Aptos, a Layer 1 blockchain, is building a suite of tools for machine-to-machine commerce targeting autonomous AI agents, relying on its x402 payment protocol and a partnership with io.net for on-demand rental of idle GPU capacities. Settlements occur in USDC with finalization under 50 milliseconds and fees below $0.0005. Since its launch in May 2025, the x402 ecosystem has processed over 100 million payments, with USDC accounting for more than 99% of all settlements. The stablecoin market cap on Aptos stands at approximately $1.9 billion, and the Aptos Foundation alongside Aptos Labs committed $50 million in May 2026 to fund AI agent tools and infrastructure development, including products Decibel and Shelby.
