KakaoPay Demonstrates AI Agent Payment System Linked to Stablecoins

KakaoPay announced on the 15th that it has successfully concluded a proof of concept (PoC) for 'Agentic Payment' technology, which allows AI agents to perform payment processing during purchase and sale transactions.

The demonstration included not only purchasing payments by AI agents but also enabling sellers to sell web resources like data to AI agents and settle earnings. Agentic Payment operates by granting an AI agent a wallet with set purchase permissions and payment limits; the agent then autonomously decides on necessary goods, services, or data within predefined boundaries for payment execution, based on protocols such as x402. KakaoPay previously joined the x402 Foundation, launched by the Linux Foundation in April, as the first domestic payment service provider member.

In this PoC, KakaoPay implemented integration of its digital asset wallet and payment infrastructure with stablecoin payments. The company explained that it established all necessary procedures for Agentic Payment, including wallet linkage, payment processing, settlement, balance/limit/policy management, and agent-to-agent communication.

Users can now check AI agent payment history, limits, and usage locations through the KakaoPay app as usual. Additionally, KakaoPay validated a monetization feature for sellers: vendors holding APIs or web resources can sell data to external AI agents via stablecoin payments and settlements. For example, an enterprise with map rating data or weather information could sell it to AI agents needing such data.

KakaoPay also linked business wallets with business accounts so sellers can monitor sales and settlement details through a dedicated dashboard. The company described this as providing a single infrastructure encompassing wallet management, payment processing, blockchain-based settlements, and dashboards.

'We have laid the technical foundation for bidirectional Agentic Commerce, where agents trade without human intervention to benefit both buyers and sellers,' KakaoPay stated. 'We will continue building infrastructure that enables stablecoins and other digital assets to be utilized.'

Meanwhile, KakaoPay plans to strengthen user protection measures in line with domestic digital asset regulatory policies based on this PoC, while advancing the commercialization and adoption of Agentic Payment technology.
