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 deposit is a Bitcoin transaction funded by selected inputs; BTC network fees and change outputs are part of the source record before ARB can be delivered on Ethereum.
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 An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. Bitcoin confirmations and Ethereum transaction finality are separate milestones.
Route-specific mistakes include sending on a network other than Bitcoin; using a destination that is not valid for Ethereum; running out of BTC before the source transaction is submitted; assuming bitcoin and evm addresses are interchangeable; confusing native BTC with wrapped or tokenized Bitcoin. A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth. A native BTC deposit spends selected UTXOs, pays a BTC miner fee, can create change, and advances through Bitcoin confirmations. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
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. A native BTC deposit spends selected UTXOs, pays a BTC miner fee, can create change, and advances through Bitcoin confirmations.
Bitcoin UTXO inputs, outputs, change, and confirmation history remain public, and Ethereum wallet, token-transfer, contract, log, and gas activity remain public. For this BTC on Bitcoin to ARB on Ethereum path, Private Route is intended to reduce the direct visible relationship between activity around the source-side Native Bitcoin address supported by the route, including network-specific bech32 or legacy formats and destination-side EVM 0x account address; 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.
The provider waits for its required source confirmation depth. The account-chain transaction and the Bitcoin transaction are separate records.
An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract.
BTC is listed as the native representation on Bitcoin; BTC is used for network gas. A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth. A native BTC deposit spends selected UTXOs, pays a BTC miner fee, can create change, and advances through Bitcoin confirmations.
ARB is a contract representation on Ethereum at 0xb50721bcf8d664c30412cfbc6cf7a15145234ad1. ETH, not ARB, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
A native BTC deposit spends selected UTXOs, pays a BTC miner fee, can create change, and advances through Bitcoin confirmations. On receipt, A receiving wallet should show the exact ARB contract on the destination. Receipt does not fund ETH gas for later token movement.
BTC is the deposited native-asset input; ARB is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
Requirements are checked for the live BTC Bitcoin to ARB Ethereum 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.
