# LayerZeroV2 DVN Setup
This tool sets up the Blockdaemon DVN (oracle) for an Oapp.
### Requirements
This is a Typescript project. Npm as package manager and node. Tested with npm v10.2.4, node 21.5.0. We recommend using [nvm](https://github.com/nvm-sh/nvm) for node version management.
## Getting started
Our DVN currently supports the following chains:
| **Chain** | **Endpoint ID** | **Env variable NETWORK** | **DVN Address** |
|------------------|-----------------|--------------------------|------------------------------------------|
| Ethereum (mainnet) | 30101 | ethereum | 0x7E65BDd15C8Db8995F80aBf0D6593b57dc8BE437 |
| Avalanche (mainnet)| 30106 | avalanche | 0xFfe42DC3927A240f3459e5ec27EAaBD88727173E |
| Polygon (mainnet) | 30109 | polygon | 0xa6F5DDBF0Bd4D03334523465439D301080574742 |
| Optimism (mainnet) | 30111 | optimism | 0x7B8a0fD9D6ae5011d5cBD3E85Ed6D5510F98c9Bf |
| Fantom (mainnet) | 30112 | fantom | 0x313328609a9C38459CaE56625FFf7F2AD6dcde3b |
| Arbitrum (mainnet) | 30110 | arbitrum | 0xddaa92ce2d2fac3f7c5eae19136e438902ab46cc |
| BNB Smart Chain (mainnet) | 30102 | bnb | 0x313328609a9c38459cae56625fff7f2ad6dcde3b |
| Base (mainnet, lzRead only) | 30184 | base | 0x41ef29f974fc9f6772654f005271c64210425391 |
### Running the tool
1. Install node 21.5.0 (using nvm: `nvm install 21.5.0 && nvm use 21.5.0`)
2. Install the dependencies with `npm install`.
3. Copy the environment variables with `cp .env.example .env`.
4. Populate the variables, including your Blockdaemon API Key (BLOCKDAEMON_API_KEY), the private key that you will be using to sign transactions in the form of a mnemonic (MNEMONIC), the address of your LayerZero v2 application (OAPP_ADDRESS), the network you are operating on (SOURCE_NETWORK), and the destination/target network (TARGET_NETWORK). Make sure to choose a supported network, according to the above table.
5. If you need, set the message library address (MESSAGE_LIB_ADDRESS). We are using the default library. [Deployed Endpoints, Message Libraries, and Executors can be consulted within LZ's official docs](https://docs.layerzero.network/v2/developers/evm/technical-reference/deployed-contracts).
6. Run the main script with `npx ts-node src/main/main.ts`. The script waits two minutes before confirming a change in the oracle, to accommodate for finalization times.
