As the machine economy accelerates, a new report from Keyrock reveals a developed ecosystem based on crypto for settling AI agent transactions. According to reports, stablecoins have become the default settlement layer for autonomous AI agents due to their efficiency in handling sub-dollar transactions. This shift occurs because traditional payment systems, such as credit cards, struggle with the high frequency and low value of micropayments required by autonomous AI agents, whereas blockchain rails handle them seamlessly.
This trend aligns with the broader expansion of digital assets, as the market capitalization of USDC surpassed $34 billion in May 2026 per market data, reinforcing its role in decentralized finance. Compared to the previous quarter, Circle's reports indicate a settlement volume increase of over 15% on-chain, largely driven by AI applications adopting pay-per-query models.
