Sui to Arbitrum: 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 Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Sui and Arbitrum 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 TRX 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 TRX receipt belongs to a Tron address and can support network resources; tokenized TRX on another ledger cannot supply Tron bandwidth or energy.

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 Sui. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.

Mistakes specific to WBTC Sui to TRX Arbitrum

Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Arbitrum; running out of SUI before the source transaction is submitted; assuming other and evm addresses are interchangeable; treating a wrapped token as the native gas asset. A Sui source consumes or mutates Move coin objects, uses a Sui address, and spends SUI for gas and storage-related execution. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. An Arbitrum receipt appears on the Nitro L2 ledger under an Arbitrum token contract or native ETH balance; later spending needs Arbitrum ETH while L1 settlement continues separately. Native TRX receipt belongs to a Tron address and can support network resources; tokenized TRX on another ledger cannot supply Tron bandwidth or energy.

Native TRX receipt belongs to a Tron address and can support network resources; tokenized TRX on another ledger cannot supply Tron bandwidth or energy.

Private Route for WBTC → TRX

Sui account, object, transaction-effect, and fee activity remain public, and Arbitrum wallet, token-transfer, contract, log, and gas activity remain public. For this WBTC on Sui to TRX on Arbitrum 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.
