What the data says about USDT
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.
The measured caveat is coverage: contract-level controls were not assessed in this snapshot, so the wrapper's levers are unverified rather than cleared — though on a bridged stablecoin the binding trust question has always been the issuer's, not the code's. Clone "USDT" contracts are the common impostor on every chain: verify the address, not the ticker.

Is USDT a safe token?
As of the 2026-09-27 snapshot, USDT scores 55/100 (grade C) on NexFlow's on-chain read — based on a contract that can mint new supply, cannot freeze or blacklist transfers, liquidity of $3.94M and 828,179 holders. That grades contract and market structure, not price direction — a clean read is not a guarantee, so re-scan before trading, since on-chain state can change.
Can you sell USDT, or is it a honeypot?
The 2026-09-27 contract read found no sell-blocking controls on USDT — no honeypot flag, no transfer pause, no blacklist — and every honeypot GoPlus positively flags is dropped from this index outright. That clears the contract side; how cleanly an exit fills still depends on your size against the $3.94M of measured depth.
Who holds most of USDT?
USDT has 828,179 holders as of 2026-09-27. A headline count doesn't reveal how much the largest wallets control, so read it with the concentration figure on this page — broad distribution is a good sign, a few wallets owning most of the supply is not.
Can USDT's supply be inflated?
Yes — the contract can still mint new supply as of the 2026-09-27 snapshot, so the deployer or a minter role can dilute holders. Treat the circulating figure as a floor, not a cap.
What is the USDT contract address?
The USDT contract address on Optimism is 0x94b008aa00579c1307b0ef2c499ad98a8ce58e58. Always verify a token by its contract address, not its name or ticker — scam clones copy tickers, but the address is unique.
Where can you buy USDT safely?
Run the live on-chain scan at the top of this page first; if USDT clears, you can swap it here directly. Whatever venue you use, match the contract address (0x94b008aa00579c1307b0ef2c499ad98a8ce58e58) exactly before trading — copying the ticker is how clone scams catch buyers, and the address is the one field they can't fake.
