Sui to Solana: 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. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. Sui and Solana 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.
WETH input versus USDC output representation
WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
Receiving stablecoin USDC
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 destination wallet must support the exact Solana representation. The route converts a token source into a stablecoin balance; the destination ticker alone is not a contract check.
WETH unwrap or exchange input check
WETH is a contract wrapper for ETH. It can be transferred as a token but cannot replace the native gas balance required by the network. On this route WETH 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 WETH Sui to USDC Solana
Route-specific mistakes include sending on a network other than Sui; using a destination that is not valid for Solana; running out of SUI before the source transaction is submitted; assuming other and solana addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; 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. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer. A Solana receipt uses a native SOL balance or SPL token account identified by mint; later token movement and account creation use SOL fees. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
WETH input identity and handling
WETH is classified as a wrapped asset for this route. WETH uses a wrapped contract asset on Sui. The recorded Sui representation uses 8 decimal places. WETH leaves through a wrapper contract and needs native chain gas. A WETH token balance cannot pay the gas required to submit its own transfer.
USDC output identity and receiving
USDC is classified as a stablecoin for this route. USDC uses a network-specific contract asset on Solana. The Solana side is contract-tracked rather than a native gas balance. The wallet must support the destination USDC native label or contract. Receipt does not automatically supply the destination network’s gas asset.
