Lightning Labs has launched Wavelength, a new tool designed to simplify Bitcoin transactions for developers and autonomous agents. Available on Signet and testnet, with mainnet access by invitation, Wavelength offers a streamlined API through the Model Context Protocol. This allows machines to conduct microtransactions, such as paying fractions of a cent, while ensuring users maintain full control over their keys. This development marks a significant step in facilitating machine-to-machine payments, enhancing the utility of Bitcoin in automated environments.
