What USDT representation leaves Ethereum?
USDT is a contract representation on Ethereum at 0xdac17f958d2ee523a2206206994597c13d831ec7. ETH, not USDT, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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 USDT representation arrives on Optimism?
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 receipt belongs to the OP Stack L2 and needs ETH on that network for later activity; it is not an Ethereum L1 balance. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
Does the same USDT ticker guarantee the same ledger form?
No. This bridge keeps the asset intent while moving between a USDT contract token and a USDT contract token. Match the source and output details in the live quote.
Which gas balances matter for this bridge?
An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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. The bridge output does not automatically fund every later gas need.
What destination address should be used?
EVM 0x account address Do not substitute a Ethereum address merely because a wallet displays both networks.
What wrong-direction mistake can prevent delivery?
Sending on a network other than Ethereum, selecting a representation not listed by the quote, or entering an address invalid for Optimism can prevent normal detection or receipt.
Can I bridge USDT from Ethereum to Optimism without KYC?
Requirements are checked for the live USDT Ethereum to Optimism 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.
