RWA Weekly: Coinbase Announces Launch of Prediction Markets and Tokenized Stocks; Stablecoin U Goes Live on BNB Chain and Ethereum

RWA Weekly Roundup: Coinbase Launches Prediction Markets and Tokenized Stocks; Stablecoin $U Debuts on BNB Chain and Ethereum The on-chain RWA market cap rose slightly to $18.9 billion, while stablecoin market capitalization exceeded $300 billion, though transaction activity declined, indicating a "stagnant liquidity" phase. Regulatory developments accelerated globally, with China promoting the digital yuan, and the U.S., Canada, and Hong Kong advancing stablecoin and asset tokenization frameworks. Traditional financial institutions expanded their involvement: JPMorgan launched a tokenized money market fund on Ethereum and integrated JPM Coin with Base, while Visa and Mastercard extended stablecoin payment services. DTCC partnered with Canton Network for U.S. Treasury tokenization. Coinbase introduced prediction markets and tokenized stocks, PayPal launched a PYUSD savings vault, and SoFi issued its own stablecoin, SoFiUSD. Emerging markets like Brazil and Pakistan also explored sovereign asset tokenization. Stablecoin $U went live on BNB Chain and Ethereum, integrating with DeFi protocols like PancakeSwap and ListaDAO. Despite growth, JPMorgan analysts caution that stablecoin market size may not reach $1 trillion by 2028, projecting a more moderate expansion to $500-600 billion. The sector continues to evolve, driven by regulatory clarity and institutional adoption, embedding RWA deeper into global payment and asset management systems.

How Does x402 V2 Enable Autonomous Payments for AI Agents?

The x402 protocol, initially developed by Coinbase, leverages the HTTP 402 status code to embed payment logic directly into web requests. The newly released V2 upgrade introduces significant improvements to address limitations in cross-chain support, scalability, identity authentication, and repeated payments experienced in V1. Key enhancements include: - **Wallet Identity and Reusable Sessions**: Supports wallet-based authentication (e.g., Sign-In-With-X via CAIP-122), allowing reusable sessions after initial payment. This reduces latency and costs for high-frequency use cases like AI agent tasks and LLM inference. - **Unified Payment Interface**: Enables multi-chain payments (e.g., Base, Solana) and compatibility with traditional systems (ACH, SEPA, credit cards) via Facilitators. Dynamic payTo routing allows context-aware pricing and complex market structures. - **Modular Architecture**: A plugin-driven SDK simplifies integration, supporting easy expansion to new chains and payment methods without core changes. Multi-Facilitator support automates optimal payment path selection based on preferences. - **Automatic Discovery**: Services can expose metadata for automatic synchronization, ensuring real-time pricing and availability updates without manual intervention. For end-users, V2 enables seamless, subscription-like access with reduced friction. Developers benefit from flexible, low-maintenance payment integration and dynamic pricing models. AI agents gain autonomy to make economic decisions, such as purchasing API calls or compute resources independently using allocated budgets. x402 V2 evolves from a pay-per-use tool into a versatile economic layer, though challenges like ecosystem adoption, modular risks, and regulatory uncertainty remain.

x402 V2 Released: What Are the Core Highlights?

The x402 protocol, initially developed by Coinbase, has now released its V2 upgrade. The core idea remains leveraging the HTTP 402 status code to embed payment logic directly into web requests. Since its launch, x402 has processed over 100 million payments across various use cases, such as API calls and AI agents purchasing compute resources. V2 introduces several major improvements. It supports wallet-based identity (e.g., Sign-In-With-X via CAIP-122) and reusable sessions, allowing users and autonomous agents to avoid repeated on-chain payments after initial authentication, significantly reducing latency and cost for high-frequency interactions. A unified payment interface now supports multiple chains (including Base and Solana) by default and integrates traditional payment rails like ACH and credit cards through Facilitators. Dynamic payTo routing enables complex pricing models and multi-tenant setups. The architecture is now modular and plugin-based, making it easier for developers to extend support for new chains or payment methods without altering core SDK code. Configuration is simplified, with automatic optimization based on developer preferences. A new discovery mechanism allows services to publish structured metadata, which Facilitators can automatically index, ensuring pricing and endpoint information stays current without manual updates. For end-users, V2 enables seamless, near-invisible payments with a "micro-subscription" feel. Developers benefit from reduced integration effort, dynamic pricing capabilities, and more flexible business logic. AI agents can autonomously transact using endowed wallets, making independent economic decisions. Overall, x402 V2 evolves from a pay-per-use tool into a versatile economic layer for the internet, though widespread adoption, modular risks, and regulatory challenges remain.

Interop Roadmap Accelerates: After Fusaka Upgrade, Ethereum Interoperability May Take a Key Leap

Recent Ethereum Fusaka upgrade, while primarily focused on Blob capacity expansion, introduced the underappreciated EIP-7825, a critical enabler for Ethereum's zero-knowledge (ZK) and interoperability roadmap. This proposal sets a hard per-transaction gas limit (~16.78 million gas), preventing "mega-transactions" from monopolizing a block. This change transforms block proof generation from a sequential logic problem into a parallelizable computational task, making real-time ZK proofs an engineering feasibility rather than a theoretical impossibility. This foundational shift is pivotal for the L1 zkEVM vision, where Ethereum itself generates verifiable proofs for its state transitions. L1 zkEVM acts as a universal "trust anchor," allowing Layer 2s (L2s) to instantly and trustlessly verify the mainnet's state without waiting for challenge periods. This eliminates the speed-trust decentralization trade-off, enabling near-instant, decentralized cross-chain interoperability. Concurrently, ZK technology is evolving from EVM-compatible zkEVMs to more efficient, ZK-optimized zkVMs. EIP-7825's parallelizable environment allows these zkVMs to operate at peak efficiency, drastically reducing proof generation cost and time. The convergence of EIP-7825, L1 zkEVM, and advanced zkVMs paves the way for the final stage of interoperability (Interop)—abstracting away chain boundaries to deliver a single-chain user experience where cross-chain actions are seamless, secure, and instantaneous.

Interop Roadmap "Acceleration": After Fusaka Upgrade, Ethereum Interoperability May Take a Key Leap

The Ethereum Fusaka upgrade, while primarily noted for expanding blob capacity and reducing L2 data costs, introduced the underappreciated EIP-7825—a critical enabler for Ethereum’s ZK and interoperability roadmap. EIP-7825 imposes a per-transaction gas limit (~16.78 million gas), preventing "mega-transactions" from blocking entire blocks. This change makes proof generation parallelizable, transforming it from a logic-bound challenge into a solvable computational problem. As a result, real-time ZK proofs become feasible, even for large blocks, paving the way for near-instant finality. This upgrade supports the development of L1 zkEVM, which can serve as a trust anchor for L2s, enabling secure, instant cross-chain communication without relying on optimistic challenge periods or centralized bridges. Furthermore, the shift from zkEVM to more efficient zkVM architectures is accelerated by EIP-7825, as zkVMs can leverage parallelization for faster, cheaper proof generation. Ultimately, these advancements are key to achieving seamless interoperability—not just for asset transfers, but for generalized cross-chain logic and communication—bringing Ethereum closer to a future where users experience a unified, chain-agnostic interface powered by real-time ZK verification.

New DePIN protocol rolls out ZK-Proof processing marketplace

Brevis has launched ProverNet, a decentralized physical infrastructure (DePIN) marketplace for zero-knowledge proof (ZK-proof) computation. The platform enables users to earn by providing proving capacity and allows applications to access scalable ZK-proof processing. Initially using USDC for settlements, the network plans to transition to its native BREV token upon mainnet launch, which will also introduce staking and slashing mechanisms for provers. ProverNet addresses the computationally intensive nature of ZK-proof generation by distributing tasks through continuous auctions and job matching. Brevis, already an established player, has processed over 250 million proofs for partners like Uniswap, PancakeSwap, and MetaMask. The system is designed to handle variable workloads, offering flexibility and avoiding vendor lock-in. Production workloads, including Ethereum block execution proofs from ETHProofs, are already being migrated to the new network.
