WETH input identity and handling
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on zkSync Era. The recorded zkSync Era representation uses 18 decimal places. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
Receiving stablecoin USDT
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 destination wallet must support the exact Ethereum representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.
Leaving zkSync Era L2 for Ethereum L1
zkSync Era inclusion and its ethereum settlement are distinct from final receipt on Ethereum. The live route, rather than a generic rollup withdrawal assumption, determines the provider path and timing for this direction.
USDT output identity and receiving
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
Ethereum destination execution
Ethereum is a L1 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Ethereum. EVM 0x account address An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.
zkSync Era source execution
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.
WETH unwrap or exchange input check
WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH is the source token on zkSync Era. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to WETH zkSync Era to USDT Ethereum
Route-specific mistakes include sending on a network other than zkSync Era; using a destination that is not valid for Ethereum; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
