Sui Wallets and the Base to Arbitrum Route

Why this matters on Sui

Base and Arbitrum are both L2 environments, but that does not make their token contracts interchangeable. Treat the destination token as a network-specific asset.

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 Base 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 Base for this route to apply.

Leaving Base

Consider Base transaction costs together with bridge and route costs when moving small balances. Use trusted interfaces and verify destination network and token before signing.

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

• 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.
• Send a small test amount first if the route or address is new to you.
• Confirm that the token you hold on Sui is supported for the route you are reading about.

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.
