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.

USDT input versus USDC output representation

The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

USDT and USDC: two stablecoin ledgers

USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. 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 route changes both asset identity and network representation; dollar-oriented pricing does not remove issuer controls, liquidity spread, contract, or receiving-network checks.

Mistakes specific to USDT Sui to USDC 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; 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. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior. 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. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.

USDT input identity and handling

Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Sui. The recorded Sui representation uses 6 decimal places. The input must match the selected ERC-20, TRC-20, SPL, or other USDT representation; each standard has different address, approval, and fee behavior.

USDC output identity and receiving

USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. 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 USDT → USDC

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