What exactly leaves BNB Chain as USDT?
USDT is a contract representation on BNB Chain with 18 decimals at 0x55d398326f99059fF775485246999027B3197955. BNB, not USDT, pays gas unless both symbols are the same. A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
What exactly arrives on Optimism as WETH?
WETH is a contract representation on Optimism with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, pays gas unless both symbols are the same. An OP Mainnet receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Why does the USDT to WETH direction matter?
The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. On receipt, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
What changes between the source and destination asset roles?
USDT is the deposited stablecoin input; WETH is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending USDT?

Which stablecoin contract must this route match?
USDT must match its BNB Chain representation. A ticker or target price is not enough to identify a token contract.
Can the wrapped asset pay native network gas?

A BNB Smart Chain source uses BNB gas and BEP-20 contracts; a familiar 0x account does not turn a BEP-20 deposit into ERC-20.

Can I swap USDT on BSC to WETH on OP Mainnet without KYC?
Requirements are checked for the live USDT BSC to WETH OP Mainnet quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
