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 Linea.
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. EVM 0x account address A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. Bitcoin confirmations and Linea transaction finality are separate milestones.
Route-specific mistakes include sending on a network other than Linea; using a destination that is not valid for Bitcoin; running out of ETH before the source transaction is submitted; assuming evm and bitcoin addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; confusing native BTC with wrapped or tokenized Bitcoin. A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. 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.
USDC is an issued dollar-oriented stablecoin with canonical, native, and bridged variants across networks. Contract events and issuer controls differ from a network-native gas asset. The source is a stablecoin contract or recorded native representation, while BTC is classified as native-asset. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
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.
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Linea. The recorded Linea representation uses 6 decimal places. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.
Linea wallet, token-transfer, contract, log, and gas activity remain public, and Bitcoin UTXO inputs, outputs, change, and confirmation history remain public. For this USDC on Linea to BTC on Bitcoin path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x 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 Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones.
USDC is a contract representation on Linea with 6 decimals at 0x176211869cA2b568f2A7D4EE941E073a821EE1ff. ETH, not USDC, pays gas unless both symbols are the same. A Linea source is executed on the zkEVM rollup and later proven to Ethereum; L2 inclusion and proof settlement are distinct source milestones. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.
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.
The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. 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.
USDC is the deposited stablecoin 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 USDC Linea 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.
