What you need to know

Move from a Solana account into Linea EVM

Solana uses Solana accounts and SOL for source fees, while Linea uses an EVM 0x account and ETH for destination gas. Confirm the destination token contract and do not paste a Solana address into the EVM destination field. WETH is read from its Solana mint or native account, while USDT arrives at the quoted Linea native or contract representation.

WETH mint and SOL fee checks

Base58-encoded Solana account address SOL is the native gas asset for Solana. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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. The mint/account selected by the quote must match the source wallet balance.

Linea contract and 0x receiving checks

EVM 0x account address ETH is the native gas asset for Linea. 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another. A Solana address cannot receive this EVM-side output.

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 Linea representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.

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

Route-specific mistakes include sending on a network other than Solana; using a destination that is not valid for Linea; running out of SOL before the source transaction is submitted; assuming solana and evm addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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. 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

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.

USDT output identity and receiving

Private Route for WETH → USDT

Solana account, token, program, signature, and fee activity remain public, and Linea wallet, token-transfer, contract, log, and gas activity remain public. For this WETH on Solana to USDT on Linea path, Private Route is intended to reduce the direct visible relationship between activity around the source-side Base58-encoded Solana account address and destination-side EVM 0x account address; it does not hide either chain's public records.
