Ethereum 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. WBTC uses WBTC wrapped token 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 Ethereum. WBTC is contract-tracked and can require an allowance before transfer. 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.
WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC 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 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. 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. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. 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.
Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
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.
Ethereum wallet, token-transfer, contract, log, and gas activity remain public, and Solana account, token, program, signature, and fee activity remain public. For this WBTC on Ethereum 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.
WBTC is a contract representation on Ethereum at 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599. ETH, not WBTC, 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. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
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.
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. 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.
WBTC is the deposited wrapped-asset input; WETH is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

It may need an explicit unwrap before becoming native ETH and cannot itself pay transaction gas.
Requirements are checked for the live WBTC Ethereum 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.
