rewards and how the lineup of Mini Apps evolves after launch.
