You can transfer USDT from your Sui wallet to Binance by first checking if Binance supports USDT deposits on the Sui network, since not all exchanges list every chain. Open Binance, go to Wallet → Deposit → USDT, and select the available networks. If Sui is listed, you can choose it, copy the deposit address, then in your Sui wallet select Send → USDT → paste Binance address → confirm transaction. If Binance does not support Sui directly, you’ll need to bridge your USDT from Sui to a supported chain like Ethereum, BNB Chain, or Solana using a cross-chain bridge, then deposit through that network. Always match the same network on both sides, otherwise funds can be lost. For gas, you’ll need a small amount of SUI tokens to cover transaction fees.
