Base uses EVM account addresses and ETH for source gas. Solana uses Solana accounts, transaction signatures, and SOL for destination activity. A 0x address is not a valid substitute for the Solana receiving address shown by the route. ETH uses native ETH on the source; WETH uses WETH wrapped token on Solana.
Base58-encoded Solana account address A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas. A compatible wallet may create or use an associated token account, and SOL—not WETH unless it is SOL—pays later Solana fees.
ETH is the native gas asset for Base. ETH is a native source balance. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger.
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 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 Base; using a destination that is not valid for Solana; running out of ETH before the source transaction is submitted; assuming evm and solana addresses are interchangeable; treating a wrapped token as the native gas asset. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. 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 classified as a native asset for this route. ETH uses a native asset on Base. The recorded Base representation uses 18 decimal places. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Solana. The recorded Solana representation uses 9 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 wallet, token-transfer, contract, log, and gas activity remain public, and Solana account, token, program, signature, and fee activity remain public. For this ETH on Base to WETH on Solana path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Base58-encoded Solana account address; it does not hide either chain's public records.
No. The destination must be a Solana-compatible address. Base58-encoded Solana account address
An SPL-token receipt uses the relevant mint and token account; the wallet or route may create an associated token account when needed. SOL is used for later Solana activity.
ETH is listed as the native representation on Base; ETH is used for network gas. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ.
WETH is a contract representation on Solana with 9 decimals at AaAEw2VCw1XzgvKB8Rj2DyK2ZVau9fbt2bE8hZFWsMyE. SOL, not WETH, pays gas unless both symbols are the same. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Native ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. 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.
ETH 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 ETH can fund both transfer value and gas on its selected network. If the source is WETH or another tokenized form, approval and unwrap or exchange logic differ. A Base source transaction is sequenced on the OP Stack rollup and later settles to Ethereum; Base ETH and Base token approvals remain on the L2 ledger. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. WETH arrives as a token contract balance. It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Requirements are checked for the live ETH Base to WETH Solana 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.
