validator

Offical repo for the Ionize asset bridge. Please note that this is a demo version, which currently supports:

  • Bi-directional swaps between Ethereum Sepolia and Stellar testnet
  • Assets that can be swapped:
    • Ethereum Sepolia: USDC, USDT
    • Stellar testnet: USDC

Requirements

  • Supported architectures: Linux arm64 & amd64
  • Memory (RAM): >16 GB (if you want to run an Ethereum node locally)
  • Storage (Disk space): >80 GB (if you want to run an Ethereum node locally)
  • Docker Compose

Setup

Step 1: Clone the repo

git clone [email protected]:ionizedman/validator.git &&

cd validator

Step 2: Configure your validator

touch .env && cp .env.base .env

Add the vault addresses and keys in the command below, then run it in your terminal.

{
    # Add Ethereum vault address
    echo "ETHEREUM_VAULT_ADDRESS=YOUR_ETHEREUM_ADDRESS"
    
    # Add Ethereum vault private key
    echo "ETHEREUM_VAULT_PRIVATE_KEY=YOUR_ETHEREUM_PRIVATE_KEY"

    # Add Stellar vault address
    echo "STELLAR_VAULT_ADDRESS=YOUR_STELLAR_ADDRESS"
    
    # Add Stellar vault secret key
    echo "STELLAR_VAULT_SECRET_KEY=YOUR_STELLAR_SECRET_KEY"
    
    cat .env
} > .env.tmp && mv .env.tmp .env

Step 3 (Optional): Use a remote Ethereum node

Although it is important to run your own ethereum node, however, if you prefer to rely on a remote provider (e.g. Infura, QuickNode), please run this in your terminal:

NEW_ETHEREUM_HTTP="<Add your provider's HTTP endpoint URL here>"
NEW_ETHEREUM_WS="<Add your provider's Websocket URL here>"

awk -v new_ethereum_http="$NEW_ETHEREUM_HTTP" -v new_ethereum_ws="$NEW_ETHEREUM_WS" '
BEGIN {
    FS="="
    OFS="="
}
$1 == "ETHEREUM_HTTP" {
    $2 = new_ethereum_http
}
$1 == "ETHEREUM_WS" {
    $2 = new_ethereum_ws
}
{
    print
}' .env > .env.tmp && mv .env.tmp .env

Step 4: Run the validator

docker compose -p ionize up -d

Note: It takes some time to syc up on both networks. You can monitor progress by accessing your docker container logs.

Once syncing is complete on Stellar and Ethereum networks, You can access the Ionize service via:

  • REST API endpoints:

    • GET status: http://localhost:8080/status
    • GET transactions: http://localhost:8080/transactions

  • Websocket connection:

    • Stream live transactions: ws://localhost:3000
