This document details how to upgrade your Solana OFT program.

Notes

program ID == program address. The terms can be used interchangeably.
you will need the Squads Vault address which is the current OFT Program's Update Authority

Instructions

Prepare the updated code

title	LayerZero V2 Solana OApp Reference
sidebar_label	Solana OApp
audience	Solana smart-contract engineers who already understand Anchor basics and the LayerZero V2 protocol on EVM.
goal	Show every moving piece you must implement to make a Solana program behave like an OApp (Omnichain Application) under LayerZero’s Executor / DVN flow.

import ZoomableMermaidV2 from '@site/src/components/ZoomableMermaidV2';

The OApp Standard provides developers with a generic message passing interface to send and receive arbitrary pieces of data between contracts existing on different blockchain networks.

This is instructions set 2 of 3.

hyperEVM

You have already uploaded the deployments, so this step is done.
Amend hardhat.config.ts
- Note: https://rpc.hyperliquid-mainnet.xyz/evm might not work anymore. Either replace it or set an env var for RPC_URL_HYPEREVM_MAINNET. https://hyperliquid.drpc.org seems to be working at time of writing.
- 2b. add the following into config.networks:
```
'base-mainnet': {
    eid: EndpointId.BASE_V2_MAINNET,
```

	function logDifference(arr1, arr2) {

	let difference = arr1.filter(
	x => arr2.indexOf(x) == -1)
	.concat(arr2.filter(
	x => arr1.indexOf(x) == -1)
	);

	if (difference.length < 1) return []; // if no difference return empty array
	return difference;

	const politicians = require('./politicians.json')
	const promises = require('./promises.json') // live promises

	const result = {
	promisesWithLivePoliticians: {
	total: 0
	},
	promisesWithOfflinePoliticians: {
	total: 0
	}

	// in index.js

	...

	async function handler(event, context) {
	try {
	return handlerService.call(event, context, { AWS })
	} catch (e) {
	if (process.env.NODE_ENV === 'local') throw e
	throw JSON.stringify(e)
