MovePackageService/ListPackageVersions - SUI

Example code for the MovePackageService/ListPackageVersions gRPC method. Complete guide on how to use MovePackageService/ListPackageVersions gRPC method in GetBlock Web3 documentation.

Returns all versions of a Move package. Move packages on Sui can be upgraded; each upgrade produces a new package object with an incremented version. This method returns the history.

Service: sui.rpc.v2.MovePackageService Proto file: sui/rpc/v2/move_package_service.proto Full method path: sui.rpc.v2.MovePackageService/ListPackageVersions

Request Fields

Field	Type	Required	Description
package_id	ObjectId	Yes	32-byte ID of any version of the package (typically the original)
page_size	uint32	No	Maximum versions per page

Rust (tonic)

Response Example

Responses are encoded in Protocol Buffers binary format on the wire. The example below shows the protobuf JSON encoding for readability.

{
    "versions": [
        {
            "package_id": "0x0000000000000000000000000000000000000000000000000000000000000002",
            "version": "1",
            "previous_transaction": "8WmKqcRkV5JZw8gEjGyzVxRYHnDvKmJsxLBp7t6vNqrA"
        },
        {
            "package_id": "0xffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff",
            "version": "2",
            "previous_transaction": "Q9LkBpZHvJxMsnNzVxRYHnDvKmJsxLBp7t6vNqRAmK"
        }
    ],
    "next_page_token": ""
}

Response Fields

Field	Type	Description
versions	repeated PackageVersion	Package versions, ordered by version number
versions[].package_id	ObjectId	Object ID of this version (each upgrade produces a new object)
versions[].version	string	Version number
versions[].previous_transaction	string	Digest of the transaction that published this version
next_page_token	string	Pagination cursor; empty when no more pages

Use Cases

• Auditing package upgrade history

• Detecting compromised packages by tracking unexpected upgrades

• Tooling that needs to pin against a specific package version

Error Handling

gRPC uses status codes rather than JSON-RPC numeric error codes. The most relevant for this method:

Status Code	Numeric	Cause
UNAUTHENTICATED	16	Missing or invalid <ACCESS-TOKEN> in the URL path
INVALID_ARGUMENT	3	Request fields are missing, malformed, or fail validation
UNAVAILABLE	14	Node is overloaded or temporarily unable to handle the request — retry with backoff
DEADLINE_EXCEEDED	4	Request did not complete within the timeout window
RESOURCE_EXHAUSTED	8	Rate limit exceeded for your plan
NOT_FOUND	5	Package does not exist

SDK Integration

@mysten/sui (TypeScript)

// The Mysten Labs TypeScript SDK provides higher-level wrappers around the
// gRPC API. Use @mysten/sui for typed client access:

import { SuiClient } from '@mysten/sui/client';

const client = new SuiClient({
    url: 'https://go.getblock.io/<ACCESS-TOKEN>/'
});

// Refer to the @mysten/sui API reference for the typed wrapper of this method;
// raw gRPC call to sui.rpc.v2.MovePackageService/ListPackageVersions is available as shown in the
// Request Example tabs above.

pysui (Python)

# pysui is the community-maintained Python SDK for Sui (Mysten Labs does not
# yet publish an official Python SDK). For raw gRPC access, use grpcio with
# the generated proto stubs as shown in the Request Example tabs above.

from pysui import SuiConfig, SyncClient

config = SuiConfig.user_config(
    rpc_url='https://go.getblock.io/<ACCESS-TOKEN>/'
)
client = SyncClient(config)

# Consult pysui docs for the wrapper of MovePackageService.ListPackageVersions.
