Cross chain bridge

app, which executes the ERC20 tokens(eETH, bETH and mETH) between Goerli, Binance Testnet and Matic Mumbai Testnet, and reversely.

The project was built using solidity and hardhat. Contracts are tested with full coverage and deployed on Goerli Ethereum Testnet Network, Binance Testnet Network, Matic Mumbai Testnet Networks

add .env file

npm install
npx hardhat test
npx hardhat coverage

Contract deployments on Ethereum Goerli

npx hardhat run scripts/deploy_gETH.ts --network goerli
npx hardhat run scripts/deploy_bridge_eth.ts --network goerli
npx hardhat grantRole --bridge [bridgeAddress] --token [eETH address] --network goerli

Taks for swap from Ethereum to Binance

1. npx hardhat swapETH --to [address] --value [value] --network goerli
2. then copy values from console for redeem with signature

Taks for swap from Binance to Ethereum

1. npx hardhat swapBSC --to [address] --value [value] --network bsctestnet
2. then copy values from console for redeem with signature

swaps explained

when Swap token from Ethereum to Binance

1. eETH tokens are burn on Ethereum contract by Bridge ETH
2. Signed message is created
3. Reedem function can be run with created previously message, then: Tokens bETH are minted on the Binance network

Swap token from Binance to Ethereum

1. bETH tokens are burn on Binance ERC20 contract by Bridge BSC
2. Signed message is created
3. Reedem function can be run with created previously message, then: eETH Tokens are minted on the Ethereum network
