Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Ethereum. The recorded Ethereum representation uses 9 decimal places. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.
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 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 Base. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network 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.
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.
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.
Ethereum and Base can use the same 0x address syntax, but they are separate networks with different chain identifiers, gas balances, token contracts, and transaction histories. The recorded settlement context includes ethereum, so L1 and L2 confirmation behavior should not be assumed identical.
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. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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 SOL 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.
SOL is a contract representation on Ethereum with 9 decimals at 0xD31a59c85aE9D8edEFeC411D448f90841571b89c. ETH, not SOL, 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. Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead.
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.
Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. On receipt, WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
SOL is the deposited native-asset input; WETH is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
Native SOL leaves a Solana account through a signed transaction and pays the fee; wrapped or tokenized SOL uses a token account or external contract instead. 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. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
No. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. 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.
ETH is the native gas asset for Ethereum. 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. SOL is token-tracked and can need approval before transfer.
Requirements are checked for the live SOL Ethereum to WETH 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.
