Building Offline

To build a transaction block offline (with no client required), you need to fully define all of your input values and gas configuration (see the following example). For pure values, you can provide a Uint8Array which is used directly in the transaction. For objects, you can use the Inputs helper to construct an object reference.

import { Inputs } from '@mysten/sui.js/transactions';
 
// for pure values
txb.pure(pureValueAsBytes);
 
// for owned or immutable objects
txb.object(Inputs.ObjectRef({ digest, objectId, version }));
 
// for shared objects
txb.object(Inputs.SharedObjectRef({ objectId, initialSharedVersion, mutable }));

You can then omit the client object when calling build on the transaction. Any required data that is missing throws an error.
