Accept USDT on Arbitrum.

USDT on Arbitrum offers a balance of low fees and high security, backed by Ethereum's validator network.

Arbitrum One is the largest Ethereum Layer 2 by total value locked, which makes it a natural home for USDT. It runs as an optimistic rollup on the Nitro stack: transactions execute on Arbitrum and settle back to Ethereum, inheriting Ethereum's security through fraud proofs while gas stays around $0.10 and confirmations land near 2 seconds. Tether issues USDT natively on Arbitrum, so there is no wrapped-token or bridging risk to manage. The practical advantage for a merchant is liquidity: Arbitrum hosts the deepest DeFi activity of any rollup, so a large share of active USDT holders already keep funds there and can pay without first moving them across a bridge. The fee sits slightly above ultra-cheap chains like Polygon or BNB, but it buys Ethereum-grade settlement guarantees, which is the right trade for larger payments. With enforced payments, you decide which chain a customer pays on, so you can route smaller transactions to cheaper chains and reserve Arbitrum for customers who already hold USDT there.
