**Abstract**  
Perform an test upgrade on a testnet deployment of Sui Lazer contract to ensure that the process works correctly.  
The update itself only changes the included version number - goal is to test whether the contract can successfully execute governance action.

**Rationale**  
Sui Lazer contract only allows maintenance through Wormhole’s [Verified Action Approvals](https://wormhole.com/docs/protocol/infrastructure/vaas/#verified-action-approvals) (VAAs) tied to specific emitter address and chain. We’ve tested the process with dummy emitter tied to ordinary wallet, but this flow doesn’t test implementation of proposal submitting and execution.

**Description**  
Proposal should emit a single Wormhole message targeted to Sui chain, with update version 2 and digest of build of current version of the contract, with slight modification (see below), available after this commit in `pyth-crosschain` repository: [https://github.com/pyth-network/pyth-crosschain/commit/d6dd7841edfd9fd4925b3b5477aa28c212968133](https://github.com/pyth-network/pyth-crosschain/commit/d6dd7841edfd9fd4925b3b5477aa28c212968133)

**Implementation plan**

- Contract implementation: [https://github.com/pyth-network/pyth-crosschain/tree/d6dd7841edfd9fd4925b3b5477aa28c212968133/lazer/contracts/sui](https://github.com/pyth-network/pyth-crosschain/tree/d6dd7841edfd9fd4925b3b5477aa28c212968133/lazer/contracts/sui)

- Proposal ID: [8tLtUiWjJ4jn8u4RwDuHjqBc3L6wLwhQC8iXDfT2FSq2](https://proposals.pyth.network/?tab=proposals&status=active&proposal=8tLtUiWjJ4jn8u4RwDuHjqBc3L6wLwhQC8iXDfT2FSq2)

**Proposal verification**

- Install [pnpm](https://pnpm.io/installation), [jq](https://jqlang.org/download/) and [suiup](https://github.com/MystenLabs/suiup)

- Install latest testnet version of Sui tools through command line:

```auto
suiup install sui

```

- Clone the `pyth-crosschain` repository and build `contract_manager`:

```auto
git clone https://github.com/pyth-network/pyth-crosschain.git
cd pyth-crosschain/contract_manager
pnpm install && pnpm turbo build

```

- Modify `pyth-crosschain/lazer/contracts/sui/sources/pyth_lazer.move` by appending the following lines (used to avoid accidental use of this proposal on mainnet):

```auto

public struct ThisIsATestContractMeantForTestnetOnly {}

```

- Temporarily modify the `pyth-crosschain/contract_manager/check_proposal.ts` script to check the testnet contract instead of a mainnet one:

- Within `pyth-crosschain/contract_manager` directory, run the `check_proposal` script:
