Avalanche to Sui: object and account boundary

An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Avalanche and Sui 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.

AVAX input versus USDT output representation

On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Receiving stablecoin USDT

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. The destination wallet must support the exact Sui representation. The route converts a native-asset source into a stablecoin balance; the destination ticker alone is not a contract check.

Mistakes specific to AVAX Avalanche to USDT Sui

Route-specific mistakes include sending on a network other than Avalanche; using a destination that is not valid for Sui; running out of AVAX before the source transaction is submitted; assuming evm and other addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract. An Avalanche source route uses C-Chain Snowman execution and AVAX gas; X-Chain or P-Chain balances are not valid C-Chain deposits. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

AVAX input identity and handling

Avalanche is classified as a native asset for this route. AVAX uses a native asset on Avalanche. The recorded Avalanche representation uses 18 decimal places. On Avalanche C-Chain, native AVAX funds both the transfer value and gas; on another chain, an AVAX-labelled contract behaves as a token input instead.

USDT output identity and receiving

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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.

Private Route for AVAX → USDT

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