Pieverse, the Web3 payment infrastructure platform, has demonstrated that it will significantly expand its x402b payment protocol on the Arbitrum network. This strategic deposit transition will make Ethereum’s transactions, which are audit-ready and gas-free, the largest Layer-2 scaling platform. It builds on Pieverse’s recent $10 million funding round and a successful launch on BNB Chain.
Bridging business needs with layer 2 efficiency
Pieverse first unveiled its protocol on the BNB chain in October 2025, but it gets a bridged inefficiency on Arbitrum that gives it access to a larger ecosystem. Arbitrum has currently processed over six million transactions daily and captured a total value of almost $19 billion, making it the most functional Layer-2 for Ethereum.
What sets this development apart is the way it integrates compliance-first infrastructure with Layer-2 performance benefits. Arbitrum’s new rollup design can process up to 40,000 transactions per second and can reduce gas costs by as much as 95% of the Ethereum mainnet. This translates to paying cents per transaction instead of using dollars in cases where companies use x402b to implement payment systems.
The x402b protocol is an extension of Coinbase’s x402 API on blockchains. The protocol can now connect to an ecosystem consisting of major DeFi protocols with the launch of Arbitrum, allowing the protocol to seamlessly integrate payment functionality across numerous decentralized applications.
Compliance and gasless payment challenge
x402b will solve two fundamental challenges for traditional blockchain payment systems. First, there are the gas fees, which refer to the computing costs the user must pay to make a transaction. These costs are prohibitive for the automated systems and AI agents that regularly execute small-value transactions.
Pieverse’s solution leverages EIP-3009 support by denominating payment in pieUSD, a wrapped stablecoin, to enable payment authorization via simple message signatures instead of blockchain transactions. This gasless payment system allows customers to complete transfers without holding native tokens for transaction fees, reducing the user experience.
The second challenge concerns audit and tax requirements, which are virtually absent from most blockchain payment protocols. The x402b architecture features a Facilitator module that automatically generates jurisdiction-compliant receipts during payment settlement. These receipts are securely stored on decentralized storage networks, creating a permanent audit trail that meets regulatory requirements in the US, EU and APAC regions. An industry survey shows that 74% of financial institutions say regulatory uncertainty is the biggest barrier to blockchain adoption.
Strategic implications for Web3 payments
The expansion leads to an increase in the number of business blockchain payments. Just as other Web3 infrastructure partnerships are reshaping payment systems, Pieverse’s multi-chain approach shows that payment protocols must be used across multiple blockchain ecosystems for meaningful adoption.
This contrasts with broader industry trends. Several payment processors are steadily adding blockchain features as they understand that Web3 payments require an infrastructure that bridges traditional financial and decentralized methods in one. Arbitrum’s scalability and x402b compliance allow businesses to use blockchain payment methods while remaining compliant with regulations.
The timing of AI agents and autonomous systems is particularly important due to the rapid advancement of technology. As these systems become more capable of managing different transactions independently, we need an infrastructure that can handle high volumes and maintain auditability. Pieverse has positioned x402b as the solution to ensure machine-executed transactions remain stable and auditable.
Conclusion
The integration clearly shows that blockchain payments are moving from mere token exchanges to a full-fledged financial infrastructure that will support business use cases. Pieverse has indicated plans for further multi-chain expansion, with Ethereum mainnet and Solana on the roadmap. Infrastructure projects like Pieverse will lay the foundation for the mainstream adoption of blockchain payments by solving fundamental problems related to cost, speed and compliance.
