create
fun createContract(wasmId: String, address: Address, constructorArgs: List<SCValXdr>? = null, salt: ByteArray? = null): InvokeHostFunctionOperation
Creates an InvokeHostFunctionOperation for creating/deploying a contract.
This operation deploys a contract instance from previously uploaded WASM code, optionally passing constructor arguments to initialize the contract.
Return
An InvokeHostFunctionOperation for creating the contract
Example
// Deploy contract without constructor arguments
val createOp = InvokeHostFunctionOperation.createContract(
wasmId = "abc123...", // 64-character hex string
address = Address(deployerAccountId)
)
// Deploy contract with constructor arguments (e.g., token contract)
val createTokenOp = InvokeHostFunctionOperation.createContract(
wasmId = "def456...",
address = Address(deployerAccountId),
constructorArgs = listOf(
Address(adminId).toSCVal(),
Scv.toUint32(8u), // decimals
Scv.toString("TokenName"),
Scv.toString("TOKEN")
)
