Choose the WETH asset and Ethereum network you currently hold.
Check the estimated output, fees, timing, and Base destination network.
Open the live route and follow the exact deposit instructions.
Use the receipt and status page until the destination funds arrive.
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Ethereum. The recorded Ethereum 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.
Ethereum source execution occurs on L1, while Base delivery occurs on a separate L2 ledger that settles to ethereum. ETH pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Base. The recorded Base 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.
Base is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Base. EVM 0x account address A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.
Ethereum is a L1 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Ethereum. EVM 0x account address An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit.
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 Ethereum. 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 Ethereum; using a destination that is not valid for Base; running out of ETH before the source transaction is submitted; treating a wrapped token as the native gas asset. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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 Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Ethereum wallet, token-transfer, contract, log, and gas activity remain public, and Base wallet, token-transfer, contract, log, and gas activity remain public. For this WETH on Ethereum to WETH on Base 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.
WETH is a contract representation on Ethereum with 18 decimals at 0xb1A7F8b3AdA1Cbd7752c1306725b07D2F8B4e726. ETH, not WETH, pays gas unless both symbols are the same. An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. 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.
WETH is a contract representation on Base with 18 decimals at 0x4200000000000000000000000000000000000006. ETH, not WETH, pays gas unless both symbols are the same. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
No. This bridge keeps the asset intent while moving between a WETH wrapped token and a WETH wrapped token. Match the source and output details in the live quote.
An Ethereum source pays L1 base and priority fees in ETH, and an ERC-20 input can require a separate approval before the route deposit. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. The bridge output does not automatically fund every later gas need.
EVM 0x account address Do not substitute a Ethereum address merely because a wallet displays both networks.
Sending on a network other than Ethereum, selecting a representation not listed by the quote, or entering an address invalid for Base can prevent normal detection or receipt.
Requirements are checked for the live WETH Ethereum to Base 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.
