Block Integrates Bitcoin Lightning Network Into x402 Payment Standard

The significance here is less the Lightning integration itself than the venue: Block is pushing an open HTTP-level payment handshake through its own stack, which could give machine-to-machine micropayments a distribution path that purely crypto-native standards have lacked. The absence of any timeline for Cash App, Square or Bitkey is the tell — until a consumer surface commits, this remains an R&D signal rather than a product one. The open question is whether the Python implementation clears real-node testing and whether merchants, not just Block's own properties, adopt the 402 pattern.
