zkSync Era to Sui: object and account boundary

A zkSync Era source executes in EraVM with native account-abstraction behavior and ETH fees before proof settlement to Ethereum. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. zkSync Era 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.

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.
