MessageTransmitterV2,
TokenMessengerMinterV2, StablecoinHandler, and CctpExtensions. The Sui
CCTP implementation uses
Programmable Transaction Blocks (PTBs)
to compose the required function calls atomically in a single transaction.
For working end-to-end examples, see
Transfer USDC between Sui and Arc.
Package addresses
Package IDs identify deployed Move packages. Use them in function call
targets (for example,
{packageId}::module::function). State object IDs
identify onchain shared objects, such as configuration or shared state, and are
passed as arguments when a transaction interacts with protocol state.Testnet

CctpExtensions has no state object ID on either network. Callers of
CctpExtensions do not need to pass a state object argument.
