Prerequisites

This repository makes use of yarn, nodejs, and requires version node v16. To install node.js binaries, installers, and source tarballs, please visit https://nodejs.org/en/download/. Once node.js is installed you may proceed to install yarn:

npm install --global yarn

Great! Now your Node environment is ready! 🚀🚀

Run locally 💻

Once the development environment is set up, you may proceed to install the required dependencies and run the dapp locally.

1. Clone this repo

   git clone git@github.com:webb-tools/webb-dapp.git && cd webb-dapp

2. Install dependencies by yarn

   yarn install

3. Start the dapp:

   yarn start:dapp

Visit http://localhost:3000/ to see the Webb Dapp UI! 🕸️ 🚀

Use locally cached substrate fixtures

• Download the proving key from proving_key_uncompressed.bin.
• Save it to packages/apps/public/cached-fixtures , the file name should be proving_key_uncompressed.bin .
• Run the dApp with yarn start:localDapp

Usage

Quick Start ⚡

Eager to try out the Webb Dapp and see it in full action? You can setup a local Mixer with a local Relayer or try running a local EVM bridge with the Dapp!

Mixer setup with local substrate node and Relayer

Follow the below steps to get up and running or follow the detailed how-to guide here.

Setup local nodes

1. Clone the protocol-substrate repo:

 git clone https://github.com/webb-tools/protocol-substrate

2. We are using ORML fork, and fixed zero knowledge keys to run the mixers. Run:

# populates fixed zero knowledge keys
git submodule update --init

3. Build the webb-standalone-node by running:

cargo build --release -p webb-standalone-node

4. Startup two standalone nodes in other terminal instances:

# Run in terminal 1
./target/release/webb-standalone-node --dev --alice --node-key 0000000000000000000000000000000000000000000000000000000000000001 --ws-port=9944 --rpc-cors all

# Run in terminal 2
./target/release/webb-standalone-node --dev --bob --port 33334 --tmp --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/12D3KooWEyoppNCUx8Yx66oV9fJnriXwCcXwDDUA2kj6vnc6iDEp

Great! Now you have 2 local protocol-substrate nodes running! Now let's setup a local relayer. 🚀

Relayer

1. Clone the relayer:

git clone https://github.com/webb-tools/relayer.git

2. Build the relayer:

cargo build --release

3. Run with the local substrate configuration:

./target/release/webb-relayer -c config/local-substrate -vv

Congrats! 🎉 You now have a local mixer setup that you can use with this webb dapp locally!

EVM Bridge setup with local evm node and Relayer

Follow the below steps to get up and running. 🏃

Setup local EVM node

1. Clone the local testnet:

git clone https://github.com/webb-tools/evm-localnet

2. Populate fixed zero knowledge keys by running:

git submodule update --init

3. Install dependencies:

  yarn install

4. Start the local testnet with:

yarn start

Great! Now you have a local EVM node running! Now let's setup a local relayer. 🚀

Relayer

1. Clone the relayer:

git clone https://github.com/webb-tools/relayer.git

2. Build the relayer:

cargo build --release

3. Run with the local substrate configuration:

./target/release/webb-relayer -c config/local-testnet -vv

Congrats! 🎉 You now have a local bridge setup that you can use with this webb dapp locally!
