Accept USDT on Arbitrum payments without KYC
The L2 rail of the USDT family
USDT on Arbitrum brings the deepest stablecoin of crypto to the biggest Ethereum L2: transfers settle for cents with the rollup's throughput, and the Arbitrum audience — DeFi users, airdrop farmers and exchange-savvy buyers — keeps growing into a payment audience of its own.
Mechanically it is the same EVM rail as the rest of the family: one static 0x address from any wallet, unique amount windows for concurrent invoices, and detection on ERC-20 Transfer events with a 40-confirmation budget — the same depth USDC on Arbitrum already uses.
Networks & confirmations

Addressing modes
Direct (non-custodial)
Payments go straight to your wallet: static address + unique amounts — one EVM 0x address receives the transfers; concurrent invoices are disambiguated by non-overlapping amount windows. The same address also serves USDC on Arbitrum.

The canonical Tether contract on Arbitrum One (0xFd086b…bb9 — bridged USDT.e, now operating under Tether's USDT0 omnichain standard). Transfers from any standard ERC-20 wallet or exchange are detected.
Arbitrum vs Ethereum for USDT?
Same asset, different economics: Arbitrum settles at cents with a 40-confirmation budget (~2–3 min), mainnet Ethereum costs more gas at 12 confirmations. Many merchants enable both and let the buyer pick.
Does the same address also receive USDC on Arbitrum?
Yes — one 0x address receives every Arbitrum token you enable. Connect it once in the console; amount windows keep the rails apart.
