Solana to Sui: object and account boundary
A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. A Sui receipt creates or updates Move coin objects at a Sui address; later object operations require SUI gas rather than an EVM allowance. Solana 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 USDT 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
Receiving stablecoin USDT
USDT is issued through ERC-20, TRC-20, SPL, and other network-specific contracts. The ticker does not determine the token standard, contract, issuer controls, or destination address model. The destination wallet must support the exact Sui representation. The route converts a wrapped-asset source into a stablecoin balance; the destination ticker alone is not a contract check.
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 Solana. Its token balance, approvals, and contract transfer behavior are separate from the native coin used for network gas.
Mistakes specific to WBTC Solana to USDT Sui
Route-specific mistakes include sending on a network other than Solana; using a destination that is not valid for Sui; running out of SOL before the source transaction is submitted; assuming solana and other addresses are interchangeable; selecting a stablecoin by ticker without checking its network contract; treating a wrapped token as the native gas asset. A Solana source signs over accounts or token accounts, identifies SPL assets by mint, and spends SOL for transaction fees. 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. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
WBTC input identity and handling
Wrapped Bitcoin is classified as a wrapped asset for this route. WBTC uses a wrapped contract asset on Solana. The Solana side is contract-tracked rather than a native gas balance. WBTC leaves through a custodial wrapper contract with token approval and source-chain gas; no native Bitcoin UTXO is spent by that transfer.
USDT output identity and receiving
Tether is classified as a stablecoin for this route. USDT uses a network-specific contract asset on Sui. The recorded Sui representation uses 6 decimal places. Confirm whether the output is ERC-20, TRC-20, SPL, or another USDT standard; a wallet supporting one standard may not credit another.
