Sui Wallets and the Ethereum to Polygon Route

Why this matters on Sui

Ethereum-to-Polygon transfers require attention to token representation and source gas. A route can be technically valid while still being uneconomical for a very small 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 Polygon 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 Polygon

Confirm that the token is held on Polygon and verify its contract before moving or swapping it. Compare Polygon transaction costs with bridge and liquidity costs when consolidating small balances.

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

• 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.
• Send a small test amount first if the route or address is new to you.

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.
