Introduction

If you are a project or an individual with your own EVM-compatible tokens based on Binance Smart Chain, Ethereum or Polygon, and would like a three-way or two-way bridge to any of these chains, this guide is for you.

We'll walk you through the simple steps needed to deploy your own bridge — and token if you don't have your own token on the secondary chain you wish to bridge to.

Prerequisites

To use our bridge, you will need to have the following:

• The original token's smart contract deployer wallet

  This is the wallet you deployed your first token contract with on Binance Smart Chain, Ethereum or Polygon. If you don't have access to this wallet, then you cannot deploy a bridge.

• Enough ETH, BNB or MATIC to deploy a bridge and token smart contracts

  If your primary chain is Ethereum, make sure you have some ETH in your wallet on the Ethereum chain, and if the secondary chain you are deploying to is Binance, ensure you have some BNB in your wallet on Binance Smart Chain.

STEPS

1. Go to bridgr-testnet.polkalokr.com.
2. Connect your deployer wallet address using Metamask.
3. Click "Create Your Bridge".

Note: We are currently operating a testnet. The Bridgr app will only function with Rinkeby (Ethereum Testnet), Binance Smart Chain Testnet, Mumbai (Polygon Testnet).

Choosing your primary chain

Let's begin by understanding the difference between a primary chain and a secondary chain.

• Primary Chain
• Secondary Chain

Having tokens lock, unlock, mint and burn allows your bridge to control the token supply and ensures tokens beyond your primary chain's total supply are never in circulation.
