Coinbase launches "Agentic Wallets" for AI agents; x402 logs 50M transactions

Coinbase said in a Wednesday blog post that it is rolling out "Agentic Wallets," infrastructure built to let autonomous AI agents hold funds, send payments, trade tokens, earn yield, and transact onchain. The tool initially supports EVM chains and Solana, offers gasless transactions on Base Layer 2, and adds security guardrails and a CLI for management.
