Notes and record state

Record note
DefiLlama identifies DPEX as a Polygon decentralized perpetual exchange with up to 50x leverage and reports residual current TVL plus substantial cumulative trading volume. Recent trading-volume windows were not exposed in the reviewed snapshot and no terminal shutdown evidence was recovered, so HEI uses limited rather than active or dead.
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
