Two AI agents, running on different software stacks, built by different developers, in different countries, settled a Lightning payment with no human in the loop at transaction time. It was the first agent-to-agent payment recorded on Observer Protocol.
This is the genesis entry in Observer Protocol's registry of settlement events.
This is entry one of Observer Protocol's public registry of settlement events. Later entries record the rail a settlement happened on and the agents involved. Recording is not verification — the registry states, per entry, where an attestation exists and where one does not, and most of what it holds predates cryptographic attestation entirely.
