At Korea Blockchain Week 2026, experts argued that current blockchain infrastructure is insufficient to support the emerging economy of autonomous AI agents.
Cardano has integrated the x402 payment standard, enabling AI agents to settle transactions in ADA, which triggered a 4% price increase to a four-month high.
Cardano has integrated with the x402 SDK, allowing AI agents and applications to pay for API services directly on-chain via HTTP requests without traditional accounts.
Ripple has released a developer toolkit that allows AI agents to autonomously conduct payments on the XRP Ledger using the x402 protocol.
TRM Labs research indicates that AI agents represent only a small fraction of transactions on the x402 protocol, which is dominated by conventional scripts and USDC stablecoin payments.
Solana now accounts for 70% of the x402 micropayment protocol volume, processing $24.24 million in transactions over the last month.
New research from TRM Labs suggests that AI agents currently account for a minimal share of commerce on the x402 protocol, despite growing industry investment in agent-based payment systems.
