BlazeX bridgeHolders move BlazeX between BNB Chain and Ethereum, one for one.

How we built the BlazeX bridge: smart contracts and a web app that move tokens between BNB Chain and Ethereum at a 1:1 ratio, with fees shown up front and a full transfer history.

The challenge

BlazeX existed on two blockchains, BNB Chain and Ethereum. Holders wanted to move tokens between them without selling on one exchange and buying on another, losing money to fees and price swings along the way.

What we built

Move tokens between chains, one for one

  • Bridge smart contracts

    Tokens are locked on one chain and released on the other.

  • A clear bridge app

    Pick the chains, enter an amount and confirm.

  • Fees shown up front

    Network fees appear in tokens and US dollars before you confirm.

  • Full transfer history

    Every deposit and withdrawal is listed with its status.

The results

  • 1:1 transfers between BNB Chain and Ethereum
  • Network fee estimates before every transfer
  • History of deposits, withdrawals and failed transfers

Built with

  • Solidity
  • Web3.js
  • Ethers.js
  • React
  • Node.js
  • Express
  • MongoDB
