GrpcTransactionExecutor extension

Automates gas preparation for the gRPC path so a Transaction can be built, signed and executed without a legacy JSON-RPC client.

Fills, when unset:

  • gas price -> getReferenceGasPrice
  • gas payment -> a Coin<SUI> from listOwnedObjects
  • gas budget -> estimated from a simulateTransaction dry run

Object resolution for moveCall arguments (the builder's client-backed resolveObjectReferences) is out of scope here; provide fully-resolved object references for those cases.
