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.
DAI input versus WBTC output representation
DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical. 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.
Converting stablecoin DAI into WBTC
DAI is a crypto-backed dollar-oriented stablecoin whose canonical and bridged contracts vary by network. Its peg design does not make two network representations interchangeable. The source is a stablecoin contract or recorded native representation, while WBTC is classified as wrapped-asset. Check the quoted output rather than assuming a one-dollar source unit fixes the destination amount.
WBTC wrapped-token output 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 destination token on Sui. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to DAI Optimism to WBTC 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; selecting a stablecoin by ticker without checking its network contract; 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. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.

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.
DAI input identity and handling
Dai is classified as a stablecoin for this route. DAI uses a network-specific contract asset on Optimism. The recorded Optimism representation uses 18 decimal places. DAI leaves through its network-specific stablecoin contract and can require approval; the collateral design does not make a bridged DAI contract canonical.
WBTC output identity and receiving
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. 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.
