USDT on Arbitrum One trades through contract 0xFd086bC7CD5C481DCC9C85ebE478A1C0b69FCbb9, tagged USD₮0 on arbiscan.io. Since January 2025, Arbitrum's Tether-issued USDT has run on Tether's USDT0 omnichain standard rather than the older canonical-bridge deployment. A simple transfer costs about $0.004 to $0.05 in ETH gas at current network conditions, confirms in well under a second on the sequencer, and reaches hard finality on Ethereum L1 in about 7 days. For most users this is still the cheapest fast option on a major L2.
​

For a USDT transfer between non-custodial wallets, Arbitrum One sits in the cheap-and-fast bucket alongside Optimism and Base. Ethereum L1 is the slow expensive baseline. Polygon PoS is cheaper still in absolute terms but lacks Arbitrum's DeFi depth.

Sources: arbiscan.io gas tracker and token pages, arbitrum.foundation docs, DeFiLlama stablecoin dashboard, all checked September 21, 2026. Polygon's USDT was upgraded from bridged USDT to native USDT0 in 2025 as well, so both chains in this table now run the same OFT standard rather than separate bridged wrappers.
​

Neither in the old sense. Tether deployed native USDT directly on Arbitrum One in November 2022, then migrated the deployment to the USDT0 omnichain standard in January 2025. The current token, built on LayerZero's OFT framework, is still Tether-issued and backed 1:1, but transport between chains now runs through USDT0's own bridge rather than the original canonical Arbitrum bridge.
​

Arbitrum's governance has been unwinding the legacy path. A Constitutional AIP passed in 2025 disables the old canonical USDT bridge entirely, since "the majority of crosschain volume has migrated to the new USDT0 bridge" and the legacy path still carried a 7-day withdrawal delay and fund-loss risk for smart-contract depositors. You can verify the live contract and mint history on the token page at arbiscan.io.
​

This matters for two reasons. First, moving USDT to or from Arbitrum should go through the USDT0 bridge at usdt0.to, not the legacy Arbitrum Bridge, which is being phased out for this token specifically (it still works for ETH and other assets). Second, because USDT0 is a Tether-affiliated OFT rather than a third-party wrapper, it carries Tether's reserve risk plus LayerZero's messaging-layer trust assumption, not a separate bridge operator's risk.
​

Sending USDT on Arbitrum takes five steps once your wallet already holds a balance: connect to Arbitrum One, paste the recipient address, enter the amount, confirm the network fee, and sign. The whole flow typically completes in under a minute including sequencer confirmation.

If you are sending to a centralized exchange, always select "Arbitrum One" as the network in that exchange's deposit or withdrawal screen before generating the address. Selecting the wrong network is the single most common way users lose funds on this route.
​

A simple USDT transfer currently costs about $0.004 to $0.05 in ETH gas, per Arbiscan's gas tracker checked September 21, 2026, which showed base gas at 0.02 gwei and a standard ERC-20 transfer priced under a cent. Cost varies with two inputs: Arbitrum gas price, set by the sequencer based on demand, and Ethereum L1 calldata price, since Arbitrum posts compressed batches to L1 and passes that cost through. When L1 gas spikes, Arbitrum fees can climb toward $0.50.
​

EIP-4844 blob transactions, live since March 2024, moved rollup data into a separate blob fee market rather than ordinary L1 calldata, which is the main reason Arbitrum transfer fees stay low even when L1 is busy. Check the live readout at arbiscan.io/gastracker before sending a large batch of transactions.
​

Two timeframes matter. Soft confirmation from the Arbitrum sequencer takes about 250 milliseconds, per Arbitrum's own documentation, and is what wallets show as "confirmed." This is sufficient for exchange deposits and most peer-to-peer transfers.
​

Hard finality, meaning the transaction is settled on Ethereum L1 and cannot be reversed by a sequencer failure, takes about 7 days due to the optimistic-rollup challenge window. Centralized exchanges generally credit Arbitrum deposits after 1 to 20 L1 confirmations of the batch posting, which is 5 to 30 minutes, not the full 7 days. Coinbase credits after 1 batch confirmation; Binance after 20.
​

Every major EVM wallet supports Arbitrum One out of the box or after a one-click network add:

​

Four routes, ranked by cost and speed for a typical $1,000 to $50,000 transfer. The legacy Arbitrum canonical bridge is no longer the recommended path for USDT specifically, since Arbitrum governance voted to disable it for this token in favor of the USDT0 bridge.
​

Bridge at usdt0.to, the canonical front-end for the OFT standard Arbitrum's USDT now runs on. Funds typically arrive in a few minutes via LayerZero messaging. Fee is LayerZero messaging plus L1 gas, generally a few dollars on a mid-size transfer. This has replaced the old canonical bridge as the primary USDT route into Arbitrum per the Arbitrum governance proposal that phased out the legacy path.
​

stargate.finance also routes USDT via LayerZero messaging. Arrival in 1 to 3 minutes. Fee is L1 gas plus a small protocol fee, generally single-digit dollars on a $10K transfer. Used for time-sensitive moves.
​

across.to is an optimistic-bridge model with relayer fronting. Typically arrives in 30 seconds to 2 minutes. Fees vary by route and are typically a small fraction of the transfer amount; check the live quote before confirming. Best for sub-$25K transfers where speed matters.
​

CEX route as a fourth option: withdraw USDT directly from Binance, Coinbase, OKX, or Kraken on the Arbitrum network. Free or $1 to $2 fee. Slower because of exchange withdrawal queues but no bridge to operate directly.
​

No. Circle's Cross-Chain Transfer Protocol (CCTP) is USDC-only. It uses Circle's burn-and-mint authority over USDC. Tether's equivalent for USDT is the USDT0 OFT standard covered above, a different architecture that wraps mainnet USDT in a lockbox rather than burning and minting native supply per chain. Cross-chain USDT moves always go through USDT0, another third-party bridge (Stargate, Across, Wormhole), or an exchange.
​

If you need native-mint cross-chain stablecoin moves between L2s, USDC via CCTP is the only path with that exact mechanism today. See the Eco guide on CCTP at /support/en/articles/14998923, and the guide to USDT0 itself at /support/en/articles/14998914.
​

Both are liquid on Arbitrum, but USDC is now meaningfully larger. USDC supply on Arbitrum was about $2.26 billion versus USDT's roughly $828 million, per the DeFiLlama stablecoin dashboard checked September 21, 2026, making USDC the dominant stablecoin on this chain at roughly 62% of Arbitrum's $3.66 billion total stablecoin market cap.

For DeFi (GMX, Camelot, Aave Arbitrum) both are accepted across major pools.
​

Arbitrum One uses a single centralized sequencer operated by Offchain Labs. If it goes offline, new transactions stop confirming until either the sequencer recovers or users force-include transactions via L1, a process that takes about 24 hours.
​

Outages do happen. In the December 15, 2023 incident the sequencer stalled at 10:29 AM ET and resumed at 11:57 AM ET, with elevated gas until 4:04 PM. Existing balances are never at risk during sequencer outages because the state is anchored to Ethereum L1. The only impact is that pending sends cannot land until the sequencer resumes. Plan around this if you operate payroll, settlement, or arbitrage flows on Arbitrum USDT: keep a small buffer of L1 USDT for force-include fallback.
​

The USDT0 token on Arbitrum recorded about 182,000 transfers in the 24 hours checked on arbiscan.io on September 21, 2026, out of more than 316 million lifetime transfers on that contract. Daily onchain gas spend attributed to the USDT0 contract ranked among the top 15 gas-consuming contracts on the chain that day, per the same source.
​

For payment use cases (B2B settlement, payroll, remittance), Arbitrum's sub-cent fee profile makes small-value USDT payments economically viable in a way Ethereum L1 generally is not.
