Optimism to Sui: object and account boundary

An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Optimism 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 SOL 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 SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

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

Mistakes specific to WBTC Optimism to SOL Sui

Route-specific mistakes include sending on a network other than Optimism; using a destination that is not valid for Sui; running out of ETH before the source transaction is submitted; assuming evm and other addresses are interchangeable; treating a wrapped token as the native gas asset. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

WBTC input identity and handling

Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Optimism. The recorded Optimism representation uses 8 decimal places. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

SOL output identity and receiving

Solana is classified as a native asset for this route. SOL uses a network-specific contract asset on Sui. The recorded Sui representation uses 8 decimal places. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Private Route for WBTC → SOL

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

Swap WBTC on Optimism to SOL on Sui FAQs

How does the Sui coin-object side differ from the other network?

Sui uses Move coin types and objects with SUI gas. The other side follows EVM execution, so addresses and token identifiers are not interchangeable.

What exactly leaves Optimism as WBTC?

WBTC is a contract representation on Optimism with 8 decimals at 0x0555E30da8f98308EdB960aa94C0Db47230d2B9c. ETH, not WBTC, pays gas unless both symbols are the same. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.

What exactly arrives on Sui as SOL?

SOL is a contract representation on Sui with 8 decimals at 0xb7844e289a8410e50fb3ca48d69eb9cf29e27d223ef90353fe1bd8e27ff8f3f8::coin::COIN. SUI, not SOL, pays gas unless both symbols are the same. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Why does the WBTC to SOL direction matter?

WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. On receipt, Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

What changes between the source and destination asset roles?

WBTC is the deposited wrapped-asset input; SOL is the quoted native-asset output. Source allowance or native-spend rules and destination wallet/representation checks are evaluated separately.

What should be matched before sending WBTC?

WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Native SOL receipt uses a Solana address and can fund later fees; wrapped SOL uses an SPL token account and tokenized SOL elsewhere is not native.

Can the wrapped asset pay native network gas?

No. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer. An OP Mainnet source uses sequenced OP Stack execution and ETH gas; ordinary route processing is not the same as the canonical L2 withdrawal delay. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance.

Can I swap WBTC on OP Mainnet to SOL on Sui without KYC?

Requirements are checked for the live WBTC OP Mainnet to SOL Sui 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.
