Arbitrum to Sui: object and account boundary

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 Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Arbitrum and Sui use different network identities, gas assets, wallet support, confirmation behavior, and destination conventions. Validate each side independently in the current route.

Sui coin-object and SUI gas requirements

SUI is the native gas asset for Sui. Sui hexadecimal account address with an object-based asset model Coin objects and Move types are not EVM token contracts.

ARB input versus USDC output representation

Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Receiving stablecoin USDC

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 Sui representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.

Mistakes specific to ARB Arbitrum to USDC Sui

Route-specific mistakes include sending on a network other than Arbitrum; using a destination that is not valid for Sui; running out of ETH before the source transaction is submitted; assuming evm and other addresses are interchangeable; 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. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

ARB input identity and handling

Arbitrum is classified as a governance or utility token for this route. ARB uses a network-specific contract asset on Arbitrum. The Arbitrum side is contract-tracked rather than a native gas balance. Sending ARB can require a token allowance, while ETH—not ARB—must fund Arbitrum gas. Verify the outbound ARB contract if the source is not Arbitrum.

USDC output identity and receiving

USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Sui. The Sui 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.

Private Route for ARB → USDC

Arbitrum wallet, token-transfer, contract, log, and gas activity remain public, and Sui account, object, transaction-effect, and fee activity remain public. For this ARB on Arbitrum to USDC on Sui path, Private Route is intended to reduce the direct visible relationship between activity around the source-side EVM 0x account address and destination-side Sui hexadecimal account address with an object-based asset model; it does not hide either chain's public records.
