 1 | # Ethereum XCM Message Builder
 2 | This repository contains *Ethereum* smart contracts for [Snowbridge](https://github.com/Snowfork/snowbridge) that creates *XCMv3* messages to be sent via *BridgeHub* to *Polkadot*.
 3 | 
 4 | ## Setup
 5 | 
 6 | ### Foundry
 7 | **Foundry** is a blazing fast, portable and modular toolkit for *Ethereum* application development written in Rust.
 8 | 
 9 | **Foundry** consists of:
10 | - *Forge*: *Ethereum* testing framework;
11 | - *Cast*: Swiss army knife for interacting with *EVM* smart contracts, sending transactions and getting chain data;
12 | - *Anvil*: local Ethereum node;
13 | 
14 | To install **Foundry**, follow the instructions from the [webpage](https://getfoundry.sh/).
15 | 
16 | ### Dependencies
17 | ```sh
18 | git submodule update --init --recursive
19 | forge install
20 | ```
21 | 
22 | ## Build the project
23 | ```sh
24 | forge build
25 | ```
26 | 
27 | ## Format code
28 | ```sh
29 | forge fmt
30 | ```
31 | 
32 | ## Run tests
33 | ```sh
34 | forge test
35 | ```
36 | 
37 | ## Deploy locally
38 | 
39 | ### Run local node
40 | At first, run a single local node with *anvil* using a script:
41 | ```sh
42 | ./node.sh
43 | ```
44 | 
45 | ### Deploy smart contract
46 | To deploy smart contracts, use dedicated shell script:
47 | ```sh
48 | ./deploy.sh
49 | ```
