Sui to Polygon: 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. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. Sui and Polygon 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 USDC output representation

Native SUI is selected from Sui coin objects and can fund gas; tokenized SUI outside Sui does not use the object model. 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 Polygon representation. The route converts a native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

Mistakes specific to SUI Sui to USDC Polygon

Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Polygon; running out of SUI before the source transaction is submitted; assuming other and evm addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract. 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. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

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.

USDC output identity and receiving

USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Polygon. The recorded Polygon representation uses 6 decimal places. 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 SUI → USDC

Sui account, object, transaction-effect, and fee activity remain public, and Polygon wallet, token-transfer, contract, log, and gas activity remain public. For this SUI on Sui to USDC on Polygon 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 USDC on Polygon 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 Polygon as USDC?

USDC is a contract representation on Polygon with 6 decimals at 0x3c499c542cEF5E3811e1192ce70d8cC03d5c3359. POL, not USDC, pays gas unless both symbols are the same. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Why does the SUI to USDC 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, The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

What changes between the source and destination asset roles?

SUI is the deposited native-asset input; USDC is the quoted stablecoin 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. A Polygon PoS receipt follows Polygon token contracts and checkpointed execution; later movement uses POL gas rather than Ethereum L1 gas. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

Which stablecoin contract must this route match?
