Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Arbitrum. The recorded Arbitrum representation uses 8 decimal places. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
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 destination wallet must support the exact Base representation. The route converts a wrapped-asset source into a stablecoin balance; the destination ticker alone is not a contract check.
This route crosses two L2 execution environments. Arbitrum settles to ethereum, while Base settles to ethereum; each side keeps its own gas balance, token contracts, transaction hash, and settlement progress.
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Base. The Base side is contract-tracked rather than a native gas balance. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Base is a L2 EVM network in the Ethereum ecosystem. ETH pays destination-side network gas on Base. EVM 0x account address A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.
Arbitrum is a L2 EVM network in the Ethereum ecosystem. ETH pays source-side network gas on Arbitrum. EVM 0x account address On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval.
WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC is the source token on Arbitrum. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Base; running out of ETH before the source transaction is submitted; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Arbitrum wallet, token-transfer, contract, log, and gas activity remain public, and Base wallet, token-transfer, contract, log, and gas activity remain public. For this WBTC on Arbitrum to USDC on Base path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side EVM 0x account address; it does not hide either chain's public records.
WBTC is a contract representation on Arbitrum with 8 decimals at 0x2f2a2543B76A4166549F7aaB2e75Bef0aefC5B0f. ETH, not WBTC, pays gas unless both symbols are the same. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
USDC is a contract representation on Base at 0x833589fcd6edb6e08f4c7c32d4f71b54bda02913. ETH, not USDC, pays gas unless both symbols are the same. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On receipt, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
WBTC is the deposited wrapped-asset input; USDC is the quoted stablecoin output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.
WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
USDC must match the quoted Base representation. A ticker or target price is not enough to identify a token contract.
No. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. A Base receipt belongs to the Base L2 balance and token contract, not Ethereum L1; later activity needs ETH specifically on Base.
