ChainCatcher report: Coinbase Developer Platform posted on X that the x402 protocol has rolled out several key updates: it now supports all ERC-20 tokens, enabling developers to accept on-chain payments for any ERC-20 token—including USDC, EURC, and even meme coins—via EIP-3009 and Permit2; a new “Sign-in-with-X” feature allows buyers to log in with their wallets to access purchased content, enabling sellers to offer payment-free access to returning customers, with support for both EVM and Solana wallets; and the launch of the x402 MCP software package, which allows developers to monetize any MCP tool and integrate it directly into AI workflows. These updates aim to make x402 the most flexible and open internet-native standard.
