Sui Wallets and the Ethereum to Arbitrum Route

Why this matters on Sui

Ethereum-to-Arbitrum transfers can be useful for moving activity to an L2. The key checks are the supported token, bridge route, fees, and destination balance.

Sui uses an object-centric model that differs from the account and token conventions of EVM networks.

Sui does not follow standard EVM conventions. Address formats, token identifiers and approval mechanics differ, so EVM-oriented checklists and tools should only be applied to Sui after confirming they are supported.

Sui and this route

Sui is neither end of the Ethereum to Arbitrum route, but a wallet that uses Sui often holds balances on those networks too. If your assets are on Sui, they would first have to be on Ethereum for this route to apply.

Leaving Ethereum

Ethereum gas can make very small balance movements uneconomical, so compare total execution cost with the balance value. Pay close attention to contract approvals, transaction details and the exact domain used to initiate a transaction.

Arriving on Arbitrum

Confirm the Arbitrum token contract rather than assuming an identical ticker represents the same asset everywhere. Compare L2 transaction costs with any bridge or liquidity costs required to reach the destination.

Sui: what to pay attention to

• Costs: Consider network transaction costs and route-specific costs when evaluating small balances.
• Security: Review transaction effects carefully and use trusted wallet interfaces.
• Assets and tokens: Verify the network-specific asset and object details rather than applying EVM assumptions.

A Sui checklist for this topic

• Verify the source network, the destination network and the destination address before signing.
• Compare quotes and the minimum received amount, since the final amount can differ from the estimate.
• Keep enough native balance on the source network to pay for the transaction.
• Do not assume a route from Sui is available; check the current interface and quote.

Bridge from Sui

Consider network transaction costs and route-specific costs when evaluating small balances. On the Aptos side: verify the network-specific asset representation and account details.

The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
