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 POL is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
POL (ex-MATIC) is classified as a governance or utility token for this route. POL uses a network-specific contract asset on Arbitrum. The recorded Arbitrum representation uses 18 decimal places. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
zkSync Era is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on zkSync Era. EVM 0x account address A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum.
This route crosses two L2 execution environments. zkSync Era settles to ethereum, while Arbitrum settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on zkSync Era. The recorded zkSync Era 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.
Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Arbitrum. EVM 0x account address An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately.
Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for Arbitrum; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
zkSync Era wallet, token-transfer, contract, log, and gas activity remain public, and Arbitrum wallet, token-transfer, contract, log, and gas activity remain public. For this USDT on zkSync Era to POL on Arbitrum 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 zkSync Era with 6 decimals at 0x493257fD37EDB34451f62EDf8D2a0C418852bA4C. ETH, not USDT, pays gas unless both symbols are the same. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.
POL is a contract representation on Arbitrum with 18 decimals at 0x044d8e7F3A17751D521efEa8CCf9282268fE08CC. ETH, not POL, pays gas unless both symbols are the same. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
USDT is the deposited stablecoin input; POL 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. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
USDT must match its zkSync Era representation. A ticker or target price is not enough to identify a token contract.
ETH is the native gas asset for zkSync Era. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. USDT is token-tracked and can need approval before transfer.
Requirements are checked for the live USDT zkSync to POL Arbitrum 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.
