Market activity and issuer metadata answer different questions.
Price history uses pair-specific daily closing bars with the base side inferred by Codex. Reserves are the currently reported pooled token balances; rolling changes and volumes use filtered pair statistics. Daily diagnostics describe the latest UTC bar, which may still be in progress, and the swap ledger shows the 20 newest indexed Swap events for this contract. Market data refreshes on a 15-minute cache. The USDS issuer, backing model, and network availability remain source-backed on the token record.
