What exactly leaves Optimism as USDT?
USDT is a contract representation on Optimism with 6 decimals at 0x94b008aA00579c1307B0EF2c499aD98a8ce58e58. ETH, not USDT, pays gas unless both symbols are the same. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. 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 Linea as BNB?
BNB is a contract representation on Linea with 18 decimals at 0xf5C6825015280CdfD0b56903F9F8B5A2233476F5. ETH, not BNB, pays gas unless both symbols are the same. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
Why does the USDT to BNB 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, Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
What changes between the source and destination asset roles?
USDT is the deposited stablecoin input; BNB is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
What should be matched before sending USDT?
The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. Native BSC receipt can fund BNB gas, while externally bridged BNB arrives as a representation that needs the destination chain’s gas token.
Which stablecoin contract must this route match?
USDT must match its Optimism representation. A ticker or target price is not enough to identify a token contract.
What funds the Optimism source transaction?
ETH is the native gas asset for Optimism. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. USDT is token-tracked and can need approval before transfer.
Can I swap USDT on OP Mainnet to BNB on Linea without KYC?
Requirements are checked for the live USDT OP Mainnet to BNB Linea 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.
