Getting USDT onto Arbitrum
USDT is widely supported across Arbitrum's DeFi, but gas is paid in ETH, not USDT — so if you bridge only USDT you'll want a little ETH too, or a route that delivers gas on arrival. Confirm the destination token in the quote so you're holding the version your target app expects.
Arbitrum keeps Ethereum's settlement security underneath while dropping the cost of a typical transaction to usually a few cents. It carries the largest DeFi ecosystem of any L2, so most strategies you'd run on mainnet have real depth here. For active traders, that combination — mainnet-grade liquidity at L2 prices — is the main draw.
Stay safe while bridging
- Approve only what you’re bridging. The widget requests finite token approvals by default — there’s no need to grant an unlimited allowance.
- Check the URL every time. Bookmark this site and confirm the address bar before connecting a wallet.
- Start small for a new route. A tiny test transfer confirms everything works before you move the full amount.
Moving a large amount? Consider a hardware wallet
A hardware wallet keeps your private keys offline, so a compromised browser or a malicious approval can’t drain your funds on its own. It’s the single biggest security upgrade for anyone holding meaningful value on-chain.
