# Wormhole CLI

This tool is a command line interface to Wormhole.

## Installation

    make install

This installs two binaries, `worm-fetch-governance` and `worm` on your `$PATH`.

To use `worm`, set up `$HOME/.wormhole/.env` with your
private keys, based on `.env.sample` in this folder.

## Usage

```sh
worm [command]

Commands:
  worm generate                             generate VAAs (devnet and testnet
                                            only)
  worm parse <vaa>                          Parse a VAA (can be in either hex or
                                            base64 format)
  worm recover <digest> <signature>         Recover an address from a signature
  worm contract <network> <chain> <module>  Print contract address
  worm rpc <network> <chain>                Print RPC address
  worm evm                                  EVM utilites
  worm submit <vaa>                         Execute a VAA

Options:
  --help     Show help                                                 [boolean]
  --version  Show version number                                       [boolean]
```

Consult the `--help` flag for using subcommands.

### VAA generation

Use `generate` to create VAAs for testing. For example, to create an NFT bridge registration VAA:

```sh
$ worm generate registration --module NFTBridge \
    --chain bsc \
    --contract-address 0x706abc4E45D419950511e474C7B9Ed348A4a716c \
    --guardian-secret cfb12303a19cde580bb4dd771639b0d26bc68353645571a8cff516ab2ee113a0
```

Example creating a token attestation VAA:

```sh
$ worm generate attestation --emitter-chain ethereum \
    --emitter-address 11111111111111111111111111111115 \
    --chain ethereum \
    --token-address 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48 \
    --decimals 6 \
    --symbol USDC \
    --name USDC \
    --guardian-secret cfb12303a19cde580bb4dd771639b0d26bc68353645571a8cff516ab2ee113a0
```

### VAA parsing

Use `parse` to parse a VAA into JSON. For example,

    worm parse $(worm-fetch-governance 13940208096455381020)

will fetch governance VAA `13940208096455381020` and print it as JSON.

```sh

}
```

### Submitting VAAs

Use `submit` to submit a VAA to a chain. It first parses the VAA and figures out
what's the destination chain and module. For example, a contract upgrade contains both the target chain and module, so the only required argument is the network moniker (`mainnet` or `testnet`):

    worm submit $(cat my-nft-registration.txt) --network mainnet

For VAAs that don't have a specific target chain (like registrations or guardian
set upgrades), the script will ask you to specify the target chain.
For example, to submit a guardian set upgrade on all chains, simply run:

```sh
$ worm-fetch-governance 13940208096455381020 > guardian-upgrade.txt
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain oasis
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain aurora
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain fantom
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain karura
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain acala
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain klaytn
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain avalanche
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain polygon
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain bsc
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain solana
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain terra
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain ethereum
$ worm submit $(cat guardian-upgrade.txt) --network mainnet --chain celo
```

The VAA payload type (guardian set upgrade) specifies that this VAA should go to the core bridge, and the tool directs it there.

### info

To get info about a contract (only EVM supported at this time)

```sh
