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 POL can be delivered on Arbitrum.
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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Bitcoin confirmations and Arbitrum transaction finality are separate milestones.
Route-specific mistakes include sending on a network other than Bitcoin; using a destination that is not valid for Arbitrum; 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
POL (ex-MATIC) is classified as a governance or utility token for this route. POL uses a network-specific contract asset on Arbitrum. The recorded Arbitrum representation uses 18 decimal places. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
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 Arbitrum wallet, token-transfer, contract, log, and gas activity remain public. For this BTC on Bitcoin to POL on Arbitrum 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately.
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.
POL is a contract representation on Arbitrum with 18 decimals at 0x044d8e7F3A17751D521efEa8CCf9282268fE08CC. ETH, not POL, pays gas unless both symbols are the same. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
A native BTC deposit spends selected UTXOs, pays a BTC miner fee, can create change, and advances through Bitcoin confirmations. On receipt, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.
BTC is the deposited native-asset input; POL 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 POL Arbitrum 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.
