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.

WBTC input versus SUI output representation

WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. Native SUI receipt creates Sui coin objects that can fund later gas. A smart-contract token outside Sui does not become a native object.

WBTC unwrap or exchange input check

WBTC is a custodial tokenized Bitcoin representation on smart-contract networks. Its transfers use token contracts and approvals rather than native Bitcoin inputs and outputs. On this route WBTC is the source token on Avalanche. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
