Choose the BTC asset and Bitcoin network you currently hold.
Check the estimated output, fees, timing, and Arbitrum destination network.
Open the live route and follow the exact deposit instructions.
Use the receipt and status page until the destination funds arrive.
Bitcoin uses a UTXO source model while Arbitrum uses a non-UTXO destination model. Native Bitcoin deposits require a supported Bitcoin address, confirmation-aware input handling, and attention to change outputs; an EVM token labeled BTC or WBTC is not native BTC.
Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Arbitrum. 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 is a L1 Bitcoin Script network in the Bitcoin ecosystem. BTC pays source-side network gas on Bitcoin. Native Bitcoin address supported by the route, including network-specific bech32 or legacy formats A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth.
Bitcoin source execution occurs on L1, while Arbitrum delivery occurs on a separate L2 ledger that settles to ethereum. BTC pays source gas and ETH is the destination gas asset; identical-looking wallet addresses do not merge the balances or transaction histories.
The live quote lists the exact Bitcoin input asset and Arbitrum output representation. A shared ticker is not proof of a shared contract, native ledger, decimals, or wallet support.
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. A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth. 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 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 ARB 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.
Bitcoin is the UTXO source and BTC fees apply before the provider credits Arbitrum. Tokenized BTC on an account chain is not the same ledger asset.
The live route lists assets supported in this direction. Confirm that the selected source representation has an explicit Arbitrum output before depositing.
A Bitcoin source spends UTXOs, creates a fee-bearing transaction and possible change, and waits for the route provider’s confirmation depth. 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. The bridge output does not automatically fund every later gas need.
EVM 0x account address Do not substitute a Bitcoin address merely because a wallet displays both networks.
Sending on a network other than Bitcoin, selecting a representation not listed by the quote, or entering an address invalid for Arbitrum can prevent normal detection or receipt.
Requirements are checked for the live BTC Bitcoin to 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.
