Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Optimism. The recorded Optimism representation uses 6 decimal places. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The source is a stablecoin contract or recorded native representation, while LINK is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on Optimism. The Optimism side is contract-tracked rather than a native gas balance. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Optimism is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Optimism. EVM 0x account address 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.
Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for Optimism; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. 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. 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
Optimism wallet, token-transfer, contract, log, and gas activity remain public. For this USDT on Optimism to LINK on Optimism path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
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.
LINK is a contract representation on Optimism at 0x350a791bfc2c21f9ed5d10980dad2e2638ffa7f6. ETH, not LINK, 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
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, LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
USDT is the deposited stablecoin input; LINK is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
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. 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. LINK arrives as a network-specific contract balance. The wallet still needs the destination native asset before it can transfer or approve LINK later.
USDT must match its Optimism representation. A ticker or target price is not enough to identify a token contract.
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.
Requirements are checked for the live USDT OP Mainnet to LINK 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.
