Converting stablecoin USDT into WETH
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 WETH is classified as token. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
WETH output identity and receiving
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Arbitrum. The recorded Arbitrum representation uses 18 decimal places. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Linea source execution
Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Linea. EVM 0x account address A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones.
Linea to Arbitrum L2 handoff
This route crosses two L2 execution environments. Linea settles to ethereum, while Arbitrum settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
USDT input identity and handling
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Linea. The recorded Linea 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 destination execution
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.
WETH wrapped-token output 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 destination token on Arbitrum. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to USDT Linea to WETH Arbitrum
Route-specific mistakes include sending on a network other than Linea; 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; treating a wrapped token as the native gas asset. A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
