Sui to Ethereum: object and account boundary

A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. Sui and Ethereum 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.

SUI input versus POL output representation

Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

Mistakes specific to SUI Sui to POL Ethereum

Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Ethereum; running out of SUI before the source transaction is submitted; assuming other and evm addresses are interchangeable. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

SUI input identity and handling

Sui is classified as a native asset for this route. SUI uses a native asset on Sui. The Sui side is contract-tracked rather than a native gas balance. Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model.

POL output identity and receiving

POL (ex-MATIC) is classified as a governance or utility token for this route. POL uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

Private Route for SUI → POL

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

Swap SUI on Sui to POL on Ethereum FAQs

How does the Sui coin-object side differ from the other network?

Sui uses Move coin types and objects with SUI gas. The other side follows EVM execution, so addresses and token identifiers are not interchangeable.

What exactly leaves Sui as SUI?

SUI is listed as the native representation on Sui; SUI is used for network gas. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model.

What exactly arrives on Ethereum as POL?

POL is a contract representation on Ethereum at 0x455e53cbb86018ac2b8092fdcd39d8444affc3f6. ETH, not POL, pays gas unless both symbols are the same. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

Why does the SUI to POL direction matter?

Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. On receipt, On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

What changes between the source and destination asset roles?

SUI is the deposited native-asset input; POL is the quoted token output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending SUI?

Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. An Ethereum receipt is an L1 native ETH balance or ERC-20 contract event; later token movement can require ETH gas and a new approval for another contract. On Polygon PoS, native POL can support later gas; a POL contract on another network does not inherit that native function.

What funds the Sui source transaction?

SUI is the native gas asset for Sui. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. SUI is recorded as native on this source.

Can I swap SUI on Sui to POL on Ethereum without KYC?
