The first KRW-denominated public blockchain operates with built-in regulatory compliance, native AI agent identity, and integration with Model Context Protocol (MCP), Claude Skills, Gemini CLI, and Cursor. The underlying technology already powers BDAN Pocket, a digital wallet used by 4 million citizens of Busan.
Hashed Open Finance, the fintech subsidiary of global venture capital firm Web3 Hashed, today launched the public testnet for Maroo, the first layer-1 sovereign blockchain designed for Korea’s KRW stablecoin economy.
Since the global stablecoin market is almost entirely denominated in US dollars, Maroo offers Korean banksand native infrastructure for fintech and AI agents to transact in won-denominated digital assets. The technology underpinning Maroo already powers BDAN Pocket, a digital wallet used by 4 million Busan citizens in partnership with the Busan Digital Assets Exchange (BDAN).
The Maroo testnet is now open to third-party developers, banks, fintech companies, and AI builders. This launch places Korea among the first countries to design a public blockchain around its own currency instead of the US dollar.
Maroo was designed from the beginning with regulatory compliance, auditability, and verifiable privacy as part of its core, allowing banks and fintech companies to launch real-world services on Maroo while maintaining the openness of the public chain. The chain operates on a dual-path model: an “open path” available to anyone, and a “regulated path” for transactions that require prior verification. Both paths share the same chain, allowing Maroo to test whether ordinary users and regulated financial services can coexist in a single infrastructure.
Instead of relying on post-hoc reviews, Maroo enforces compliance as a code at the moment a transaction is made. The Programmable Compliance Layer (PCL) currently covers five core policies: KYC verification, transfer limits, blacklist filtering, time-based volume caps, and AI agent transactions. Any non-compliant on-chain transaction is blocked immediately. Policy sets can be updated through a separate path, allowing the network to adapt to new rules and service policies without redesigning the underlying protocol.
To prepare for a future in which AI agents are actively involved in financial transactions, the test network is also offering the Maroo Agent Wallet Stack (MAWS). Based on the ERC-8004 standard, MAWS assigns a unique on-chain identity to each AI agent. Agents can execute transactions autonomously, but only within user-defined permissions and limits. MAWS integrates seamlessly with key AI developer tools, including Model Context Protocol (MCP), Claude Skills, Gemini CLI, and Cursor. To balance autonomy and user control, users can revoke permissions immediately if abnormal behavior is detected.
On the testnet, transaction fees are paid in OKRW, a test token denominated in KRW, allowing users to participate in the network without holding volatile cryptocurrencies. In addition to technical testing, Maroo offers demonstrations of practical scenarios that showcase real-world benefit, including KYC integration with Kakao, Korea’s leading messaging platform. Hashed Open Finance plans to introduce more advanced privacy features, including Shielded Pool, at its next milestone later this year, with the mainnet launch following stringent security audits.
“In this testnet, we translated the basic design from our January literature paper into a live network environment.” He said Hoojin Kim, CEO of Hashed Open Finance. “A framework in which AI agents maintain unique on-chain identities and execute financial transactions autonomously within user-defined rules will be a meaningful milestone for the future of blockchain-based finance.” “Stablecoins are not just another financial product – they are the infrastructure that will define what a country’s currency will look like in the digital age.” He said Simon Kim, CEO of Hashid. “Currently, this infrastructure is built almost entirely on top of the dollar. Maroo represents a rare opportunity for Korea to design its own digital financial system based on the won. Our goal is to make it an open platform where anyone – banks, financial institutions, fintech companies and the new types of players that will emerge in the era of artificial intelligence – can come in and experience the next generation of finance.”
Start building on Maroo today. The testnet is completely open to the public. Developers can access the full documentation and start building immediately at docs.maroo.io, with the RPC endpoint available at rpc-testnet.maroo.io and on-chain activity can be viewed through the block explorer at explorer-testnet.maroo.io. AI creators can publish AI agent portfolios through (agent.maroo.io). End users can experience compatible KRW transactions on the test portal (experience.maroo.io), with KYC available at (kyc-testnet.maroo.io). Banks, FinTechs and financial institutions interested in trialling Maroo production services or partnership opportunities are invited to contact Hashed Open Finance at (inquiry@hashedopenfinance.com).
