What you need to know

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.

WBTC input versus WBTC 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

WBTC keeps its ticker while changing ledgers

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Sui. The recorded Sui representation uses 8 decimal places. The Sui side is contract-tracked rather than a native gas balance. Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Ethereum. The Ethereum side is contract-tracked rather than a native gas balance. WBTC leaves as a wrapped contract asset. WBTC arrives as a wrapped contract asset.

Sui to Ethereum bridge mistakes

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; 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 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Private Route for WBTC → WBTC

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

Sui to Ethereum FAQs

Which side uses Sui coin objects and SUI gas?

Sui is the Sui side. Its Move coin types, address, objects, and SUI gas do not transfer as EVM contract metadata.

What WBTC representation leaves Sui?

WBTC is a contract representation on Sui with 8 decimals at 0x027792d9fed7f9844eb4839566001bb6f6cb4804f66aa2da6fe1ee242d896881::coin::COIN. SUI, not WBTC, pays gas unless both symbols are the same. 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.

What WBTC representation arrives on Ethereum?

WBTC is a contract representation on Ethereum at 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599. ETH, not WBTC, pays gas unless both symbols are the same. 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. WBTC arrives as a wrapper-contract token and must not be sent onward to a native Bitcoin address without an explicit unwrap or bridge path.

Does the same WBTC ticker guarantee the same ledger form?

No. This bridge keeps the asset intent while moving between a WBTC wrapped token and a WBTC wrapped token. Match the source and output details in the live quote.

Which gas balances matter for this bridge?

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. The bridge output does not automatically fund every later gas need.

What destination address should be used?

EVM 0x account address Do not substitute a Sui address merely because a wallet displays both networks.

What wrong-direction mistake can prevent delivery?

Sending on a network other than Sui, selecting a representation not listed by the quote, or entering an address invalid for Ethereum can prevent normal detection or receipt.

Can I bridge WBTC from Sui to Ethereum without KYC?

Requirements are checked for the live WBTC Sui to Ethereum quote. Verification requirements can depend on the provider, amount, jurisdiction, and current route. Sasquatch does not verify this route as universally no-KYC; check the live flow before continuing.
