Notes and record state

Record note
The current first-party Metric domain remains reachable. Current multi-chain TVL and Swap-event volume are independently reflected by DefiLlama across nine networks. Because public first-party technical documentation is limited, confidence remains medium and no exact launch date, legal jurisdiction, or implementation lineage is asserted.
Revision state
Records may be incomplete, approximate, contested, or revised as better evidence becomes available.
This record may be incomplete or revised. Dead-side entries prefer archived URLs over original domains. Dates, causes, and classifications may change when stronger evidence becomes available. Contact / corrections
