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 Linea. The recorded Linea 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.

Scroll source execution

Scroll is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Scroll. EVM 0x account address A Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently.

Scroll to Linea L2 handoff

This route crosses two L2 execution environments. Scroll settles to ethereum, while Linea 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 Scroll. The recorded Scroll 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.

Linea destination execution

Linea is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Linea. EVM 0x account address A Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract.

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 Linea. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to USDT Scroll to WETH Linea

Route-specific mistakes include sending on a network other than Scroll; using a destination that is not valid for Linea; 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 Scroll source executes in the zkEVM and is later included in a proof batch to Ethereum; Scroll contract identity must be verified independently. 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 Linea receipt is recorded on the zkEVM L2 before the related proof settles to Ethereum; later activity needs ETH on Linea and the Linea token contract. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.

Private Route for USDT → WETH

Scroll wallet, token-transfer, contract, log, and gas activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this USDT on Scroll to WETH on Linea 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.
