It spends discrete UTXOs rather than debiting an account balance. Input selection creates outputs and often change, confirmation depth matters to the provider, and a native receiving address must match the Bitcoin address types accepted by the active route. The receiving address must be a Bitcoin address accepted by the active provider. The delivered BTC becomes a UTXO; it is not a token contract or gas balance on Solana.
Native BTC is a Bitcoin UTXO asset with confirmations and Bitcoin address rules. Tokenized or wrapped Bitcoin on a smart-contract chain follows a contract ledger instead of the native UTXO graph. The live route must identify native BTC explicitly; a BTC ticker on another chain can represent a wrapped or bridged token.
The provider sets the required Bitcoin confirmation depth. Base58-encoded Solana account address A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. Bitcoin confirmations and Solana transaction finality are separate milestones.
Route-specific mistakes include sending on a network other than Solana; using a destination that is not valid for Bitcoin; running out of SOL before the source transaction is submitted; assuming solana and bitcoin addresses are interchangeable; confusing native BTC with wrapped or tokenized Bitcoin; 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 Bitcoin destination creates a UTXO at a supported Bitcoin address; later spending pays a BTC miner fee and begins new confirmation progress. Native BTC must arrive at a provider-accepted Bitcoin address and becomes a UTXO after broadcast; an EVM address is not a native BTC destination.
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.
Bitcoin is classified as a UTXO-native asset for this route. BTC uses a native asset on Bitcoin. Native BTC exists on one recorded origin network; other network forms require representation checks. Native BTC must arrive at a provider-accepted Bitcoin address and becomes a UTXO after broadcast; an EVM address is not a native BTC destination.
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 leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
Solana account, token, program, signature, and fee activity remain public, and Bitcoin UTXO inputs, outputs, change, and confirmation history remain public. For this WETH on Solana to BTC on Bitcoin 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 Native Bitcoin address supported by the route, including network-specific bech32 or legacy formats; it does not hide either chain's public records.
The Bitcoin side uses native BTC and the UTXO ledger. Native BTC is a Bitcoin UTXO asset with confirmations and Bitcoin address rules. Tokenized or wrapped Bitcoin on a smart-contract chain follows a contract ledger instead of the native UTXO graph.
Destination Bitcoin receipt has its own confirmation progress. The account-chain transaction and the Bitcoin transaction are separate records.
A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees.
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 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.
BTC is listed as the native representation on Bitcoin; BTC is used for network gas. A Bitcoin destination creates a UTXO at a supported Bitcoin address; later spending pays a BTC miner fee and begins new confirmation progress. Native BTC must arrive at a provider-accepted Bitcoin address and becomes a UTXO after broadcast; an EVM address is not a native BTC destination.
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. On receipt, Native BTC must arrive at a provider-accepted Bitcoin address and becomes a UTXO after broadcast; an EVM address is not a native BTC destination.
WETH is the deposited token input; BTC is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
Requirements are checked for the live WETH Solana to BTC Bitcoin 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.
