If successful, this could make Base one of the most secure and compliant privacy layers in crypto.

Coinbase is preparing to make private stablecoin transactions possible on its Ethereum Layer-2 network, Base, according to CEO Brian Armstrong. The move could bring stronger privacy to public blockchains, where every transaction is visible.
Armstrong revealed the plan in a post on X (formerly Twitter), saying, “Base is building private transactions.” He added that Coinbase’s earlier acquisition of Iron Fish, a crypto privacy platform, was part of that mission.

While Armstrong didn’t address whether the new feature will require Know Your Customer (KYC) checks, he said more details will be released soon.
Why Privacy Matters in Crypto
Privacy has long been a tricky topic in the crypto world. Many users want the ability to keep their financial data private and protect themselves from hackers or scammers. Public blockchains, while transparent, make it easy for anyone to track wallet activity.
At the same time, governments have cracked down on privacy tools linked to illegal activity. Developers of Tornado Cash and Samourai Wallet have faced legal action, raising questions about how privacy can coexist with regulation.
How Iron Fish’s Tech Works
Iron Fish uses zero-knowledge proofs (ZK-proofs) and “view keys” to give users privacy while allowing them to share data when required. A view key lets someone, such as a tax authority, see transaction details without exposing all information publicly.

The Iron Fish system also connects through ChainPort, a bridge with real-time threat detection that blocks suspicious funds. It already supports privacy transactions on over 20 blockchains, including Base, and even offers a private version of wrapped USDC.

By bringing Iron Fish’s privacy tools to Base, Coinbase could help shape a middle ground, privacy with accountability. If successful, this could make Base one of the most secure and compliant privacy layers in crypto.

Coinbase is stepping into the world of agentic commerce with the launch of Payments MCP, a tool that allows AI agents to interact directly with the crypto economy.

This new framework gives popular large language models (LLMs) like Claude, Gemini, and Codex the ability to create wallets, access onramps, and make stablecoin payments—all without requiring API keys or developer setup.
With Payments MCP, AI agents can move beyond analysis and recommendations to take autonomous action in real-world economic contexts. Let’s discover more about Coinbase.
How Payments MCP Works
This release coincides with Coinbase’s broader push through the upcoming x402 Foundation, created in partnership with Cloudflare. Together, these initiatives aim to create a future where AI models can transact and participate in commerce on the same rails humans use. The system leverages the Model Context Protocol (MCP), which safely connects AI models to external tools and services. For Payments MCP, that means giving agents direct access to wallets, stablecoins, and the ability to complete transactions—all through natural language commands.

Payments MCP is designed to be user-friendly and secure. Agents can create wallets and sign in with just an email, eliminating complex setup. Users can also customize agent behavior through an intuitive interface, set spending limits. Also, manage transactions without touching code. The x402 Bazaar Explorer lets agents discover APIs and services they can pay for, while built-in onramps and guest checkout support fast, frictionless transactions. The system runs locally on desktops, enhancing speed and security.

A real-world example of this model is AI paying for cloud compute services or data subscriptions autonomously. Instead of a human manually buying compute hours or accessing paywalled datasets. An agent could handle the transaction in seconds. This approach aligns with a recent Gartner report, which predicts that by 2026, over 30% of IT tasks could be performed autonomously by AI agents. This highlights the growing demand for autonomous digital operations.

Bealls Inc., a 110-year-old U.S. retailer, is now the first national store to accept digital currencies from any crypto wallet across multiple blockchains.

The company announced a new partnership with Flexa, the global leader in digital payments, enabling customers to use popular digital currencies to shop in over 660 Bealls, Bealls Florida, and Home Centric stores across the United States.
The launch comes at a milestone moment for Bealls, which has built a reputation for embracing innovation while staying true to its family-owned roots. Now, the retailer is extending its legacy into the Web3 era, letting customers pay with assets ranging from bitcoin and ether to stablecoins and even meme coins, all within seconds.
A Historic Retailer Meets the Future of Payments
This integration is powered by Flexa Payments. It is a fast and secure platform that lets merchants accept over 99 digital currencies through more than 300 crypto wallets. What makes this technology stand out is its ease of use: customers simply scan a QR code at checkout. And, the payment is confirmed almost instantly. Flexa’s system integrates directly with existing retail infrastructure, so Bealls did not need to overhaul its operations to support crypto payments.
According to Flexa cofounder Trevor Filter, Bealls’ forward-thinking approach aligns perfectly with the evolution of commerce. “The retail legacy that Bealls has built over the last 110 years is simply incredible,” he said. “It’s no surprise that a company with this much staying power is now adopting one of the most important payment innovations the world has ever seen.”

The timing is fitting. Crypto payments are becoming more common in brick-and-mortar retail. A 2024 Deloitte survey found that nearly 75% of U.S. retailers plan to accept cryptocurrency or stablecoin within the next two years.

The 2025 MLB season has delivered high drama, and the World Series promises even more excitement as the LA Dodgers face the Toronto Blue Jays.

Now, the crypto trading platform dYdX is offering fans a new way to engage with the championship: prediction market-based perpetuals.
This innovative product lets users turn their knowledge of baseball into trades, creating a bridge between sports insights and financial markets.
Understanding Prediction Market-Based Perpetuals
Prediction market perpetuals are financial contracts that let users gain exposure to real-world events. In this case, the event is straightforward: will the LA Dodgers win the 2025 World Series? Market prices reflect the collective expectations of traders. If your prediction is correct, the contract settles at $1. If not, it drops close to zero.
These derivatives are unique because they combine elements of betting with professional trading strategies. For example, investors can apply perpetual leverage up to 5x, allowing them to amplify their potential returns while controlling exposure. Tools such as stop-loss and take-profit orders help manage risk, a feature missing in most sports betting apps. The market also offers real-time settlement tied directly to the World Series outcome, ensuring transparency and clarity for traders.

A real-world example comes from the recent NFL playoffs, where prediction markets for Super Bowl outcomes saw volumes exceeding $50 million in crypto. These markets allowed participants to trade on probabilities rather than simply betting, showing the growing appeal of narrative-driven financial products.
More About the Prediction Market
Jupiter has launched its first-ever Prediction Market, now live in beta and powered by Kalshi liquidity. The platform lets users trade on real-world events by choosing YES or NO for each market. Prices fluctuate based on supply and demand, and positions can be sold at any time before the market closes.

When the event concludes, each correct position settles at $1, while incorrect positions expire at $0, providing a clear and transparent way to turn predictions into potential gains.

Polymarket, a leading decentralized prediction market platform, has taken a step toward broader accessibility by launching its mini app in the World App.

This integration allows users to participate in Polymarket’s prediction markets directly through a familiar mobile environment.
To encourage engagement, Polymarket has partnered with the World Foundation to offer a 10 percent deposit bonus, up to 5 WLD (about five dollars), for eligible new deposits made through the mini app, with a minimum deposit of five dollars.
How the Mini App Works
Prediction markets allow users to place positions on the outcomes of real-world events. On Polymarket, participants buy and sell contracts representing a “yes” or “no” outcome. Prices change in real time, reflecting market consensus. At the conclusion of an event, correct positions settle at one dollar while incorrect positions expire at zero, offering a clear and transparent way to profit from informed predictions.
The mini app makes this process more intuitive. Users can deposit funds, explore markets, and trade positions without leaving the World App ecosystem. The partnership bonus provides an added incentive, effectively giving new users extra capital to start trading while learning the mechanics of prediction markets. This approach mirrors broader trends in fintech and crypto, where micro-rewards and gamified experiences are increasingly used to onboard new participants.

A real-world example can be found in the early adoption of Uniswap mini apps in mobile wallets. This will allow casual users to participate in decentralized finance with minimal friction. These integrations helped boost liquidity and broaden user engagement.
More About the World’s Ecosystem
