What the data says about Tether USD
USDT on Optimism at 0x94b008aa00579c1307b0ef2c499ad98a8ce58e58 is the canonical bridged Tether on this chain — the contract the standard bridge issues when mainnet USDT is locked on Ethereum. Two things follow: the asset's backing lives on another chain inside Tether's own mint-and-freeze powers, and "USDT" on Optimism under any other address is something else entirely.
The market has had 1,513 days to mature: $3.9 million of tracked liquidity against a $261.4 million cap — workable depth for ordinary size — on roughly $3.5 million of daily volume at the September 27, 2026 snapshot.
Other Tether USD conversions
How this conversion works
The token side is NexFlow's own measured read — the newest of our intraday, daily-snapshot or corpus figures, taken 2026-09-27. The currency side is the ECB daily reference rate, 1 USD = 1355.05 KRW, dated 2026-09-25. Both inputs are dated because both drift; the figure above is the product of the two, not a venue quote.
