Choose the USDC asset and Arbitrum network you currently hold.
Check the estimated output, fees, timing, and Base destination network.
Open the live route and follow the exact deposit instructions.
Use the receipt and status page until the destination funds arrive.
The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset. The same stablecoin ticker does not make the two network records or contracts interchangeable.
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.
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.
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.
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.
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. On an Arbitrum source, the Nitro sequencer records L2 execution before Ethereum settlement completes; ETH funds gas and ERC-20 inputs can need approval. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset. 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 USDC 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.
USDC is a contract representation on Arbitrum at 0xaf88d065e77c8cc2239327c5edb3a432268e5831. ETH, not USDC, 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. The source wallet sends the exact USDC native or contract representation selected by the route; contract USDC can require approval and the chain’s native gas asset.
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.
No. This bridge keeps the asset intent while moving between a USDC contract token and a USDC contract token. Match the source and output details in the live quote.
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 bridge output does not automatically fund every later gas need.
EVM 0x account address Do not substitute a Arbitrum address merely because a wallet displays both networks.
Sending on a network other than Arbitrum, selecting a representation not listed by the quote, or entering an address invalid for Base can prevent normal detection or receipt.
Requirements are checked for the live USDC Arbitrum to Base 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.
