The stack is coalescing around four layers: **payments, wallets, identity/trust, and validation**.\n- x402 is becoming the default payment rail for agents.** It’s an HTTP-native protocol for automatic stablecoin payments, so an agent can pay per request instead of needing accounts or subscriptions. Coinbase’s docs say it supports machine-to-machine payments, multiple networks, and a hosted facilitator for Base, Polygon, Arbitrum, World, and Solana. [^1]\n- Payments MCP is the agent-facing wrapper for that rail.** Coinbase launched it to give LLMs wallets, onramps, and stablecoin payments through natural language, and it’s been tested with Claude Desktop, Claude Code, Codex, Gemini, and Cherry Studio. That matters because it removes a lot of custom plumbing. [^2]\n- ERC-8004 is the trust layer taking shape on Ethereum.** It defines on-chain identity, reputation, and validation registries so agents can be discovered, scored, and verified without pre-existing trust. It explicitly treats payments as orthogonal, but compatible with x402-style proof-of-payment signals. [^3]\n- The Open Wallet Standard is filling the wallet gap.** MoonPay’s March 2026 launch standardizes how agents hold value and sign transactions without exposing private keys, which is the missing piece if multiple frameworks are going to interoperate cleanly. [^4]\n\n## Analysis\n- **The market is moving from “agent can act” to “agent can transact safely.”** That means spend limits, policy engines, on-chain identity, reputation filtering, and validation are becoming core product requirements, not extras. [^3][^4]\n\n**Bottom line:** the current wave is not just “AI agents on chain.” It’s the emergence of a **full commerce stack for agents**: **x402 for paying, OWS for signing, ERC-8004 for trust, and MCP-style tooling to wire it into models**.
