Based on MarsBit, the recently concluded Devconnect ARG 2025 featured Trustless Agent Day as a key highlight, where Ethereum Foundation, Coinbase, and MetaMask jointly launched the ERC-8004 and x402 protocols. These standards aim to provide AI agents with on-chain identities and payment capabilities, marking a shift from API-based wrappers to a self-sovereign, interoperable agentic economy. The event emphasized infrastructure maturity and the need for product-market fit, with x402 enabling micro-payments via stablecoins and ERC-8004 offering identity and reputation systems. Developers urged a shift from building tools to deploying real-world applications, with gaming and DeFi automation identified as key entry points. However, concerns were raised about current agents being mere 'LARPing' scripts without true decision-making capabilities.
