Pieverse has announced a collaboration with U to utilize the U stablecoin in supporting AI agent payments centered around the Universal Commercial Protocol (UCP). According to Foresight News, Pieverse has integrated x402b into the U ecosystem and incorporated UCP into its technology stack, enabling AI agents to handle processes from discovery to checkout and settlement via x402b. Additionally, ERC-8004 is set to launch on the BNB mainnet, allowing Pieverse agents to support cross-ecosystem reputation management. Autonomous agents can leverage U's unified liquidity for purchases or subscriptions, while merchants can settle transactions through on-chain proof.
