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 zkSync Era.
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 zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. Bitcoin confirmations and zkSync Era transaction finality are separate milestones.
Route-specific mistakes include sending on a network other than zkSync Era; 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; confusing native BTC with wrapped or tokenized Bitcoin. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. 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.
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.
Chainlink is classified as a governance or utility token for this route. LINK uses a network-specific contract asset on zkSync Era. The zkSync Era side is contract-tracked rather than a native gas balance. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract.
zkSync Era wallet, token-transfer, contract, log, and gas activity remain public, and Bitcoin UTXO inputs, outputs, change, and confirmation history remain public. For this LINK on zkSync Era 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 zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum.
LINK is a contract representation on zkSync Era at 0x52869bae3e091e36b0915941577f2d47d8d8b534. ETH, not LINK, pays gas unless both symbols are the same. A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract.
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.
LINK is a contract-token input, so the source wallet needs the network’s native gas asset and may need to approve the exact LINK contract. 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.
LINK 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 LINK zkSync 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.
